Well, let’s see… Cars powered by Thorium reactors would have to be about half as big big as a regular nuclear powered submarine, plus the roadways to deal with them, and the nuclear mess to clean up after every accident. Nuclear powered energy independent house…needs about half of a nuclear submarine, just for the power supply.
If they were even as capable as a nuclear submarine powerplant, there would be off-grid factories using them, at the very least.
Sorry, they can be safer than the crap we already use, but they are still too large to do what was claimed, in wiping out fossil fuels.
Even Tesla’s new solar roofing has to have proper solar orientation, to be effective. There are limits to the physical processes of both, that make them incapable of being just an ordinary, everyday, every household solution.
People talk about how ‘overcrowded’ the planet is, yet is would be possible to put every household on a small self-sufficient homestead, in an area about the size of Texas, and restore the rest of the planet to native habitat. Even better, move all housing to areas that make for poor agriculture, convert a sufficient area to sustainable agriculture practices, and restore that vast majority of the planet to natural habitat.
HOWEVER, people are just too ornery to make such an effective solution work.
