In the same way biofuels are: Technically yes, but still not that great of an idea outside special applications. (One I could imagine would be someone wanting to live completely off grid using filtered frying oil in an old-but-ridiculously-sturdy diesel generator)
Wonder what that would look like the even more extreme case of matter-anti-matter?
By the way, energy density is exactly what you look for in bombs. It says nothing about energy prices per joule. It's also great for nuclear submarines or nuclear powered aircraft carriers. So war, basically. Light from the sun has a pretty low energy density, yet powers live on earth.
The energy density of light from the sun is pretty insane. You can power a lot with 1kg of light
Yep, radiation pressure. Which is a limiting factor for star size too: too big and the radiation pressure gets stronger than the gravity, blows them appart.
