New yahoo group: lowcosttospace

Hello, I have posted here a few times and some of you might recognize
me. I have started a new group called Low Cost To Space. The name is
pretty much self-explanatory:

Low Cost To Space

Human exploration and settlement of space has progressed slowly, ever since the mid 1970's. The reason why: the huge cost of getting anything into space--about $10,000 per kilogram.

This group discusses different technologies for getting people and cargo into space, at potentially vastly lower costs than current ones.

Any and all possible methods can be discussed. They must be within the boundaries of known science, however (this is not a group for discussing alternative physics based technologies and theories).

If you are interested, please join.
