"The day after 9/11, I began changing my habits for the better and ever since then I've looked for methods to improve fuel economy," Gerdes told LiveScience. "We all have our trigger points — mine was global security. It doesn't matter if you're concerned with global warming, or smog, or government debt, or if you're worried about putting money in your pocketbook. All those reasons are good reasons to become a hypermiler."

A nice car gas saving tips written with unique style

As you know, gas prices go up every day. Many years ago we could buy a gallon of gasoline for only $1. And how much does it cost now? More than $4 per gallon. That's why so many people have been looking for a way to increase gas mileage and save money. And finally, inventors have found a solution of this problem.

With the recent increase in fuel price, it has become absolutely necessary for everyone to get an alternative source of fuel that may be complemented with gasoline and diesel in order to decrease the amount of money spent on fueling our cars. As we speak, there is a new technology that can help us to solve that problem. Before you say: "Yeah another costly alternative", read this run your car on water review.

It's true, you can run your car on six gallons of water...

Read what GM Chairman, Rick Wagoner, thinks about the role of ethanol in the bridging the imposing canyon separating today’s petroleum needs with tomorrow’s hydrogen-powered electric hybrid promises.

Good news to those that can afford it. Porsche promises the Panemare to be offered in a hybrid flavor when it finally bows in 2009, with a 30-percent boost in fuel economy.

Supposedly, the much anticipated ratcheting up of car fuel efficiency standards will force more people to downsize their rides and purchase more fuel-efficient cars. I don't buy it.

Since he was a teenager, Takeshi Uchiyamada's dream was to make a car. But as he entered his 50s as a Toyota engineer, he had all but given up hope he would ever head a project to develop a model.

In the hypercompetitive world of Formula 1 motor racing, the only thing greater than the level of technology is the money spent developing it, and a lot of that money is about to be invested in green technology that will appear in cars the rest of us drive.

Malaysia, Thailand, Colombia, Uruguay and Ghana are poised to become the world leaders in biodiesel production, according to a new study.

The Equinox fuel cell cars run solely on hydrogen, which, at this point in time, is a drawback for the average consumer. Although we produce 40 billion kilograms of hydrogen globally every year--enough to power 130 million fuel cell-powered cars--hydrogen fueling stations are still scarce.

"They could do all this stuff if they wanted to. ... The technology has been there forever. They make 90% of the components I use... I've just been messing around and seeing what I can do. ... Everybody should be driving a plug-in vehicle right now. ... I can go next door to Ace Hardware and buy a DC electric motor, go out to my four-wheel-drive truck, remove the transmission and engine, bolt the electric motor onto the back of the transfer case, put a series of lead-acid batteries up to 240 volts in the back of the bed, and we're good to go.

"Americans can make a difference in the fate of the penguin population by leaving the car at home and taking a motorcoach," Pantuso said. "Motorcoaches reduce congestion and pollution by taking more than 425 million cars off the road each year. Coaches provide the same congestion mitigation benefits as transit buses in that we have the capacity to take up to 55 cars, per coach, off the road at one time."

So, is this the most aerodynamic car you've seen all day? For one student, Elle Kalm, it's the cleanest air-slicing vehicle that's feasibly possible, at least according to Kalm's recently-published paper. The paper, which was published in August, is a Master's thesis on the design of an aerodynamic green car.
