Cold Capture
Cooling technology that separates helium-3 from ordinary helium, designed to plug into helium liquefaction plants on Earth. It is also the test version of the process Interlune plans to use on the Moon.
Why it matters
Quantum computers need helium-3 to reach near-absolute-zero temperatures, and Earth supply is tiny. Interlune says Cold Capture could triple the current U.S. supply, with no trip to the Moon required.
How the technology works
Every liter of helium contains trace amounts of helium-3. Cold Capture uses cryogenic distillation to separate it, and is designed to plug into existing helium liquefaction plants.
Interlune reports it produced 99% pure helium-3 from Grade A helium.
