We've seen water-powered clocks before, but the ingredients that power this eco-friendly clock from Bedol are just like a mix of tequila, triple sec and sour mix to make a mean margarita.

Bedol's clock is powered primarily by water, with salt and lemon juice being recommended for optimum performance. To replenish the power source, just add the aforementioned ingredients. While you're at it, why not make a cocktail for yourself?

Implications - The eco-friendly clock has no need for batteries. It works because the electrodes gain energy from the water that powers the clock. The innovative time keepers come in different bright colors such as blue, yellow and green.
