New thermoelectric material could extend a gallon of gas


Now that gas prices are so insanely high, scientists are revisiting many older methods of extending the efficiency of gasoline. Previously, the cost of these additive materials were too high to compete with cheap gas, but now it's becoming our only option.

As baffling as it may sound, the way our cars use gasoline right now, only around 25% is actually used for the vehicle's movement and accessories. The rest escapes through the exhaust pipe. So researchers at Ohio State University and Caltech are working on ways to develop a thermoelectric material that is twice as effective as current materials. They say the ideal usage for this is in automotive engines, as the heat created inside is perfect for this application. The downside (yes, there's always a downside) is that the materials used now as highly toxic, so an alternative is being researched.
