In that link:
> The Earth's rotational kinetic energy is about 10²9 J, and the world uses something like 10²² J/year, so you could power the entire world for millions of years before you'd run out of rotational energy.
(my phone somehow has a ² but not a ^9; the first number is supposed to be 1e29)
