In this paper, the recent developments of the CDE (Concentration Difference Energy) system and engine are reported.
This system offers a kind of general methods of energy conversion, storage and utilization of thermal and mechanical energy of alternative resources as solar, oceanic heat and wind power using cyclic change of concentration of solvent in any solutions, which is one of a thereto chemical energy conversion phenomena.
The aqueous solution of mixture of CaCl
2 and LiCl is selected here as the most suitable solution, and nickel cupper alloy is selected to be the best anti-corrosive material against the above solution.
A manned try-wheel CDE car is driven for more than 15 minutes, and 1kw CDE engine is experimented successfully.
Many proposals of future application of this CDE system including power recovery from industrial waste heat and power generation from salinity gradient energy resouces are also proposed.
