For this reason most wind tunnels operate intermittently using energy stored in high-pressure tanks.
At least on Zalit they had lived in high-pressure spherical tanks which were filled with methane.
I have an old high-pressure tank at my place, that would get you the whole way.
The platoon leader keyed his central weapons board, and high-pressure tanks, emplaced at the hill's base, sprayed into life.
The gas is stored in several high-pressure tanks under the rear of the vehicle.
"He's pumping some of the helium back into the high-pressure tanks to cut the lift," I said into her ear.
Storage as a gas typically requires high-pressure tanks (5000-10,000 psi tank pressure).
It was most likely a pressure-reduction valve releasing air from a high-pressure tank to maintain a lower pressure somewhere else.
When the gauge reached the danger mark I released fresh oxygen from the high-pressure tank into his regenerator circuit.
All high-pressure tanks are metal and seamless.
