Water-Powered Calculator

Water-Powered Calculator

Remember that Water-Powered Clock that we wrote about last week? Now you can get a calculator powered using the same kind of environmentally friendly technology.

Add a few drops of water to the removable battery and insert it in the calculator for up to three months of use. When the display begins to fade, just refill the battery.

Features:

  • Eco-friendly new battery can be re-energized by addition of water again and again
  • Battery can be stored in a dry state indefinitely, and activated when needed
  • Ergonomic design
  • Rectangle shape
  • Large LCD display
  • 12-digit display for home, school or professional use
  • Large easy to use buttons
  • Buttons measure approx 3/8-inch square
  • Includes standard adding machine functions such as memory + or -, last digit correction, rounding, automatic decimal, etc.
  • Two non-slip feet on bottom of calculator

The H2O Desk Calculator is yours for $24.95 from the Solutions website.

    Man, this is cool! So slowly water can be a power source of electronic devices! Really can’t imagine what the future will be if water is the source of energy! :D

    ….What’s wrong with the solar/light power calculators?

    There’s nothing wrong at all with those, Norumu. They’re great products! But thee’s nothing wrong with having a few alternatives to choose from either.

    Thanks for your comments folks!

    Was thinking that too Norumu, but what if you needed a calculator underground or elsewhere without a sufficient light source?

    That’s true Yanto, a solar calculator would probably be better in Sahara. :)

    Thanks for stopping by!
