RE: Tiny Long Lived Diesel Engine?
The concept of a generator on an engine is simple and everyone understands. The execution of the control system and how the energy will be used or stored is the real issue at hand. Are you going to sit next to it with your finger on the throttle? Are you going to design and build a power management and regulation system?
Those live diesels are cool, but I would go a completely different route for the same effect. All of those installations are about 10 times as large as needed and efficiency of those setups makes me shudder.
