Each time there is a major power failure in an area, the company is forced to shut down the base station, effectively cutting off thousands of people from service.
The installation of more generators will go a long way in improving the quality of service."
Econet yesterday also assured its customers that measures have since been taken to restore normal supply of recharge cards to the market without delay.
Recharge cards for Econet pre-paid subscriber have been in short supply over the past few days following the increase in tariffs on July 10.
As these measures take effect, the company said customers should expect a dramatic improvement in the availability of airtime vouchers over the next few days.
"We encourage our customers to make more use of these electronic airtime purchase systems, which are more reliable and efficient than buying from street vendors," said the company.
It said the shortages had been due to a range of supplier bottlenecks, which had now been attended to.
Econet has widened subscribers' access to airtime recharge through an extensive electronic value distribution network.
These are a chain of retail outlets nationwide from which customers can easily access airtime electronically via point of sale terminals.
Meanwhile, Mr Mboweni also revealed that the company's international contractors who had suspended work during the election period had all returned, and were now busy with work to expand the network capacity from 800 000 to 1,2 million subscribers.
Mr Mboweni said due to the delays, work that had been originally set for completion by the end of August would now be completed by end of November.

Diesel is killing Nigeria —Oscar Ibru
THE vice chairman, Ibru Organisation, Oscar Ibru, has called on responsible institutions and individuals to commit their resources to better their immediate environment. Two of recent examples are: Mobil Oil that tarred and electrified former Malu Road, Apapa, Lagos a few years ago and Zenith Bank that last year rehabilitated the dilapidated Ajose Adeogun Street, Victoria Island, Lagos. Ibru has just joined them.
Those who pass through the Oshodi-Apapa expressway from Mile 2 to Wharf, since the oil tank farm of Ibru sprang up in the Ibru Port Complex know that the service lane has for sometime now become a “no go area.”
Oil tankers occupy the entire stretch of the service lane from the DTV/Capitol Oil access road end of Mile 2 to the U-turn at Coconut Bus Stop on the Tin Can Island Port complex end of the 10-lane highway, impeding traffic flow on all sides of the highway. But the worst impact is the total deterioration of the service lane on the tank farm side.
It is a matter of divine providence that a fuel laden tanker had not tipped over, spilling its deadly content on the road to cause monumental havoc.
It was to avert such a catastrophic possibility and reduce the stress that his workers and tenants go through daily when going to and returning from their offices that Ibru undertook to rehabilitate the service lane. The stretch of road is about 1,037 metres long. The tarring and clearing of the gutters, overflowing with silt and solid particles, is costing him in excess of N40 million.
His company, Ibru Organisation, brought the tank farm, reputed to be the largest private enterprise of that nature in Africa, to the area. Today, there are over 12 stakeholders of various sizes stocking oil products in the farm. They include major and small oil dealers in the country. The lure is that the complex has a standard port, built in the 70s by Oscar’s father and chairman of Ibru Organisation, Olorogun Michael C.O. Ibru. It is believed to be the first privately owned port complex in the country.
Ibru recognises that the tank farm is the hub of the fuel business of the nation and the access road to the farm should therefore be in top shape for the lumbering tankers to safely move through. “It bothers me to no end that the roads are continuously blocked,” he said in his office at the Port Complex recently. He also dismissed insinuations from some quarters that the tank farm, in which volumes of highly volatile products are stored, is a threat to the neighbourhood. In the last five years or so, more tank farms have sprung up along the same part of the road. There is one beside the Tin Can Island bus stop, along Olorogun Michael Ibru Boulevard (formerly Creek Road).
To such cries of fear, Ibru said that the Ibru Port Complex was built at the present site before Olodi-Apapa expanded to meet it. He explained that when his father acquired the area, it was all swamp. There was no habitation around, even the expressway had not been constructed.
“The Ibru Port Complex paved the way for the development of the area. Those harbouring fear of fire are simply unaware of what the stakeholders have in place. I can assure you that there will be no fire here, we have the equipment, the manpower and the wherewithal to fight any emergency and with the professionalism of our workers and those of the various stakeholders, I absolutely do not foresee any disaster whatsoever happening. Even the Department of Petroleum Resources (DPR) is indeed satisfied with what we have on ground to tackle emergencies,” he said.

Energy crisis: MMA seeks N8bn to acquire generator
Though sources at the airport declined to disclose the capacity of the existing generator, it was, however, learnt it supplied power to both the local and international wings of the airport.
The management of the facility stated that it was ready to revisit the suspended issue of an IPP for all the 21 airports in the country.
When he was contacted by our correspondent on Thursday, the General Manager (Public Affairs) of FAAN, Mr. Akin Olukunle, said that the moves were aimed at finding a permanent solution to the perennial problem of power outage at the airports.
On July 1, a massive power outage at the MMIA occurred when the Power Holding Company of Nigeria cut off its supply.
The PHCN action occurred at the same time when the airport’s generators malfunctioned.
This affected operations, incapacitating the radar and air traffic control and forcing Lagos-bound aircraft to be diverted to Port Harcourt.
The outage also affected the airport’s cooling system, causing the collapse of the air-conditioning system at the arrival and departure halls, such that passengers and other users of the airport had to endure choking heat.
”We cannot afford to be at the mercy of the PHCN all the time,” Olukunle said, adding though that the FAAN management had held talks with the PHCN, which had restored power to FAAN.
Olukunle said, ”Irrespective of that, we are getting new generators. We are going through all the necessary process and we have the support of the Ministry of Transport and the Federal Executive Council. I can assure you that within the present quarter, we will be coming up with something concrete.”
Olukunle said he could not come up immediately with the financial implication of the new generator, but a source close to the technical unit of FAAN said a generator that would replace the present 30-year-old one that serves both the local and international airport, as well as the power requirement of all the organisations that operate within the airport, would cost about N8bn and would have to be manufactured to specification.
“It is not something we can order today and expect it to arrive the next day,” the source said.
Meanwhile, Olukunle said Aisuebeogun, had visited China about two months back, where he held talks with some firms which, he said, had indicated interest in going into partnership with FAAN on its IPP.
”We are still holding talks with them and looking for other investors because it is not just MMIA that we are talking about, but the 21 airports in the country,” Olukunle said.
FAAN‘s recent interest in an IPP is not the first time that the organisation will be making such moves. Early last year, the organisation‘s former MD, Alhaji Muhammad Yusufu, had made the same move and given the same reasons.
Then, Yusufu had noted that “it would be more cost effective for FAAN to build an IPP than to continue to run the airport on generators in the face of the rising cost of diesel.”
Yusufu had lamented that incessant power outage at the airport had destroyed some very sensitive navigational equipment, vital to safe flight operations.

Diesel Generator Compressor Combines Two Products Into One, Space-Saving Unit
Service vehicles and race car trailer owners who want to conserve valuable space have to look no further than Next Generation Power. Their latest product combines a powerful generator and heavy-duty compressor into one, compact unit. The sleek Generator Compressor measures just 42" L x 26" D x 30" H and weighs only 375 lbs.
Now diesel-powered vehicles no longer need to have a separate fuel supply for gasoline compressors and generators. Able to run on the same fuel system, the two-in-one, diesel-powered Generator Compressor produces 20 cfm at 150 psi and 5 kW of electrical power. Operating at a very low 1,000 rpm for longer service life, the powder-coated, belt-driven Schulz air compressor has all CNC-machined parts.
This diesel-powered unit offers a longer life, lower maintenance and better fuel efficiency than gasoline. Tried and trued, the efficient Next Generation Power gen-set features a durable, 2-cylinder Kubota Z482 engine. Water-cooled, it runs at mid-speed, peak torque at a comfortable 2,800 rpm. A vortex combustion system creates greater energy output with less fuel consumption and cleaner burning exhaust.

Diesel shortage hits Nagpur
In what is being termed as a fallout of rising crude prices, the city is facing an acute shortage of diesel.
Except a handful, all major filling stations within city limits ran out of diesel on Sunday. Customers were being directed to outlets outside city limits, but there is no guarantee one would find diesel there, said pump owners.
They said that most diesel outlets ran dry on Sunday after three or four days of low stocks, with quite a few having run out of diesel a couple of days ago.
Petroleum dealers said that with almost every car brand having a diesel version, several four-wheeler owners were finding it difficult to refill their tanks as they were turned back at almost all local pumps. With load-shedding also going up by another hour from Saturday, those running diesel generators too are finding it hard to find enough diesel to run their sets, say the dealers.
However, the exact reason for this sudden shortage is unclear. Retail outlet owners say that the oil companies have fixed a monthly quota of fuel since the last month for every petrol pump.
"This is the reason supplies have shrivelled substantially," they said. The quota has been fixed according to the monthly average of diesel sold at the particular pump in the last one year, said dealers.

Letter: Nuclear power for Cayman
At the moment, Cayman, other islands, and remote areas that are dependent on diesel generation are being strangled by the rising cost of oil. All the signs point to a continuing and deepening world supply-demand crunch.
We all need a viable alternative to burning oil for power generation.
Finally, after many years of sitting on modular nuclear reactor designs for years, the world is starting to move toward building and marketing some of them.
A company called Hyperion Power Generation was formed recently at the Los Alamos nuclear laboratory. It is already funded and expects to start delivery of units beginning in 2012.
The units are about the size of a large bathtub and can generate 70 megawatts (thermal) or 25 megawatts (electrical) for 7 to 10 years, and cost $25 to $30 million. They are self regulated, are clean burning, have no moving parts, and the amount of waste after 7 years of operation can fit in a softball.
The self-regulation is provided by the laws of physics operating in the core, not by control rods or any other kind of neutron absorber. And, rest assured, the laws of physics never change.
The company is taking orders now, for delivery in 2013. With our electrical load now nearing 100 megawatts, two or three of these units could supply CUC’s base load.
CUC’s existing diesel generators would only have to run to supply the peak load.
Twenty five megawatts for 7 years is 1,533 million kilowatt-hours. A gallon of oil contains 45 kilowatt-hours (thermal) or about 16 kilowatt-hours when burned in a 35% efficient diesel generator.
If $30 million can buy 1,533 million kilowatt-hours, the cost is 1.9 cents per kilowatt-hour, and this is worst case. If the best case is assumed, the cost drops to about 1 cent per kilowatt-hour.
Of course, these costs do not include the capital cost of the steam generator and turbine-generator. But once installed, the cost of these is only to service the debt and some very small cost per kilowatt-hour for maintenance.
Given these numbers and the projections for oil prices, it is not too soon for CUC to negotiate a place in line for some of these units.

Balloon festival to go on despite rising fuel costs
Despite rising fuel prices, the show will go on next month at the Metro NY Balloon & Music Festival at Broohaven Calabro Airport in Shirley.
Newton Shows, an East Northport company, will provide the amusement rides, all of which are powered by diesel fuel. A year ago, Mike Newton, who co-owns the company, said he paid close to $3 a gallon for diesel. This year, local prices have climbed to more than $5 a gallon.
"It did throw us off, but the show must go," Newton said. "You almost can't even look at it. You hope that you have a good season and that revenues keep up with expenses."
Last year more than 120,000 people attended the show, which this year runs Aug. 8-10. Besides amusement rides, the festival - which real estate company Re/Max of New York Inc. is producing - features hot air balloons, monster-truck shows and live entertainment.
Newton Shows provides the amusements for the midway, which will feature more than 30 rides and games. Three generators will provide the juice for that entertainment, which includes Pharaoh's Fury, a giant swinging boat, and Super Shot Drop Tower, a ride with a 90-foot descent, Newton said. Each generator uses about 18 to 22 gallons of diesel an hour.
Because of the spike in fuel prices, Newton raised the pay-one-price ticket to $30, from $25 last year. (The festival's general admission price remains at $20 prepurchase and $25 at the gate.)
Newton said he may try to conserve fuel by not running all of the carnival lights during the day. Other than that he is hoping a bigger turnout will help offset his higher fuel bills.
"You just try to work with a great sponsor like the Balloon Fest and our other sponsors to draw people to keep revenues healthy enough to overcome the additional expense," he said.
And he is expecting a higher turnout because of - guess what? - higher fuel prices.
"We're expecting more people because they can stay close to home and enjoy a fully loaded, family friendly and affordable event," Newton said.

Diesel Generators Explained
A diesel generator is composed of a diesel engine and an alternator or an electrical generator, which converts the power created by the engine (expressed in RPM, revolutions per minute) into the required voltage for homes, industry and remote work sites. The need for power for homes and sites, which are not connected, to a power grid is a growing need throughout the world. Remote areas of Central and South America are no longer too poor to afford electrical power but not at the stage to built vast hydroelectric projects or large power grids.
They can afford to build local village electrical power plants, which can meet the modern needs of the people until the modern power grid can reach out to them. There are places in the United States that are developing ahead of the ability of the local power company to expand; other places throughout the world are at the edge of civilization. All of these require power for business, commerce, medical treatment facilities and communication. The price of the modern diesel generator, the new technology incorporated into these units and their availability throughout the world make them an immediate solution.
Homes and ranches, villages and towns and remote sites should create a power needs list that includes every appliance in the home, business, school and public facility in order to determine the wattage needed. After this the home or ranch owner, city engineer or site foreman can select the proper sized diesel generator. Every diesel generator is rated at how many kilowatts of power it produces. If the home or ranch requires 22 kW to 25 kW then the sized generator should be at least a 30kW. A brigade sized army unit twenty years ago used a diesel generator(s) rated at 90 kW but its’ needs were lighting and mess hall refrigeration. Today it could be quite a bit more considering the new technology.
When you decide to provide power through diesel generators then you should consider whether you need a backup. The power of the generator is rated at 50% engine speed. The 30 kW diesel generator actually operates safely at 25 kW at 1800 rpm for prolonged periods of time. It would be safer if the home or ranch had two generators scheduled to operate in an alternating schedule of 12 hours each. This would ensure that the proper maintenance and care could be given the generators while providing continuous power. Other considerations in selecting a power generator involve selecting one that is a four-cycle, water-cooled industrial diesel generator.
A water-cooled generator operates more quietly than an air-cooled and it lasts longer. There are two electrical systems involved with a diesel generator, the DC (direct current) and the AC (alternating current) systems. The recommended DC system should have a starter motor with a battery-charging alternator with a solid-state voltage regulator. It should have an engine pre-heat electric switch and start/stop switch.
It should have an emergency engine shutdown system to protect the engine in case of oil pressure loss, excessive generator speed, over cranking and engine high water temperature. Finally, it should have DC electric system breakers. Make sure that the AC system is a four-pole revolving field and is has an AVR (automatic voltage regulator). These generators will provide power that is within -+2% as compared to utility company variation, which is -+5%.

Lagoon 420 – Diesel Electric Sailing Vacations
Interested in finding out what the future in yachting will be like? The best way to get a close and personal introduction into diesel electric yachting is through chartering one of these “Green” yachts. The Tortola Catamaran Center will be able to give you this opportunity through their acquisition of a Lagoon 420, called “Dignity”. This kind of propulsion system makes minimal noise, and does not create smoke.
The Lagoon 420 is the perfect example of what happens when luxury and technology work together. Space and comfort were not limited in the design of this boat. The large master cabin is in the port hull. The other cabins provide substantial room for crewmembers. This catamaran is not run short of storage area. Privacy can be easily attained since all cabins can be closed off from the salon.
Experience all of Lagoon’s innovations on an environmentally sound vessel. “Dignity’s” electric propulsion system consists of two standard electric motors connected to propellers by straight shaft transmissions, one generator and two set of 6 batteries.
Even while this vessel is running on the electric system crew members can rest assure that they are not creating any pollution? This system is so advanced that the batteries actually charge while the vessel is sailing. Regeneration occurs on the downside of waves. The generator provides electricity for the motors, the batteries and the daily boat needs (air conditioning, power sockets, washing machine, etc.). This arrangement creates energy savings for you. Experience what it’s like to enjoy sailing the ocean in a 21st century electric catamaran. The fact that you are sailing in a non-polluting vessel will mean enjoying Mother Nature without damaging it.
When batteries are 100 % charged, the boat will be able to function with both motors for approximately two hours (depending on speed). When batteries are 80 % charged, the generator will automatically start and charge the batteries in order to provide electricity for the motors.
Be one of the first to participate in the future of sailing.

Why Small Diesel Generators Top The Emergency Power Generation Class!
Small diesel generators have become an essential household item for many families throughout the United States. In areas prone to hurricane, tornadoes and severe winters, small diesel generators provide life saving aid. One only has to live through a power outage lasting several days in below freezing conditions to realize how difficult life would have been without one of these superb little machines.
Small diesel generators have always had wide acceptance within industrial, rural or building applications. However, with the advance in diesel technology and the small engine over the past few years, diesel is fast becoming the preferred option for household generator owners. These small compact units are not only safer to operate, but they are now much quieter and last much longer than their petrol counterparts.
The reality of small diesel generators being incredibly noisy and smelly is now fast disappearing. One only has to look at sales figures of these engines to the domestic market over the past couple of years to realise how quickly this has happened. More and more home stand-by generators are now diesel powered.
Suburbia, particularly in those areas that are prone to power outages through one reason or other has become inundated with diesel generators of latter years. This has historically been the domain of the small petrol generator which was relatively lightweight and easy for the home handyman to operate. In the wrong hands though, the toxic emissions from these types of generator have proven to be deadly. Safety for many people is reason enough to change to the small diesel generators. The exhaust fumes are not nearly as toxic as those that are emitted from gasoline engines. The fact that they require less maintenance is also another main reason for the change. No ignition system, carburettor or spark plugs means that there is far less that can go wrong.
In a stand-by situation the small diesel generator shows why it is so good. It is built to work for hours on end, in fact the harder it has to work the better it likes it. Gasoline generators on the other hand are more than likely going to self-destruct if put to the same kinds of tasks as the diesel generators. They are designed for intermittent use and when working under load they are also usually very noisy. Homes today are also not the simple affair that they used to be. Now fitted with modern electronic devices, they require a back-up power system that provides high quality stable power. Small diesel generators provide this quality that protects this sensitive equipment from damaging power surges.
The only real downside with the small diesel generators is their initial cost. This cost though much greater will soon be offset by the lower maintenance costs, and the long problem free life that you can expect. Ten to fifteen years is not an unreasonable life expectancy of a small diesel generator providing regular maintenance requirements are carried out.

Benefits Of A Generator Sitemap
Generator sitemap programs can be downloaded from various sources on the Internet. Generator sitemap programs have two fundamental purposes. Generator sitemap programs help surfers navigate a site effectively. At the same time, a generator sitemap program encourages search engine spiders. Google offers one of the most popular generator sitemap programs ever to hit the Internet.
The generator sitemap of google makes it possible for a website to get listed and get updated by the google search engine. Setting up the generator sitemap helps speed up the addition of the web pages of a site to the google listing. The generator sitemap also makes it easier for a site to get noticed by online surfers. In addition, any changes made to a website that has a generator sitemap is immediately picked up by google. The generator sitemap also helps keep online information fresh and up-to-date for users.
Visibility is key to generator sitemap
Visibility is a major concern when using a generator sitemap. A website that is completely indexed has better chances of getting top search engine placement in page results. Many of the popular browsers used by searchers and that support java recognize generator sitemap programs. These include firefox and Internet explorer.
An online consumer that searches for a specific content on the web can immediately be directed to any one of the web pages of a particular site. The generator sitemap makes it easier for a search engine to provide accurate results from web pages they are familiar with.
Who can benefit from a generator sitemap?
A generator sitemap is highly recommended for websites that often do repeated modification of their web pages. A generator sitemap can be used for websites of any size, regardless of the number of web pages a site may contain.
Although using a generator sitemap is not a guarantee of increased site rankings, it does however provide a website a better opportunity of getting listed on a search engine.
Working with a generator sitemap
Most of the available generator sitemap programs available on the web make use of extensible markup language or XML. Similar to hypertext markup language or HTML, XML is used widely in blogs and syndicated feeds on the Internet. Each line of a XML code for a generator sitemap has a specific purpose.
The location or .loc identifies the name of the web page of a website. The line .lastmod indicates when the web page was last modified. The format for .lastmod can either be dd.mm.yyyy, dd.mm.yyyy hh:mm, dd/mm/yyyy or dd/mm/yyyy hh:mm. Shortcuts can also be used to simply the assignment of dates to the cell.
.changefreq advises the search engine of a specific time frame when the web page is regularly updated. This can either be done on an hourly, daily, weekly, monthly or yearly basis. For web pages that are not updated, the value 'never' is used. .priority indicates the level of priority that a search engine should give a particular web page of a website. These levels range from 0.0 for least priority to 1.0 for high priority.
Creating a dynamic generator sitemap
Creating a dynamic generator sitemap is useful for websites containing various web pages. The google search engine makes it easy for users to adapt their google sitemap with the help of a python script.
The python script generates a sitemap using sitemap protocol. This creates a sitemap from either access logs, URL lists or from web server directories.
Tips for using a generator sitemap from google
As one of more popular search engines offering a generator sitemap for websites on the Internet, google offers a few tips for its loyal users. Using the google sitemap url encoder/decoder is helpful for submitting sitemaps to google. For websites that have numerous web pages, creating a sitemap can be a tremendous task. For this situation it is best to click on the column title in order to make it easier for a URL list to get sorted.
The google generator sitemap allows users to save their settings after creating a sitemap. Users can use these saved settings as a guideline for succeeding generator sitemap updates. The generator sitemap also recognizes the use of robots.txt files.

Homebuilt Wind Generator Power
One hot summer afternoon, someone decided to test their craftsmen ship and take it upon themselves to make a homemade wind generator. It surprisingly took under $100 to make this wind generator. Although it does not work quite as well as a commercial bought generator and it would not hurt the design to have a few improvements.
If time is not a problem and you have a really flexible schedule then this could be something for you to try as well. However if you do not have a lot of time and have some expendable money then you can go buy a commercial generator prices vary and will save you a lot of time. However if you want to save yourself a couple of hundred dollars then try this out.
The propeller chosen for use on this machine has a 3 bladed design. It was made out of spruce 1" X 4" boards that were knot free. If you use a propeller that is not too heavy then this helps the machine start up faster and can help preserve the bearings on the generator. As for the alternator, the one chosen was a 2 horse power induction motor that he took off a Taiwanese milling machine. He used a four pole motor therefore it needed 4 alternating poles in the alternator. The most important part and also sometimes the must neglected is the tower. A high tower is needed and he used a pine tree for this which is supported by 4 guy wires which are 1/8" diameter aircraft cable with turn buckles on the ground that are used for adjustment.
If you choose to build your own home generator you get the reward of satisfaction and also get to save some money. It is always good for people to provide results of their own personal experiences of building their own machines. It will help give other people ideas on how to build their own wind generator at home.

Diesel or Petrol? Take Your Decision!
Have you ever played snakes and ladder?
Two opponents playing at a similar pace and suddenly one falls due to snake bite. Similarly petrol and diesel are actively having a cut throat competition between them. They play on similar grounds but as we say the demand curve keeps changing. They never know when they will climb the ladder of success at one step and be thrashed by venom on the other step.
Tata Indica Diesel and Tata Indigo Diesel are good example of diesel cars. The debate on choosing between diesel and petrol is never ending. There are few factors to be considered to make the choice easier.
Before accelerating the discussion further, let’s break a little to check out the speed breakers.
• Speed: Now if we compare petrol cars and diesel cars, the speed of petrol cars is much better. They are fast speed cars.
• Fuel consumption: Diesel cars have better fuel consumption ability which gives a good pulling power to the car. And of course there is less gear changing in this case.
• Mileage: In case of high mileage driving Diesel cars are easier to sell than a petrol car.
• Carbon dioxide: The emission of carbon dioxide is very unhealthy for our environment. It leads to global warming. The fuel consumed by diesel cars is 30 to 40% less than petrol cars, so diesel cars produce less carbon dioxide.
• Hydrocarbons: It contains very harmful chemical called benzene. It is produced more by petrol engines then diesel engines.
• Particulates: Diesel engines emit more PM10 particles that are particles which have a diameter up to 10 microns. These are invisible particles which penetrate into human lungs and cause a lot of health issues.
• Cost: As far as cost goes, a petrol motor has an advantage even before you drive out the showroom doors. The diesel option - particularly a turbo-diesel - can add thousands of rupees to the already high price of a four-wheel-drive.
• Running costs: A comparison of the running costs for petrol and diesel engines will often find the petrol models are cheaper - aside from fuel. Diesel models will normally require more frequent engine oil and filter changes.
• Cost of fuel: A petrol vehicle is a very thirst vehicle. The diesel vehicle wins the race where fuel economy is in stake. A diesel engine will use mere fraction of the fuel as compared to a petrol engine doing the same job.
• Carbon monoxide: It is a deadly poison and kills without even letting us know. A diesel engine wins in this situation as it does not produce carbon monoxide. Though catalytic converters are trying to solve the problem of carbon monoxide in case of petrol engines.
• Refinement: Diesel engines have always been very noisy in comparison to petrol engines. Though the new models of diesel are no doubt a better version but still there is a lot of scope to improve.
• Smooth drive: A petrol engines acceleration response is more desirable. Diesels particularly naturally aspirated ones need more input from the gear box to maintain the traffic flow.
• Performance: Some time back diesel engines gave poor performance as compared to petrol engines. But with the coming up of turbo chargers the situation has fairly improved.

Bio Diesel Fuel - An Energy Source Now and for the Future
Bio Diesel fuel is a diesel equivalent, processed fuel derived from biological sources, such as vegetable oils, which can be used in unmodified diesel engine vehicles. It can also be used as a heating fuel in domestic and commercial boilers. There are a number of naturally occurring and renewable resources it can be refined from including algae, vegetable oils, animal fats or recycled restaurant greases. It can also be processed where ever the raw materials to make it exist.
Bio diesel fuel is nearly completely free of sulfur and aromatics and is a naturally oxygenated fuel because it is composed of almost 10 percent oxygen. Because of this biodiesel provides a significant reduction in particulate and carbon monoxide emissions then petroleum based diesel fuel.
It is also safe to handle and transport because it is has the biodegradability of table sugar, is 10 tens less toxic then plain salt, and has a high flashpoint, the temperature at which it catches fire, of 300 degrees Fahrenheit as compared to regular diesel fuel which flashes ate 125 degrees Fahrenheit. Bio diesel can also be blended with petroleum diesel to create a biodiesel blend as well as its ability to be used in almost any diesel engine without any modifications.
Many gas stations are beginning to make biodiesel available to consumers and a growing number of transport fleets are using it as an additive to their fuel. It is important that fuel grade bio diesel be refined to tight industry specifications in order to ensure proper performance. One of the benefits of this fuel is it lower engine wear. In fact some vehicle manufacturers are beginning to make engines specifically for bio diesel for this reason.
Because it is a better solvent then regular diesel it tends to clean the engine when first used and removes deposits from the fuel lines which can clog fuel injectors. After switching to biodiesel most car manufacturers recommend changing the fuel filter to help prevent this. Use of this fuel leads to lower engine emissions while improving engine lubrication. Many government fleets on the federal and state level as well as utility fleets are now required to purchase 75 to 90 percent alternative fuel vehicles these days. Since biodiesel is the lowest cost alternative fuel option many of these fleets are converting to its use.

Diesel Pusher or Gas Powered Motor Coach
Do you know the difference between a diesel pusher and a gas powered motor coach? If you are in the market for this top of the line Class A recreational vehicle it will be important for you not only to know what the differences between a diesel pusher and a gas powered motor coach are, but also which one would be best for you and your budget and lifestyle. Many future RV owners may think that cost is the most important factor, but you should also consider power and features as well. The diesel pusher has many qualities which may make it a more appealing and practical choice for your RV.
Don’t be put off by the price tag you see on some diesel pusher models. The top of the line models are generally more expensive than gas powered, but they are also the most luxuriously equipped. Manufacturers do this to appeal to their high-end clients. However, it is also possible to get a smaller or more basic diesel pusher for a price that is comparable to a gas-powered Class A. But remember, the most basic Class A RV is still the most spacious and luxurious recreational vehicle on the market.
A diesel pusher is more fuel efficient and powerful than a gas powered RV. The fuel tank is generally larger as well. This is important if you are planning on towing a car or boat behind your RV. You can also travel farther and up steeper mountains with less engine strain if you have a diesel engine.
Whether you choose a gas or diesel powered motor coach, you will find that they are roomy and have lots of storage space. This makes them appealing for families and people who plan to spend a lot of time on the road. They are fairly simple to drive and maneuver if you have a little practice.

For example, any channel can be synchronized to an external trigger (To), internal trigger (also To) or the leading edge of any other channel (T1 thru Tn). The channels operate in modes independent of the other channels. Mode availability includes gated, enabled, burst, single shot, normal, duty cycle (divide by N).
The Model 565 digital delay generator or Model 505 pulse generator also operate in triggering modes common to all channels. A continuous mode provides pulse periods with 500 ps and 100 ns resolution, for the 565 Digital Delay Generator and 505 Pulse Generator respectively. This allows orders-of-magnitude finer control of the triggering interval than with a frequency controller. A single-shot mode produces a single pulse with each pushbutton or each external trigger. A burst mode produces a burst of pulses selectable from 1 to a million. The duty cycle mode provides M pulses on and N pulses off (divide by N, if you want). Both Models provide the ability to store several complete setups into memory for future recall. The Model 565 digital delay generator supports RS232, GPIB, Ethernet and USB programming. The 505 pulse generator supports RS232 and GPIB. The 565 has 3 output selections; the 505 offers one. Standard with the Model 565 Digital Delay Generator are a fast logic output, an adjustable level up to 12 V, and an optional 35 V. The Model 505 Pulse Generator offers an adjustable level up to 20 V.

Channels for the Model 565 Digital Delay Pulse Generator and 505 Pulse Generator can be selectively gated, enabled or disabled with each channel delivering selectable output polarities and an independently adjustable level. These models also allow the selection of a reference to which each channel is synchronized. For example, any channel can be synchronized to an external trigger (To), internal trigger (also To) or the leading edge of any other channel (T1 thru Tn). The channels operate in modes independent of the other channels. Mode availability includes gated, enabled, burst, single shot, normal, duty cycle (divide by N).

Diesel or Petrol? Take Your Decision!
Have you ever played snakes and ladder?
Two opponents playing at a similar pace and suddenly one falls due to snake bite. Similarly petrol and diesel are actively having a cut throat competition between them. They play on similar grounds but as we say the demand curve keeps changing. They never know when they will climb the ladder of success at one step and be thrashed by venom on the other step.
Tata Indica Diesel and Tata Indigo Diesel are good example of diesel cars. The debate on choosing between diesel and petrol is never ending. There are few factors to be considered to make the choice easier.
Before accelerating the discussion further, let’s break a little to check out the speed breakers.
• Speed: Now if we compare petrol cars and diesel cars, the speed of petrol cars is much better. They are fast speed cars.
• Fuel consumption: Diesel cars have better fuel consumption ability which gives a good pulling power to the car. And of course there is less gear changing in this case.
• Mileage: In case of high mileage driving Diesel cars are easier to sell than a petrol car.
• Carbon dioxide: The emission of carbon dioxide is very unhealthy for our environment. It leads to global warming. The fuel consumed by diesel cars is 30 to 40% less than petrol cars, so diesel cars produce less carbon dioxide.
• Hydrocarbons: It contains very harmful chemical called benzene. It is produced more by petrol engines then diesel engines.
• Particulates: Diesel engines emit more PM10 particles that are particles which have a diameter up to 10 microns. These are invisible particles which penetrate into human lungs and cause a lot of health issues.
• Cost: As far as cost goes, a petrol motor has an advantage even before you drive out the showroom doors. The diesel option - particularly a turbo-diesel - can add thousands of rupees to the already high price of a four-wheel-drive.
• Running costs: A comparison of the running costs for petrol and diesel engines will often find the petrol models are cheaper - aside from fuel. Diesel models will normally require more frequent engine oil and filter changes.
• Cost of fuel: A petrol vehicle is a very thirst vehicle. The diesel vehicle wins the race where fuel economy is in stake. A diesel engine will use mere fraction of the fuel as compared to a petrol engine doing the same job.
• Carbon monoxide: It is a deadly poison and kills without even letting us know. A diesel engine wins in this situation as it does not produce carbon monoxide. Though catalytic converters are trying to solve the problem of carbon monoxide in case of petrol engines.
• Refinement: Diesel engines have always been very noisy in comparison to petrol engines. Though the new models of diesel are no doubt a better version but still there is a lot of scope to improve.
• Smooth drive: A petrol engines acceleration response is more desirable. Diesels particularly naturally aspirated ones need more input from the gear box to maintain the traffic flow.
• Performance: Some time back diesel engines gave poor performance as compared to petrol engines. But with the coming up of turbo chargers the situation has fairly improved.

Darwins Theory of Diesel Performance!
If Darwin himself were alive today I dare say that he would be driving a diesel. No other engine out there has more perfectly illustrated his theories of evolution than the diesel. Now as true as it might be that diesels were once known for being the “slow and smelly” vehicles on the road car makers as well as several performance companies have set out on a mission to put an end to that reputation. With the additions of a turbo or multiple turbos (i.e. '08 Powerstroke) and intercooler(s) as well as intakes, chips/modules and exhaust systems the reputation once held by diesels is now evolving, Darwin would be so proud.
So why diesel performance? In the past there never really was a question as to which “species” was more dominant when it came to performance. It has not been until recently that there has even needed to be a debate as to which is better, gas performance or diesel performance and even today you will have people try to argue that gas performance is where it is at but I am here to say that not only is there more horsepower available for the money when it comes to performance products for diesels but you will have longer engine life as well as maintain if not increased fuel mileage.
One of the strongest points in the argument for Diesel Performance is the fact that you can add engine mods to a diesel engine and it won’t harm the engine or make it burn hotter to the extent of damaging the engine permanently. Don't get me wrong you can still fry your engine but diesel engines are built much stronger and much more durable. One of the main reasons that diesel engines are so durable or will last longer in general is the way that combustion occurs in the engine. Diesel engines “fire” or “combust” differently than gas engines mainly because of the type of fuel that is used. In gasoline engines a spark plug is used to combust the fuel but in a diesel combustion occurs mainly due to the temperature of the compressed air which causes the fuel to ignite. Because of this diesel engines are built more durable because they have a higher compression ratios (20:1 for a typical diesel vs. 8:1 for a typical gasoline engine) it is being built to withstand this higher compression that makes these engines more ready for performance modifications straight from the factory.
As the diesel engine has evolved over the years turbo chargers have been added to increase power as well as efficiency, this has made way for huge increases in horsepower both stock as well as with the addition of after market products. One of the main reasons that diesel performance is so much more viable is the fact that because the engine is built for a higher compression ratio anyway so it is going to be able to withstand the boost that is created by a turbo much better than a gasoline engine, also allowing the addition of performance modifications without shortening the life of the engine as usually happens with gasoline engines when performance mods are added.
