Time to get on the stump..

Hi Darel,

Thank you for the terrific website
(http://www.sspi.gatech.edu/). I've been looking for
this info for myself for a while now and this has
given me all the missing parts.

My company (Gravitational Concepts Unlimited) is
currently researching Low Cost Electro-Magnet Launch
and a "Space Gas Station". Problem is that the Low
Cost Electro-Magnet Launch is only low cost to launch,
but very high cost to build. In order to build it we
would need to be assured of customers using it enough
to pay for it's construction.

In my work on the "Space Gas Station", I've found a
new material that you might be interested in: "Diamond
Thermionic Electric Generators that gets 60%(did I
copy that right?) efficiency when powered by 100X Suns
(from inflatable reflective solar collector)". - given
to me by Phil Chapman, (www.transformspace.com).
Later I found sources that say over 90% of the Carnot
efficiency.

regards,

Dave Handwerk
