    This boots could generate the initial energy needed by this Hydrogen-Based Rotary Engine [slashdot.org], and with that the uptime of this IBM Linux clock [slashdot.org] would be astonishing (and with that kind of energy, imagine a Beowulf cluster of those!)!

Anyway, just to prove that I did actually read it, here's a relevant quote: "the prototype boot generates about half a watt of power".

    Nice idea, but far from usefull.

    The previous Slashdot article [slashdot.org] on this topic gives actual numbers: 0.0013 W when walking normally.

    This fluffy article gives no numbers on the performance, but with their menthod it should not come even close to being realistic. When you do the math it is theoretically possible to get resonable amount of power from your shoes, but the technology is still experimental.

    As one of the developers of an Open Hardware PDA [tudelft.nl] I can say that you can only do very litte computation for that and it would require an afternoon of walking to scrape enough energy together for a cell phone call.

        Because no technical details are available their is no way to know if this is the maximum power output during touchdown of the foot or the average power output during an average person walking at an average pace.

        My assumption is that the quoted 0.5 W is the delivered top power, not the average. This would be more in balance with existing technology. Otherwise they go directly for the next Nobel price for advancing current technology with a factor of 10,000 .

        As a guy who likes technology I hope they win the Noble price, but it is doubtfull.

    If I remember correctly, there was a panel at Summercon 99 where Decius presented the concept for shoes like these as part of a presentation on a peculiar type of bio-encryption. His idea involved sending a security key to various objects (like a doorknob) via low power electricity oscillations sent across the skin. He suggested using piezo-electric generators in shoes as a power source.

    His idea was to use this system of information transmission to enable data-rich handshakes (using connected HUDs) among other things.

  • Trevor Baylis, of Wind Up Radio fame, is also working on this kind of technology. The approaches are pretty standard, and are ALL dependent on new materials which combine the ability to generate a current from flexing motion with a long lived flexibility to withstand many 100,000s of flexes over a number of years - often of highly variable force (walking vs running for example).
    At the moment the energy that can be created from these is tiny, roughly analagous to the energy created in a self winding watch mechanism pound for pound.
    This is going nowhere fast.

    The good folks at the MIT Media Lab [mit.edu] (especially under the Things That Think [mit.edu] research program) have been researching such things for years.
    The July/August issue of IEEE Micro [computer.org] contains several articles on their work, including one on parasitic power [computer.org].
  • The wwearable computing crowd at MIT and University of Toronto have been working on this stuff for at least 3 years now. I remember seeing a prototype piezoelectric shoe generator at MIT in 1997. I believe the reasearch was done in the same lab as the PAN (personal Area Network) which allows data exchange through skin contact... AKA a handshake will transfer your business card to the other person's wearable computer.

    from what I read at the links this is either a product based on the MIt research or someone re-inventing the wheel.

  • There is only one problem with these boots. Most likely, only geeks would use something like this since regular people tend to be techno-phobes. Unless these shoes can charge a laptop battery on a trip to the soda machine, I don't think that most geeks (not all, just most) would walk around enough to charge anything :)

I think I've seen the Emperor zap Luke one too many times.
  • OK, here is an idea on how to "build" electric boots. I am giving it away free, to the public domain. Hell, it might already be patented, I don't know...

    Build a boot with a fairly rigid upper, or with a frame around the upper, in such a manner that there is a semi-flexible pivot and a fully flexible pivot around the ankle (in other words, make it flexible in the full range of motion of the ankle, but try to keep it mostly flexible in the "normal" direction of motion, in line with the rest of the leg.

    Around this pivot you would need a gear system, with maybe a ratchet and small flywheel system (like the baycomm radio), so that as the ankle flexes, the flywheel is spun at a high rate of speed. Perhaps even make it spring loaded, so that when standing still, or during mid-stride, the flywheel continues to run for a short while.

    Attach a small generator (one of those cheesy 3V motors would be perfect if made a bit more robust), and tap the power.

    Feasible? Sounds reasonable to me, though perhaps a little bulky - but I bet with good design, it could be slimmed down and made to work rather well...
  • There was an Italian soft-pron movie about 20 years ago that did the same sort of thing. Used special sensors placed under matresses, and generated power when the people in the bed, er, engaged in recreational activities.
