Seems like the OP misspoke. Auragen calls their device a "power generator" or more precisely an "axial flux induction power machine" and it is by no means anything like a "generator" of any conventional type. It appears to be a pancake shaped alternator [sic] that can be bolted up to other machinery.
But calling it a generator
...You might as well say you're buying
a power station. That's just the wrong thing to call it.
