The US National Ignition Facility has achieved even higher energy yields since breaking even for the first time in 2022, but a practical fusion reactor is still a long way off
Basically, the idea is to build orbital solar farms (where is always sunny), then beam the energy produced back to the ground with microwave transmitters and ground recievers. It’s technically feasible, unlike fusion we have all the technology needed to do it right now. However, it’s cost and resource prohibitive. The US government studied building such a system in the 1970-80’s after the energy crisis. We could do it, but building it would take a generation to get running and about double the US’s current military annual budget. Launch costs are coming down since then, but the industrialization of space and the moon will take generations and would need to be an international effort to have any chance of success.

You know, for a bunch of people who crave power, politicians sure don’t seem too keen on harnessing it.
