Not at all. Done all the time. What was deceitful was your implying it was not done.
I “implied” nothing, boy. I stated facts. Your attempted spin is a miserable failure. 1% per day is what you get when you’re dealing with real-world dewars, regardless of cryogen. LHe, LN2, LH2, LOX all in the real world boil off at about the same rate. Your cute little picture of a LH2 tanker doesn’t change that.
Again, you’re being deceptive. Shame on you.
Bye, now.
