    Motorcycle Engines Powered by Compressed Air

    New Design for Motorcycle Engines Powered by Compressed Air

    FOR IMMEDIATE RELEASE

    Jason Socrates Bardi, +1 301-209-3091, jbardi@aip.org

    College Park, MD (June 22, 2010) -- Most motorcycles in the world today use engines that burn gasoline, contributing to greenhouse gasses and adding air pollution to the surrounding area. Now two scientists in India have conceptually designed a new, cleaner motorcycle engine that uses compressed air to turn a small air turbine, generating enough power to run a motorcycle for up to 40 minutes.

    Their design, described in a recent issue of the Journal of Renewable and Sustainable Energy, could be combined with a compressed air cylinder as a replacement for traditional internal combustion engines. In areas where motorcycles are a major source of public transportation, such a technology could cut emissions substantially if widely implemented.

    According to Bharat Raj Singh, one of the two authors on the paper and a researcher at the SMS Institute of Technology in Lucknow, India, some 50 to 60 percent of present emissions in some areas could be reduced with the new technology, though a number of technical challenges remain. Designing a compact but high-capacity air tank to store sufficient "fuel" for long rides is a major hurdle. Existing tanks would require someone to stop about every 30 km (19 mi) to swap tanks.

    The article, "Study of the influence of vane angle on shaft output of a multivane air turbine" by Bharat Raj Singh and Onkar Singh was published May 6, 2010 in the Journal of Renewable and Sustainable Energy. See: http://jrse.aip.org/jrsebh/v2/i3/p033101_s1

    Unexpected observation of ice at low temperature, high pressure questions ice, water theory

    Scientists at Oak Ridge National Laboratory studying super-cold states of water discovered a pathway to the unexpected formation of dense, crystalline phases of ice thought to exist beyond Earth's limits. Their findings, reported in Nature, challenge accepted theories and could lead to better understanding of ice found on other planets, moons and elsewhere in space.
