SUBSTANCE: method for power generation uses a membrane operated due to pressure waves and rarefaction of air which occur during motion of transport vehicles. Oscillations of the membrane actuate an electric power generator that generates impulse alternating current. At the generator output alternating current is converted into direct current by means of a rectifier and then it is supplied to an accumulator (energy storage). Further the converter converts direct current into alternating one. In order to boost up voltage up to the required level a transformer is used; from its secondary winding voltage is supplied to respective loads.

EFFECT: improving reliability and increasing efficiency of conversion of air motion energy that occurs during motion of transport vehicles.
