Solar Water Solutions (SWS), a Finnish company, has just launched a solar-powered desalination system to turn seawater into fresh water for 400,000 rural Kenyans

Solar Water Solutions (SWS), a Finnish water technology company, has come as close as anyone to being able to offer the world essentially unlimited fresh water through its unique, zero-emissions, zero-running cost, and non-polluting desalination technology.

Now it’s being deployed, thanks to backing from the Dutch group Climate Fund Managers, in Kitui County, Kenya as part of a long-term goal to provide water for 400,000 rural Kenyans by 2023.

SWS has packed up their desalination plant into a shipping container, making it easy and efficient to ship 200 units to the shores of Kitui, where the technology will convert between 4,000 and 7,000 liters per hour from seawater, or 10,000 liters per hour from brackish water, powered entire by solar panels.

When Aptera debuted plans for their electric vehicle in 2007 the solar panels were only powerful enough for climate control, but now, 14 years later, Aptera’s 3-wheeled rig relies on just the sun for most of its charging needs.

To achieve this “never charge” status, they created a hyper-efficient vehicle and added 700 watts of solar power, capable of covering most commuting needs just on the solar, bringing the car’s range to 1,000 miles of autonomy on a full charge.

“It starts with a math equation,” explains Aptera co-founder Chris Anthony, “which means first aerodynamics, because what you don’t realize is that with a typical sedan you use 60% of your fuel just pushing air out of the way…”

“Then, if you couple it with an electric power train which gets much more power to the wheels versus an internal combustion engine, and then if you make it lightweight you decrease rolling resistance and other things and you end up with a math equation that is very, very efficient. And when you’re very efficient you can do things like put solar panels on your vehicle to charge your vehicle with a reasonable amount of range.”
