regarding the remote control all you need is a beeper on it, that makes sound when you press a button on the TV, silly americans
also i would invent an car that runs on watter (not a boat), the engine would get the watter and remove the oxigen from the watter using aluminium bars producing Hydrogen, techinicaly a hydrogen powered car
ps: i know that all aluminum bars are covered in aluminium oxide but it can be dissolven by an substance whose name i have forgotten
so you can power the world using watter and alluminium
pss: also shouldt this be on the off topic session?
