The paper you cite refers to metal hydride. That is where I would expect the source of heat is from. Basically an expensive battery.

Hydrides are a favorite tool of scam artists. They have high energy density, look like rocks, and release energy when exposed to water. They get passed off as an energy source, but are no such thing. Rather they are an energy storage medium, and so long as the ‘charging’ process is done off stage, short demonstrations can be very convincing and misleading.

There are numerous fellows out there using metal hydrides because, in fact, you can build up a charge on them.

Now, some references to the scam artists and their tricks ~ bring them on. Always interested in what they're up to.

Note, the "hydride" in question refers to a very small amount usually used to assist in "tuning" a free neutron to the right power level ~ which requires reading a number of other papers to understand properly (so you are stuck with my non-scientist reportage on that item).

If they can drop HUGE amounts of energy into these small needle shaped devices they've certainly got some winning batteries.

I don't recall encountering any reports that had large sheets of hydrides involved.
