I was wondering. We all know nuclear weapons are dirty, dirty weapons. I was thinking that a good weapon would be a magnifying lense. Sounds a little odd, but read on. Many young kids use these devices to barbeque ant hills. Why not put much larger magnifying lenses into space? There could be a purpolsion system onboard to angle it sideways to the perspective of the earth and the sun when it isn't in use, and if a global war broke out, it could be moved into the desired place and turned accordingly. Well, I am against weapons of mass destructions anyways, but wouldn't this be equally as destructive, minus the radiation? One problem I have thought of with this concept is burning the atmosphere wherever the device is used. Thoughts?
