One Step Closer To Becoming The Human Battery

from the neo?--is-that-you? dept

Well, one side effect of gasoline prices being so high these days is that it’s going to force people to start looking at alternative forms of generating energy. One area that’s often overlooked is how much energy is generated by the everyday actions of people. Sure, we’ve got those watches that charge themselves based on movement, but, that’s pretty minor (and who wears watches any more anyway?). So, some researchers are taking a similar concept and are trying to apply it to a backpack. The backpack is basically set on springs, and the energy of the pack shifting up and down is stored and can be used to power small electronics. So, for example, you could power your own mobile phone or mp3 player just by walking around (with a heavy backpack on your back). Of course, it was developed mainly for military uses, and it’s not like the average person is carrying around a backpack all the time anyway. However, as people keep buying more gadgets, maybe they’ll need a backpack to tote them around anyway — and if so, why not one that will power the gadgets at the same time?

Bum Rush Power

Couldn’t the kinetic energy of crowds walking into a subway station on a treadmill propel a subway train? Crowds at Asian train stations are sometimes known to create random tsunami effects, e.g. when the last train is about to leave, which causes a shockwave to go through crowds, breaking bones and flinging people high into the air.

Or you could drive through Michigan, where some street lights are twice as tall as normal and emit an ungodly amount of lumens, and it feels like a religious experience to have that thing shine down into your car.

This has popped up everywhere, but I still don’t get it. This backpack doesn’t produce energy, it just converts ‘wasted’ energy from walking with a backpack. The more energy you want from the backpack, the more energy the user needs to ‘waste’ making the backpack even more difficult to carry. It seems one could just design a backpack which ‘wastes’ less enabling the user to carry more weight. (part of which might be a hand cranked generator which would be even more efficient [weight/power] at generating electricity than this backpack!)

Re: No Free Lunch

its for people who are already carrying a backpack, right? so you’re carrying the stuff already, and walking for whatever reason – hiking, a soldier doing drills, whatever – why not harness that wasted energy to be used later?

is this idea about saving wasted energy comparable to hybrid cars recharging when you use the brakes? i’m honestly not up to date on this, so let me know if i’m saying anything incorrectly – but the cars didnt used to do that. but once they realized they could harness the energy that was being produced, they did it and it made it more efficient and better overall.

doesnt that same idea apply to this backpack stuff?

Re: Re: No Free Lunch

Rather than regenerative breaking, this is more like running the air conditioner compresser off of the drive train of a car. I think the point of the original post was that one could just as easily redesign the backpack to reduce the amount of wasted effort, this doesn’t apply to breaking where you must waste (or transfer) the energy to acheieve a goal.
