The present invention is a fluid power generator with elastic tension gradient strips that move in a serpentine fashion to generate power from fluid flow. Each strip has a tension gradient that decreases going back. This allows steady serpentine movement of the strip to move a coil generator across multiple magnets to generate power. Tensioning tubes keep the strips under tension and attach the strips to a strip support that also supports a magnet holder. The magnet holder keeps the magnets in position within the coil generators so that any serpentine movement of the strip can generate power.

Fluid generator system

A method for quantifying the permeability or conductivity of a conducting material, comprises the steps of providing a circuit including an inductor with a coil and a capacitor connected in parallel to the inductor, the coil having an interior space adapted to enclose the sample material therein; inserting the sample material into the interior space of the coil to completely enclose the sample material therein; resonating the circuit with the capacitor with capacitance C' with the inserted sample material at a resonant frequency f.sub.0 and measuring the resulting impedance, Z' of the circuit; measuring the impedance of the loaded circuit at various frequencies above and below the resonant frequency f.sub.0, and plotting a first bell-shaped curve from the measured impedances against frequencies; resonating the circuit with the capacitor with capacitance C' at a resonant frequency f.sub.x with the sample material removed from the coil and measuring the resulting impedance, Z.sub.0 ; measuring the impedance of the empty circuit at various frequencies above and below the resonant frequency f.sub.x, and plotting a second bell-shaped curve of the measured impedances against frequencies; and determining the conductivity or permeability of the sample material from the first and second bell-shaped curves.
