Direct heat to electricity conversion
Research objective
    The objective is generator of electricity that is working as collector and transformator of heat energy of air (environmental).
Work
   Calculation, design, production and testing of generator should be produced by Proposer in three months period.
Methodology and technical approach
    The method is based on alternation of dielectrical permittivity in flat capacitor by means of rotation. The capacity and energy of the capacitor is depend of the permittivity, so if it is charging with inserted dielectric and it is discharging without dielectric member there is some difference in energy. This difference as additional electric power should be transformed from inner heat energy of moving dielectrical member that should be made of high permittivity material (epsilon about 2000).
Anticipated difficulties and recommended solutions
    Energy of capacitor is function of square of voltage, so it is necessary to develop high voltage design. From the other hand, the method include half-period of cycle when the capacitor have not dielectric and in this case it is just air gap capacitor. It is limitation for maximum operation voltage. Solution is optimal balance for air gap size and the voltage.
Expected end-product
    Power supply that is working as transformator of heat environmental energy in electricity.

Preliminary calculations
    Permittivity for good dielectrical material is about 2000. Let's take surface of plates S=1 (mExp2), distance between plates is 10 mm, voltage is 1000 V. Difference between energy of two-plates capacitor with dielectric member and energy of the same capacitor without dielectric member is about 0.88 J.  The generator can be produced as battery of 100 two-plates elements and in this case the energy difference is 88 J per one charge-discharge cycle. It means power 88 W per 1 sec rotation velocity. So, we'll can take about 8 KW if the velocity is 100 rotation per second.
