So, I must admit, this was really tough challenge for me. But some days ago I went to school and was talking to a friend about enrgy saving and a way to power something I use every day. He knows that I watch TV a lot so he told me about a remote control that is powered by a crank that you spin in order to provide it with energy.
According to the producer, 30 rotations are enough to power this thing for a week. So I went online and found this new battery free remote control.
Its not really cheap (22 €), but you dont have to buy batteries every time, its better for our environment and a little bit of a workout, not really :-).
I know the mission was to design something new to power it, but I am really unable to do technical stuff with my hands and was thinking of ways to design it, but failed at practical challenge.
But hey, better to do it that way than dont just sitting around and doing nothing!
