yet you exclude sunlight: curious.
- siegfried-en 6y agoYou can't really measure solar energy in weight, right?
- freeflight 6y agoWith some creative math, and as long as you don't care about the actual practicality of the resulting metric, you can measure anything in everything.

Sunlight is the consequence of the sun's nuclear reactions. So fusion nuclear energy might be comparable, but until then, fission is as close as we get.
