Water Powered Alarm Clock

Here is the new eco-friendly alarm clock that is perfect for those who like green gadgets. The clock doesn’t need electricity or batteries. You just need to add water to power up your alarm clock and keep it topped up as the water evaporates for a constant supply of energy.

This alarm clock utilities an electrochemical reaction between the electrodes and water, which produces enough electrical energy to power it. This alarm clock also tells the room’s temperature. Once you have filled it, you should have at least three months power to go on before you need to top it up. If you are interested, you can purchase the water powered alarm clock for £19.99.
