Peak everything is approaching and we don't have enough jobs.
What do we do?
Use machines to create jobs...
I believe the EROEI for solar is around 10. If we "put aside" 3 parts of that toward exponential growth of automated solar factories, ALL the problems would be solved.
Advanced machine automation could create about 600,000 square miles of installation jobs, globally! That's assuming solar power alone is used to power 10 billion people at the western standard (including not having to waste energy on spinning generators and end use efficiencies such as electric cars, more insulation, led lights, etc).
Obviously, people would charge too much to make enough arrays to cover 1% of Earth's landspace, but they wouldn't charge too much to install them!
I did some basic and simple math (which is about all I know) and came to the conclusion that "normal" solar panels would require 2% of Earth's land space AND would cause negative albedo... it emits more infrared than the land it covers. I realize that we could power 100 times the people on clean energy... if it did not waste (or emit) heat in the process.
Nuclear, if done with a molten fuel (and without dangerous high pressures) could really blow away solar... in EROEI. Such "better and safer nuclear" still would waste about 55% of the energy as heat (and generate waste heat from the decay of nasty stuff for some 300 years).
Gallium arsenide solar dishes concentrates such high temps that the laws of physics states that it (the unused 70% of sunlight) can re-emit in the visible, and less infrared, which can be reflected back toward the sun unimpeded by the infrared absorbing (and re-emitting) CO2 and other GHG's.
I demand this solution!
It takes care of unemployment, global warming and excess heat (which is about 1% of fossil fueled forcings). These 2 axis solar dishes need no thermodynamics, produces no GHG's (except at first stage during manufacture) and even reflects some of the excess heat byproduct. This means that global population could, convievably grow well beyond what is presently imagined, to many tens of billions, living off of machine (and home made) hydrophonics and "grown meat".
There should be no reason to not be able to build automated battery factories, as well as for all the parts of the solar dish.
