OMG ppl its an video learning tool for kids. it explains where power comes from, who care if they use a 100 w buld to power a .2 w LED, it was to show (here the big part) KIDs how they work. they are nothing more then models

Thats fun.

Spot a lamp with 100 watts again a solarpanel, and that produces enough to power up a LED..
