Photovoltaic System Supplements Marines' Energy Needs
6/26/2012

The Naval Research Laboratory has developed a photovoltaic prototype for the Marine Corps. The system is fitted to a standard USMC-issue backpack and includes a 10.5-inch x 15.5-inch solar panel that can generate more than 11W under 1-sun air mass of 1.5 illumination. (Source: Naval Research Lab)

Woverholt, thanks for tracking down that info. That looks like very useful equipment to have on hand for power outages.

Sorry for the delay in responding. It has taken me a while to locate the company. The company I was contracting to at the time was Falcon Systems, but, that company is no longer in business.  The owner has started a new company called 1100Energy. The product you are looking for is SBP-1100e Smart Battery Power system. There web site is 1100energy.com.

Woverholt, I'd like to know the answer to Nadine's question, too. Is it available, and if so, where?

Yes, Chuck, I think this power source also beats the boot apparatus that generates electricity. That ultimately becomes a drag on walking. The solar collector may be the answer. So what to the soldiers do? Wear it on their back, or spread it out during lunch?

  It wouldn't make any worthwhile water with that amount of power.  Instead a manual pump unit would be used or just disinfecting filters/straws that gravity feed are more likely.

Even for electronics they better be eff, low drain as 55wthrs/day isn't much.

As I said last time a small 2lb wind or stream/river generator would make far more and for many more hrs/day. They could be the same unit with different rotors as we in the 1970's made to power our sailboat autopilots, etc.

One of these could power several soldiers needs.

 Nothing new here and available for campers, etc at well stocked outdoor sports stores or online.

200lbs of batteries?  Right!!   That is far worse than the 30lb claim in another recent article here. Just not true for a standard soldier outfiting.

Nor would this unit replace that much battery.  You can get 1kwhr in just 22lbs or less with lithium.  even less if they didn't have to be rechargable.  This unit would take 20 days to make that much power.

Woverholt- Can you give more details?  If your project went into production 7 years ago, is it still available to the public?

I was involved with a design that did this exact same thing and has gone into production 7 years ago.

Great development.  In addition to using electricity to operate electronic devices, I could see a soldier also using this to generate electrcity for a portable water purifier, which could further extend a soldier's range and duration.

I agree that it would be great to have this as a commercial item. It sure beats starting your car to charge your cell on a camping trip.
