A futuristic scheme to collect solar energy on satellites and beam it to Earth has gained a large supporter in the US military. A report released yesterday by the National Security Space Office recommends that the US government sponsor projects to demonstrate solar-power-generating satellites and provide financial incentives for further private development of the technology.

And some good thoughts in reply
I don't believe its practical. The technological idea is fabulous, but to cripple a country using it, a simple missle would eliminate it, and bring the energy matrix down. We can't go that direction with the money it would take to put it place, unless the WHOLE planet was on board with it.
Money the planet is spending on war machines would be better spent on energy and food and water collection technologies. I'm wondering why we aren't trying to collect rain water in the ultra rainy areas of the midwest and send it to the arrid areas of the country. Cisterns should be the biggest money investments around. If for nothing else than to filter rainwater for drinking water. Instead, we watch it drain off into the gulf. I really think we should follow the rain for the water supplies that are dwindling. It will be an issue. Sooner or later we'll have water collection infrastructure in place everywhere like we should also have solar and wind collection everywhere. Spend the money on it now, and it will pay us back big time in ten years. Build it out of the right materials and it will work for decades.
Maybe I'm just a stupid city boy 'from' Los Angeles and don't know anything of any use, but I'm thinking there is a way to turn this world effort around.

Science fiction to reality: Space-based solar power
by Geoffrey Ozin | Oct 11, 2022
With climate change, the weaponization of energy, lower satellite launch costs, incentives to harness space-based solar power are on the horizon.
[Space-Based Solar Power involves harvesting sunlight from Earth orbit then beaming it down to the surface where it is needed.]
If the time to develop nuclear fusion technology is too long to save humanity from the looming effects of energy starvation, does there exist an alternative power source on the horizon?
Sounds like the science fiction world imagined by Isaac Asimov whose story Reason, published in 1941, foresaw a solar-powered satellite transmitting microwaves to an Earth-based antennae that converted microwave energy into electricity.
Asimov was possibly inspired by the prescience of space travel clairvoyant and Russian theorist Konstantin Tsiolkovsky. In 1923, he forecasted the beaming of concentrated sunlight from space by orbiting mirrors to provide pollution-free heat for a myriad of energy-demanding applications on Earth.
45 years later, NASA engineer Peter Glaser invented a solar-powered satellite. For this, he was granted a patent in 1973 that claimed transmission of microwave-generated power to “rectenna” receivers on Earth. The feasibility of this idea was founded upon the 1964 wireless power transmission research of US electrical engineer, William C. Brown.
These pioneers spawned an incredibly active field of science and engineering whose objective was to harness space-based solar power. This endeavor was launched in the 1970s with extensive research on solar-powered satellites by NASA, the US Department of Energy, and in 1979, the European Space Agency.
At a time when the economics of operating a space-based energy technology system seemed unattractive, today, with the existential threats of climate change, the weaponization of energy, lower satellite launch costs, as well as impressive advances in solar collection and concentration optics, as well as wireless power transmission for powering transportation and charging devices, the incentives for rising to this challenge have greatly improved.
Nowadays, the technological validity and economic viability of harnessing an unlimited supply of sustainable energy from solar power beamed wirelessly from space have been evaluated and are looking much more appealing. Evidence is growing from a number of solar satellite demonstrations, such as that launched by the US Naval Research Laboratory in 2020 designed to evaluate the feasibility of the technology. Other missions in the pipeline include those from Europe, UK, China, and Japan.
Now that all the technology needed for harvesting solar power on Earth from satellites exist and have been well tested, we can begin to imagine — in the not-too-distant future — a world in which the vision of Asimov, Tsiolkovsky, and Glaser includes a forever-free, 24-7 available, sustainable electricity source that is reduced to practice.
Of course, nothing is forever when it comes to the 2nd law of thermodynamics, although with the Sun — a burning ball of fuel that will run out one day when it turns into a red dwarf — it seems like forever from the perspective of the human timescale.
In such a utopian world continuously powered by the free power of the Sun, all our worries and cares about greenhouse gas-induced global warming and deleterious climate change would just evaporate into space!

Could such a utopian world in which 15 years ago the ever-optimistic and idealist, far from "just a stupid city boy 'from' Los Angeles" bagwa-john said it would have to be a whole planet effort. Could there be a time when the selfish ultra-nativist strongmen and wannabes of today are no longer.
We can only hope there may be for the better educated and more inclusive children of the future.
