I would like to see a "national public" satellite radio. Pump the National Weather Service and another channel or few with public domain entertainment on it, to get people to buy them (eg. Eton radios) and chuck them in the closet for a severe weather or disaster event.

I understand the science decently, but I don't understand the economic feasibility. I assume if it were feasible, it would have been done by now.

But it seems like something that will become more economically feasible in the near future as space transport progresses.
