Their advertised "limitations" of conventional mills, tho, is misleading
- noise, vibration, bird kill? Noise is caused by vibration that is
overcome by proper balancing and maintenance of the equipment. I've been
by many a mill and not heard hardly a thing. I guarantee you - soon as
some bird-crap builds up on this thing, it's going to vibrate and rattle
like mad. Bird-kill? Show me dead birds from conventional mills. Can't?
Probably because it's very rare and more birds are killed by cars and
windows and snot-nosed brats with bb-guns than all the mills combined.
Axial flux mills don't cut out at high speeds either - they fold to
reduce their wind-exposure but then they just keep on spinning so
there's no loss of power. 40-watts at 28mph winds? Where do you find
constant 28mph winds? Especially near ground level that they seem to be
preferring? And 40-watts will barely start up a couple of CFL's. No
high-elevation mounting towers? What, they take advantage of red-neck
farts at ground level? All the good wind is up there. Below the
tree-line and roof-line you have too much disturbance for any of the
wind to be useful. Can be mounted on top of buildings? Sure - turn your
house into a resonator. "Almost no vibration" doesn't mean "no
vibration" and that thing will make your house sing. So far this
particular item is vaporware and I hope it stays that way. It's been
demonstrated that vertical mills simply do not harness appreciable
percentages of power from the wind in comparison to conventional mills.
Stick with what works.
