This summer, frontline troops in Afghanistan will begin using two diesel-battery hybrid generators that could cut fuel use by 50 to 70 percent.
The diesel generators currently used at military camps waste a lot of energy because there's no way to store excess power that's being produced, but not used. The new hybrid generators, built by Virginia-based Earl Energy, will not only satisfy energy needs for the camps, but store energy in a bank of lithium-ion batteries.
The diesel generators run until the batteries are fully charged and then the generators shut off and the batteries provide the power instead. The new generators can provide the same amount of power from running for three to four hours as the old generators would by running 24 hours straight.
The new systems will each consist of an 18-kW diesel generator paired with a 40-kWh bank of batteries. The system also features a 10-kW solar PV system to cut fuel use even further.
What's even better is that from a cost perspective, the new systems aren't that much more expensive to buy, costing over $100,000 each, while the same size diesel generator would cost from $80,000 - $100,000. The systems are expected to pay for themselves in fuel savings within a year.

Cutting the US Army dependence to oil is most important as peak is either nearing fast or behind us.
Now, the USA as a country - and other nations as well - should slash their oil consumption too...

Currently a custom install of 10kw solar with 40kwh of lithium backup and no generator will cost a homeowner well over $100k. If the military can do a system that size (and with a windmill? See photo) we ought to be able to produce a system a third the size for a third the cost for the average house.

Aaron that type of sarcasm doesn't really help anyone. If you want to blame someone for the civilian deaths depending on your outlook you can either blame our politicians for ordering our troops to war based on lies or the terrorists who attacked us. While our troops shouldn't be randomly killing civilians any fool knows that ordering our troops to invade another country is going to kill civilians.

Sadly, I report to you, we trounced Iraq, on promise that our sacrifice would bring cheaper, and more readily available gasoline at the pumps in America. Guess who got screwed up the ass, who still owes on the national debt for this fiasco? Who will pay and his children will pay for this favor by George Bush to his Saudi friends? Still think this Corpocracy that stole our Democracy is set up for the American folks benefit? Still think that Capitalist is a nice word? Still think Corporatists have your good health in mind? Tell me now, why do South Koreans revolt, and refuse to eat American meats, cheeses, milk products? Why do Canadians refuse cheaper American cheese at their borders, advertise their own products as hormone, antibiotic free?
It is all well and good to laud the American Military for developing fuel saving generators, but the assumption implied, the propaganda here is the notion that they did this for 'green' reasons, and not for strategic reasons, and this type of Bull Shiite is intolerable, and has misled Americans into a plethora of falsehoods and left them mindless and numb souled. Please, do not tell me how to think. I will draw my own conclusions, arrive at my own notions. Tacit understandings, inferences, all part of the propagandists tools!

Our tents and wooden B-huts are not very well insulated. When it gets over 120 degrees outside we run the A/C as much as possible. It's great to use the sun for something other than draining our energy.

The problem is that this means all the generators are operating well below their most efficient load profile, which in turn produces two major issues: a) they don't run as efficiently thus wasting fuel and almost more important b) a diesel generator that is run inefficiently "wet stacks" which causes a huge increase in the amount of maintenance it requires. Huge.
The system shown here could, if/when hooked up properly, use the batteries as the rapid response peaking generator, thus taking an entire normal generator off line.
