You can’t squeeze blood from a stone, but wringing water from the desert sky is now possible, thanks to a new spongelike device that uses sunlight to suck water vapor from air, even in low humidity.
This would be much better than an electro chemical battery … as long as the phones we power with it don’t microwave us to death…
…beyond just touchscreen gadgets, the researchers say the thin, flexible device could also be used in our clothing or shoes, helping us harvest energy from our body movements potentially all day long.
- Researchers have previously tried to create fibres to supply energy
- But many of these couldn’t withstand clothing manufacturing
- The new material incorporates two types of fibre with cotton, creating a flexible material that is fully charged by sunlight
…three technologies – solar, batteries and electric vehicles (EVs) – are poised to disrupt a $6 trillion energy industry over the next two decades.
