I admit I have a little green in me. I drive a Prius, use CFL's, practice the three R's, rechargeable batteries, etc. Mostly to save some money and not in any 'real' desire to stop bathing and hug trees.
Since we do use lots of re-chargeables of various sizes, I picked up a universal charger. The other day I was digging through my den closet and came across some solar panels I had bought at a Radio Shack clearance sale awhile ago.
I looked at the panels.
Looked at the charger.
Looked at the panels.
Looked at the window w/ the sun shining through.
And the lightbulb came on.
Not as fast as the plug in but a trickle charge is better and it will save a few more pennies each month. And when the Zombie Apocalypse comes and the power grid fails, I'll still be able to use my flashlights.
