At the heart of the technology are solar panels made from black metal that has been treated with femtosecond lasers. A femtosecond is an extraordinarily short unit of time, equal to one quadrillionth of a second. Pulses from these ultrafast lasers can precisely alter a material’s surface, creating microscopic structures that dramatically change how it interacts with light and water.
Neat
And it’s very easy to make, you just need to ask Finland to get black metal
Does anyone know what the drawback of a setup that distills the sea water and then air dries the brine. This always seemed like the easiest solution when I thought about it?
This is what will happen. We’ll use solar, or maybe someday fusion, to desalinate sea water. Then we’ll need to pipe it where it’s needed. We’re not going to run out of water long term, it will just be more expensive. Short term, yeah, there will be issues, and they could get bad.
We need to rein in capitalism and replace money with compassion as the driving motivation. I know it seems impossible, but it will happen one way or another. Either for billions of us, or for whoever is left after the apocalypse.
