If she’s talking about hydrogen, yes.

We have to stop burning stuff. It’s really that simple.

She was also talking about carbon capture and hydrogen. Two thermodynamically improbable technologies.

Fantasy politics for the short term.

I'm sure I remember a few months back a plane doing a long journey (UK-US?) on sustainable fuel, but interviews at the time sounded like it wasn't quite the brilliant solution we're looking for

I mean there are two issues as I understand it - synthetic hydrocarbons only make sense at all if you’re making them using genuinely surplus zero-carbon energy, otherwise you’re burning fossil fuels to make fake fossil fuels. Also you’re still burning hydrocarbons in the upper atmosphere.

That is also my understanding.

It's a giant rubber band!

My brother's an aerospace engineer with Rolls Royce. Yes, it's pie in the literal sky. It does not exist.

That was my understanding (I have family in aerospace eng.)
