[ExI] Luna Ring Solar Power

[giorgio gaviraghi]

-There must be better and affordable ways to solve the energy problem such as;
-increase  PV efficiency from the current 15% to at least 40%.                                                                              - Reduce panel costs of an order of magnitude
-impose for new construction 100% power independency and utilization of green sources
-Give tax  breaks and other incentives for the power system transformation
-Utilize all resources (wind, undersea currents, geothermal etc)
reduce power compsumption with advanced technologies
-redesign trasnportation system to allow green power utilization
These and several other measures can be implemented right now , without waiting decades  in unaffordable and crazy projects that could only increase pollution and create dangerous zones in our planet. As for space development much better ideas , including standardization of components, reduce costs for accessibility, utilization of asteroids and other incentives for private initiatives can be implemented.

Same problem with voltage conversion as Elon Musk felt made SPS too 
inefficient, much longer transmission distance, not geostationary, and 
also requires getting building material far beyond geostationary orbit.

The fundamental security problem is that either the beams are weak 
enough that they are no weapons of mass destruction, and then the 
rectennas are just like much better solar collectors of the same size. 
Or the beams have real oomph, and now you have an orbital death ray 
which means geopolitics gets tricky.

Still, robotic factories on the moon are always robotic factories on the 
moon. The project would both force and enable proper space colonisation.
