An ultra-powerful laser can turn regular incandescent light bulbs into power-sippers, say optics researchers at the University of Rochester. The process could make a light as bright as a 100-watt bulb consume less electricity than a 60-watt bulb while remaining far cheaper and radiating a more pleasant light than a fluorescent bulb can.
Solar electricity has a future: It is renewable and available in unlimited quantities, and it does not produce any gases detrimental to the climate. Its only drawback right now is the price: the electric power currently being produced by solar cells in northern Europe must be subsidized if it is to compete against the household electricity generated by traditional power plants.
Researchers from around the world will present the latest breakthroughs in electro-optics, lasers and the application of light waves at the 2009 Conference on Lasers and Electro-Optics/International Quantum Electronics Conference (CLEO/IQEC) May 31 to June 5 at the Baltimore Convention Center in Baltimore.
Obducat's new lithography system is ready to be launched. The system, named Sindre 400, is the world's first fully automated system for high volume manufacturing of LEDs. Sindre 400 is a vital contribution to the development within CleanTech, since, thanks to greatly increased energy and material efficiency, it reduces the use of natural resources.
By combining the best of two different distance measurement approaches with a super-accurate technology called an optical frequency comb, researchers at the National Institute of Standards and Technology (NIST) have built a laser ranging system that can pinpoint multiple objects with nanometer precision over distances up to 100 kilometers. The novel LIDAR ("light detection and ranging") system could have applications from precision manufacturing lines on Earth to maintaining networks of satellites in perfect formation, creating a giant space-based platform to search for new planets.
Long-life LED luminaires in hard-to-reach recesses are providing a unique viewing experience at the new Yitzhak Rabin Museum in Tel Aviv and minimizing disruption to visitors from unplanned maintenance.
Futuristic discs with a storage capacity 2,000 times that of current DVDs could be just around the corner, thanks to new research from Swinburne University of Technology. For the first time researchers from the university's Centre for Micro-Photonics have demonstrated how nanotechnology can enable the creation of 'five dimensional' discs with huge storage capacities.
Researchers have created a new type of invisibility cloak that is simpler than previous designs and works for all colors of the visible spectrum, making it possible to cloak larger objects than before and possibly leading to practical applications in "transformation optics."
Research and Markets, leading source for international market research and market data, has announced the addition of the "Nanotech: Making Photovoltaics Possible" report to their offering. Photovoltaics is the technical term for generating electricity from light and today it is fast becoming an important industrial product.
Salad dressing aside, a pile of spinach has more nutritional value than a wedge of iceberg lettuce. That's because darker colors in leafy vegetables are often signs of antioxidants that are thought to have a variety of health benefits. Now a team of plant physiologists has developed a way to make lettuce darker and redder - and therefore healthier - using ultraviolet light-emitting diodes (LEDs).
