I'm currently in a discussion with a chemist that has a way of
preparing baloons that would prolong the flight-time by up to 25
times. I think that exploring every aspect of the "baloon-track" is
good, since the problems of powering a thingy into orbit is far more
complicated. It is also alot more expensive and difficult to test.
Lets learn how to crawl, before you learn how to walk.
Sending a site into orbit is offcourse alot more StarWars - but I have
the feeling that it will fail because its a too large problem to start
However - learning from this project will open doors...
Come up with a solution for the baloon and we are in a different
situation. I'll post the discussion with the chemist later if it leads
