From Darwin to Adelaide, the length of Australia, 3010 kilometres, without fuel!
On 19 October 30 cars will be jostling for position at the start of the 7th World Solar Challenge in Darwin, Australia. After winning in 2001 with Nuna I, the Nuon Solar Team, from the Netherlands, will be bidding to retain their title. The strong team of twelve from Delft University of... view more (2003-10-17)

Camcorder fueled with hydrogen
Peep! "Please switch off. Power supply almost exhausted." Every day millions of mobile phone, palmtop, notebook, portable CD player and camcorder users are driven to fury by this warning. Without a power source, this wonderful new wealth of modern electronics is of no use at all. Yet the mobile and... view more (2001-04-19)

Unique Quantum Effect Found in Silicon Nanocrystals
Researchers at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL), collaborating with Innovalight, Inc., have shown that a new and important effect called Multiple Exciton Generation (MEG) occurs efficiently in silicon nanocrystals. MEG results in the formation of more... view more (2007-07-26)

A New Russian Meteorite?
On Thursday 3 October, residents of the village of Bodaibo in the Irkutsk region of Siberia witnessed the fall of a large glowing object from space. Witnesses saw a large fireball in the sky, followed by a thunder-like sound, a flash of light, and a small earth tremor. Scientists from the Institute... view more (2002-10-04)

New study: Why solar cells lose potency
Commercial products such as laptop computer monitors and solar-powered calculators are constructed from a light-sensitive material with a peculiar problem: When exposed to intense light, it forms defects, reducing the efficiency of the solar cells by 10 to 15 percent.   view more (2005-06-20)

Perfecting a solar cell by adding imperfections
Nanotechnology is paving the way toward improved solar cells. New research shows that a film of carbon nanotubes may be able to replace two of the layers normally used in a solar cell, with improved performance at a lower cost. Researchers have found a surprising way to give the nanotubes the... view more (2008-06-17)

Voyager data may reveal trajectory of solar system
Nearly 30 years after launch, the two Voyager spacecraft are still operational and returning useful data. In their early years they produced some of the first close up images of the large outer planets.   view more (2006-05-31)

UCLA engineers pioneer affordable alternative energy-solar energy cells made of everyday plastic
Researchers at the UCLA Henry Samueli School of Engineering and Applied Science hope to meet the growing demand with a new and more affordable way to harness the sun's rays: using solar cell panels made out of everyday plastics.   view more (2005-10-10)

Star on a Hubble diet
How heavy can a star be? This conundrum has haunted astronomers for decades. Theory indicates that there should be an upper stellar mass limit somewhere between 120 and 300 solar masses. Even though heavy stars are very bright, measurements of their masses can be complicated.   view more (2006-12-12)

Major grant drives forward cost efficient solar power
Whether the search for alternative energy sources is driven by our concern about global fossil fuel supplies or over the atmospheric effects of burning of fossil fuels, the government has laid out its aim to cut carbon dioxide emissions by 60% of 1990 levels by 2050, and aims to over- achieve its... view more (2004-09-14)

Solar cell manufacturing process examined with a view to increasing cell efficiency
Electricity generated from solar cells is often quoted as being the solution to our climate problems. Unfortunately, this method of energy generation is quite inefficient. Overcoming this inefficiency is key to the widespread commercial acceptance of solar energy.   view more (2006-04-03)

Winds of 320 000 kilometres per hour on the Sun
The SUMER instrument on the ESA-NASA SOHO spacecraft has measured amazing wind speeds during its observations of the Sun. It sets a new record in its examination of two loops of gas arching in the solar atmosphere, where NASA`s TRACE satellite spotted bright blobs of gas. Shifts in the wavelength... view more (2002-05-17)

Philips patents TU Eindhoven's energy return system
An increasing number of private individuals supply their excess energy, from external energy sources (windmills and solar cells), to the electricity grid and only take energy from the grid when necessary.   view more (2008-01-25)

Solar Contribution To 'Global Warming' Predicted To Decrease
New research on the sun's contribution to global warming is reported in this month's Astronomy & Geophysics. By looking at solar activity over the last 11,000 years, British Antarctic Survey (BAS) astrophysicist, Mark Clilverd, predicts that the sun's contribution to warming the Earth will... view more (2003-10-01)

Silicon Thin-Film Solar Cells Gaining In Efficiency
An important goal of modern energy research is to directly convert sunlight into electricity at low cost. Silicon thin-film solar cells promise comparatively lower costs than conventional solar cells. However, to become a mass product of the future, the efficiencies of large-area modules must climb... view more (2002-08-08)

Cost Competitive Electricity from Photovoltaic Concentrators Called 'Imminent'
Solar concentrators using highly efficient photovoltaic solar cells will reduce the cost of electricity from sunlight to competitive levels soon, attendees were told at a recent international conference on the subject. Herb Hayden of Arizona Public Service (APS) and Robert McConnell and Martha... view more (2005-07-18)
