We are debating the benefits of a recharging backpack on technical grounds. Having a recharging system for peripheral electronics that is insufficient for the exo is probably a good alternative; however it begs the question of how much electricity is required to recharge peripherals. I am wondering if solar would be a good way to go. This blog is called DefenseTech for a reason. We are debating the benefits of a recharging backpack on technical grounds.

If the HULC allows ONE soldier to carry 200 lbs. of anything, even if it's only 20 klicks, that's called an improvement. SO, it really won't matter if the energy-harnessing backpack is 2 lbs. heavier than your average backpack. Think about it. These guys carry more than their fair share any day of the week, now they have the chance to get help to do it, easier and more efficiently. SO WHAT if the backpack can't charge the battery on the exo? If the backpack is any good, it could build up the charge necessary to field the ever-growing array of electronics equipment that soldier may have to carry. Can a soldier carry a normal backpack instead? Yeah, but it's just energy wasted. Can someone carry the "power-pak" and not wear the exo? Absolutely, but you could carry more, more easily, if you were wearing it. Please stop turning this blog into physics class. I hated physics class. Mostly because of the teacher. P.S. Lasers are cool. No, I think you all are missing the point. If the HULC allows ONE soldier to carry 200 lbs. of anything, even if it’s only 20 klicks, that’s called an improvement.

However, what this combination should do at the very least is extend the time before the exo power systems need full recharging. Depending on how efficient the overall combined design is, we're looking at maybe 10-20% longer battery life. It's essentially the same thing as regenerative braking for cars. What it comes down to is if the troops are willing to haul maybe several extra pounds for a longer battery life for the exo. Of course we'd then have to compare efficiencies between this system, more batteries, etc. As many people already pointed out, this won’t work the way the author intends.

But I think many of you have over looked the fact that there maybe a lot of tricks and tech that both these systems share. So maybe they wouldn't be bad bedfellows.

Just shoot the fat Nazi inside the exoskeleton, and the exoskeleton will keep running towards you, with the dead weight bouncing inside it... HA HA HA HA HA HA !!!!! I made a funny!!!

This is not the case for all batteries, but depending on the type of batteries, recharging while in use is not good for the battery. I will add links about power generating boots FYI.

Maybe you want to add it to your HULC combo meal. However, don't overestimate its potential. It may expand the operation time, and allow rechearge, but likely not enough to recharge to 100% during operation. You would probably consume more power than recharging. Meanwhile, Berkley UC building BLEEX does not enjoy battery power, and uses fuel instead, due to dead weight of a dead battery, and probably with an energy density of petroleum based energy compared to batteries.

Is it any wonder that 1/3 of Americans are defrauded every year. Save the money wasted on those programs and give those people a decent education.

It's not 100% efficient, you see. It will never make back all the energy it needs. Let's say it's super-efficient. We'll say that it creates one unit of energy for every two you put into it. That's really good. Now you're going to strap it to the exoskeleton. So if walking around for an hour in this exoskeleton normally uses 1000 units of energy, it's going to require more when you're wearing the backpack. So we'll say with the backpack on, you're using 1100 units of energy. Now, that extra 100 units of energy is going to be converted into 50 by your super-efficient backpack. This means that you're only burning 1050 units of energy in your hour long walk -- which is 50 more than what you started with. It's much more efficient to just carry more batteries. Theoretically, something like a solar cell could create more energy, because it's pulling in something from outside of the system. Will some of that energy come from the human? Yes. But that eliminates the entire reason to use an exoskeleton in the first place. The whole reason to have the exoskeleton is because we want to reduce the energy used by and the stresses on the soldier. The backpack would be wasteful. It’s not 100% efficient, you see.
