Aisa Mijeno, a young Filipino engineer and environmental advocate, has conceptualized a product that is not only environmentally friendly, but will provide basic lighting to the less-privileged: a lamp that runs on salt water!
Reminiscent of a hand-cranked bingo number generator, Poly Glu International of Osaka has developed an easy-to-use portable water purification system, Eco-Polyglu, intended for those cut off from access to clean potable water.
The mechanics of the system are simple: pour dirty water in need of cleaning into the 10-liter capacity tank, add a packet of polyglutamic acid, insert a filter, and use the hand crank to spin the tank for about one minute. Voila! You now have water that is safe to drink. Change the filter and you’re ready to go again. The system’s water tank can also be easily detached and carried like a bucket.
