Aerial Recovery DownrangeRecovery proceeds in a manner similar
to the Corona (KH-4) satellite series. A recovery aircraft
loitersdownrange from the launch center, and snags the booster as
it is gliding to its downrange entry point.The aircraft then tows
the glider back to the launch center for release and recovery on a
runway

positioned high. Thismethod of aerial recovery and release was
wellworked out by 1959

Inflatable Optics
Very lightweight optics using thin film elements provide a means
to focus sunlight to very high intensity.This reduces the cost per
watt, and the mass per watt generated on orbit substantially.
Each metric ton on orbit intercepts 67,000 sq
meters of sunlight. Concentrated 20,000x, eachton requires only
33 sq meters of PV area. Theweight of the film dominates
The launcher described here places 200 metrictons into GEO with
recovery of ALLcompon ents . Compl ete recov ery of components
radically reduces costs andshortens time between launch.

300 metric tons on GEO with this technology is
sufficient to intercept 20 square kilometers of solar energy.
This is large enough to generate12 GW of laser energy continuously
for buyersat a cost of 1/30th of a cent per kilowatt-hour.
1,000 satellites each one 5 km in diameter,placed 72 km apart in
GEO provide continuouspower to any point on Earths surface.
