Would this be a viable patent claim?
(OP)
"An electric rotating machine, which can be operated as either a motor or generator, utilizes material exhibiting a Hall effect to replace the normal slip rings or mechanical commutation devices. Preferably, a slab of Hall effect material is curved to extend circumferentially around the rotor between the rotor and stator, and the rotor is adapted to create a magnetic field. When used as a motor, a source of electrical power is connected to the Hall effect material to cause a primary current to flow therein. The combination of the rotor magnetic field and the primary current flowing in the Hall effect material produces a Hall effect current which creates a torque on the rotor causing it to rotate. When used as a generator, the rotor is rotated and induces a primary current to flow in the Hall effect material. The combination of the rotor magnetic field and the induced primary current produces a Hall effect voltage and current that can be connected to power an electrical load."
Could this be the abstract for a successful patent application?
It would be very interesting to hear your views. My view is chrystal clear...

RE: Would this be a viable patent claim?
The actual claims would have to be described to make the final judgement, since an invention must show an improvement over prior art.
That's the primary flaw of the abstract, in that it does not describe why the invention is necessary or better.

RE: Would this be a viable patent claim?
The biggest variable is how effective is the search for "prior art". Or, in other words, is this really a new idea or has it been thought of before and, especially, has a patent for the concept be applied for previously.
The record in recent years with the US Patent Office is that the search for prior art is superficial at best so the chances of a patent being awarded are pretty good.
If the concept later proves to be a valuable or profitable one, then the lack of a thorough search for prior art becomes a serious liability because anyone who wants to use your concept can, if they can show prior art thru their own search, get your patent invalidated. Your expenses to get the patent and any defence of your patent that you have paid for is now wasted.
Some companies are now doing their own search for prior art before applying just to save the cost and aggravation of having a patent thrown out later.
Hope that helps.

The patent is 5,146,125
I think is absurd. The RASER company that we discussed earlier is the holder.

It could be a valuable claim if the Hall Effect were three orders of magnitude larger.
Like so many grand ideas, it awaits a quantum leap in materials science, or a miracle.

U R right - it is ridiculous. Part of it is possible and
part of it is new -- unfortunatelly the new parts
( Hall effect slab curved around the rotor, the full
current directly swithed by the Hall device etc ) are
impossible, and the possible features are not new.
