    Anyone have a realistic estimation of how much nuclear ressources are know to ne availableandd if humanity as a whole switched toita as the main energy production, how much time can it buy us ? I’m from France, a country with a huge amount of nuclear power, and I don’t know if such a strategy would be viable worldwide, or is it just egoistic to promote it in a nation that have the choice ?

      some numbers about uranium https://phys.org/news/2011-05-nuclear-power-world-energy.html

      Some numbers about thorium https://world-nuclear.org/information-library/current-and-future-generation/thorium.aspx

      There are around 6.3 million tons of thorium around, and it’s estimated that 1 tonne produces roughly 1GWe-yr.

      from Wikipedia :
      In 2011 a group of scientists at the Georgia Institute of Technology assessed thorium-based power as “a 1000+ year solution or a quality low-carbon bridge to truly sustainable energy sources solving a huge portion of mankind’s negative environmental impact.”
