Dean Kamen has unveiled the latest iteration of his power and water package for the third world. The two components are a water purifier called Slingshot that uses a fraction of the power of alternatives and a Stirling engine based power generator that works on cow dung. The $1500 water purifier will produce 1000 liters of water a day, while the $3,700 generator produces around 1 kW, which is enough to deliver light to a small village. The two products have been in development for years, but it looks as though they are now ready for more prime time consideration.
It’s amazing that in this day and age, when investment bankers routinely take home $50 million paychecks, we can’t seem to work out how to help the majority of people on this planet from being at risk through lack of water and power. Astonishing. Here’s hoping things change sooner rather than later.
