Reply to comment by ledow 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

and a 15x20 cm solar panel can do 6 watts with 20% efficiency cells. 20x more powerful than this original articles "device" lol. these breakthrough stories are getting worse by the year

not true, 290 microwatts is useless. 15x20cm isn't even small. a 15x20cm solar panel would be able to do around 6 watts. (assuming 20% efficiency cells). an equivalent area solar panel would be 20,000x more powerful. which is why this is article is pointless

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
