A TECS (thermal energy conversion system) which uses a Tesla turbine hooked up to a firebox. The Tesla turbine was based on the Tesla turbine made by Granett Engineering. The firebox contains a concept modification. The modification would increase efficiency, at the cost of only allowing non-polluting gases (which otherwise would cause the boiler tubes to clog). An example of a gas which could be used is nitrous oxide. The model also contains a spiral pump (with manual operation).
