Microbial Fuel Cells - Principles and Applications
The impending energy crisis and global warming warrant the need for eco-friendly sources of energy. Non-conventional, carbon-neutral sources of energy such as solar, wind, biomass and nuclear energy are being explored and exploited to a considerable extent. At this juncture, when the atmosphere is laden with greenhouse-gases, we can least afford to release stored carbon. The following article gives an account of the basic principles involved in the functioning of Microbial Fuel Cells and the major applications of Microbial Fuel Cell technology, as it stands today.
Next Generation Green Tech for the Home
Currently there are two wireless networks for home entertainment, data networks and in home communication - the data network which usually runs on one of the various flavors of Wi-Fi and the cordless phone systems using the so-called DECT standard. Even though both technologies are very mature and effective, because of their high bandwidth and data throughput, they require a lot of power.
Overview of Municipal Solid Waste in Brazil
Brazil, the third largest territory in the Americas and the fifth largest in the world, with nearly 200 million people, has suffered with the environmental problems generated by the traditional model of dumping their waste in landfills. That process unfortunately, turns worse by the inhabitants practices of simply throwing the waste away on areas without any control or care, constituting the so-called "lixões" (slang meaning "big garbage" in Portuguese language).

Potential market for residential fuel cells and combined heat and power systems.
Fuel cells are already powering hundreds of installations world-wide from cell phone towers to large scale facilities. In the United States fuel cells are providing low-carbon electricity to businesses such as Whole Foods grocery stores in New England and Sierra Nevada's brewery in California. Fuel cell power systems can also be used to generate power in your home.
Solar Industry Growing; Obstacles Remain Poll Says
According to a new poll from Droege & Comp. and Gibbs & Soell, U.S. Solar businesses are poised for strong growth in 2010 and significant growth in 2011. However, respondents indicate that obstacles still remain. Favorable legislation, customer knowledge and heightened marketing will be keys to the expansion of their business.
Participants included nearly 100 professionals representing key areas of the solar business value chain. Results from the 2009 Solar Industry Monitor were unveiled at the 2009 Solar Power International Show in Anaheim, Calif.

Sustainably Producing Algae Biofuels for a Clean Energy Future
Algae biofuels promise greater productivity, and can be grown on nonarable land, and with mostly non-potable water. However, as with any new technology—especially in the biofuels space— many questions about its technical potential and sustainability remain.
The Italian PV market to grow to 15 GigaWatt
Interview with Federico Brucciani, independent solar PV expert and author of the report "The Italian PV market". Brucciani is very optimistic about market growth in his country. He says that grid-parity will be reached in all market segments within the next 6 to 8 years. He adds that the market is becoming more sustainable than in Spain and that a new and appealing FiT program can be expected as a follow up to the current program, which has met with so much success.
The Promise of Solar Power Has Roots Deep in the Space Program
With Presidential direction and Congressional support, NASA's wellspring of talent could help foster the creation of solar power satellites - spacecraft that circle the Earth and beam the energy they generate down to the ground for distribution as electricity.
Third-Gen Thin-Film Solar Technologies: Forecasting the Future of Dye Sensitized and Organic PV
Third-generation thin-film solar devices are beginning to emerge in the marketplace after approximately 20 years of research and development, due to the insight of leading material developers such as Konarka and Plextronics in the organic photovoltaics (OPV) domain, and Dyesol, EPFL, G24i, Mitsubishi and Peccell on the dye-sensitized cells (DSC) front. Both DSC and OPV technologies lag far behind on the efficiency curve when compared to conventional solar (i.e., >20 percent efficiency), so they will likely succeed in markets where their low cost, substrate flexibility, and ability to perform in dim or variable lighting conditions provide them with a significant competitive advantage.
A Review of "Six Degrees Could Change the World"
Six Degrees Could Change the World is the latest in a steady stream of documentaries to focus on concerns about the environment and global warming since Al Gore's An Inconvenient Truth won the Academy Award for Best Documentary. Six Degrees , though, takes these concepts in a fresh, new direction and in now way, shape or form attempts to imitate Gore's film.

Emerging Trends in Commercial Biofuels Production
The challenges from agricultural requirements to produce food and energy can only be met if we use all options available for increasing productivity and safeguarding harvests. Innovative crop protection products and plant biotechnology provide solutions to reduce the energy consumption in agriculture while conserving natural resources and contributing to mitigate the effect of climate change.
Fuel Cells Enlist in Armed Forces
Fuel cells have the potential to dramatically change how the military carries out its missions, and how soldiers operate in the field. With the largest, most technologically advanced military in the world, the U.S. armed services use an immense amount of fuel and electricity, and any use of alternative energy would have positive effects on reducing greenhouse gas emissions. However, fuel cells are of particular interest to the military not for their environmental savings, but because of unique technical features that can aid soldiers in the field.
