I seem to be knee deep in rechargeable LED gadgets today, but it's all for the greater environmental good, so bring it on. After the dinky but not really necessary candles comes this far more indispensable gadget. Anyone who's ever owned or borrowed a car knows that an emergency torch is a very, very useful thing. This one doesn't waste energy or require hand cranking either, with the ability to charge quickly in the car's cigarette lighter.

It's hard to believe that a car a little more powerful than the average Bugatti Veyron (if not, reportedly, as well engineered) would run purely on E85 ethanol fuel, but here it is. Leaving aside the long-term concerns about biofuels, that's a move in a sustainable direction that is still unusual for a supercar.
