I an amazed, 2021 nasa budget if the internet doesn't lie to me was 25b

Imho the money spent in both space and fusion is worthy but this gives an idea of how little is 35b adjusted for inflation spent in fusion spanning 68 years compared to another endeavours

one wonders what fusion would achieve if they did a Manhattan project of it or sacrifice money as they did like at the beginning of the space exploration and moon landings

> What you are showing here is probably a decline in average temperature.

While I agree relative humidity has its flaws, this isn't true. Assuming OP is in the northern hemisphere, temperature is indeed dropping. However, cold air stores less water, so the relative humidity for the same amount of water would go up, not down.

If OP is in the southern hemisphere, then I would question if what they are plotting is actually an improvement due to the remedial works or just a rise in temperature.

> higher energy density

Higher energy density per mass, but much much lower energy density per volume, which really matters if you're building a vehicle. There's only so much room inside an airplane for fuel tanks.

But regardless, whether it's gasoline or hydrogen, the point is that with enough free energy you can synthesize any fuel you need.
