Reply to comment by skedeebs 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

> harvesting water from ambient humidity

It is called a dehumidifier and uas been around as long the fridge and AC. All the kickstarter projects promising water from air are scam. It is cheaper and faster to truck water to the places that need it. Dry places won't produce any water from air. Humid places have water already amd dehumidifying it from air is expensive, your solar cell will get you a cup of water per day.
