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.
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.

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 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.
Not all the alternative generation of energy is really taken into account because numerous small-scale projects are inevitably overlooked. The Energy Information Administration (EIA) does make available figures on the economy, crude oil prices, and alternative resources to the best of their data collecting ability. This information is almost constantly revised as more data is available but the changes and revisions are not especially dramatic. The change in energy consumption and sources of energy is an evolutionary process and not a revolutionary process.

Joyce Solar Actuators are designed to precisely position smaller solar tracking equipment. Their robust and efficient DC motor (24V or 36V) keeps power consumption to a minimum. Travel speeds remain nearly constant regardless of the load. Ideal for rugged environments common to the solar industry, these cost-effective SA actuators have an IP65 protection rating. Self-locking features in the mechanism ensure that the solar actuator will hold position throughout the daily tracking cycle. Specifications: â€¢ Double clevis mounting for easy installation â€¢ Clutch for overload protection â€¢ Adjustable limit switches for flexible travel settings â€¢ Reed sensor digital feedback for accurate positioning â€¢ Duty cycle is 25% (4 min. running, 12 min. rest) â€¢ Lubricated for life
