An ambitious project that aims to turn arid desert land into a green oasis took a step closer to becoming reality last week when an agreement was signed on the rights to develop a pilot system in Jordan. The Sahara Forest Project’s (SFP) first facility will be located on a 2,000,000 square meter plot of land in Aqaba, a coastal town in the south of Jordan where it will be a test bed for the use of a combination of technologies designed to enable the production of fresh water, food and renewable energy in hot, arid regions.

There’s a number of small portable solar chargers available which are designed to keep mobile gear such as MP3 players and mobile phones powered up when there’s no electrical outlet around. But with people cramming more and more devices on their person or in their cars when heading off the grid, we're seeing a growing number of larger and more powerful units designed for more power hungry devices. The latest is thid portable solar-powered generator from Wagan Tech which provides 1,500 watts of power for seven to eight hours. Read More

With a speed of 88.738 km/h (55.077 mph), the University of New South Wales’ Sunswift IVy has claimed the Guinness World Record for the fastest solar-powered vehicle. The record-beating run took place on January 7 at HMAS Albatross navy base airstrip in Nowra, Australia, and outdid the previous record-holder by more than 10 km/h (6.2 mph). Read More

Researchers have made a two-fold breakthrough in advancing renewable energies with the development of a light sensitive dye which transfers electrons more efficiently than conventional technologies. The new dyes stand to be used in solar electricity generation and in creating hydrogen fuel, which in the past has proven expensive and energy hungry. Read More

In a new, more efficient approach to solar powered microelectronics, researchers have produced a microchip which directly integrates photovoltaic cells. While harnessing sunlight to power microelectronics isn't new, conventional set-ups use a separate solar cell and battery. What sets this device apart from is that high-efficiency solar cells are placed straight onto the electronics, producing self-sufficient, low-power devices which are highly suitable for industrial serial production and can even operate indoors.

Because conventional photovoltaic panels produce electricity directly from sunlight, the energy they generate must either be used as it is produced or stored – either in batteries or by using the electricity to produce a fuel that acts as a storage medium for the energy. Now U.S. and Swiss researchers have developed a prototype device that directly converts the Sun’s rays into fuels that can be stored, allowing the energy to be used at night or transported to locations where it is needed.

Our readers see more than a few eco-products featured here on a regular basis. Very seldom, however, do we have an opportunity to see a "big picture" vision for how an eco-friendly lifestyle can be achieved on a larger scale. Panasonic attempted to give us such a glimpse at the Eco Products 2010 exhibition in Tokyo, devoting an entire booth to demonstrating the company's "comprehensive energy solutions for entire towns."

The lack of support infrastructure is one of the major hurdles for alternative fuel vehicles that use batteries and hydrogen fuel cells. Honda’s vision for solar-powered home-based hydrogen production station is one effort to ease the transition from fossil to alternative fuels and now the company has revealed plans to trial a solar-powered public EV charging station and conduct testing of a range of electric vehicles and technologies in real-world urban transportation environments, starting with Japan.

Portable solar chargers like the U-Powered solar charger from Kiwi Choice are a handy way to keep mobile devices like smartphones, cameras and media players topped up with electricity while on the go. But if you’re looking for a more convenient way to carry a solar charger with you then the GO Solar Power Collection line of clothing from Silvr Lining could prove a good fit. It comprises a range of clothing items that feature pockets to house solar panels to charge up mobile electronic devices. Read More
