DIY Generator Types Explained
Understand alternator, engine-driven, pedal, wind and experimental generator concepts before choosing a project.
Editorial standard: Seller performance claims are treated as claims unless independently substantiated. Electrical and high-speed rotating equipment can be hazardous.
Mechanical generators
An alternator or generator converts mechanical input into electrical output. The mechanical input may come from an engine, turbine, wind rotor, pedal drive or another prime mover.
Storage is not generation
A flywheel can smooth or store mechanical energy, but it does not replace the need for an energy input.
Pick by purpose
An educational demonstrator, battery charger and household backup generator have very different output and safety requirements.
