Engineers at MIT and in China are aiming to turn seawater into drinking water with a completely passive device that is inspired by the ocean, and powered by the sun.
In a paper appearing today in the journal Joule, the team outlines the design for a new solar desalination system that takes in saltwater and heats it with natural sunlight.
The researchers estimate that if the system is scaled up to the size of a small suitcase, it could produce about 4 to 6 liters of drinking water per hour and last several years before requiring replacement parts. At this scale and performance, the system could produce drinking water at a rate and price that is cheaper than tap water.
Without the motivation to make a profit, few entities are both willing and able to engage in the considerable expense, risk, and effort required to spin up a mass production line.
I think “thirst” and “hunger” predate “profit” as a motive by several hundred million years.
Yeah, Neanderthals were famous for their efficient large-scale manufacturing capabilities
What a fantastic point. You can’t get a lion to chase a gazelle without a credit card these days.
when, all of human history must be like 250 years old…
