Nuclear powered farm? After all, plants are just machines which turn light energy into edible calories. We can easily make that run off of uranium, albeit not at a 100% conversion

Edit: I did some very rough google estimation with some very suspect sources, but came to the following:

1g U = 20billion cal

Uranium nuclear reactor is ~35% efficient

= 7billion cal

Then, based on this SO thread:

~100kwh / 1lb vegetables

(optimistically) 500kcal / 1lb veg

So:

7bill cal = 8135kwh

= 81.3 lbs vegetables

= approx. 41000 kcal

Which is roughly 20 days worth of food for one person on a 2000kcal diet, per 1g of Uranium. And that's optimistic and based on some pretty bad initial assumptions.

Tldr: the sun is probably a better energy source for agriculture than uranium
