The Army's solar array at Fort Carson, Colo., is part of the Army's largest microgrid installation. The array is a 2 MW system that covers 12 acres and produces 3,200 MWh of energy annually, and is part of an overall strategy by the Army to use solar power to cut costs and for other tactical purposes.

Thank you, bobjengr. When reporting these stories I don't always get to hear real-world perspective and it's really good to hear about your friend's grandson and to know that these inventions are relieving the burden for soldiers, and actually working well.
Actually, @shehan, the point of the solar chargers is that they reduce the weight soldiers carry. They need less batteries this weigh. They themselves I don't think are very heavy--less than the weight of all the batteries a solider would carry anyway.
The reality was that generating power from noise was not at all efficient, and probably could not ever be useful. It was presented as an interesting thing that somebody discovered.
And in another area you will find that officers DO NOT carry artillary shells, and probaly never carry amunition for other than their own use. There are a few exceptions, of course, but not very many of them. There are a whole lot more folks in the infantry and the support parts of the service who do that hard and dirty stuff.
And how far could you sprint with a hundred pounds or so on your back? In the thick of combat those burdens can be quite a handicap. It can be done when the stress level is high enough, but it burns one's energy just the same. So sometimes a lot of stuff does wind up being left behind.
The solar power system is a good idea but it may not be a good choice for those in the thick of the action.
I think that I may have rambled a bit in that third paragraph. Sorry about that.
@pubudu – yes not every camp can use this as a power source, some of them face winter where the sun light might not be sufficient for charging. In such situations the solar chargers would not help much.
@shehan, Well, that's a good question. I saw the report on Bloomberg business news awhile back. It's one of those shows they run on weekends and holidays when the markets are not open. They showed other methods that Israel uses to reduce dependence upon oil.
On Memorial Day, Americans remember the sacrifices the US armed forces have made, and continue to make, in service to the country. All of us should also consider the developments in technological capabilities and equipment over the years that contribute to the success of our military operations.
