Energy saving idea?

Hah got this solar powered torch from IKEA. My fren bought this some time ago at $19 and it's on sale for $9!

I was thinking that it could be useful and could impress my dad. It's bright enough to do reading in my room. Could save me the nagging from my mum of falling asleep with the lights on and with less guilt of wasting electricity.

Daddy wants to buy another 3. -_-"

For a moment, i thought that this could be a great gift for those needy families, who sometimes have electricity cut off cuz they din pay their bills. good enough to light up a small room. not bright - but at least u can move around.
