According to my calculations, roughly 1120 years:
(surely this simplifies further but I'm not that good at maths).
So all the known uranium in the sea could be good for one millenium
of 1% growth, and then it's "lights out" (that's the scary part -
imagine what sort of hi-tech society would exist after 1000 years of
growth, and then plunge them into energy poverty!!). And to think of
the mind-boggling technological advances and infrastructure that
would need to be made to make even a small fraction of that uranium
Why did Lightfoot oppose renewables again?
