*Ariane 5 fuel costs are in the same ballpark as (or better than) the elevator electricity costs once the Edwards inefficiency figures of 2% or worse are factored in. The cost of fabricating the rocket does not account for the remainder of the $25,000 cost. So (at least some) turnaround/launch/capital costs are in there somewhere.

: I've already covered all of this several times, and hate to have to keep covering it. 1) The shuttle and Ariane DO NOT include their capital costs in their launch cost, so it is completely unfair to do so here. I've already demonstrated this to you concerning the shuttle - lookup their turnaround cost (I already quoted it), look up their payload (also quoted), and do the math. 2) If you want me to do the math for the Ariane as well, I will, but I can guarantee you they use the exact same scheme. 3) It's '''not just fuel costs'''. There are tons of cost associated with the turnaround. Why is it hard for you to understand that '''there is a reason that rocket launches cost so much'''? The implication of your argument is that all of the collective brain trust of the USA, USSR, ESA, Chinese, etc, are just fools for not seing this. '''That is not the case'''.
 
: In short, we have a development cost around what the shuttle's development cost was (in modern dollars). We have the same accounting system as the shuttle. The Ariane works similarly. ''What is the problem''? [[User:Rei|Rei]] 18:58, 10 May 2004 (UTC)
