If you're like me, you've got a bunch of things hooked up to your PC that are only used when the PC is on. Unfortunately, so long as electronic devices are plugged in, they're almost always drawing a small current. With this USB power supply I'm about to link to, when your PC is off, it will totally switch off power to peripherals. For me that could mean my printer, dual-monitors, computer speakers, external hard drive, and cable modem.
Perhaps someone should make something to make use of energy we have on us. We all gather static electricity, instead of letting it zap us, let's use it!
