Is the purpose of the table to show that boundary layer control (I assume that means having suction ports around the airship envelope) isn't energy efficient? What is the source?

It's discussing the amount of horsepower needed for an airship at different speeds, with and without boundary layer control. I believe this is from NASA's 1975 "Feasibility Study of Modern Airships: Phase 1, Volume 1". Unfortunately the links I used before to find it seem to be broken.

lol. I can’t say that I’ve ever heard this suggested im any of the clean sheet development meetings I’ve been a part of. Now I feel like I’m missing out.

I miss having zeppelins flying around the SF Bay Area, though somebody (iirc Sergei) had a white one flying out of Moffett in the past year. Airship Ventures got killed off by a 10x price rise in helium.

This is how LLMs got introduced everywhere. My employer created their own GPT thingy, then sent out internal mails asking for help "identifying use cases for customers".
