I have always wanted to contribute something more to this world. To be honest, not necessarily to the people, but to the Earth, to the life it hosts.
The goal here is to make a working Low-temperature differential heat engine, that could be powered by sun-heated and Earth-cooled fluid. This energy potential is relatively low compared to the fossil fuels, but the heat flow between them is great and could be harvested for mechanical energy, if the appropriate machine is put in the flow.
Even though I want to stay humble, there is nothing humble about the goal I am trying to achieve here. But I do admit, that I need your help, dear visitor.
You decide, if the featured heat engine is worth your contribution. Whether you contribute your time, ideas, knowledge or even funding. Anything is welcome.
