There are some excellent designs for helium and hydrogen storage tanks in the industry. Some gases (He, H2) while cold may be lighter than air. The system uses eight Th rusters of 1N each functioning with inlet pressure of 8 bars. An ingenious way to do that was discovered by Carl von Linde. Typically they are used for handling objects stored in the vapour stage of liquid nitrogen (ranging from -120°C to 190°C). The hydrogen that can be combined into helium is located inside the very hot core of the main sequence star. [72] Many fullerenes containing helium-3 have been reported. With no end to the helium shortage in sight, there are some scary diagnostic and financial implications in the air. However, with as precious as propane is to the railroad, the tanks are often left out in the cold, stored onsite, next to the switches. All helium tanks are portable (take them virtually anywhere, just not on a flight) and disposable - simply throw them out or recycle them. The “right way” to use onboard helium is to store it as cold as possible, run it through a heat exchanger around the engine and introduce hot helium into the propellant tanks. You can get a bag of about 150-200 balloons for $6-8, mylars for $1 or so each, helium tank rental and helium for about $40 in my area, or figure blown-up ballons from a florist or grocery store at $1-2 each for latex and $3-5 for mylars.
