US Army employing new Intelligent Micro-Grid as the technology proliferates

Intelligent Micro-Grid system technology developed for the US Army is finding its way to the private commercial sector, even as the army continues to guide further research and development enhancements.
Seeking to eliminate diesel generators, the army awarded Arista Power Inc - a startup manufacturer, designer, and integrator of renewable energy generation, management, and distribution systems - a nearly million-dollar development contract in January 2012 for phase one development of a new Intelligent Micro-Grid.
The system falls under the aegis of the Renewable Energy for Distributed Under-Supplied Command Environments programme, guided by the US Army Communications-Electronics Research, Development, and Engineering Center.
Arista Power delivered the initial Intelligent Micro-Grid to the army and demonstrated the system at the US Department of Defense (DoD) during the Pentagon's Energy Security Event in October 2012. The second phase, also a nearly million-dollar contract, was awarded to the company later that October and is intended to further develop the capacity, scalability, and energy behaviour management capabilities of the Intelligent Micro-Grid.
The programme includes options for additional funding for continued development beyond the second phase.
Now, Arista Power has received a fourth order for its new Mobile Renewable Power Station (MRPS) - which it developed for the army as a power source for its Intelligent Micro-Grid - from "a US government agency", the company said on 8 January.
An Arista Power spokeswoman said the agency that put in the order, which includes an extended support agreement, "has requested to not be identified". In its announcement the company said: "The system will be used to power communications equipment in a remote location where energy security and reliability is considered mission critical."
Mark Matthews, Arista Power's vice-president for sales and marketing, added: "Our system is a preferable alternative to using diesel generators in the field, and not only results in fuel savings for the US government, but also reduces the additional logistical cost required to provide fossil fuel to remote locations on a regular basis."
The new order is Arista Power's fourth MRPS, starting with the Federal Bureau of Investigation in June 2011 and the army in October 2011.
Arista Power's Renewable Power Station (RPS) and MRPS are powered by its WindTamer turbines, fuel cells, custom-designed solar energy systems, batteries, and gas generators. Its 'Power on Demand' system, also part of the Intelligent Micro-Grid, can use all of those energy inputs in conjunction with other smart monitoring technology.
The RPS is a containerised integrated, scalable, stationary system that can be drop-shipped to off-grid locations to be used as a micro-grid, while the MRPS is trailer-mounted and rugged enough to be transported to locations where off-grid power may be needed - including remote areas of the world, such as Afghanistan, where electricity may be unavailable or where there are severe power outages because of poor supply and inconsistent delivery.
With no emissions, the systems also eliminate the costly and often logistically difficult refuelling of diesel generators, a mission that has emerged as a deadly problem in Afghanistan.
"We are using some of the technology that we developed in phase one of the US Army contract on this new MRPS order, which is a goal for programmes such as these, to use the technology developed in US Army contract within other applications," explained Arista Power spokeswoman Cherrie Mahon. "We are currently working on phase two of the army contract that we were awarded and believe there will be additional follow-on phases to continue to develop the intelligent scalable micro-grid."
Matthews added: "We believe this contract demonstrates that Arista Power will be a leading partner for the Department of Defense as it moves to achieve these [energy] objectives utilising not only our engineering expertise in the development of the Intelligent Micro-Grid, but also our 'Power on Demand' peak-shaving system, our MRPS, our Man-Portable Micro Wind Turbines, and other products that deliver energy to remote locations with both renewable and traditional energy sources."
Uses of the systems are numerous, Arista Power and the army believe, and include off-grid applications such as remote locations, water pumping stations, telecommunications towers, oil and gas drilling sites, mining operations, border patrol, campsites, community centres at remote villages, disaster recovery operations, back-up for power blackouts and grid strain, remote communications towers, or battery charging stations at military bases.

Why States Still Use Barrel Bombs

Smoke ascends after a Syrian military helicopter allegedly dropped a barrel bomb over the city of Daraya on Jan. 31.(FADI DIRANI/AFP/Getty Images) Summary Barrel bombs are not especially effective weapons. They are often poorly constructed; they fail to detonate more often than other devices constructed for a similar purpose; and their lack of precision means they can have a disproportionate effect on civilian populations. However, combatants continue to use barrel bombs in conflicts, including in recent and ongoing conflicts in Africa and the Middle East, and they are ideally suited to the requirements of resource-poor states. Analysis Barrel bombs are improvised devices that contain explosive filling and shrapnel packed into a container, often in a cylindrical shape such as a barrel. The devices continue to be dropped on towns all over Syria . Indeed, there have been several documented cases of their use in Iraq over the past months, and residents of the city of Mosul, which was re

Russia Looks East for New Oil Markets

Click to Enlarge In the final years of the Soviet Union, Soviet leader Mikhail Gorbachev began orienting his foreign policy toward Asia in response to a rising Japan. Putin has also piloted a much-touted pivot to Asia, coinciding with renewed U.S. interest in the area. A good expression of intent was Russia's hosting of the Asia-Pacific Economic Cooperation summit in 2012 in Vladivostok, near Russia's borders with China and North Korea. Although its efforts in Asia have been limited by more direct interests in Russia's periphery and in Europe, Moscow recently has been able to look more to the east. Part of this renewed interest involves finding new export markets for Russian hydrocarbons. Russia's economy relies on energy exports, particularly crude oil and natural gas exported via pipeline to the West. However, Western Europe is diversifying its energy sources as new supplies come online out of a desire to reduce its dependence on Russian energy supplies . This has

LONDON POLICE INDIRECTLY ENCOURAGE CRIMINALS TO ATTACK RUSSIAN DIPLOMATIC PROPERTY

ILLUSTRATIVE IMAGE A few days ago an unknown perpetrator trespassed on the territory of the Russian Trade Delegation in London, causing damage to the property and the vehicles belonging to the trade delegation , Russian Foreign Ministry Spokeswoman Maria Zakharova said during the September 12 press briefing. The diplomat revealed the response by the London police was discouraging. Police told that the case does not have any prospects and is likely to be closed. This was made despite the fact that the British law enforcement was provided with video surveillance tapes and detailed information shedding light on the incident. By this byehavior, British law inforcements indirectly encourage criminals to continue attacks on Russian diplomatic property in the UK. Zakharova’s statement on “Trespassing on the Russian Trade Mission premises in London” ( source ): During our briefings, we have repeatedly discussed compliance with the Vienna Convention on Diplomatic Relations, specif
