Last night I had a drink with my friend and short after he started talking about self charging keyboard. It is a wireless keyboard and it "could" be charged when you are typing ( mechanical to electrical ) or by cleaning it ( whipping off the keyboard with something and then electrons "would" be stored somewhere). I think this is fairly funny but that can be good brain teaser... So what do you guys think? I know that this was caused by "few" drinks but still... I would love it if someone could debunk this.
