[s-cars] eRAM info

[Mark Strangways]

It's a very good point to not that neither of these products you mention are
axial fans as is this eRAM device.
It requires a radial type unit to produce any significant pressure. One may
note that when overloaded axial fans overspeed, and draw LESS power, where
as they "real" units would load down the motor and draw many more amps.

Nothing like beating a product to death :)
I hope it's only the ricer crowd that perceives these units as valid
induction units.
