Useful USB Devices

A USB charger that is a Perpetual Motion Machine of the First Kind

And just as useful, a USB Pet Rock.

An evil voice in my head keeps whispering to me that I should set up a local franchise for selling these.

This reminds me of the Airnergy cell phone chargers that would presumably run off of Wi-Fi RF signals.

The question they ask, "Is it real or not", is a good one.

Dave Jones out of Sidney, I think has the best answer, though he takes a convoluted path to get there.

In the end, it's all great fun. I'll have to confess I never heard of the USB prt rock. Just when I thought I'd seen USB powered everything.
