Wow!! A promising, totally new gasoline engine design

Thanks to wattsupwiththat.com

New gasoline engine design has 4x efficiency of pistons

This looks promising. It is basically a continuous combustion wave turbine. While not super powerful in this early design and not intended to replace a V-8 it can be brought to market for a hybrid vehicle application soon, according to the researcher. See the video below. While they’ve got a focus on CO2 for the usual reasons, I’ll take increased efficiency any day.

Researchers from Michigan State University have been awarded $2.5 million from the Department of Energy’s ARPA-E program to complete its prototype development of a new gasoline-fueled wave disc engine and electricity generator that promises to be five times more efficient than traditional auto engines in electricity production, 20% lighter, and 30% cheaper to manufacture.
