Having studied Material Science in college, the latest issue of The Economist made for some interesting reading. Specifically the article about combustion engines made out of nickel alloy. Since nickel has a higher heat tolerance than steel as a powertrain it could work. What i have a problem with is how do you get the electronics apparatus to function without constant shorts?
