The ocean-current technology developer Ocean Renewable Power Company (ORPC) has been working on a pilot version of its cross-flow turbine since 2004. Over the last six years, the company has learned a number of important lessons about the difficulties of deploying energy technologies in the marine environment. ORPC's 30-kw unit, which was installed in the Bay of Fundy off the coast of Maine, was battered by bad weather and did not function properly due to wrongly-sized parts. But the company announced today that the test of its 60-kW pre-commercial device, known as the TGU, was running smoothly and had delivered compatible electricity to the Maine grid at a consistent output. No word on how much electricity was actually generated. The machine was installed in Cobsook Bay in Eastport Maine last fall. Source - RenewableEnergyWorld
Fuel cells are ideal for space missions for many reasons. Fuel cells can run for long durations without interruption as long as fuel is supplied. They produce electricity very efficiently and reliably. In addition, the light weight of fuel cells reduces total launch pad weight.
Electric vehicle owners will influence an extensive network of charging stations being installed in Madison, Wisconsin by MGE. In a story produced by StoryBridge.tv, see how MGE will use driver input to configure its power grid for a new wave of green transportation.
Missouri Department of Transportation St. Clair Maintenance Facility installation of 48 SolarSheats Solar air panels deployed on two structures (one with eight and one with 40) and two solar hot water systems each using four 4' x 8' flat plate collectors both on the same structure (one for a car wash and the other for domestic hot water).
Due to its stability, chemical purity, transmissivity to light, and heat resistance, quartz has for many years been vital to the production of semiconductors for the electronics industry. The material is virtually inert, very durable and will withstand the high temperatures associated with semiconductor fabrication and testing.
Photon Enhanced Thermionic Emission or PETE, simultaneously combines the heat and light from solar radiation to create electricity. Traditional solar panels utilize photovoltaic technology, which is flawed in that it decreases in efficiency as temperature rises. This is an obvious problem, seeing as the sun produces both light and heat. The new process of PETE, actually increases efficiency of the panels as the heat index increases.
Atlantis Resources Corporation (“Atlantis”) unveiled the largest and most powerful tidal power turbine ever built, the AK1000™, yesterday at Invergordon, Scotland. The AK1000™ is due for installation at a dedicated berth at the European Marine Energy Centre (“EMEC”), located in Orkney, Scotland later this summer. Despatching 1MW of predictable power at a water velocity of 2.65m/s, the AK1000™ is capable of generating enough electricity for over 1000 homes. It is designed for harsh weather and rough, open ocean environments such as those found off the Scottish coast. The turbine incorporates cutting edge technology from suppliers across the globe, has an 18 meter rotor diameter, weighs 1300 tonnes and stands at a height of 22.5 meters. The giant turbine is expected to be environmentally benign due to a low rotation speed whilst in operation and will deliver predictable, sustainable power to the local Orkney grid.
An alliance of U.S. home appliance manufacturers, energy and water efficiency organizations, consumer groups and environmental organizations have agreed to improved efficiency standards and tax policies for refrigerators, freezers, clothes washers, clothes dryers, dishwashers and room air conditioners. The agreement could save enough energy to meet the total energy needs of 40 percent of American homes for one year and the amount of water necessary to meet the current water needs of every customer in the City of Los Angeles for 25 years, the partners believe. Further, global warming CO2 will be reduced by 550 million metric tons over the same time period, without considering the emissions reductions from smart appliances. The partners have called for new national minimum efficiency standards, production tax credits for super-efficient appliances, and the inclusion of smart grid readiness as a feature of future ENERGY STAR qualified appliances.
We got the opportunity to interview the three leading teams in the EcoCAR Challenge namely Mississippi State University, Virginia Tech and Pennsylvania State University. These are the future leaders in the alternative energy transportation industry and it shows in their enthusiasm.
The Progressive Insurance Automotive X-Prize is a huge undertaking involving Establishing a venue, staffing, training, developing tests, setting up Consumers Reports Certifications, and taking over the Michigan International Speedway in the outback, near a small town named Brooklyn in our fair State of Michigan.
Innovative technological ideas that originate from small American manufacturing companies often go unrewarded. Why? Because often those companies don't have the ability to take their innovations to the world through an aggressive exporting program.
The West County Wastewater District, located on the San Francisco Bay, provides wastewater collection, treatment, and disposal services for several cities and parts of Contra Costa County. In adopting solar energy, the agency was interested in the long term cost-saving benefits a solar PPA afforded and its no-money down approach. The solar PPA was an excellent solution: the wastewater district pays only for the power the system produces, does not incur operation and maintenance expenses, and sees savings on its electricity bill for the next twenty years-a plus for the District's ratepayers.
Al Gore is upset that Capitol Hill lawmakers are cutting $1.5 billion in renewable energy project loan guarantees to help fund state aid legislation aimed at preventing teacher layoffs and covering Medicaid costs. Renewable-energy groups are furious over the latest raid on the Energy Department loan program, which was also the source of $2 billion in funding for the "Cash for Clunkers" rebates a year ago. "These rescissions put into jeopardy the green jobs that the administration has touted as part of our clean-energy future and put us further behind the rest of the world," Gore said on his website Monday afternoon. The House is slated to vote Tuesday on the $26 billion state aid package the Senate approved last week. Gore said the underlying state aid bill is important legislation, but believes the loan-guarantees cut is the “wrong way on renewables.” Source - E2Wire
The Bio-Bug has been converted by a team of British engineers to be powered by biogas, which is produced from human waste at sewage works across the country. They believe the car is a viable alternative to electric vehicles. Excrement flushed down the lavatories of just 70 homes is enough to power the car for 10,000 miles - the equivalent of one average motoring year. This conversion technology has been used in the past but the Bio-Bug is Britain's first car to run on methane gas without its performance being reduced. It can power a conventional two litre VW Beetle convertible to 114mph. Mohammed Saddiq, of sustainable energy firm GENeco, which developed the prototype, claimed that drivers "won't know the difference". Source - Telegraph.co.uk
Solectria Renewables, in partnership with Outpost Solar, provided two (2) 13kW PVI grid-tied inverters for the 20.16kW system installed at Richland, LLC in Pulaski, Tennessee. Outpost Solar's parking area solar arrays combine function and form by integrating electric vehicle (EV) charging. Outpost Solar strategically decided to incorporate the EV charging stations to accommodate the growing EV market. The solar array will generate over 24,000 kWh of electricity annually which will be used to charge the EVs. The parking area is 55' long and 32' wide and will accommodate 12 electric vehicles. The commissioning ceremony was attended by U.S. Congressman, Lincoln Davis, Pulaski Mayor, Dan Spear, and Pulaski Electric System President, Wes Kelly as well as representatives from Solectria Renewables and Outpost Solar. Congressman Davis is a strong supporter of renewable energy projects and was extremely proud to take part in the ceremony and activate the array. Source AltEnergyMag
