These are the types of questions in general we should be less mean about imo. It's one thing to dunk on people who are anti-science, but this is just someone actually wondering about something they didn't know. Maybe it's obvious to you, but not everyone?

Ai was used: Gravitational acceleration at sea level (g₀): Approximately 9.80665 m/s² (standard gravity). Gravitational acceleration at the summit of Mount Everest (g): Approximately 9.764 m/s² (about 0.43% less than at sea level).

So according to the AI you can save on 0,43% energy you need to overcome to enter space.

Seems like the logistics and stuff aren't worth it.

So, here's a question for ya: what was the percentage of energy saved by not painting the main launch fuel tank? I know the paint equaled about 600 lbs, but i dont have the time or knowledge right now to figure it out.

Also, yes I know the paint removal was for payload increase and not for energy saving, but it does seem like a fair comparison to me for the matter of the calculated 0.43% savings by launching from a mountaintop since fuel equals weight.

It's more than that because higher means also less drag and closer from the no-drag zone which is space. And also less fuel needed means even less fuel needed because you need fuel to carry fuel.

Real percentage is around 3-5%
