Abstract
We develop a concept, calculate an efficiency and made a model of new devise for converting heat into electricity. The work of our devise is based on the reversible reaction H2SO4+nH2O=H2SO4*nH2O+Q. The work of suggested devise consists of two stages: distillation of sulfuric acid solution in temperature gradient and generating electrical energy in galvanic cell. Calculation shows, that the efficiency of this way of heat converting to electricity could be 4,5% if the temperature of if T1=313 K (40 C) and T2=293 K (20C). Increasing T1 up to 373K we can increase the efficiency of the devise up to 12-14%. The model of this devise is consist of two blocks: distillation block and block of concentration cells.

Keywords: chemical thermocouple, geothermal energy, low-potential heat energy, thermogalvanic cell
