Re: [Vo]:A catalytic converter might be a cold fusion cell
Hmmm... Actually, a few years ago there was indeed a flash of interest in doing this - using catalytic converters for thermal gain.. Many videos turned up on YouTube. Search for "H-cat" Nothing was memorable from this extensive effort IIRC, but these efforts were generally using H2 instead of D2.

[Vo]:A catalytic converter might be a cold fusion cell
I have often noted that Pd thin film catalytic converters resemble cold fusion cells. Actually, for all anyone knows, they might *be* cold fusion cells. I have often suggested the someone should buy a brand new one, fill it with high pressure pure deuterium gas, and then heat it up. It might produce anomalous heat.

Re: [Vo]:Thorium breeding now?
In reply to bobcook39...@hotmail.com's message of Wed, 1 May 2019 02:47:34 +: Hi Bob, Some points. 1) The fuel is dissolved in the water, so initially there is no fuel in the reactor until water is added, then criticality is achieved at startup by pulling control rods somewhat once the water (and fuel) has been added. At this point, the negative temperature coefficient is already in effect. 2) If all the water were to rapidly evaporate, and leave a solid salt (impossible by the way), the reactor would long have shut down because only fast neutrons with a too small fission cross section would remain (i.e. no moderator). If the water were all to leak out, then the fuel would go with it leaving an empty reactor. Leakage should probably be caught in a flat tray with an area large enough to ensure that only a thin layer could exist even with all the water from the reactor in it. The large area thin layer would ensure that too many neutrons would be lost to sustain a chain reaction in the pan. This is a passive safety measure. Furthermore anything leaking into the pan under normal use could be pumped back into the reactor ensuring that it could keep running normally even with a leak. 3) Because fission products are constantly being removed during operation (liquid fuel cycle), there would be few left to produce decay heat, so a melt-down could not happen. 4) If all external systems fail at once, and there is no leak, then the water boils off (pressure release valve) and the reactor shuts down (no moderator). 5) Another advantage of a liquid fuel reactor is that the total fuel load in the reactor at any one time can be kept small, and fuel constantly added as required. I.e. it doesn't need to have years worth of fuel in the reactor at all times. This is another safety feature. >Without waterlost in the steam productionthe negative temperature coeff.

Re: [Vo]:Longitudinal, scalar, spin and Seebeck waves.
It could be helpful to those working on longitudinal wave Seebeck or other similar devices to compile a listing of actual devices which convert ambient heat to electricity. What is the highest electrical output reported so far? This listing would not include the MEMS devices which convert mechanical vibration, although at some point mechanical and thermal do merge. Here is a start - from 2012 - the output is visible light from an LED Self-Charged Graphene Battery Harvests Electricity from Thermal Energy of the Environment | | | | Self-Charged Graphene Battery Harvests Electricity from Thermal Energy o... The energy of ionic thermal motion presents universally, which is as high as 4 kJ\bullet kg-1\bullet K-1 in aque... | | | There is known phenomenon in physics called the "longitudinal spin Seebeck effect". The leading paper seems to be from Uchida : Observation of longitudinal spin-Seebeck effect in magnetic insulators Appl. Phys. Lett. 97, 172505 (2010); https://doi.org/10.1063/1.3507386 The carrier of spin for this effect is the magnon. There is pronounced heat transfer but no violation of the Laws of Thermodynamics. This is not exactly the same thing as the so-called scalar wave, which is high on the bogosity index. Seehttps://rationalwiki.org/wiki/Scalar_wave The lore in alternative energy going back to Tesla involves the scalar wave. Sometimes this wave can manifest as having a temperature gradient and has been called "cold electricity" but it is a mistake to conflate the two main concepts: the scalar wave and the longitudinal spin Seebeck effect - although there does seem to be plenty of overlap. Then -- we start to bridge the gap between standard physics and crank free energy inventors with ANE. The "anomalous Nernst effect" (ANE) is a thermo-magnetic effect that describes the the interplay between heat, spin, and charge in magnets and coils. Compared to the standard Seebeck effect, the ANE reputedly has higher-efficiency, leading to energy-harvesting devices which can convert ambient heat directly into electrical current in a longitudinal vector. In fact, ANE and LSSE are probably different aspects of the same phenomenon. This post is intended simply to put these terms out there for future reference, since there are already devices out there which convert tiny amounts of ambient heat into tiny amounts of electrical current. The big challenge - as always with any device rooted in QM, is quite simple. Does it SCALE-UP ?
