AirJoule could matter far more if its technology works at scale: it uses waste heat to pull moisture from air, producing water and making cooling cheaper for AI data centers. Early tests show up to about 40% energy savings versus desiccant wheels, though this is unproven at scale. It has run data center pilots, works with GE Vernova, BASF and Carrier, and has $35M of cash and no debt, enough through 2027. Meaningful revenue is not expected until 2027, and many firms never get past pilots. x.com
