Thorium isn't "pie in the sky", it's very doable (https://spectrum.ieee.org/china-closing-in-on-thorium-nuclear-reactor https://spectrum.ieee.org/china-closing-in-on-thorium-nuclea...). The issue was that thorium was abandoned by the U.S. and other countries, because uranium nuclear reactors (despite their greater dangers) have dual use, and can be used for creating nuclear weapons. Other countries followed the U.S. example, thus we must live with these greater dangers. If not from nuclear accidents or sabotage (or stray bullets), from unfriendly countries having disguised nuclear weapon production programs. Plain and simple, we don't need more nuclear weapons or more nuclear armed countries, as we can destroy this planet several times over. Nor do we need more dangerous nuclear waste or fear of catastrophic accidents. Thorium reactors don't lend themselves to nuclear weapons production, and reduces the waste dangers. And it doesn't have to be thorium, but we can as least build them safer and smarter. Nuclear power can be great for humankind, if we harnessed it more safely, to include using it on our moon, Mars, and beyond. On Earth, thorium is a safer and possible alternative. We need to get over our fossil fuel suicidal addiction, sooner, rather than later. Renewables are great, but its going to take us more time to get where we need to be, so nuclear power can help get us there faster.
