Space Ring
Just when you thought you've heard the bizarre, comes this little gem. A group of scientists have come up with a way of battling global climate change caused by heating up of the planet due to greenhouse gases. Their suggestion would cost somewhere between $6 to $500 trillion dollars, and calls for a dramatic effort to control the planet's climate. Their suggestion is for a space ring to be constructed around the planet , which would reflect just 1.6% of solar radiation, but be enough to overcome the slight rise in global temperatures. The ring could be constructed of small particles shepherded by spacecraft -- or small spacecrafts connected in orbit. The ring would be erected around the equator, providing shade primarily to where the planet is the hottest. If the particle solution is used, the materials could come from mining the Moon. A side effect of the ring would be the nightly illumination. We'd be able to see reflected sunlight, similar to the Moon's, at ...
