No. Because kT is much larger than the orientational energy of proton spins in any reasonable magnetic field, paramagnetic demagnetization is a hopelessly inefficient way to remove heat at room temperature. Also, the kind of internal cooling described is only useful if we want to cool rapidly, which we do not want to do in cryonics because then cells freeze intracellularly (very bad) instead of intercellarly (not as bad). I think Daedalus should go back to school and learn some basic physics, neurobiology, and cryobiology. --- Brian Wowk Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=1478
