  • 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.

  • 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.

  • 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.

  • No.

  • 7 47 is about $300 million.

  • You need two of them for a round trip.

  • 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.

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.
