On Fri April 30 Jones Beene said [quote]Possibly, but if you are looking for Casimir cavities, there are probably far better choices from nature (or rather from altering nature) than mere limestone. A search for nanoporous calcium carbonate turns up many jewels: http://www.electrochemsci.org/papers/vol4/4111541.pdf. including the factoid that this material has a capacitance of ~650 F per g!

Jones, Thanks for a great citation and yes I should have specified calcium carbonate in the thread - according to Wikipedia [quote]Calcium carbonate is a chemical compound with the chemical formula CaCO3. It is a common substance found in rock in all parts of the world, and is the main component of shells of marine organisms, snails, pearls, and eggshells. Calcium carbonate is the active ingredient in agricultural lime, and is usually the principal cause of hard water. It is commonly used medicinally as a calcium supplement or as an antacid, [/quote]. It looks like limestone and antacids are a readily available source of calcium carbonate. I would like to experiment with it but after finally repairing my HHO /torch kit am coming to the conclusion that HHO is an issue and I really need a pure hydrogen environment for the lime or lime mixtures with other nano powders.
