[ExI] Article on power sats and laser propulsion

[Keith Henson]

I have a draft version of an article for the JBIS on power sats and
laser propulsion.  It's not for public dissemination.

It has not even been copy edited.  But if you want to read it and
comment, let me know and I will send you a copy.  The whole subject is
being taken just a bit seriously as a way to cope with energy and
carbon.  I spent an hour discussing it at ESTEC recently.
