No, that is not something we wish to happen!
Fifteen years ago I designed a wind generator
for my sailboat. I had a casting made, actually 12 of them. I designed a stationary armature with a rotating field consisting of custom neodymium iron boron magnets I had manufactured in China
. The product had a 4 blade, 5' diameter propeller
and a maximum output of around 12 amperes in 20+K wind
My intent was to manufacture and sell them. I looked forward to selling many. One night I had a nighmare, someone could get killed with that blade!!! And no, it makes no sense to put a ring shield around a large blade, even that would not prevent physical harm. I gave up the idea completely! I was at risk of losing eveything I owned then and in the future.
Liability laws always seem to benefit those who injure themselves. Even if the instructions clearly state how high the rotor must be to avoid injury, somebody, somehow will always get it wrong.
There is a belief in this litigious country of ours, "that no mater what happens to anyone, it must be some one else's fault."
Lets see how long it takes this accident
to generate a lawsuit.
