"The sun's abundant energy, if harvested in space,
could provide a cost-effective way to meet global
power needs in as little as 30 years with seed
money from governments, according to a study
by an international scientific group.

Orbiting power plants capable of collecting solar
energy and beaming it to Earth appear "technically
feasible" within a decade or two based on
technologies now in the laboratory, a study group
of the Paris-headquartered International Academy
of Astronautics said.

Such a project may be able to achieve economic
viability in 30 years or less, it said, without laying
out a road map or proposing a specific architecture."

Nothing new about this. *If someone can come up with a cheap launcher
then they're viable. *If we keep on throwing away a multimillion dollar
rocket on every launch they won't ever be.

William Mook claims to offer cheap reusable launchers.
