Not trying to challenge, but can you link to some studies that demonstrates a negative consequence to long term glp-1 agonist use?

How much Delta-V would that take, and how much would they typically have onboard at the start of their life?

And we'll have entirely predictable results from the shift.

Genuine question here, but why not use dogs for this? Is it because dogs might be too heavy and trigger a mine? What is the activation weight of a landmine?

142mj/kg is great, but not if you need a bus size volume to hold 1kg

How much volume does 5kg of hydrogen take up?

How much energy could possibly be stored in one of those containers? Enough to drive a car 100km? (talk about range anxiety...)

I ask because I know that Hydrogen has terrible energy density per unit of volume, even at scary high levels of pressure (Google says 5.6 MJ/L for compressed hydrogen gas at 700 bar pressure). Compare that with gasoline which is 32 MJ/L (To be clear, I'm not advocating for gasoline as storage medium of energy, just showing the contrast).
