. Can the Sun be turned off? :) quote from the Economist Technology Quarterly March 10th 2007:
Environment: Geo-engineering is the direct use of technology to counteract climate change. The idea is highly controversial. ... of all the schemes proposed, the most ambitious (and expensive) idea would be to place a giant sunshade in space at the inner Lagrange point, the position on the line between the Earth and the sun where the combination of centripetal and gravitational forces allows an object to maintain a constant position between the two. If the object is big enough, it could block out enough of the sun's rays to cool the Earth. Roger Angel, an astronomer at the University of Arizona, has suggested assembling a cloud of millions of small reflecting spacecraft less than a metre across at this point , where together they would block out 1.8% of the sun's rays. This is a costly "last option" but Dr Angel has received a grant from NASA to explore the idea. _______________________________________________ Post Messages to: [email protected] Subscription Maintenance: http://leafe.com/mailman/listinfo/profox OT-free version of this list: http://leafe.com/mailman/listinfo/profoxtech Searchable Archive: http://leafe.com/archives/search/profox This message: http://leafe.com/archives/byMID/profox/[EMAIL PROTECTED] ** All postings, unless explicitly stated otherwise, are the opinions of the author, and do not constitute legal or medical advice.
