The stars of the show were diesels, and 2009 will see a raft of them launched into the U.S. market—not just from German diesel stalwart Mercedes-Benz but also Audi, BMW, and Volkswagen. Audi showed its stunning R8 supercar with a turbocharged V12 diesel, similar to one that won LeMans, making it undoubtedly the fastest and sexiest diesel in the world.

In effort to move along the environmental message, British Liberal Democrats announced plans to abolish both gasoline and diesel powered vehicles by 2040.

A hybrid electric train built by Bombardier just took its inaugural trip in France. Diesel locomotives have always been a kind of hybrid -- their diesel engines charge batteries which power a gigantic electric motor. But this new train can run on electric power from any source available (not just the engine.) The trains will be charged with grid power, and will produce roughly 20% less CO2 than non-hybrid versions.

Aptera has listed the full electric at $26,900 and the diesel hybrid at $29,900. As noted, the diesel hybrid will be a series plug-in, just like the impending Chevy Volt. This means that the car will run 100% on electric power, but a diesel engine will charge the batteries when they get low.

MARS can complement a diesel generator by offering a combined diesel-wind power solution that delivers power below 20 cents per kWh. This compares to a wide range of 25 cents to 99 cents per kWh for diesel-alone, reflecting the high fuel and transportation costs in remote areas

Although the mention of a magnetically levitating train outside of US borders won't grab too much attention, saying that phrase here most definitely perks up ears.

oyota's heavy duty division, Hino, is testing a new kind of plug-in hybrd...one without a plug. The batteries on the hybrid assist and even sometimes take over for the diesel engine. But the energy in the batteries doesn't come from a plug, it comes from a wireless charging system built into the road.

The air quality of urban areas would greatly improved if we could replace the thousands of diesel delivery trucks currently in use with zero-emission vehicles. In this vein, a company called  Smith Electric Vehicles will be introducing their electric trucks to the U.S.  Their Newton truck (pictured above) can be recharged via an regular electric socket. They have some pretty impressive features, including a range of up to 150 miles when fully charged. The battery system is rated at 120 kilowatts, and trucks have a maximum speed of 50 mph. The trucks also use regenerative braking to recover energy from the braking process.

7 January 2008—At first blush, you might lump claims about a machine that supposedly turns sunshine, air, and water into fuel in the same category as e-mails insisting that someone in Nigeria will pay you handsomely to help free up a large sum of money. But researchers at the U.S. Department of Energy’s Sandia National Laboratories, in Albuquerque, say they have created a device that can break water into hydrogen and oxygen using sunlight, or in a another reaction convert carbon dioxide, to carbon monoxide that combines with hydrogen to make hydrocarbons such as methanol, ethanol, and even gasoline or diesel fuel. The technology holds the promise of using the same resources as biomass-to-fuel schemes but with potentially greater efficiency, according to the researchers.

IF smog-choked streets test our love for petrol and diesel engines, then rocketing fuel prices and global warming could end that relationship once and for all. But before you start saving for the fuel-cell-powered electric car that industry experts keep promising, there's something you should know. The car of the future will run on metal.

So what is the Loremo? Is it electric? Hybrid? Neither. This puppy is a diesel -- hard to believe considering it gets 118mpg! The people at Loremo have done it simply by reengineering the design of the car from a the perspective of weight management.

Thermoelectric energy conversion is a solid-state technology that is environmentally friendly. One of the more promising ‘down-to-earth’ applications lies in waste-heat recovery in cars.”Tritt said more than 60 percent of the energy that goes into an automotive combustion cycle is lost, primarily to waste heat through the exhaust or radiator system.“Even at the current efficiencies of thermoelectric devices, 7 to 8 percent, more than 1.5 billion gallons of diesel could be saved each year
