Stirling Engine





=Overview= A Stirling Engine can operate quietly from any heat source to generate mechanical power (work). It operates by operates by cyclic compression and expansion of air or other gas, the working fluid, at different temperature levels such that there is a net conversion of heat energy to mechanical work. It can be coupled directly to a hydraulic transmission, although only a handful of projects have explored this possibility over the decades.

Heat sources include Solar Concentration power as well as biomass.

Applications and Product Ecology

 * In future versions of the GVCS, such a concept may be used for the Power Cube
 * can be coupled to water pumps for irrigation
 * biomass: heat can be derived from combustion or from pyrolysis, where biochar would be a useful, carbon-negative byproduct. With biomass-powered Stirling engine, one single engine could handle all sorts of different biomass, whether solid, liquid or gaseous. There is no need for tedious clean-up of fuel.
