We comprehend that the strength of a magnet is fabulously powerful. We are capable to really thoroughly and closely question or examine this attraction and resistance by bringing more than one magnets together.

Efforts to develop a massive environmentally friendly power plant combining photovoltaic generators and windmills that will float on the sea are progressing well, according to a team of scientists at Kyushu University. The planned plant will measure two kilometers by 800 meters and will be equipped with light-emitting diodes that shine light into the sea to promote seaweed growth, which in turn will absorb carbon dioxide and attract fish.

The government plans to announce policy measures aimed at halving the price of solar power generation in the next three to five years as part of its action plan on greenhouse gas emissions, government sources say. According to the sources, the measures will form part of an action plan designed to bring about a 60 percent to 80 percent cut in carbon dioxide emissions by 2050 and thereby create a low carbon-emission society.

Converting livestock manure into a domestic renewable fuel source could generate enough electricity to meet up to three per cent of North America's entire consumption needs and lead to a significant reduction in greenhouse gas emissions (GHGs), according to new research.

From Holland, the country famous for its windmills, comes a new design for home wind power. Looking like an eggbeater, it spins quieter and at lower wind speeds than a lot of traditional propeller-type turbines. It's now standard for big wind turbines to have propeller blades. Much of the turning force is generated at the tips, which slice perpendicularly through the air, causing a swooshing noise that some residents nearby have said they find unnerving.

A new breed of solar tower may soon be sprouting up in Namibia, providing the nation with a carbon-free source of electricity and food during the day and night. At one and a half kilometers tall and 280 meters wide, these massive solar updraft towers could potentially produce 400MW of energy each - enough to power Windhoek, the nation's capital. Proposed by intellectual property company Hahn & Hahn, the towers generate energy by forcing heated air through a shaft lined with wind turbines. Additionally, the base of each tower will function as a 37 square km greenhouse where crops can be grown.

Spain has set a record this week by powering 29-40% of its electricity needs from wind energy. A huge 11,180 MW was generated on Thursday when high winds blew through north west Spain. When demand was lower early in the morning, wind energy supplied 40% of the country's requirements whilst later on when demand rose, wind energy supplied 29%. This year wind turbines have supplied 11.5% of electricity demand in Spain positioning the country as the third biggest producer of wind energy next to Germany (second) and the US (first). There is a national target of reaching 20,000 MW by 2010. This compares with a figure of just 7300 MW likely to be operational in the UK by 2010 (the number currently built or with planning consent). Companies with a significant presence in Spain are Iberdrola, Acciona and Endesa.

Working in Haiti, Shawn Frayne, a 28-year-old inventor based in Mountain View, Calif., saw the need for small-scale wind power to juice LED lamps and radios in the homes of the poor. Conventional wind turbines don't scale down well-there's too much friction in the gearbox and other components. "With rotary power, there's nothing out there that generates under 50 watts," Frayne says. So he took a new tack, studying the way vibrations caused by the wind led to the collapse in 1940 of Washington's Tacoma Narrows Bridge (aka Galloping Gertie).

Despite some naysayers, wind power turbines are being erected in five cities in the metro area; Anoka's is near the high school. Wind power turbines are going up in five metro cities, with Anoka set to get one on Monday, as a multi-city consortium moves forward with plans to use recycled windmills to generate renewable energy.

With fewer people taking lengthy, far off vacations, a camping trip is becoming the destination of choice. While they are there, many people would like to continue living in the green manner they are used to but they do not want to have to haul everything along.

Abstract: The sun may soon power many more homes and appliances, thanks to chemists at Idaho National Laboratory and Idaho State University. They have invented a way to manufacture highly precise, uniform nanoparticles to order. The technology, which won an R&D 100 Award this year, has the potential to vastly improve photovoltaic cells and further spur the growing nanotech revolution. Nanoparticle breakthrough could improve solar cells Idaho Falls, ID | Posted on October 29th, 2009 INL chemist Bob Fox and his ISU colleagues were looking for a better way to make semiconducting nanoparticles for solar cells. When the researchers introduced "supercritical" carbon dioxide - CO2 that behaves like both a gas and a liquid - to their reactions, they generated high-quality nanoparticles at low, energy-saving temperatures. And, surprisingly, the nanoparticles were incredibly uniform. With subsequent tweaking, the team figured out how to make nanoparticles of prescribed sizes - anywhere from 1 to 100 nanometers - with unprecedented precision. Because the properties of nanoparticles are so strongly size-dependent, the implications of this breakthrough are vast.
