We should consider alternative fusion paths, including the British one using a railgun to accelerate DT pellets. Britain's 'artificial sun' nuclear fusion reactor sets a new world record | Daily Mail Online Why? Because any other path may bring us closer and faster is why? Now, I'd also be asking JC how much longer is his fav, MSR-U235 or MSR-Thorium 232/233? My fix? I'd go absolutely ape shite for solar panels hooked into batteries. Ape poop, for Wind Turbines at far Ocean. Go massively huge for Electric Vehicles and Hybrids in every showroom on the planet. Why? Because the energy is waiting to be harvested, Not because of Climate Change but because I want to the Russian and Chinese war machine against al of us. I see them as the Existential Threat and Climate as the later fear. It this helps with BOTH issues, great! Also-microhydro, also water flow through pipelines, also whatever else you guys recommend! John and company can and should include snide political comments as desired, since everything energy wise is more in Politics with a capital P. Ideas?

I agree with all that except that most of the Laser's energy that hits the Fusion target does not heat the core deuterium and tritium pellet directly, instead it heats an outer layer of a heavy metal like gold or lead and that produces X-rays that heats the deuterium and tritium. With this indirect method you lose a lot of efficiency but it's necessary because the lasers are in the ultraviolet range and when UV light hits a plasma most of the energy accelerates the electrons not the nuclei which is what you want to fuse. Of course it doesn't take long for the energy in the nuclei and the electrons to equalize but it takes longer than the time window you have for fusion to occur which is only about as long as it takes light to move 1 inch. If they could make a laser that worked with a shorter wavelength than ultraviolet it would improve efficiency enormously and you could get by with a much less powerful laser.
