Automaker Volvo has unveiled seven trucks that the company sees as the future for long-haul transportation in the country.
This story in Land Line Magazine says Volvo officials debuted the trucks at the Washington International Renewable Energy Conference in Washington, DC:
The trucks, powered by everything from biodiesel and ethanol to biogas and hydrogen, are touted by the company as being carbon dioxide neutral. That means they don’t add any carbon dioxide to the air through the combustion process.
A number of concerns, including skyrocketing fuel prices, the realization that fossil fuels won’t be around forever, and climate change prompted Volvo officials to prove that trucks could be run on virtually any type of renewable fuel.
Volvo Group CEO Leif Johannson said by building trucks that can run on alternative and renewable fuels, Volvo addresses uncertainty that political leaders may have as they move forward on policies that will reduce dependence on fossil fuels.
“I used to say we could run a truck on anything, even vanilla sauce,” Johannson said with a laugh during a roundtable discussion following the unveiling. “We can’t do that, but that’s about the only thing.”
The trucks run on biodiesel, synthetic diesel, methanol/ethanol, dimenthyether, biogas, and hydrogen (some of them even run on a combination of different fuels).
Volvo officials want to make sure they are prepared… no matter what the alternative fuel of choice will be.

A Minnesota company has developed a process to convert waste beverages into fuel.
What’s being billed as “the premier technical conference for solar energy and energy efficiency professionals in the U.S.,” SOLAR 2008 is set for May 3rd-8th in, appropriately enough, sunny San Diego, California.
To do that, he mentioned just about every alternative, domestic energy source possible – from ethanol and biodiesel to wind and solar, hydrogen and nuclear. He discussed the need for vehicles that run on alternative fuels, including plug-in hybrid electric vehicles, and he visited with manufacturers of those types of vehicles at the WIREC trade show.
Using 40 pairs of vehicles commonly found on American roads, a year-long research effort found that increasing ethanol blends from 10 percent (E10) to 20 percent (E20) in a gallon of gasoline provided an effective fuel across a range of tests focusing on drivability and materials compatibility. 
Legendary British carmaker Bentley says it is it will look to ethanol, lighter construction and more efficient gasoline engines… instead of diesel and hybrid motors… to meet the green demands of the future:
A group is trying to combine their faith with its desire to live a life that will allow everyone to enjoy the Earth before they have to head off to Heaven.
A French carmaker is introducing a truly unique vehicle to the North American market… one that runs on air!
Developed by Formula One race car engineer Guy Negre, the Air Car is equipped with a revolutionary dual-energy compressed air engine, achieving a fuel efficiency of 106 miles to the gallon. At low speeds, this vehicle emits only air from its tailpipe making it a good option for ‘green’ inter-city traveling. The Air Car is built with Compressed Air Technology (C.a.t.) and is designed to be relatively affordable, as it is estimated to cost approximately $18,000 and to consume only small quantities of fuel.

According to their calculations, Hickman says the United States could produce a 15.6 billion bushel corn crop seven years from now. “If we grow as much corn as we did in 2007 and the yield increases go from where they have in the last ten years, that would be possible in 2015,” he said. “That could then produce 19 billion gallons of ethanol and still provide exports and other uses for corn.”
