FIELD: electricity.
SUBSTANCE: device by means of capacitance converts the temperature gradient energy. The device comprises a bar from any dielectric material with large change of linear sizes at change of external temperature, capacity plates one of which is fixed, and the second one is attached in mobile manner to one end of bar from dielectric material. The second end of this bar is rigidly fixed on the motionless base, the material with high relative dielectric permeability, for example, ferroelectric material, piezoelement installed in space between the motionless housing of the device and the end of the mobile dielectric material and which is rigidly fixed with them on both sides. Note that the piezoelement performs power supply functions.
EFFECT: absence of additional power consumption for primary charging of plates.
