Doctors have told me that sugar really didn't make my boys hyped up. I've never bought that it didn't affect them--in fact, just ask any mom. The doctors weren't with the boys when they were bouncing off walls after a couple of sodas or candy. One, Dave, is now an adult and I think he's pretty much outgrown the problem. The other Nick, is an extremely energetic teenager that I still try to steer away from sugar.
Now, Sony tips bio battery powered by the electricity in sugar (I told you so Doc). See Sony tips bio battery powered by sugar. So far, the battery test cells are generating up to 50 milliwatts--enough juice to power music playback on a memory-type Walkman (or an average size teen).
The battery generates electricity with enzymes that break down carbohydrates (sugar). The bio battery could actually be a "green" device, because sugar is a naturally occurring energy source produced by plants through photosynthesis. To top it off, Sony made the battery casing of vegetable-based plastic.
Seems to be a good idea. I'm just going to have to make sure Nick doesn't pop one of these batteries in his mouth.
