Recharge your light while caving...

Researchers at Simon Frasier University in British Columbia have developed technology that generates electricity from the natural motion of walking. In an article published in the journal Science this month, Max Donelan, an assistant professor of kinesiology, and other team members say their biomechanical energy harvester promises to revolutionize the way people charge the batteries that power all sorts of mobile gear.

Their harvester, which straps across a knee joint just like an athletic knee brace, can generate up to five watts of electricity with little physical effort. And one minute of brisk walking can generate 13 watts -- enough to support 30 minutes of cell-phone use.

Across the knee? It better be made of some indestructible alien material. I wish my knees were.

According to what I read, the product is not commercially available yet. I think it is a great idea, but it probably wouldn't hold up to caving.

It does not look ready for caving just yet...

Speaking of not quite ready for caving....

What ever happened to those several people who posted up here about how they were going to invent some new caving gadget that will be better than sliced bread? I seem to recall Cavechatians giving him/them a hard time about having an odd approach--like a solution in search of a problem--but they defended themselves admirably. I want to know how they were right and we were wrong and caving will sudden be so much better!
