The boots have since been scrapped for the most part. The military is heavily investing in wireless energy transfer to power devices such as GPS, communications and optics with vehicles outfitted with power-transfer technology.

 

Also... looks like a lot of work.

I agree, Tim, especially now that we have so many gadgets that need continual recharging. I would imagine if this opened up, there would be a wide range of applications to charge devices. Perhaps one of those hand-grip exercise tools that build arm muscle while producing electricity.

Energy Boots or Powerd Exoskeleton

Last year I saw powered exoskeleton tests for the army.  The exoskeleton was a load-bearing means.  I suspect this might end up being more useful than energy boots.  Note how much the soldier's load weight has increased over time.  It's always going up.  A small weight savings in batteries will be erased by other, new, absolutely necessary equipment.

Energy harvesting boots

The picture reminds me of some boots that I once owned. I would like to see a race between somebody wearing them and an infantry-man weraing normal issue boots. Of course it is possible that they could run faster than I could while wearing safety boots.

Aside from that it does look like a potentially good idea.

Applying this in the battlefield can be a great application, but civilian uses of this technology are also high.  Imagine a running shoe with a similar technolgy that charges your Ipod or cell phone while you go running. This would be a geat way to stay green.

It is also interesting to note that many semiconductor device manufacturers have come out with specific energy harvester IC, like Linear Technologies LTC 3588. This segment will definitely gather momentum. Success stories like that of solar impluse http://www.solarimpulse.com/ will act as catalysts in energy harvesting.

You're right, Gusman, that's definitely coming. But assuming the foot generator doesn't impede movement -- or squeak too much -- it's quite a clever idea for helping the soldier to be self-sufficient out in the field.

Robotic soldiers--now that's a development I could get behind. Kind of like those soldiers/transformer-type robots that were part of the military crew in James Cameron's Avatar movie. Who cares if they get blown up. It's only money!!

Actually, the article describes the energy harvesting to be in the "heel-strike" portion of the gait cycle; so, the extra 100# would add about 50% to the moment about the ankle (assuming solidiers are less than 200#), making the 6-9W about 2-3% of the maximum ankle power.  We are collaborating on the opposite problem, providing power to the ankle for those with disabilities; and, this portion of the gait cycle will be harvested as well, though to a much smaller degree.

I suspect that this is just a step toward robotic solidiers anyway, for those instances where UAV's don't work.

The age of touch could soon come to an end. From smartphones and smartwatches, to home devices, to in-car infotainment systems, touch is no longer the primary user interface. Technology market leaders are driving a migration from touch to voice as a user interface.
Soft starter technology has become a way to mitigate startup stressors by moderating a motor’s voltage supply during the machine start-up phase, slowly ramping it up and effectively adjusting the machine’s load behavior to protect mechanical components.
Despite the astronomical benefits offered by 3D modeling, it is quite surprising that nearly 75% of the manufacturing industries still perform design operations using 2D CAD systems. What is the reason that keeps companies hesitant from adopting 3D technology?
Energy harvesting in particular seems to be moving at an accelerating pace. We now seem to be at a point where it is possible to run low-power systems primarily from energy harvesting sources. This is a big shift from even just a couple of years ago. Three key trends seem to have accelerated this dramatic shift.
ABI Research, a firm based in the UK that specializes in analyzing global connectivity and other emerging technologies, estimates there will be 40.9 billion active wirelessly interconnected “things” by 2020. The driving force is the usual suspect: the Internet of Things.
