Hello OU dot com Distinguished Fellows,
Just an observation...
Please#1, ask YouTube with this kinda request : "Low RMP Low Torque PM generators"
(BTW : PM = Permanent Magnet)
You will get a lot of vids showing some guy (apparently easily) hand mowing the axe of a device
that is powering some electrical tool. Not loaded it is true.
Now, please#2, ask the Web about the Power that can be delivered by, saying, a bike champion
(with his 2 legs). You will get a lot of web sites with calculations, charts and graphs.
Please#3, just compare Watts-Wise between the two situations?
IMO, it sounds like that some of the PM generators only need few mechanical power.
Le bonsoir vous sied,
Jean
