Water Powered Alarm Clock
The name may sound familiar but this water powered alarm clock is a different one. This is one of those eco-friendly gadgets that doesn’t require a battery or power cord. All you need to do is “just add water”.
Apparently, the evaporation creates a constant supply of energy, using an electrochemical reaction between the electrodes and the water. Believe it or not, you only need to fill the Water Powered Alarm Clock once every three months for it to work. Looks like the “I forgot to pour water into my alarm clock” excuse will only work four times a year.
In addition to telling the time, the Water Powered Alarm Clock can also give you a temperature reading as well. I’m not really certain how the user sets it, but I’m guessing that there are some buttons on the back, or something.
Price: £19.99
