Solar cells with 40.7% efficiency made, 58% efficient possible

Scientists from Spectrolab, Inc., a subsidiary of Boeing, have recently published their research on the fabrication of solar cells that surpass the 40% efficiency milestone—the highest efficiency achieved for any photovoltaic device. A pdf with levelized cost of electricity analysis for natural gas, coal and nuclear from 2006 Natural gas is 3.8 to 5.9 cents(US)/kwhCoal …

Uranium from coal flyash waste

A company Wildhorse is going to study extracting Uranium from coal flyash. From the 50 million tons/year of flyash that is generated in Europe, there is 100 to 300 ppm uranium. This would be 5,000 to 15000 tons of Uranium that could be recovered. The US generates over 100 million tons of flyash each year …

Artificial and adjustable nanofluid channels

Nanowerk has a spotlight on artificial adjustable nanofluid channels Flow of fluorescein molecules through an array of five tunable elastomeric nanochannels and their accumulation at an air-filled microscale compartment. Running horizontally at the top is an air-filled microchannel. The nanochannels are triangular and are 80 nanometers high from base to top corner and 600 nm …

My take on Shaping the Future

Science Fiction author Charlie Stross talks about “Shaping the Future” He wrote Accelerando and Singularity Sky among other books. He notes how progress used to measured by top speed, but how that stopped between 1950-1970. I believe that speed will become a useful measure of progress again. I believe that we can and will burst …

China’s economy

A pdf discussing China’s statistics Here is a pdf from Carlsten Holz that examines different China economic growth projections The World Trade Organization data shows that China surpassed the USA in terms of trade in 2006. China’s global trade exceeded $1.758 trillion at the end of 2006.[12]. It first broke the 1 trillion mark ($1.15 …

Discovery of first gene that specifically links calorie restriction to longevity

Loss of only one of the genes, a gene encoding the protein PHA-4, negated the lifespan-enhancing effect of calorie-restriction in worms. And, when researchers undertook the opposite experiment—by overexpressing pha-4 in worms—the longevity effect was enhanced. “PHA-4 acts completely independent of insulin/IGF-1 signaling and turns out to be essential for CR-mediated longevity,” says Panowski. “We …

U of Cincinnati Researchers Shatter World Records with 18mm Long Carbon Nanotube Arrays

UC researchers (in conjunction with First Nano, a division of CVD Equipment Corporation of Ronkonkoma, New York) have produced extremely long CNT arrays (18 mm) on their EasyTube System using a Chemical Vapor Deposition (CVD) process. “First, we were able to grow the arrays up to 18 mm,” he says, ticking off the achievements. “Second, …

Credit: Esko Kauppinen, et al. Researchers have created a hybrid carbon nanomaterial that merges single-walled carbon nanotubes and spherical carbon-atom cages called fullerenes. The new structures, dubbed NanoBuds because they …

Microbial fuel cells generate power from waste water

Generating electricity from renewable sources will soon become as easy as putting a brush and a tube in a tub of wastewater. A carbon fiber, bottle-brush anode developed by Penn State researchers will provide more than enough surface for bacteria to colonize, for the first time making it possible to use microbial fuel cells for …

1-nanometer resolution is NSF CAREER researcher’s goal for optical imaging

Success on this project would make it far cheaper and easier to see and work at near-molecular nanotech levels. “The resolution of most optical microscopes is restricted by the so-called ‘diffraction limit,’ which means we cannot produce optical images with resolutions higher than a few hundred nanometers,” Xu said. “Currently, the most advanced optical microscope …
