Electrochemical cycle for the conversion of the waste heat into electrical energy: the possibility of using in water transport

We developed a concept and calculated an efficiency of the electrochemical cycle of converting low-grade heat (temperature difference 10-80°C) into electricity. The cycle could be divided into two stages: creating a concentration difference by a solution distilled in a temperature gradient and electricity generation in concentration galvanic cell. The calculation shows that the efficiency of converting heat into electricity could reach 40-55% of Carnot efficiency in a temperature range of 0-100°C in the case of use of a multi-cascade distiller. The calculations show that ratio power/mass of the device is too low to be used in automobile or air transport, but it could be used in water transport.
