Clean HME, Vegatec and Hydrotalcites -Discussion Thread.

The work on Hydrotalcites - which are basically synthetic minerals - is of increasing interest to LENR researchers. This paper has been posted before, but perhaps it is time to look again at the Vegatec / CHME work.

Abstract
We have developed new kinds of materials made of nanoparticles of nickel-based alloys that show production of anomalous heat in an atmosphere of hydrogen. These materials are produced starting from hydrotalcite acting as precursors of nickel and nickel alloys supported on an amorphous alumina phase. The experiments are performed in a custom-made heat-flow calorimeter having a precision of +/−100 mW from room temperature up to 950◦C. This report shows that excess heat is produced when hydrogen is introduced into the reaction cell, however more excess heat is measured when the hydrogen is pumped out.

DESCRIPTION OF HYDROTALCITE SYNTHESIS - Christophe Le Roux, CNRS, France CleanHME Consortium

An atom like hydrogen is composed of a nucleus (composed of only 1 proton bearing 1 positive

charge) surrounded by an electronic cloud (composed of only 1 electron bearing 1 negative

charge), the right balance of negative and positive charges being responsible of the electric

neutrality of the atom. In the world of minerals (crystallized structures) composed of 5744

identified and referenced mineral species1

, one can find hydrotalcite (abbreviated as Htc)

which is a member of the large Layered Double Hydroxide (LDH) familly. Htc, is quite common

in nature since it is composed of common chemical elements found in the earth crust such as

magnesium, aluminum, oxygen, hydrogen and carbon. In nature, one can find it’s nickel

analogue called takovite. Such chemical elements initially in solution in water (rivers,

groundwater) usually precipitate where they meet (like confluence for rivers). Carbon (the

major building block of life) is the only element on earth that can exist in tree forms: solid

(graphite), gas (CO2) and liquid (when CO2 dissolves with water and solubilizes into carbonic

acid (H2CO3) and thus can be incorporated into minerals in the form of carbonates2

).

Hydrotalcite belongs to the carbonate family since it is an association of a carbonate (A = CO3

with n = 2, see figure below) and Metal hydroxides layers (with M = Mg and Al). To make it

simple, the balance between di-cations (MII such as Mg2+ bearing 2 positive charges) and trications (MIII such as Al3+ bearing 3 positive charges) creates an excess of positive charges in

the layers which is balanced by anions An- (such as carbonate bearing 2 negative charges)

located between the layers, the right mixture of both charges being responsible of the electric

neutrality of the crystal structure.
