  • the working substance generates work in the "working body" of the heat engine while transferring heat to the colder "sink” until it reaches a low temperature state. During this process some of the thermal energy is converted into work by exploiting the properties of the working substance.
  • the working substance can be any system with a non-zero heat capacity, but it usually is a gas or liquid.
  • An advantage of using metal fuel is that the burning thereof offers a high energy output per unit fuel; either measured as per weight or per volume. Due to the relatively high density of metal compared with conventional fuels, the advantage of burning metal will often be largest when comparing energy output per unit volume. Another advantage is that the combustion does not produce greenhouse gasses and thereby is more environmentally friendly than a number of other energy sources, in particular fossil fuels. Furthermore, huge amounts of metal scrap are produced in the machining industry, and the present invention provides for an efficient use of this scrap.
