Over several years, I've neglected to keep my stainless steel bright and shiny. When I dive into cleaning the deck hardware...I've got a long hard slog to get back to ship-shape.

news item: Solar-powered desalination device wins MIT $100K competition

"Nona Desalination is developing a compact water-desalination device that requires less electricity than a cell phone charger."
"The traditional approach for water desalination relies on a power-intensive process called reverse osmosis. In contrast, Nona uses a technology developed in MIT’s Research Laboratory of Electronics that removes salt and bacteria from seawater using an electrical current."
“Because we can do all this at super low pressure, we don’t need the high-pressure pump [used in reverse osmosis], so we don’t need a lot of electricity,” says Crawford, who co-founded the company with MIT Research Scientist Junghyo Yoon. “Our device runs on less power than a cell phone charger.”
"The company plans to sell its first units to sailors before moving into the emergency preparedness space in the U.S"
