Star Rotor Engine

source: http://sustainabledesignupdate.com/?p=71

It seems every few months I read about another newer and better internal combustion engine in development. Having reviewed dozens of engines, all purporting to save energy and lower emissions, I find very few have a real chance of ever getting off of the drafting board and into our cars. Not so with the Star Rotor. This engine, in development at Texas A&M, has a real chance of getting to market. Testing is ongoing on the compressor section, which shows an 82% efficiency, and soon the expander will be similarly tested.

The Star Rotor is another invention from Dr. Mark Holtzapple whom I have previously posted for his work on developing biofuels.
