| That sounds like a very clever idea, though I wonder about the feasibility of such a device, and who exactly would fund its design, development, and manufacture. I do think it is a pretty cool idea, but as most things in life, it sounds like an expensive endeavor.
My 2 cents.

Hi, All Just thinking aloud here, I visited a local foundry yesterday to collect some feet for a bath-tub which I had made, and the owner was showing me around his shop …. One thing which caught my eye was an impeller he is currently building a mould for – it is for pumping air into one of his furnaces, and this got me thinking on the way home …. If an impeller were to be cast for this air-induction/super-charging application, and was tied-in to the e-shaft (key-way or similar) would it work to have a suitable magnet cast-in to the periphery of the impeller, so that two coils could be mounted, 180 degrees apart, to provide ‘magneto-type’ spark to one set of plugs – one coil per rotor at 180* for a 2-rotor, and 120* for a 3-rotor – this sounds, to me, so simple that I am surprised nobody has done it before – how good would it be to have a completely battery-independent ignition system for amateur-built aircraft ? … maybe I should shaddup, & return to lurking … Charles
