The panels, which circulate water to remove heat from the air, were deployed in a trial in 2022, though they are not currently in use. Paul argues that such a system could be prohibitively expensive.
Hassan Hemida at the University of Birmingham says Paul’s water-cooling technology is a “good idea,” though it remains to be seen how much heat it…
