This alarm clock runs off H2O, with a little help from the internal battery which they promise will last about two years. When it dies, you can further save the environment by recycling it, since it’s made of recycling-friendly parts. It’s also kind of fun to use since to change the function between alarm, clock, timer and temperature, you turn it to rest on another side.
I predict we’re a mere six months from my laptop being entirely powered by Lucozade.
