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.
A flex engine sounds like some sort of futuristic motor, but you'd be surprised how long this technology's been around. Is it greener or more efficient than a gas-guzzling engine? Flex your brain muscle and find out.
