Water Powered Calculator

This is one of the craftiest gadgets I have seen in a long time, a calculator that is power by a few drops of water, 3 drops for 3 months of power to be exact.

Just think of the 10′s of millions of calculators sold or given away each year. Now imagine the batteries that are lying in landfills from those 10′s of millions of calculators, if everyone had an H2O powered calculator you could easily wipe that environmental impact out.

So what are you waiting for? You can pick up your very own H2O calculator for only $24.95 from solutions.com
