If you look at, say, the cost of a Falcon nine rocket, which is quite a big rocket, it's about a £1,000,000 of thrust.

程度の副詞

Uh, the, uh and it it is the lowest cost rocket in the world, but and even so, it's it's about 50 to $60 million.

様態の副詞

Um, and but the cost of the fuel and oxygen and so forth is only about $200,000.

So obviously, if we can reuse the rocket, say it 1000 times, then that would make the capital costs of the rocket for launch only about $50,000.

Um, there be maintenance and other things that would factor in the fixed costs and some overhead allocation whatnot, But it would allow for about 100 fold reduction in large costs.

And and this this is a pretty obvious thing.

You think about it as applied to any other mode of transport.

You imagine that if if planes were not reusable, very few people would fly.

Um, and yet I don't think anyone here has paid half a $1,000,000,000 to fly.

Um, and the reason is because those those planes could be used tens of thousands of times and so well, you're really paying for is fuel and pilot costs.

Um, you know, just my sort of incidentals.

 And the capital cost is relatively small.
