I already explained the problems with your idea.Yes, it can take energy from humans, if they willingly allow it.
Well I would also agree, but it should be noted that the Genki Dama seems to have a special property to kill evil beings, so even if it wasn't that powerful in terms of physical destructiveness, it could still do much more damage to someone evil than would be suggested by its explosive effects. On the flip side, it doesn't work against people who aren't evil.
Yeah, and Tree of Might was a pretty good movie.
I agree with your explanation, if is a way to explain it, what Goku absorbs is ki, that in DB is latent power, energy, etc. and he transform it in a spiritual attack with the power of what he absorb, Is unknown because Toriyama didn’t care in quantifications
I was reading about human energy, and I found that a quiet human produce 100 joules of heat average, is an interesting subject, we can produce more heat than the core of the sun by far.
With respect to the subject that only evil hearts are affected by genkidama, thereare 2 contradictions, before Goku receive energy from the Namek Dragon, The Kid Buu reject the Spirit Bomb and Goku was about to be destroy by it, also in his training, Goku destroy a brick that has no soul, so I think the reason that explain why Gohan did not die by the genkidama, because he can control ki, other is a plop device in favour of the history.
