Studies on Ideal and Actual Efficiency of Solar Polymer Electrolyte Fuel Cell
Among the different types of fuel cells, the PEMFC is more advantageous because of its operation condition. To satisfy the world energy thirst an integrated hydrogen production system and utilization unit must be developed.
SuperGreen Ships and Barges
Not unlike washing machines, clothes, cars, and buildings, ocean going ships eventually wear out and require replacement. The next generation of ships may well require onboard ballast water treatment capability and double hulls.
TERRESTRIAL SOLAR CELL SURPASSES 40 PERCENT EFFICIENCY
This technology will continue to dramatically reduce the cost of generating electricity from solar energy as well as the cost of materials used in high-power space satellites and terrestrial applications.
3 Dimensional Solar Cells
Solar3D, Inc. is developing a breakthrough 3-dimensional solar cell technology to maximize the conversion of sunlight into electricity. Up to 30% of incident sunlight is currently reflected off the surface of conventional solar cells, and more is lost inside the solar cell materials. Inspired by light management techniques used in fiber optic devices, Solar3D's innovative solar cell technology utilizes a 3-dimensional design to trap sunlight inside micro-photovoltaic structures where photons bounce around until they are converted into electrons

AltEnergyMag Interview - Solar System Safety
Brent Harris, P.Eng, is CTO of Sustainable Energy Technologies, and a co-founder of the company. He led the development and commercialization of the company's technologies, from early demonstrations to the launch of its latest Sunergy inverters. Mr. Harris has a passion for decentralized energy in general and for solar power in particular. He is an active proponent of changes to the management and regulation of our electric system that will enable greater adoption of decentralized and renewable energy technologies. Mr. Harris is a member of the board and treasurer of WADE Canada, and was a member of the board of directors of the Canadian Solar Industries Association from 2005-2008.
Balance of System Solar Solutions
SolarBOS was the first company to build a combiner box around a flexible platform where the system integrator could specify the number of fuses and enclosure rating. While this seems pretty simple in hindsight, back in 2004 this was brand new and allowed integrators a lot of flexibility on the design of the DC side of the project.
Bankable Projects Needed
May 18th & 19th saw the renewables sector come together for the annual All-Energy conference and exhibition in Aberdeen. While developers, manufacturers, enterprise agencies and financiers debated and endorsed the industry's progress in Scotland and pondered on the development of the offshore wind supply chain, the Scottish European Green Energy Centre (SEGEC) felt it prudent to remind delegates that many of the current business models won't deliver the project investment needed in the future.
Belgian Solar Market Cooling Down Following End of 2009 Boom
The end of 2010 saw an accumulated volume of approximately 740 MW in Belgium, enabling the country to establish its 5th position in the EU ranks, before France. 88% of capacity is in Flanders. While Hernieuws and VREG data totalled up to 385 MW for Belgium in 2009, EurObserv'ER recently counted 363 MWp DC capacity. Based on the original AC data, 2010 could have seen growth of 354 MW. With a population of 10,8 million, the country as a whole would have reached a level of 68 W of installed solar capacity per inhabitant (75 Wp DC).
Canadian-designed Battery Backup System Maximizes Solar Power
Douglas Caldwell's AC micro grid for his home, is a sleek combination of Sanyo HIT solar panels, Enphase micro-inverters and a Schneider Electric Xantrex XW Series battery backup system, which provides uninterrupted power for occasions when the grid is down.
