"Design to cost is a management strategy and supporting methodologies to achieve an affordable product by treating target cost as an independent design parameter that needs to be achieved during the development of a product." [1]
Applications of this methodology include the dollar-a-gallon gasoline project.
(Recent articles, video and ppt links)
Started soon and pushed hard, this project could end the use of fossil fuels short of 440 ppm and bring the level down as much as is wanted. It would lower the cost of energy at the same time.
Paul Allen's StratoLaunch vehicle used to ferry Skylons from factory to equatorial launch sites
Skylon Ozone damage (NOx)
Some of you know that in 2014 I asked people at NOAA to look into the potential ozone damage from up to a million Skylon flights per year. There is no point in solving the carbon and energy problem with power satellites if the cost is a billion cases of skin cancer.
They put a lot of effort into modeling the problem, hundreds of hours of supercomputer time on the models, writing a paper and getting it through peer review. I really appreciate what they did.
The paper is available online at
https://agupubs.onlinelibrary.wiley.com/doi/full/10.1002/2016EF000399
.
Short answer: the damage to the ozone is not a showstopper for the hydrogen burning Skylon.

Multi GW thermal radiator to get rid of waste heat from the lasers.
Programming to keep the laser beam from intersecting with satellites in lower orbits.
If anyone wants to scope out one of the problems with building power satellites via laser propulsion, I would sure appreciate it. The problem is the big laser beam that provides the energy needed to heat hydrogen for the propulsion into space. It tracks along the equator for about 4000 km accelerating a reusable vehicle into LEO, and does this 3 times an hour. It's not acceptable for the beam to intersect tens of millions of dollars worth of global positioning satellite with 20 MW/m^2.
Either the beam has to be briefly cut off to allow a satellite to pass through, or the acceleration and timing needs to be adjusted to avoid such intersections of the beam and working satellites. The problem isn't that different from the problem of satellites running into a space elevator cable.
Listing of launch sites with consideration for the initial power coming from the Earth.
