> Then they start talking about things that currently cannot account for even 0.001% of our global energy storage needs
Not currently, but who's to say that it won't be possible to scale out manufacturing capacity for the technologies that we'll need? A couple of decades ago, EV production and EV charging networks basically did not exist, so by the same reasoning you'd be saying that it wouldn't be possible to have them.
But look where we are now.
Furthermore, the space of possibly feasible ideas/technologies is gigantic, you're just lacking in imagination. For starters, we haven't yet explored my idea:
1. Turn gym equipment into energy-generating devices.
2. Mandatory gym time by law for every able-bodied man and woman.
Solve the renewable problem and health/obesity problems at the same time. Boom.
If that's not enough:
3. Mandatory gym time also for pets and farm animals.
4. Install wind turbines on airplanes (deployed only when descending).
5. Install boat engines on floating wind turbines and remotely navigate them into hurricanes (imagine all that wind energy we're currently wasting!).
6. And if that's not enough, let's start constructing a Dyson sphere already. We already know how to build space rockets. So what's taking us so long? Less talk, more action.
And that's just the ideas that I, a layman, have come up with. So imagine what the experts could think of.
