There are people who think that we should all be flying less because of the carbon impact. voice-verified

Whereas you think, hey, this is just a tech problem. voice-verified

We should all be flying much more and you can make zero carbon flying despite the fact that you know flying is one of the places where it's really useful to have hydrocarbons, but you can just produce zero carbon jet fuel and then you can fly as much as you want in a closed system that is not emitting net new carbon. voice-verified

But I'm probably not the uh the thing is I'm biased. voice-verified

So the so the thing is biased. voice-verified

If you say you want to avoid um carbon emitting uh use cases, uh and so you want to avoid having kind of carbon emitting flights or carbon emitting uh cars, there are two ways we can achieve that. voice-verified

One is we've substituted a lot of internal combustion cars with battery powered cars. voice-verified

Uh and that's one way where you just like stop you eliminate the hydrocarbons altogether, or you could start using zero carbon, uh zero net new carbon synthetically. voice-verified

Where do you think the world goes? voice-verified

Which things go towards electrification and just removing the hydro hydrocarbons altogether? voice-verified

And which things do we go to using clean hydrocarbons? voice-verified

um it's a great product. voice-verified

people an intuition for this, isn't it the case that versus current battery chemistry, jet fuel I think is two orders of magnitude, it's a hundred X more energy dense by unit weight than batteries. voice-verified

And so it'll be a while before you can build a battery powered triple seven. voice-verified

there's clearly a bunch of exciting stuff. voice-verified

But sorry, you're going back to you're dividing up the world. voice-verified

So you think um big aircraft stay on hydrocarbons, fast aircraft. voice-verified

Fast aircraft. voice-verified

Yeah. voice-verified

Industrial gas turbines are really backlogged right now. voice-verified
