[Space] Spacebridge micro-satellite

Well, a number of people start off with suggesting launch opportunities we
could piggy back off of and. using existing tech to launch our payload.  The
question that really needs to be considered is what do we want to
accomplish.  Do we want to make a payload?  Do we want to mess around with
our own way to get it there.

I haven't really heard any discussions on things we're particularly excited
about for the payload (although there does seem to be some interest in
putting together _something_).  I've heard a lot of discussion on
interesting things we could do with balloons and launch stuff.

Yes, it'll probably be a lot more expensive to mess around with getting our
own stuff to the edge of space, but it seems to me that we should do what we
have a clear interest in rather than what would be cheapest or easiest, no?

I myself am interested in hight altitude power generation.  It seems to me
there's a lot of energy up there and if we're going to keep anything aloft
for any period of time, we'd need more power than what we can load it up
with at launch.  Actually having power available would also facilitate
extremely useful things like navigation systems.

Getting to the bottom of the hill is convenient. The view from the top of
the hill is stunning. Where would you choose to live?
