Submission + - Laser Treatment for Earth-bound Asteroids (bbc.com)

arisvega writes: A recent publication (for the math-versed) proposing the deployment of a Solar-powered, space-borne fleet of LASER cannons that would deflect Earth-bound asteroids caught the attention of international news agencies.

Do you think this ambition can in reasonable time turn into a fair-priced, life-saving (or indeed Biosphere-saving!) project, that will be to the benefit of all mankind? How threatened would you feel from the possibility of this proposed array being hijacked by extremely depraved individuals, ones capable or guilty of great crimes? And, are you not glad that now someone has published a paper on it, so Megacorp cannot 'patent' this Earth-saving idea?
