Schaeffer Steam Generator

The Schaeffer steam generator is the apparatus documented in a source dossier, catalogued as "dossier 22 — The steam generator" and hosted at [source note 1]. It is attributed to an inventor surnamed Schaeffer (steam generator inventor).

What the device is claimed to be

A steam generator: a device that produces steam, presumably for heat or mechanical power. The newly generated version states this more explicitly as a device that converts water to steam by heat input. This is the extent of the description carried by the available record.

Claimed mechanism

The patent and press article state the mechanism: a motor-driven rotor creates repeated water-hammer shock waves and cavitation in a distended body of water, and the cumulative shocks are said to raise the water's temperature and pressure until it converts to steam. The patent (US #3,791,349) describes alternating centrifugal and vacuum forces in closed-end passageways. The dossier also carries promotional over-unity claims (e.g., a reported 117% Battelle reading) that are assertions by the inventor's associates, not independently established findings. See Steam Generator Claim.

Documented artifacts

The dossier carries eight figure images — 00fig1a through 00fig8, plus 0nr2.jpg — indicating a primarily visual presentation of the apparatus. The newly generated version enumerates the figures as 00fig1a, 00fig2a, 00fig3, 00fig4, 00fig5a, 00fig7, 00fig8, and 0nr2. No captions or figure descriptions are present in the available record.

Status of the description

This is an archive-dossier entry, not a peer-reviewed report or an independent test. The archive compiles inventor submissions and figures without presenting itself as having verified the devices it catalogues. Any claim about the device's operation or performance originates with the dossier's author or submitter and should be attributed accordingly.

What is not known from the supplied material

• The heat source (fuel, electrical, solar, or other).
• The steam output rate, pressure, or temperature.
• The thermal efficiency, if any figure is reported.
• Whether the device was built, demonstrated, or measured.
• Whether the reported over-unity efficiencies (above 100%) can be independently replicated; the testers recommended dynamometer verification.
• The construction details that would distinguish it from a conventional boiler or steam generator.

Evidence status

No measurements, test results, efficiency figures, or independent evaluations are present. The device's function is unverified in the available material. An archive listing is not proof of effectiveness, and a patent (if one is reproduced in the full dossier) would not be proof of effectiveness either.

Why the distinction matters

A conventional steam generator and a device claimed to exceed conventional efficiency limits are different kinds of subject. The first is ordinary engineering, assessable with standard instrumentation. The second is an extraordinary claim requiring calorimetry and independent replication. The supplied evidence does not establish which kind of subject this is, and this page does not assume either.
