Combustion engines, the engines in gas-powered cars, only use a quarter of the fuel's potential energy while the rest is lost as heat through exhaust. Now, a study demonstrates how to convert exhaust ...

Researchers from Skoltech have published a paper in the journal Physica D: Nonlinear Phenomena presenting an analysis of steady propagating combustion waves—from slow flames to supersonic detonation ...

We're not going to get into the whole "who made the first car" argument today. But there's not much doubt that the overall history of self-propelled vehicles goes back well beyond the Mercedes Patent ...
