FIRST FREE ENERGY DEVICE REACHES MARKET IN OCTOBER -- The Game Changer is Here

Wow, the first search for "Gamma ray heat"

The process of ionization, which gamma rays are capable of inducing in all materials, is almost always accompanied by secondary processes of excitation in which electrons are excited within atoms, but the electrons are not removed from the atoms. In general, most of the energy transferred to electrons by ionization ends up as kinetic energy of the electron and is lost mostly and ultimately in the form of heat, as is much of the energy of excitation. Thus the direct conversion of gamma energy to electric current is very inefficient. However, it is possible to convert heat to electricity. In fact, when nuclear power plants operate, a small, but not insignificant, portion of the power generated comes from heat generated by the decay of the radioactive fission products that build up in the fuel. The decay radiations include primarily beta particles and gamma rays, both of which produce heat. This heat adds to the fission heat that is used to convert water to steam to drive the turbine/generators. Also, electricity can be generated from heat through the use of thermoelectric generators (e.g., a series of thermocouples, called a thermopile, in contact with a heat source), which have been around for decades and have been used with a variety of heat sources.

cheappower2012,

What makes you post something like this?

Did you honestly fail to get any search hits concerning heat produced by gamma rays?

Or who are you?

I did just as lumen and got the hits depicted below in my first search attempt.

But is the heating of the lead by gamma rays really the mechanism by which Rossi's reactor gets hot? At one point he made the statement that it was, you may recall.

But.... for something to be able to heat water/steam to 600 degrees C by conduction/convection, that something needs to be that hot at least. And if you stop feeding it water to heat, it will get _much_ hotter than that. Is this not right?

What is the melting point of lead? Where is the evidence for a quantity of lead, heated to 600 degrees C, in anything that Rossi has shown? How can a quantity of 600 degree lead--- or much hotter lead, through a secondary heat exchanger--- heat up water effectively?

How can 1.5 grams of nickel powder heat up something to over 600 degrees C and transfer that heat effectively to water/steam, using some 600 degree hot lead as the gamma absorber to turn the high-frequency gamma radiation into lower-frequency heat? At a rate of 10 kW?

Nowhere, no way, in none of Rossi's plumbing, has there ever been any evidence of molten lead shielding, reservoirs, or heat exchangers using molten lead.

TinselKoala:

Even though you are right on all accounts, you are making many assumptions,
Just because the reaction can be controlled to 600C does not mean you would be getting this in a home unit!
Even in a Fission reaction much of the core heating is caused by gamma rays absorbed in the core itself, only those emitted near the surface and emitted outward are able to leave the core. One should calculate surface area only for percentage of emission.
When he said the heat was caused by gamma ray absorption, I believe everyone thought into the lead shield and not the core which does most of the absorption.

[TinselKoala]

So then the home units, which we have seen almost entirely stripped down, are working on a different principle? All the lead in those units is on the outside, comprising the shielding.

And the large, "ottoman" unit that was disassembled all the way down to the heat exchanger.... there was no reservoir of molten lead in there, just the external shielding. Different principle?

And the "1 MW" plant... which actually didn't even reach half that figure, and was composed of a bunch of the ottoman units.... a different principle than the current production line?

Rossi said that the heat is produced when gammas are absorbed in the lead. Is there other lead somewhere in his current design?

I am making assumptions, sure. You can help clear up some of these assumptions. Could you describe to me, just a sketch will do, of some kind of design that has a gram and a half of powder, emitting whatever, heating up some kind of heat exchange system that will then produce 600 degree C steam, at a rate of 10 or 20 kW? I don't care how the power is generated.... I just want to see somebody tell me how to get that much power OUT of that small mass, however it's distributed by volume, and put it INTO a flow of 600 degree steam at a rate of 10 kW. Be sure to include the use of lead as the heat source for the steam heating, however the lead itself is caused to heat up.
