As some of you know, I have been working off and on for forty years on
getting the cost to GEO down to where power satellites can undercut
coal.
Currently working on a thermal power satellite design that looks to
come in at 32,500 tons and puts out 5 GWe at the rectenna bus bars.
To undercut coal, the total cost can't exceed $2.4 B/GW. For 6.5
kg/kW, the cost to get the parts to GEO can't exceed $200/kg. Between
Skylon at more than 10,000 flights per year and an old proposal by
William Brown, it looks like that can be done.
It's here http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=7046244
for those who can get through the pay wall. If not, there is a copy
here:

Off topic, but some of you may find it amusing.
