This is my kind of solar!

Hi all,

I normally diagnose a fast build out of nuclear power, eventually scaling this up to GenIV breeder reactors like the Integral Fast Reactor or eventually the ultimate waste-eating reactor, the Molten Salt Reactor. (The IFR is a GREAT and very safe reactor, but the MSR has passive safety systems that I personally think are even better. EG: No liquid sodium).

But I mentioned solar? Well, this is a futuristic scenario about automation on the moon, and a series of these around the moon could provide a lot of the power they need constructed from local materials. They could also build nuclear, but if automated robots are building this, then it may be easier for them to build a number of these solar towers around the moon and overcome the fortnight night-time that way. But the best bit? Build the solar concentrators in impact craters, and they get the inwards curvature for free.

 

Just whack this…

In one of these…

Again, this is assuming an almost post-scarcity economy with far more sophisticated robot-labour practically for free. In today’s economy, renewables are not going to do the job here on earth, not unless something radical changes in energy storage technology. But in the future? Maybe with a lunar moon robot industry with an output a million times America’s economy today,  maybe we’ll have the sheer robot-labour to build space-based solar power systems that beam microwaves back to receiving stations on earth and get all our power from the sun. Who knows? That’s for our grandchildren and great grandchildren to decide.
