Hybrid electric vehicles are often expensive and still use fossil fuels. Eventually there will be no choice but to turn away from fossil fuels in any case. Pure electric vehicles may leave you stranded if you try to go beyond their range. Increasing the battery capacity, also increases the weight, and power requirements. Most trips are still with one person per vehicle and in general we exercise too little and infrequently if at all. Grid

The Trinity Rotor Engine is a rotary engine that eliminates the problems of the Wankel and the power loss incurred by the piston engine while translating linear energy to rotation.
The engine consists of a perfect cylinder with a three point rotor similar to the Wankel. Each point of the rotor has a flat face that sweeps to a point perpendicular to the tangent of the next rotor point to create these faces.
The cylinder

This invention is suitable for any application that requires an internal combustion engine (ice)! Existing ice may be modified in such a way as to use the power of electromagnetic force to push the piston through its cycle instead of and exploding gas. By mounting an extremley powerful permanent magnet on top of the existing piston and positioning a very strong electromagnet in such a way that when the piston reaches top dead center, the
