The flexibility of Parker’s technology and its use in racks, cabinets, and containers has been implemented in many other industrial markets where it has been easily configured to cool a variety of applications such as power electronics, motors, transformers, and batteries. The dual-phase liquid cooling process continuously cycles a refrigerant within a sealed, closed-loop system to cool a wide range of systems. The system uses a small pump to deliver just enough coolant to the evaporator – usually a series of one or more cold plates optimized to acquire the heat from the device(s). In so doing, the coolant begins to vaporize maintaining a cool uniform temperature on the surface of the device. The resulting two-phase coolant is then pumped to a heat exchanger where it rejects the heat to the ambient and condenses back into a liquid, completing the cycle.

By taking advantage of this two-phase evaporation process, system level cost savings are realized due to the use of smaller, lighter overall systems that are easier to maintain and run at lower, more reliable temperatures. Parker’s Precision-Cooled Rack Solution is an ideal product for wind turbines where the size and weight in the nacelle continues to grow with total capacity. In addition, the Parker precision-cooled rack is the only product available today that offers the potential to double the power density of key major subsystems such as the generator and power conversion system, and whose modular thermal management elements greatly simplify onsite maintenance when required, while reducing overall maintenance costs.

The compact and light rack solution leverage Parker’s long established and proprietary two-phase liquid cooling technology and rack systems, and offers a cost-effective alternative solution for applications in renewable energy markets, such as wind and solar.

Server Technology (News – Alert), a provider of data center power management solutions for over two decades, focuses on delivering this redundancy in its data center power and celebrates client success stories. One recent story highlighted the benefits experienced by one of the largest printers in North America.

This company was searching for a way to add redundancy to its critical single-corded devices after experiencing a number of power failures and costly downtime. As a result, the company was examining different Fail Safe Transfer Switches (FSTS) to determine the best solution for its environment.

There were two specific features that were at the top of their priority list, including the transfer of a power source from A to B or B to A, and the remote management of outlets. The company was concerned with data center power and knew that any solutions that met with their criteria would be better suited to meet their needs.

After evaluating different products and conducting their own testing, the company selected Server Technology’s FSTS solution. This solution stood out from the rest in that it offered the ability to add two temperature and humidity probes for environmental monitoring, and environmental conditions can be viewed through the network interface.

Server Technology also offered 16 outlet models, half of which are routinely powered by the A in-feed, and the other half are powered by the B in-feed. This redundancy ensures consistency in data center power for the customer. The “Fail-Safe” method also offers a number of advantages when compared with the standard automatic transfer switch (ATS) as it does not prohibit load balancing between the two supplied circuits.

The standard ATS will contain two in-feeds, yet will run all outlets from just one source. The secondary source is only used if an outage occurs. Data center power is protected and the result is less heat, less resistance and, consequently, less of a voltage drop as compared to the same load existing on just one source.

With the implementation of the Server Technology FSTSs, the customer has reported that he now has peace of mind in knowing that if power goes down his single corded devices will still remain up. At the same time, the client can now reboot devices that become unresponsive, while the environmental probes are providing the e-mail alerts and SNMP trap notifications necessary when conditions exceed defined thresholds.

With all of the catastrophic results that the recent tsunami caused in Japan, many people in multiple locations are working hard to get an emergency system in place, in case something like this happens again, the system could alert and inform people and potentially save lives. Voice broadcast technologies help these systems succeed and get a message out to a large amount of people in a very short amount of time.

In Seaside, Ore. a tsunami warning system will be tested today starting at 11:00 a.m. According to a recent article from KPTV.com, neighbors in the area will hear three beeps and a recorded voice broadcast that will say; “This is a test. This is a test of the emergency warning system. This is only a test.”

The message will be broadcast in both English and Spanish, and the test is scheduled to take a closer, more in-depth look at the system in order to determine if it will or will not be used as a way to let the public know about possible tsunami emergencies.

Although when hearing the term ‘voice broadcast’, many people might immediately think of political campaigns or advertisements, this technology can also be crucial in getting information out about places that can offer a safe shelter to disaster victims.

Voice broadcast technology can help not just in possible tsunami scenarios, but any type of potentially dangerous situation including tornadoes, hurricanes or road closures due to extreme flooding. Kim Kohatsu from Callfire, a provider of voice broadcast technology, pointed out in a recent blog that people who are looking for shelter, “likely don’t have regular access to the internet to read an email or check a website, but because they probably do have their cell phones by their side, CallFire’s Voice Broadcast is an effective way to relay critical information.”

If vehicles in London use Start/Stop technology, as much as 500,000 tonnes of carbon dioxide emissions can be saved each year, research from Bosch shows.

Its research shows significant carbon savings by using the system, which is becoming increasingly common in cars from a variety of manufacturers.

Indeed, the company predicts that half of all new vehicles will have the technology in Europe by 2013.

Peter Fouquet, president of Bosch in the UK, said that a Start/Stop system can reduce a vehicle’s CO2 emissions by eight per cent when driving in the city and up to 15 per cent in busy city traffic.

“Start/Stop is one exemplary fuel saving technology that further reduces CO2 emissions,” he added.

The technology works by switching off the engine when the vehicle comes to a stop such as at traffic lights. When the foot is taken off the brake, the engine then restarts.

Earlier this month, transport secretary Philip Hammond announced the creation of a Clean Air Fund for London, which will impose measures such as a no idling zone.

SBI Energy’s latest market study, The World Market for Microgrids, has identified a unique opportunity for marketers at U.S. military bases seeking reliable and secure energy. The majority of U.S. military bases are powered by public electrical grids, which in some instances lead to as many as 300 power outages per year. These interruptions weaken military readiness and security. In the face of a terrorist attack or natural disaster, reliance on conventional energy supplies may be inefficient and may even be detrimental to military functions. Microgrid advantages in this case are clear: in the face of a massive power outage, the microgrid is able to separate from the main utility grid—if it is not already islanded —and keep vital facilities and operations powered.

As U.S. Representative Martin Heinrich of the 1st Congressional District of Mexico says, “Microgrids provide a more secure infrastructure for our military–both here and abroad. Growth in the military microgrid segment will rise by 375% from 2010 to 2020. Total market value in this segment is projected at $1.6 billion in 2020, up from $.33 billion in 2010 and electrical output will increase from .13 GW in 2010 to .60 GW in 2020.

As the microgrid expands its realm of operations in commercial, military and industrial segments, the costs associated with implementation are decreasing. Installation price can vary wildly depending on a number of factors–including the size, scope and technological advancement of a specific project. From solar–hybrid implementations in small remote villages to giant undertakings such as the $4 billion Crystal Island project, the future will become less individualized and more mass, factory built–greatly reducing costs associated with implementing a microgrid.

The World Market for Microgrids provides an in–depth analysis of the economic drivers and challenges and key social and political factors facing the microgrid industry. The market study also reports historical market and growth in dollars (2006 – 2010), broken down into five market segments, as well as future forecast data through 2020. Furthermore, a new chapter segment featured in all 2011 reports examines the current and upcoming employment opportunities that will be created as microgrid manufacturing and installations ramp up. Microgrid activity around the world, including information on the overall electricity situation and specific microgrid projects, is examined, as are the company strategies of 15 leading industry manufactures and new technologies.

Wind Prospect will make Second Wind’s Triton sodar system available sodarthrough rental contracts. The rental option enables developers to collect wind data using the wind industry’s market-leading remote sensing technology under flexible financing terms. Most of the world’s leading wind developers already use Triton to measure wind resources across the full swept area of the turbine’s rotor, reducing uncertainty in hub height wind speeds and enhancing project financing terms. Wind Prospect will initially be using these two Tritons to support five wind development projects in Poland.

Poland has vast onshore and offshore wind resources and is doubling its wind power capacity every year. Spurred by its own economic growth and European Union renewable energy mandates, Poland is predicted to expand its wind power twentyfold by 2020.

Wind Prospect gained experience with Triton from using it on international wind power projects in Europe, Australia and North America.

“Wind Prospect has accumulated extensive experience in analyzing Triton data for more than two years,” said Jason Wood, Second Wind’s director of European sales. “We have a high level of confidence in Wind Prospect’s understanding of the use of Triton throughout all phases of wind farm development, including site selection and data analysis. This experience delivers maximum value to our customers in their use of Tritons as part of an integrated wind assessment campaign.”

Triton is an advanced remote sensing system that uses sodar (sound detection and ranging) technology to measure wind in the areas that most affect a wind turbine’s performance. By measuring wind speeds at the turbine rotor’s hub height and beyond, Triton reduces uncertainty in annual energy production (AEP) forecasts. Easy to install and capable of autonomous operation, Tritons are being used throughout the wind industry, alone or in conjunction with met towers, to streamline the wind farm development process and to improve wind farm operations.

“Wind Prospect is filling an important niche in Poland’s wind energy market by providing Tritons to developers through rental agreements,” Wood said. “Wind developers have to figure their budgets very closely in the prospecting and assessment phases, and there sometimes isn’t room for equipment purchases. Renting is the perfect solution.”
