Solar engine
From Wikipedia, the free encyclopedia
A solar engine can be:
- a Crookes radiometer : A light mill composed of an airtight glass bulb containing a partial vacuum. Inside are a set of vanes which are mounted on a spindle. The vanes rotate when exposed to light.
- a Solar Engine circuit, a BEAM component which receives radiant energy, capacitates the energy, and then utilizes that energy in pulses for motor power or to power other circuits.
- a Stirling engine, a heat engine of the external combustion piston engine type whose heat-exchange process allows for near-ideal efficiency in conversion of heat into mechanical movement.
