The main bonus point for me is that it is supposedly possible to get rid of "conventional" highly toxic waste in a thorium reactor. For that alone it should be seriously explored. If it could replace planet destroying dirty energy it should be pushed as much as we can.
But... even the cleanest, safest energy form is not capable of undoing terminal degradation that we see happening all over the planet. For that there are no simple solutions.

Feedback on this sent to me:

"Thorium reactors have a much smaller footprint than do either solar or
wind arrays. That is, you get more bang for the amount of land displaced.
Also, thorium supplies have built up vastly in excess of any current use
for the stuff. So it's so cheap now it's virtually an undesirable waste
product."

"There are other, competing Gen IV designs out there now,"

"..and interest is picking up rapidly. So it's certainly time for people
who can work with this technology to get in on the ground floor. Funding
sources like Bill Gates should be all over this stuff. Estimated
development costs for a full-scale pilot project are ballparked at no more
than one billion $$."

"The nice thing about this kind of power is that the fuel cycles, and
re-creates itself. Once you get your reaction started, it only takes tiny
amounts of feed-in to sustain it forever. So we've very nearly arrived at
the point they predicted back in 1946-- where electric power would be so
cheap it wouldn't have to be metered."

Thorium is far from a panacea, unproven and plenty of safety issues.


Why is it not a panacea and what are the safety issues?


It is also, at the end of the day, just another technology based on
extraction.
Dr. Tom Murphy has a great breakdown of nuclear options from a
sustainability perspective here:

and a great discussion of "The Energy Trap", which prevents us from
investing in tomorrow's solutions when today's energy is scarce:

That's not the point. Those problems can and should be solved other ways
but cheap electric energy would still help with this.

No one said that but it still would help.

Thorium might go a long way toward solving our energy needs.
It could help make insulating materials, solar panels and wind energy
devices more affordable for everyone.

Replace conventional/gmo/chemical fertilizer/synthetic pesticide
agriculture with natural agriculture. Stop herbicide application and gmo
crop seed use.


It will need to be much more than reducing our carbon footprints,
