I wonder wether all present powder will be active at once. It seems only part of the the powder is in an active state. If all powder is in an active state all the time, COP will decrease over time as the material is 'consumed'. This would mean, in the case of an e-cat, COP is only 6 in the initial

Rossi must keep the COP at or below 6 to avoid reaction meltdown. The LENR reaction must be controlled to avoid the disruption consequences of infinite COP. On Mon, Jun 10, 2013 at 6:43 AM, Teslaalset robbiehobbiesh...@gmail.comwrote: I wonder wether all present powder will be active at

I am aware. But to keep COP of 6 this either means over time, due to the reduced amount of nickel ( it is slowly 'consumed') the temperature of the remaining nickel has to be increased, or, the available nickel is only a part of the nickel is active at the time. If the temperature of the reduced

By the way, one of the reasons that the helium cooled pebble bed reactor design never made it in the utility nuclear reactor marketplace was its poor power density and “economies of scale” characteristics compared to light water reactor designs. On Sun, Jun 9, 2013 at 12:18 PM, Axil Axil

Major problem is that it is hot powder than needs to transfer its heat. It simply has a bad contact with the heat exchanger.

The heat transfer contact is very good because it is made by quantum effects caused by the BEC. I believe that the powder is super-fluidic. That means that the hydrogen gas and the powder and maybe even the containment tube are the same temperature (exothermic). On Sun, Jun 9, 2013 at 3:16 PM,

Pumping hydrogen through hot granulated uranium metal?  No wonder there is a reaction.  And the negative feedback UH3 moderator theory sounds a bit vague. If this was developed in the 1950s as an enhanced trigger in the Upshot-Knothole tests - then LLNL may have stumbled upon LENR without

Early Los Alamos heat pipes contained water or sodium. In the mid-1980s, Los Alamos developed a lithium heat pipe that transferred heat energy at a power density of 23 kilowatts per square centimeter—to understand the intensity of that amount of heat energy, consider that the heat emitted from the

Why are light power dense LENR power plants necessary? A Boeing 747 engine produces 25 megawatts of power per combustion turbine. Twenty-five megawatts is the equivalent of about 33,500 horsepower. The Pratt Whitney jet engines used in Boeing 747s produce about 55,000 pounds of thrust on

Yes, apparently safe (although using UZrH not UH3). What I was questioning is whether the hydrogen desorbtion at high temperature really does control the reaction by changing the neutron moderation rate, or whether something else is happening (which equally controls reaction rate). It is not
