I'm talking about converting desert into productive Hydroponics farms.
Today the most critical aspect is producing freshwater to get it done.
The most interesting way to do it is high temperature nuclear.
The heat cycle to generate electricity with high temp source involves cooling down water from well over boiling point down to temps lower than boiling. That means free heat to boil water in huge scale, no penalty for doing so. The cooling is needed anyways.
But the vast majority of current nuclear operates at 350C coolant temps, not high temperature.
Several proposed reactors run anywhere from 450C to 700C, all of them able to dessalinate sea water.
High temp nuclear is also got enough to make hydrogen, amonia, even synthetic methane (natural gas).
When will we study nuclear facts and understand that nuclear kills / hurts orders of magnitude less people than coal, natural gas or oil.
Deepwater horizon killed dozens of people and took the livelyhood of millions of fisherman and tourist industry professionals. Still nuclear gets the bad rap, while oil/gas drilling still allowed.
Coal is estimated to kill about 200k yearly worldwide and 13k yearly in the USA alone.
Natural gas and oil each is estimated to kill over 10k people yearly worldwide.
The whole nuclear power supply chain killed one person in the last few decades, with total cummulative nuclear deaths for all nuclear related accidents of just a few hundred people, while coal is allowed to kill 13000 people EVERY YEAR.
If coal power stations were regulated for their radioactivity emissions like nuclear reactors, they would all be shutdown imediately.
The coal lobby was very forceful to keep its freedom to release deadly toxics and radioactivity almost freely, while nuclear reactors are burdened with insane regulatory costs.
Nuclear doesn't have to be too expensive. It was made too expensive to prevent it from destroying the coal/gas industry.
