Diesel tankers clearly have their vulnerabilities... But that PV farm would be impossible to miss with mortars and not that hard to hit with the kinds of rockets popular at the eastern end of the Mediterranean. That's a pretty big perimeter to patrol, too. Maybe it's good for an installation deep in the US with a single power feed... Maybe it'll work long enough to recoup the investment. It's definitely good for shovel-ready companies.

As far as "lightening the soldiers' load" goes? Assuming the battery weight vs. charger weight threshold has been crossed, and the logistics of dealing with worn out rechargables has been resolved, it would be more accurate to say that the percentage of weight in batteries is reduced. The soldier will carry all of the weight a soldier is capable of carrying. Any battery saved just makes room for more ammo or water.

For the military, i have heard that adopting solar is more than financial or other benefits (significant though they may be) - it is a matter of national security. I heard a story some months ago about a military base in Nevada. The commander added solar PV to the base when he realized that his entire base was dependent on electricity supplied to him on a single, miles-long line through the desert, and that his base could be brought completely down if that power were cut by terrorism or an outage or just maintenance on the line. You can imagine, it's even worse in overseas bases. Just like reducing the weight (and bulk) that soldiers have to carry, it's all related to operational readiness and the ability to do their jobs no matter the circumstances.

far911, I agree with you, and actually there are a few things like this that are becoming available for consumers. I am not sure about solar harvesters but I have written about energy-harvesting clothing that people can wear that can help charge things when they are not near electrical outlets.

You mention hiking, and actually a story I wrote about a company that has invented energy-harvesting insoles for hiking shoes: http://www.designnews.com/author.asp?section_id=1386&doc_id=267997

This could provide the type of charging you're talking about.

Yes, Lou, it's interesting how solar is becoming a way the Army can achieve other goals, making the military an investor in green energy without the energy aspect of it being the most important part of the equation, if you understand what I mean. So by using an alternative energy source, they are making soldiers more mobile and achieving some of their own goals.

Solar power contract
far911   2/25/2014 4:07:04 AM

The Army Corps of Engineers and Energy Initiatives Task Force announced 15 contracts for military solar power, which is pretty impressive, but that was a preliminary step involving the formation of a pool of eligible bidders for future projects.



One of those 15 winning Army contracts went to Chevron Energy Solutions, which is also part of the public-private partnership that went into building the new solar power plant at Davis-Monthan AFB.


So companies with good repute and expert performance is gaining quite a revenue.

You are right about US airforce.

It looks like the Air Force wins  in terms of military renewable energy projects. The biggest military solar power plant in the US has just been completed at Davis-Monthan Air Force Base in Arizona, a 16.4 megawatt installation that is expected to save about $500,000 in electricity costs yearly and provide about 35 percent of the base's electricity needs.

Portable solar based charger is also a great invention and means of convenience , not only for soldiers but also for any consumer who travels rather do hiking.

Effciency with minimum running cost

It great that at a far off area solar power is providing 19000 personnels with basic energy need.Producing 3200 MWh at one place encourages other to do so at other areas by minimising dependency on external sources and increases the effeciency.

This is a great installation for locales where the grid is questionable (i.e., Afganistan) and in desert areas that get a lot of cloudless days.

All branches of the military are moving forward with solar power.  The Air Force has panels like this on a base in Nevada.

I forget which branch is looking into flexible panels embedded in uniforms to generate power in the field.

Good stuff!
