Latest Space-based solar power Stories
By O. Glenn Smith As America faces $4.50 a gallon gas, we also know that alternative energy sources - coal, oil shale, ethanol, wind and ground-based solar - are either of limited potential, very expensive, require huge energy storage systems or harm the environment.
MEDFORD, Mass., July 16 /PRNewswire/ -- Wakonda Technologies, Inc., a developer of solar photovoltaic (PV) products, today announced it has raised $9.5 million in Series A financing from ATV (Advanced Technology Ventures), General Catalyst Partners, Polaris Venture Partners, Applied Ventures, LLC (the venture capital arm of Applied Materials, Inc.) and the Massachusetts Green Energy Fund.
Editor's Note: Each Wednesday LiveScience examines the viability of emerging energy technologies - the power of the future. Placing solar panels in space above both night and clouds was first considered 40 years ago. But the estimated cost was, in a word, astronomical.
Research and Markets (http://www.researchandmarkets.com/reports/c92036) has announced the addition of "Analyzing Microwave Power Transmission & Solar Power Satellite Systems" to their offering.
While great nations fretted over coal, oil and global warming, one of the smallest at the U.N. climate conference was looking toward the heavens for its energy.
The next time Jules Verne ATVâ€™s four solar arrays are fully deployed, giving the vehicle a total span of 22.3 m, will be in early 2008, at 28,000 km/h over the South Pacific Ocean.
A NASA satellite designed, built and controlled by the University of Colorado at Boulder is expected to help scientists resolve wide-ranging predictions about the coming solar cycle peak in 2012 and its influence on Earth's warming climate, according to the chief scientist on the project.
Robotic 'spiders' could be the key to building large-scale structures in space, according to ESA's Advanced Concepts Team. The tiny mechanical spiders would inch their way across large nets of fabric in space performing small tasks or lining up to create an antenna or some other structure.
NASA engineers and their industry partners have successfully deployed two 400-square-meter solar sails during ground testing. This is a critical milestone in the development of a unique propulsion technology that uses the Sun to propel vehicles through space.
NASA has taken the solar sail idea past the drawing board and into development and testing. Solar sails are giant, flat sheets of very thin, reflective material supported by an arrangement of lightweight booms or masts. The sails reflect sunlight, which provide the force needed to push a spacecraft through space, without using any fuel.
