Do you even realize how much energy is needed to produce significant amounts of hydrogen and then compressing it to a useful pressure? FOB solar isn’t going to cut it. Decentralized H2 production isn’t a viable thing without fossil fuels or a working power grid.
Uh, this is gonna get NCD all hot and bothered!
I just tell people to please use headphones or turn their whatever to silent. I’ve only once had a guy react not so nicely to that.
The theoretical energy density assumes no cryogenic tanks, no plumbing, and no fuel cells. Also the production, storage, and transfer of Hydrogen as a fuel is INCREDIBLY inefficient.
Except some species target bee hives and kill all the fuzzballs to get to the honey.
Flat Head screws had their raison d’être 100 years age, because they were easy to manufacture. Nowadays though there are no excuses for using them anymore.
