very interesting...!
/i guess this is totally related to the pressure it can pulse thru .. .
the magnetic field with the velocity would create a decent voltage
I agree. And the length and diameter of the feedback tubes would have to be tuned to the flow rate velocity to maintain a precise output frequency. It might be better, at first, to build the diode version, without feedback, then use an inverter with the output DC?
If this works well enough, we can get our $300,000 by building and selling these units. No one likes the noise from a piston engine driven generator.
This looks like something which can be 3D printed, using the right kind of ink. Like transformer laminate varnish, a high temperature insulator made from alumina, magnesium oxide (Milk of Magnesia), iron oxide, and sodium silicate (automotive stop leak). Of course, the electrodes would have to be installed manually.
