Really? We have a Hydro Powered Calculator now? Holy hydrogen! A single oxygen atom bonded with two hydrogen atoms equals my favorite drink, or so I think thats how it works. So yeah, this thing is too cool for school or work, you just fill up the three water powered batteries, plug them in and youre good to go!
The water-powered batteries consists of two electrodes made of special alloys, which, when immersed in water, produce electricity through a chemical reaction. Simply refill the battery as the water evaporates, typically every two to three months. Not only is this eco-friendly, its providing free energy. Well, not enough free energy to power your computer or drive you home, but its still impressive!
Our Hydro Powered Calculator is made of clear plastic with geek-chic green buttons so you can see the system board and the process as its happening!
Measures 2 inches tall x 5.25 inches long x 3 inches wide.
