FIELD: renewable energy source using wind and ambient temperature variations for generating electricity. SUBSTANCE: windmill has piezoelectric film blades such as made of polyvinylidene fluoride, braced together by means of heat-sensing members made of alloy possessing reversible transformation induced plasticity on spindles of fastening wheels fitted on common shaft and rotating under the action of wind. Piezoelectric film also emits electricity under the effect of ambient temperature variations, direct sun rays, film vibrations caused by wind when it alternately stretches and elongates producing additional electricity. EFFECT: improved design. 5 dwgw
