> We need solutions now, and we already have them in mass production: solar panels, wind power generation and battery storage.

This is the one thing I like about Tesla and SpaceX: they solve problems with today's tech.

When I imagined reusable spacecraft, I was dreaming about anti-gravity drives, which just furthered my believe of it being impossible. SpaceX did it on a kerosene rocket, same physics that the Saturn V used decades ago.

We don't need to wait for some Sci-Fi physics to solve this issue. We can go really far with we already have today.
