Thanks to tlp for finding the following!

A new patent application has been published by the US Patent and Trademark office for “DEVICES AND METHODS FOR HEAT GENERATION” with Andrea Rossi listed as the inventor and Industrial Heat LLC listed as the applicant. The assignee is Leonardo Corporation.

The patent was filed on April 26, 2014, and was made public just today.

Here’s an abstract of the patent:

A reactor device includes a sealed vessel defining an interior, a fuel material within the interior of the vessel, and a heating element proximal the vessel. The fuel material may be a solid including nickel and hydrogen. The sealed vessel may be sealed against gas ingress or egress and may contain no more than a trace amount of gaseous hydrogen. The sealed vessel is heated with an input amount of energy without ingress or egress of material into or out of the sealed vessel. An output amount of thermal energy exceeding the input amount of energy is received from the sealed vessel. The fuel material has a specific energy greater than that of any chemical reaction based energy source.

This deserves careful study, I think.
