Unscramble

Ive got this idea.
What if we could transfer energy. Yeah am not referring to electricity....
For instance, if my cell phone is running out of charge ... and i don't have access to charging it. What if I could just tap into a source of energy... like call up some number and the battery is charged.

Yeah i know thats far fetched and really stupid. But.. no harm in fantasizing rt?
lol

Why cant cell phones be charged using solar energy? Or, probably there r some around just that ive not heard of em yet. could be.
