The big test is today. See http://www.ecatnews.net
I was thinking of how to invest in this. Buy nickel? Maybe, but the amount of nickel used is very small? Buy hydrogen suppliers? Maybe. Hydrogen infrastructure? Local heating companies?
Short USO or oil? Sell all my PMs? ;-) No, since I think that PMs will still be needed as we will have inflation. In fact, if the E-cat works and we have a huge boom, with all the fiat around, this should be inflationary and PMs should do well?
Finally, I bought some Google calls, since the rumor is, that Rossi's "customer" may be Google. The evidence? Slim, except that if you put in e-cat.com into your browser, see where it goes. We should know by tomorrow.
Maybe someone else has some better advice?
