Personal Solar Desalination Plant
This is very exciting, and if it ever makes it to production, it is a must have for many survivalists.
Water is the most important thing to have in a SHTF-scenario – because without it we die.
Watch the TV series Alone to see how much effort people put into capturing water, even though they are right next to the sea. And consider scenarios like tsunamis, or where the regular inland water supply has been contaminated. Or, of course, if you are on a boat (because zombies can’t swim).
This device, hooked up to a cheap solar panel, can turn seawater into drinking water at a rate of 0.3 litres per hour.
No filters to replace!
The design means that you can scoop seawater into a container, instead of constantly moving with the tide. By doing so, that means if you refill a 7 litre container once per day, you can get 7 litres of drinking water in an adjacent container. That is enough for two people to survive. If your power source is only direct sunlight, with this model, you’ll need more solar power and a battery, to make enough drinking water for one person to survive on.
This also opens up the possibility of small-scale agriculture in dry lands next to the ocean, like a lot of Australia. Although the cost-efficiency would likely be very poor.
