• Study: Costs of solar panels far exceeds benefits

    There is growing interest in solar power, but the cost of solar panels still exceeds their benefits, a University of California economist says; even under the most extreme assumptions — a 5 percent annual increase in electricity costs and 1 percent interest rate — the cost of solar PV is about 80 percent greater than the value of the electricity it will produce

  • BlastGard shows new airport security tool

    A mobile suspect package removal unit with blast-mitigating bomb receptacle will help hold and remove suspected explosive packages until the bomb squad arrives; new system would make it unnecessary to shut down an airport for long periods, which is a good thing, since it is estimated that an airport incurs losses of approximately $150,000 for every minute it is shut down

  • How to protect corporate secrets from outsiders -- and insiders

    A secret can be lost in the blink of an eye, but getting information back under wraps can take forever; John Edwards offers a few useful tips on how corporations can become more secure

  • Toshiba tests liquid sodium fast reactor

    Toshiba notices the growing interest in nuclear power, and opens high temperature liquid-sodium test loop at its Yokohama Complex; company says it will enhance its sodium-related technology in readiness for future business expansion in this promising market

  • Moth eyes inspire more efficient solar cell design

    Moth eyes do not reflect light: They have orderly bumps on their corneas, and the the array of bumps creates a situation in which almost no reflection exists, thus keeping the defenseless moth hidden from nocturnal predators; researchers want to increase the efficiency of solar panels by emulating moth eyes, allowing the panels to absorb and utilize — rather than reflect and waste — more of the sun’s light

  • New U.K. nuclear plants to fund eventual decommissioning

    New U.K. nuclear power station operators will be required to set aside money for their eventual decommissioning and waste costs

  • Maintaining security at Israel's Ben Gurion Airport

    In 2006, Israel’s Ben Gurion Airport handled 9 million international passengers and 405,000 domestic passengers; it did so while being among the world’s most secure — if not the most secure — airports; two Israeli companies, Hi-Tech Solutions and Rontal, made their own contributions to achieving that level of security

  • Solar energy conversion breakthrough

    Scientists say that sunlight falling on only 9 percent of California’s Mojave Desert could power all of the U.S. electricity needs — if the energy could be efficiently harvested; this is a big “if,” since current-generation solar cell technologies are too expensive and inefficient for wide-scale commercial applications; Northwestern University researchers show a way to increase solar cell efficiency

  • DOE, partners test commercial geothermal technology in Nevada

    Geothermal energy attracts more and more attention, and for good reason: One cubic kilometer of hot granite at 250 degrees centigrade has the stored energy equivalent of 40 million barrels of oil

  • Researchers: Computers' "secure" memory systems utterly insecure

    Attacks on computer memory reveals vulnerability of widely used security systems; information stored in a computer’s permanent memory readily accessible to hackers; laptops especially vulnerable

  • Bacteria and nanofilters -- the future of clean water technology

    University of Nottingham researchers combine contaminant-eating bacteria with nanoscale filtration membranes to purify fouled water; additional side benefit: The waste products created by purifying water have a very high calorific value, and can be used as fuel

  • Astrium’s Spanish expansion

    With growing interest in exploiting space-based assets for observation and monitoring, Astrium collaborates with Catalan, Spanish companies to create Infoterra SGSA; new venture will be exclusive distributor of TerraSAR-X high-resolution radar data for the Spanish market

  • Major security vulnerabilities in proposed World Trade Center complex

    Security experts say that the proposed World Trade Center complex has major security flaws: Towers contain too much glass; they are too close to the street where thousands of uninspected trucks and cars will drive daily; and the buildings do not meet Department of Defense or DHS blast standards

  • Cleaner water through nanotechnology

    As global warming causes more and more countries to have less and less fresh water for human consumption and irrigation, the purification and re-use of contaminated water becomes more urgent; Aussie researchers offer a nanotechnology-based method to purify water which is more effective and cheaper than conventional water purification methods

  • Utility plans first U.S. coal-fired plant to capture CO2

    Tenaska proposes a new 600-megawatt, coal-fired power plant in Texas which would be the first to capture and store carbon dioxide emissions underground
