Specially engineered Flexible Fuel Vehicles (FFVs) can tolerate an E85 mixture of gasoline and ethanol. But will ordinary cars and trucks be able to stand up to the new blend?
For a while, many of us imagined the possibilities: streets full of zero-emission electric vehicles (EVs). But the EV concept has suffered from a certain fragility, and some companies have shifted strategies. Let's talk about a few of them.
What if we could derive energy from crops without killing them or generate power using plants and land not needed for food, all through the power of microbes? Meet the newest, greenest "power plant."

Got your eye on a hydrogen-powered vehicle? The energy of the future comes with some baggage, including an uncanny ability to migrate through metals. Here's what you need to know.
In the future, all of us will own flying cars. Oh, wait -- that's "The Jetsons." Our views of future transportation are a little more realistic, but cars will increasingly use electric power, reducing our dependence on fossil fuels. Right?
Flex Fuel? Ethanol? E85? Been wondering what exactly all of this means? Keep reading to learn about new advances in alternative fuels.
With petroleum-loving masses and tax-happy governments finally getting on board with the development of alt fuels, the race is on to find the cleanest, eco-friendliest, and most importantly, cheapest alternative to fossil fuels.
