*borrowed*from A51, or whatever.

The minimum amount of energy is a number only available in perfect circumstances. Some modes of elevation are more efficient. Some modes are less efficient. It all goes back to fighting against gravity.

Gravity is constantly pulling down at one gee. If your elevational motorvator is boosting you up at 1.001 gee gross then you are wasting most of your energy just to prevent falling back down. If your elevational motorvator is boosting you up at net 10 gee then you are only wasting one gee worth of energy compared to the 11 gee of gross energy expended. Eleven gee minus one gee to null gravity equals 10 gee going up. Get it?

One gee just lets you hover while burning up energy. 1.001 gee burns up one gee to not fall back down leaving you with only 0.001 gee to go up. 11 gee gross burns up one gee to not fall down leaving you 10 gee to go up.

Careful mathematical examination of the situation shows us that the most efficient way of going up is the way that provides the greatest gee acceleration upward. That way the chronic one gee tax paid to the planet gravity becomes less important.

Ok. Bottom line time. it doesn't matter if you go up in a rocket, a flying saucer

*borrowed*from A51, or even an orbit elevator. Whatever is the most efficient way is the most economical, therefore , in the opinion of some bean counters , the best way.

Question: Does the fantasized orbit elevator offer the greatest fantasized acceleration upward and therefore the most efficient way to get into orbit?

Helpful hint:

*Hell no*.
