My mechanical Stirling engines have a high electrical output of up to 300 watts, but they are very complex, require a great deal of maintenance and are therefore too expensive to use for the cost-effective generation of electricity in a micro-CHP unit.

By simplifying the design and, above all, consistently reducing the mass of the moving parts, I hope to make the engines simpler and more reliable; however, for the time being I am focusing primarily on the development of the thermoacoustic engine.
