How do you calculate the lift generated by hydrogen, helium, or
(theoretically) a vacuum in a balloon (probably mylar)? How high
could such balloons rise, given an ideal situation and a standard
mylar or similar balloon material? What difference does a hot gas
make over a cold gas? What other gases could provide lift in our
atmosphere (i.e. are lighter than air)?
