Andrea Rossi Granted E-Cat Patent by US Patent Office

Thanks to Mcloki for sharing this very important news as far as the E-Cat is concerned (and all who emailed me).

Mats Lewan has posted on his Impossible Invention blog that Andrea Rossi has been granted a US Patent

The patent was granted today, August 25 2015. A link to the full text his here:

More to follow.

This should be a very significant event in terms of replication of the “Rossi Effect”. There have been a number of efforts already by people who have studied Rossi’s statements, E-Cat test reports, and the work of other replciators like Alexander Parkhomov. Now we have some important new details that should help replicators — and I am sure new replicators will get in the game now.

One interesting excerpt from the patent that should be helpful:

“Variations in the ratio of reactants and catalyst tend to govern reaction rate, and are not critical. However, it has been found that a suitable mixture would include a starting mixture of 50% nickel, 20% lithium, and 30% LAH [lithium aluminum hydride]. Within this mixture, nickel acts as a catalyst for the reaction, and is not itself a reagent. While nickel is particularly useful because of its relative abundance, its function can also be carried out by other elements in column 10 of the periodic table, such as platinum or palladium.”

I asked Rossi on the JONP how they were able to turn things around after the patent had previously received a final rejection by the USPTO. He replied:
