The numbers don't add up. If you can get 21 billion US food calories from total annihilation (which I checked is right), you'd get nowhere near 18 billion food calories from a fusion reaction. Maybe it works if you assume "calories" for the fission reaction means metric calories, since US food calories are metric kilocalories.
I hate the way the word "calorie" ended up with two wildly different definitions.
Yeah, I looked up energy density assuming fast neutron reactor, and it's "only" 7 million US food calories.
US calories are equal to the real metric unit of kilocalories. Maybe the meme above used real calories
