Wonder if you could use the same idea on panniers on a motorcycle. That would be very helpful.

@RobinSure: Watch the video.....you should get a pretty decent idea of how it works. Pack is on a harness. Pack moves up and down within the harness. Up and down motion is converted into generating power.

That's the basics. The rest of the tech is voltage regulation, monitoring, hydraulics to reduce the impact of the up/down motion, lock-outs to stop the up/down, etc.

The movement generates enough electricity to power your gadgets, and the design actually relieves stress from the user.

Maybe I'm thinking about this incorrectly, but wouldn't the stress relief on the upswing be mitigated by the extra stress put on you on the downswing?

EDIT, aah I see how this works now. The video of that guy running is pretty wild. Looks good.

@Pope John Peeps II: It looks like it'd work great while he was running (keep the load from moving around too much, as it actually stays more stationary), but It just didn't look like it'd work that great while he was walking. As you said, the bottom of every one of those down swings will be felt by the Marine. It even looks like it bottoms out just after he steps, putting even more force down through his legs. I dunno, I'll take a normal pack, thanks.

Nope... try again. A typical cyclist directly driving a generator can crank out 150 watts for a few min, then passes out. No way passive walking will give 40 usable watts. Of course, he's probably got a couple mil grant and I don't.

@AlbertSulla: Obviously the 40 watts is generated when the bag is full. With a good 50 pounds of stuff to generate momentum, this could give 40 watts easily.

@AlbertSulla: I draw a different conclusion; obviously cyclists are weenies.

I heard his cousin Michael Kobe didn't do so well with his idea.
