Reply to comment by FartingBob 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 giuliomagnifico

Renewable sources that can't even charge a phone are hardly sources of energy. Not the ones that can power houses, cars, etc...

Not every source needs to a power a phone. They said in the headline about the target use case.

I thought I was commenting to another comment, but nonetheless generating and powering very low power devices was never an issue. Also, these low-power devices are not causing climate change and whatsoever. They are solving a problem that doesn't exist. A small, super-efficient wind generator might be useful in some rare cases, but it is not a game changer in any way, providing such little power.
