Pyscho-Active, a project working to win the Automotive X-Prize has designed another version of the rotary engine, similar to the EngineAir design discussed earlier this week. The difference is that this is a mixed fuel vehicle combining combustion with pneumatic assist to boost fuel efficiency to greater than 100mpg. In addition to the engine breakthrough, the team has also focused on safety features to make this a safe vehicle to go alone with its efficiency.

There are no plans for commercialization at this point, but should the project win the X-Prize, we believe that will change.
