The internal combustion engine (ICE) has had a remarkably successful century and a half. Unfortunately, it’s notoriously inefficient, wasting anywhere from 30 to 99 percent of the energy it produces and spewing unburned fuel into the air. Last week, Gizmag interviewed Dr. Alexander Shkolnik, President and CEO of LiquidPiston,

Studies are underway at the U.S. Army Research Laboratory, or ARL, to create a ‘super engine’ that could allow military ground vehicles, stationary power generators, and small unmanned aircraft, for example, to operate with the same kind of fuel. In the late 1980s, the DOD issued its “Single Fuel
