Water Powered Calculator – aquatically rechargeable bean counter


Water Powered Calculator. Lasts for a month on a refill of good old H20. $19.99.

 Just add water or any other electrolytic liquid into its fuel cell and the chemical reaction between its zinc anode and cathode produces an electrical current that will power this Water Calculator for a month before it needs another sip.
