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.
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.
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).
Raising capital for an alternative energy company? Consider a Standby Equity Distribution Agreement, or SEDA
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.
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.

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.
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.
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-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.
Warren Buffett, the closely watched investor and mega-billionaire, expects that 20 years from now, all cars will run on electricity. At least, that's what he told Rice University business students at his Omaha headquarters this month when asked for his thoughts on peak oil and replacements for "carbon fuels," the Houston Chronicle reports. Such a rapid transition to electric vehicles could work out well for BYD, the China-based developer of electric vehicles and lithium-ion batteries in which Buffett's Berkshire Hathaway investment firm holds a 10 percent stake. If nothing else, aggressive statements from Buffett, one of the world's highest-profile investors, could help build momentum for the EV market and BYD's growth.
From designer Haneum Lee comes a concept that would power street lights from the energy generated by the trash collected from its base . The lamppost composts the trash and uses the methane byproduct as a fuel to power the lamps. I'm not sure how much trash is needed to power a full side street lamp or if today mostly plastic and paper garbage are well suited for composting but its a novel idea.
Energy management could end up being the killer app for the slow-moving home automation market. Here’s the latest: iControl, a 5-year-old start-up backed by some of the biggest names in venture capital and networking announced this morning that it has launched an energy management product for utilities, broadband service providers and security firms. Out of the gate the company expects its customers to provide consumers a smart thermostat and a gateway for around $70. They expect broadband service providers to offer the energy management service to their customers for free, potentially bundled with a security system, and energy will act as a differentiator or value-add service, instead of a major revenue driver.
Briz Solar Powered Window Blinds designed by Nari Kim and Phullip Lim uses water as a cooling agent. There are two pipes beneath the blinds which help to circulate water which gets evaporated as dry mist. It is this mist which cools the breeze which enters the window. So you get natural air and the sunlight streaming through the blinds is collected and used to power the cooling system.

Professional weather sensors form the heart of large solar plants supporting their operation and performance. Lufft was the first manufacturer to combine several sensors in one housing, bringing the largest multiparameter weather sensor family with 19 members into being. Many of them are well-suited for solar site assessment and continuous monitoring. The most commonly used one is the WS600 delivering data on temperature, air pressure, wind, relative humidity and precipitation. Through its open protocol, it can easily be attached to radiation sensors e.g. from Kipp&Zonen. Other models have an integrated Silicon, Second Class or Secondary Standard radiation sensor.
