We all are trying to do our bit for the environment and every little drop counts. This Wind Up Remote may not seem like a big thing for the moment but it does it bit by not using batteries. You just need to wind it up for use and the built-in mechanism powers it. Not much muscle power is required either; crank it up 30 or so times and you're good for the rest of the week. Samsung, Sony, Phillips, Panasonic either of these brands works with it.

The Wind-Up Remote Control is available from Gizoo for £19.95 or $39.
