New USPTO Patent Applications

If there is uranium-238 present, the rate of spontaneous fission will be much higher.

In what context is this true?

I am just wondering why the U238 is removed to make enriched U235 for the fuel.

Quote from Dr Richard

So if we apply the same principles to fusion

Free neutrons are detected at very very low amounts... far below U235 emissions.

The LENR appears to be sustained in hotspots or " otspots"(Biberian) for long periods

in palladium/H2 electrolysis.. 50 -100 ? microns in size

the mechanism of limited propagation appears to have something to do with the

isotopic/isomeric makeup of the hotspot..perhaps metastable isomers.

if they were releasing low energy neutrons they are more likely to be absorbed into fusion with protons and deuterons to form more deuterons and tritium - so may not be released from the electrodes accounting for a low detection rates, perhaps.

On a very simplistic level, I was applying the same laws that govern fission to fusion. We would not expect any heat production from sub-critical gram quantities of uranium powder so we should not expect it from such small gram quantities of NiH or PdD powder experiments. Electrolytic nuclear experiments as in F&P or where radio frequency pulses or lasers are applied may increase the effective density therefore lowering the critical mass required. Just interested in seeing replication of the thermacore runaway, spontaneous accidents have often led to breakthroughs in the past. i

sub-critical gram quantities.

Like these? They look to be about 0.5-1 gm.. but I don't know the density.

Perhaps Alan knows the mass

The Thermacore runaway used 200 mesh Ni particles - perhaps using a similar quantity of granules might achieve a similar effect packed into some sealed vessel. Easier just to use fine Ni powder to replicate the experiment - if it works we gain a lot in terms of the ability to scale up LENR, if nothing happens and this turn out to just be LENR mythology, we lose nothing. Nothing ventured nothing gained though.

Quote from Dr Richard

from all accounts the Russ George reactors use a single granule a few rice grains in size.

the LENR anomalous heat rate from this was of the order of 25W from memory

so perhaps the laws governing U235 critical mass fission do not apply.

Still like to see if that scales up linearly or not. Sure don't expect exactly the same rules since in fission one neutron collision produces up to three new neutrons so the chain reaction is extremely high rate. In fusion only two neutrons result from the reactions DD and DT to T and He.

That's very impressive - so the rotatoral collapse flux theory predominates? Can it be enhanced or suppressed by powerful magnetic fields? Is that how you can distinguish between thermalsation by radiation or by the flux mechanism - still be interesting to scale it all up 1000-fold which would account for the Thermacore runaway reaction being able to melt steel. There could be a larger contribution from radiation thermalisation in a larger reactor sample, perhaps.

Quote from Alan Smith

Only if you assume all heat comes from the thermalisation of radiation is critical mass a big player. We estimate that only about 1 part in 10^-9 parts of the heat we are seeing is attributable to expressed radiation, the bulk of the heat comes from the model desctibed by Wyttenbach's flux theory. We are running 2 grams approx currently and have seen enough heat to melt quartz and alumina - a delta -T of 600C+ over the maximum possible reactor temperature.

Alan, I am not suggesting that the following is actually happening, but wondering if you have ever seen it. Apparently high silica glass is affected by magnetic fields and the melting point can be lowered by several hundred degrees within a strong field, in some cases. There has been some studies funded by Corning in this regard. Also it was found that the glass is affected through essentially the same mechanism when the glass is used as a resistor, and at and around the positive connection the glass changes state somehow and gets very much hotter, and melts while the rest stays much cooler. Probably your experiments do not make a strong enough magnetic field to change the glass state (not sure what strength is needed, but certainly much more than a fridge magnet), nor do you use glass like a Joule heater. Anyways, a neat and unexpected effect, and not much studied in other non-metallic materials as yet.

Quote from Max Nozin

Drgenek correct me if I am wrong but if you know how to get low energy photons combine into high energy ones would ia new type of x-ray/laser and a Nobel perhaps?

is seems like the second law of thermo would forbid such things. How is entropy treated in such a case?

Quote from Max Nozin

That is what I am wondering too. Also search for 'phat laser'.

If you read Pharis Williams book, he mentions that his proposal to build a phat laser was read and taken serious by the US government. He claims that Ronald Reagans suggestion to build laser defense system against missiles was a result of his proposal.
