But can you eat it ?
If we figure out fusion, everything has the same energy density.
I made kind of the same joke here:
But we have to figure out more then just fusion. Fusion uses the mass defect of light elements while fission uses the mass defect of heavy ones but neither of them achieves converting protons or neutrons into energy completely. Neutrons and protons are never destroyed in fusion or fission.
Need an xkcd bot here immediately.
I always say, the main difference between us and cavemen is energy. It stands to reason that the next monumental jump will require more energy, not the same or less.
I prefer sugar. Hahahahh
My plan is to add batteries to this graph!!
The real question is: Where are the fat-run vehicles at?
There are. You can retro-fit your diesel car to run on old frying oil or fat. My dad wanted to do it for a long time. You'd put a heated fat container into your trunk and connect it to your injection. Just don't forget to switch to diesel some km before reaching your destination or you'll need some external heating to get going again.
