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.

Perhaps you didn't know that there are a variety of classes, both live and archived, offered via the Design News Continuing Education Center (CEC) sponsored by Digi-Key? The best part – they are free!
The complexity of diesel engines means optimizing their performance requires a large amount of experimentation. Computational fluid dynamics (CFD) is a very useful and intuitive tool in this, and cold flow analysis using CFD is an ideal approach to study the flow characteristics without going into the details of chemical reactions occurring during the combustion.

Programmable logic has come a long way from the simple devices we started out with. Remember Programmable Array Logic, or PALs? But where will we be in the next five to 10 years?
As industrial applications increasingly use process control systems utilizing sensor feedbacks to monitor various operating parameters, energy sources and consumption are becoming major factors of a system.
