Sometimes you guys have the least informative reviews. What is the range & accuracy like, how many squirts per fill and how much does each acid pack cost? (just like ink cartridges, they always get you on the squirting acid refills) #backpackspangolin
@spannu: I spent better half of this decade trying to erase this from my memory banks. Now, I will have to wait until 2014. Thanks. :) #backpackspangolin
@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.
@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.

And thankfully it's minus the whole acid shooting out if the anus part.. #backpackspangolin

Let's put it this way, it's easier and cheaper to buy a whole new anus than to buy refils. #backpackspangolin

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.
