Well, if you are the kind of person who do not care much about appearance, and you care more on the environment, then I have a solution for you.
Introducing .... Dynamo Remote Control, a battery-less remote control.
Steps to make one:
1) Buy or get a Hand Crank Dynamo that have a DC output.
2) Connect the DC output to your remote control battery compartment using 2 wires.
3) Every time you need to operate the remove control, just twist/crank the Dynamo handle and press any button on the remote as you would do normally.
It's that simple, really!!!
It may seems not much of a saving in terms of money, but over the long run, you avoided throwing away a lot of batteries, thus helping reduce the toxic waste on earth.
Mother earth is definitely worth saving, don't you agree? :)
The type of dynamo I am using, it has a Nokia charger DC output:
