control systems, efficient ducted fan designs, thrust vectoring mechanisms and aerodynamically stable composite airframe structures. The single most significant spin-off technology is the Rotapower engine, a Wankel rotary engine. This engine is now produced and marketed by Freedom Motors.

Their purpose is to develop and put into use personal transport vehicles that are as safe, efficient, affordable, and easy-to-use as automobiles. These would not be constrained by existing transportation networks, and will provide quick and convenient transport to any destination better than any alternative.

This vehicle should have a low environmental impact in terms of noise, emissions, and fuel consumption. Total costs of ownership over the life of the vehicle, including purchase price, operating costs and infrastructure costs should be reasonably low. This would be competing with such alternatives as personal or mass transport vehicles, general aviation, commercial air travel, and rail or motor vehicles.
