It seems even the U. S. Army eco tip. That green technologies were also entering the army tents stars and stripes we had noticed for some months, but a few days ago, the army tents News Service, the organ of official communication from the U. S. Army, announced that the upper floors is currently considering whether to upgrade the equipment of the soldiers, making them less energy and impact. In particular, we discuss a "multitude of army tents with flexible solar panels, portable and lightweight," to eliminate the heavy dependence on electricity generators and, consequently, the transport of fossil fuels to power them. [Tents] are ideal for charging batteries, computers, night vision, and to secure communications in general - said Katherine Hammack, Army secretary for installations, energy and development - Do not want a generator on a mountain top, and do not want to have to carry fuel to a generator or drag various batteries. In this regard, the soldiers on duty in Afghanistan have already experienced the benefits of a sustainable budget, since a year now have some innovative ecofriendly instruments. Specifically, the "Temper Fly" is a tent of 16 x 20 feet, capable of generating 800 watts of electricity, the "Quadrant" is instead a smaller version of the Temper Fly, able to generate about one quarter of the corresponding watts (200), and finally, the Shades Power is the largest of the three, and generates some 3 kW / h of energy. Steven Tucker, an engineer in the Natick Soldier Research Design and Engineering Center, comments on the latest arrival: alternative energy scenarios are really to shine in the missions where you do not want to use a generator because they do not want the efforts and the resulting burns, or where the replacement of the power source with the fuel would not make sense. . . Fortunately or unfortunately it is too early to prepare for camping. The U. S. military, however, needs army tents for operational purposes and to organize with computers, instruments and communication presizione. Usually this kind of camps are powered by gasoline generators. The Army secretary Katherine Hammack, however, announced that testing of the household are in place on the tents can extract energy from the sun. With solar panels, in fact, the sheets can generate power from 200 to 3000 watts. If you're referring to photovoltaic home you're saying a great millstone. a good system for domestic or 3 kilowatt you pay much less than € 20,000 in some years are fully amortized by the savings of electricity and from that sold to ENEL in times of inactivity. If you do not like to spend the money for the installation you can safely make the fund from the bank, which will return the proceeds of your loan by taking all the energy not used by your house and you sell ENEL, in this way do not spend a penny but stops paying the bill. This is not "free" as you say?. Yes, the problem is that you forget to pay you Enel very easily, otherwise the problem would be resolved, inter alia, to grande. E Enel makes money from this system, each kW photovoltaic sold by Enel to buy the release from a kW oil equivalent and / or coal abroad.
