Thermoacoustic-catalytic system for cooling and transforming cryogenic hydrogen
Unmet Need: Efficient hydrogen cooling and spin conversion
Hydrogen is one of the most promising fuels for the future clean economy, as it does not produce harmful emissions and as a liquid, hydrogen is one of the most energy-dense carriers. However, conventional liquefaction and cooling systems for cryogenic hydrogen involve a number of moving parts...

Origami structure as an expulsion bladder for a rocket tank
Challenge: Supply of vapor-free cryogenic liquid propellant in a rocket tank
The key to propellant transfer in microgravity is the propellant management device (PMD), which ensures that vapor-free propellant is supplied from a source tank (e.g. a fuel depot) to a receiver tank or engine. Failure to do so for engines will result in combustion inefficiencies...

Vortex tube lined with magnets for liquid oxygen separation
Unmet Need: Alternative method for the separation and liquefaction of gases
A widely used method for the liquefaction of gas includes compression of gas in a compressor, preliminary cooling in a heat exchanger and further cooling it in an expander with subsequent expansion of the gas through a throttle valve to cause cooling and condensation. Subsequently...
