Here is a clock that you can bank on by using the water for energy. Shaped like an average soda can, you just add water to the body of the can and you can enjoy free energy to clearly see the time. You can add water when required but it typically needs checking every 6 to 12 months. Among its features include a high contrast display housed in a stylish transparent can. It is available in red, blue, green and gray colors.
Price: £9.99
