Stirling Biopower (formerly ST !ower" ma#es

Stirling$cycle external combustion engines thatconvert heat from a variety of sources into electricityfor commercial, industrial, and renewable energy

mar#ets. The company%s !ower&nit uses heat from

sources such as li'uid fuels, landfill and digester gas,petroleum flare gas, and other low$grade waste fuels.

The technology was originally developed in the early)th century and later eclipsed by development of the

internal combustion engine, which now powers mostmotor vehicles. ST !ower was established in )*)

and revived as a business venture in ))+. Thecompany shut down in early ++* and was revivedagain under new ownership in mid$++* as Stirling

Biopower.
