Surely biofuel is the obvious choice for aircraft. You don't even need to make any changes to the planes, existing planes can run on biofuel of suitable quality.

In the country where I live, for a couple of months each year the outside can be as high as 320K which is higher than the inside (thank goodness for sweat).
I suppose you could have a watch strap which works with thermal gradient in either direction, but what happens on days when inside and outside are the same temperature?
Re: "One wonders what good that money could do"
... and the benefits they have brought.
Is your main concern climate change? Yes? Good, it should be! Luckily, jet fuel is just kerosene of high purity, and it can easily be made from vegetable oil (at a slight increase in ticket price, which I am happy to pay).
p.s. I wouldn't suggest biofuels for all vehicles because that would compete with land for food. Ships can use hydrogen, cars can use batteries, trucks can use either batteries or hydrogen, aeroplanes need very high energy density with low storage weight which means hydrocarbons which means biofuel.

Re: On merit?
If Apollo astronauts (and before that, test pilots) had been chosen on merit, by now there would already have been some women on the Moon and this conversation wouldn't be happening.
NASA now has lots of suitable astronauts who have *all* been chosen on merit, some of them are women, so why not pick one of those?
In the words of former NASA Administrator, Michael D. Griffin:
The goal isn't just scientific exploration.
... It's also about extending the range of human habitat out from Earth into the solar system as we go forward in time. ... In the long run a single-planet species will not survive. ... If we humans want to survive for hundreds of thousands or millions of years, we must ultimately populate other planets. Now, today the technology is such that this is barely conceivable. We're in the infancy of it. ... I'm talking about that one day, I don't know when that day is, but there will be more human beings who live off the Earth than on it. We may well have people living on the moon. We may have people living on the moons of Jupiter and other planets. We may have people making habitats on asteroids ... I know that humans will colonize the solar system and one day go beyond.
