is it possible the last gentleman was saying the hydrogen was super heated to a nuclear reaction and directed for thrust ...thereby transforming a plain propellant into a propellant/fuel ?
boil off speed/velocity/realative time? ..of "water" is largely determined by atmospheric "Pressure" as well as tempeture ..not so heavier elements as on the outer planets..which like our own compressed gases boil off at relative low "Pressures/Tempeture" (out of the container/can) ...c-ya
DUDE ...Venus is not a water vapor atmosphere ...its HEAVY boiling acid gasses are way too heavy to be effected by the process we speak of... you want to see that solar wind blow-off look at mercury ...nuff said
H2o/mars?
HMM a very convoluted subject...there are many shcools of thought on this and they are all, just theories ..but a few things to consider are: a large cataclysm befell the planet long ago,such as a heat source so strong it blew the atmosphere off (planets collide?) with the cooling...
