I guess in the end, it always boil down to money, or the lack of it.
Creating such systems will not be cheap, as will as the maintenance and the labor for it.
We can simply ignore the threat, of an annual 100ton debris falling on Earth, hoping for the best, or find cheaper but efficient practical ways to
deal with it.
Currently, Norad, Nasa and other space observation installations in richer or insecure nations electronically track the globe daily for rocket
launches, satellites and high altitude aircrafts. Big rocks can be tracked as well, but unfortunately, it is the 10ton rocks that can level 6 cities
at one go that cannot currently be tracked.
Our space rock threat is thus not big rocks, but the small and fast untrackable ones such as those which hit Siberia few days ago.
Perhaps, universities around the world can try to get their science students to come with ideas on how to deal with those small tracks. I am sure out
of the many thousands of graduating students, some of them are bound to have a brilliant idea of 2 for some cheap and effective measures.
Anway, its time we look towards space for resources, as at the rate of our consumption, pretty soon resources will be far costly to mine on Earth, and
planets/asteroids may be cheaper, the way expensive oil had lead to fracking being a cheaper alternative.
And the best place to look for ideas are from our young, whom are free from funding worries that researchers often have to face, as University
fundings comes from both the govt/People and charitable organisations, which can be put to good use rather than to repeat experiments or studies just
to get a degree or Phd. At least that would be a direction that has more relavance for mankind.
