You speak as though you have knowledge of technology. But evidently you don't, if you can't see or don't know the solution. I've been in technology all my life, including registering patents for energy related components in the past.
I write about the solution having researched it now for six years since seeing the global energy problem coming since then during PhD work.
Yet you claim it's impossible with probably zero experience.
If you talk people into following you in your cult then those folk might indeed be doomed.
But outside your cult everyone will just move from the energy of Earth to the energy of the sun like any plant does when it forms leaves, using technology. Just like any creature is born from dependence on the energy of its mother host or egg to the energy of the environment. Anyone not understanding that and seeing it is the most natural thing in the world, doesn't understand what life is. I think it would be an insult to say folk don't understand what life is.
Of course they / we understand.
Don't you?
