In a recent conversation on the Steorn Forums Al gives more information on the performance of the device. The OCAL or WhipMag (it has many names) is alleged to have sustained motion for 7 hours and 26 minutes before Al stopped it manually. Additionally there have been separate reports from an SPDC member that a replication effort he tried has went 20 seconds at constant speed.
How long it would have went on beyond that is anyon'e guess. Below are extracts of conversations from the forum.
alsetalokin: I started it at 02:14
It is pretty noisy with the bearings chattering and growling, but I think I might be able to sleep.
then posting later he said......
alsetalokin: Shut down by stopping stator mag at about 09:43
RPM just before shutdown: Rotor 1257, Stator 5030
Al's sleep time = 07 hrs. 26 min.
