design to cost
"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." 
Applications of this methodology includes the dollar-a-gallon gasoline project.
(Recent 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.

- We made this animation of transporting parts to GEO and building a thermal power satellite for a contest. We came in second, a team supported by the Chinese government won. 3000 of these could entirely replace the three cubic miles of oil (equivalent) of fossil fuel the human race uses each year. By the early 2030s if we got on it soon.

Programing 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.
