It looks like the machines that built the Matrix were right. You can use humans as an unlimited power source. At least this little light bulb does.
The nifty little bulb is powered by the static electricity that we generate when we rub against other things (I mean objects like a woolen sweater or a comb. Don’t get any other ideas).
I’m sure Aladdin holds the patent for it and will be taking them to court soon enough, so should buy it while you can.
