Reply to comment by Gwolfski in Scientists have developed a low-cost small device (15x20cm) that can harness energy from wind as gentle as a light breeze and store it as electricity. With wind at 2 m/s the device can produce 3 volts and generate power of up to 290 microwatts (sufficient to power a commercial sensor) by nimnlil

not even remotely close to possible unfortunately. 15x25 cm is not small. and yet this thing only puts out 290 millionths of a watt. a single normal AA battery can put out 2-3 watts peak power. 290 vs 2,000,000. it would take 2 years to charge a AA battery with this thing if that puts into perspective how minuscule the output is
