NextFest 2006: The Future of Earth Toys

In addition to showcasing some of the globe's most advanced robotics, NextFest 2006 also included some of the world's most advanced environmentally friendly gadgets.

Principal Voices Speak: Renewable Energy Paramount

According to the program introduction, alternative energy accounts for one-half of one percent of all energy used today. Breaking free of the hydrocarbons, which accounts for a whopping 80 percent of energy used, has truly become a stated geopolitical concern

REVERSING CLIMATE CHANGE?

I would like to point towards one combination of existing technology that I am convinced could actually do the job of lowering atmospheric carbon concentrations and thus reverse climate change

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 - Christopher Associates and the Solar Industry

Starting in a two-room office in 1977, Christopher Associates quickly expanded by focusing on technical service and an international product mix. By 1984, the company grew to become one of the leading suppliers to the printed circuit industry. Today, its customer base includes more than 1,200 companies worldwide in the Printed Circuit Fabrication and Assembly industries.

Altenergymag Interview - PV Product Distribution

Krayden, Inc. offers numerous solutions for the solar energy industry. As an authorized distributor of leading manufacturers serving the photovoltaic market, including Dow Corning, Henkel Loctite, 3M, Humiseal, FCT Assembly, Lord, and Cytec, and others the company is able to supply a full line of coatings, tapes, PV sealants, conductive Inks, PV adhesives, lead-free solder, and PV potting agents. Here we catch up with Wayne Wagner, Krayden, Inc.'s president, to see how the company's PV side of the business is growing.

Altenergymag Interview - Risk Management in the PPA Marketplace

Solar Insure is a California owned Independent insurance brokerage dedicated to providing our clients with the highest quality professional risk management & insurance services, while delivering competitively priced alternative energy insurance products.

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).
