Is the rotary engine dead?
No. While Mazda discontinued RX-7 production, the RX-8 is now the current Mazda rotary powered vehicle, and continues development efforts along several threads, including alternative fuels, such as hydrogen. Rotary engines are produced by other companies for use in marine applications, model and experimental aircraft, and various stationary power applications. See links to car stuff for links to a few. Conversion packages are also available for using Mazda rotaries to power light aircraft.
