"DE-STAR is designed to harness some of the power of the Sun and convert it into a massive phased array of laser beams that can destroy, or evaporate, asteroids posing a potential threat to Earth. It is equally capable of changing an asteroid's orbit - deflecting it away from Earth, or into the Sun - and may also prove to be a valuable tool for assessing an asteroid's composition, enabling lucrative, rare-element mining." Full Article: http://www.hindustantimes.com/HTNext/LifeAndUniverse/Sun-powered-lasers-may-vaporise-asteroids-protect-Earth/Article1-1014374.aspx this reminds of a scene in one of the star wars movies where they shot a laser into a planet and destroyed it. What do you think? |

that is cool. but to build the thing would probably be very expensive. may be cheaper to just use some of our outdated nukes and blow them up. |

Of course it can point towards Earth as easily as at objects coming towards it. Call me cynical. |
