Dean Kamen, inventor of the Segway, is aiming to tackle the problem of clean water across the globe. His Slingshot is billed as a low power system, but is hugely expensive to produce and needs a reliable supply of electricity to work. This is a huge global problem that will require several solutions. Michael Pritchard’s Lifesaver system takes an even simpler, self powered approach to the problem.
At least users of the Slingshot system will look less ridiculous than Segway users.
