The Frisian Solar Challenge for boats
Image Gallery (20 images)
Human beings respond well when challenged and the bolder the challenge, the greater the result. The Frisian Solar Challenge for boats is proof of this and its second running later this month portends a new age – one of silent, non-intrusive and respectful water-based leisure and ultimately, a plethora of distributed power generation solutions. The inaugural 2006 Challenge turned the Dutch province into a hotbed of commercial sustainable energy development and the week-long solar-boat tour of the region has developed a most intriguing man versus machine competition. From June 22 to June 28, Friesland will be home to the world’s largest race of solar vessels: The Frisian Solar Challenge. The race runs along the 220-kilometres-long route of the Frisian Eleven Cities route already famous as the birthplace of competitive skating and the pictured space-age boat is the current favourite for the race with its expected 20 km/h top speed.

Thin film solar cell production breakthrough
Image Gallery (2 images)
May 15, 2008 Advancing a viable market for photovoltaic solar energy involves a balancing act between creating efficient solar cells and at the same time reducing the cost of the manufacturing process. Solar efficiency has been demonstrated to levels as high as 22% (a record set by SANYO last year), and although HelioVolt Corporation's latest announcements concern technology that is only delivering 12.2% conversion, the company has made great strides on the other side of the equation. Its proprietary FASST reactive transfer printing process has produced solar cells in a record setting six minutes, according to HelioVolt that's 10 to 100 times faster than current production of thin-film photovoltaics and could lead to manufacturing costs of less than $1 per watt.

Researchers developing solar technology that works at night
Image Gallery (2 images)
January 4, 2008 Idaho National Laboratory (INL) reports that research conducted in conjunction with partners at Microcontinuum Inc. (Cambridge, MA) and Patrick Pinhero of the University of Missouri is promising a method for developing cheap solar energy technology that could be imprinted on flexible materials and still draw energy after the sun has set. The technology uses a special manufacturing process to stamp tiny square spirals, or “nanoantennas”, of conduction metal onto a sheet of plastic and the team estimates individual nanoantennas can absorb close to 80 percent of the available energy in comparison to current commercial solar panels which usually transform less that 20 percent of the usable energy that strikes them into electricity – this is even more impressive than the 30% conversion rate offered by the recently discussed development of nano flakes.
