I watched the blacklight promo video performed at Rowan University. Notice the reaction starts at around 100C peaks very quickly then dies off quickly. This seems to start at too low a temperature. I'm not a chemist or nuclear engineer, but to me this seems to be a simple Lithium chemical reaction as it had no sustaining power, despite their claim of a megajoule or approx 40 Watts for 7+ hours.

Any comments?

I managed to find something on the web:  'NaH experiment
I plan to try a scaled up version of the experiment that Blacklight
Power did using Sodium Hydride in a Differential Scanning calorimeter
(DSC).  BLP did not use Raney Nickel in this experiment.  BLP put a
0.067 gram sample of Sodium Hydride in a Differential Scanning
Calorimeter and measured a heat output that corresponded to 354
kJ/mole H2 in the temperature range of 640 C to 825 C.
Below is a link to the NaH experiment done by BLP - look at page 21
and page 49 showing the graph of the output from the DSC:

A Differential Scanning Calorimeter compares the energy needed to
heat a reference sample, such as alumina powder, with the sample
being tested (such as sodium hydride).   The two samples are in
separate ceramic fingers and heated with separate electric heaters
and monitored with separate thermocouples.  The samples are heated to
a high temperature at a controlled rate (0.1 Deg C per minute in this
experiment).  The electric heaters for each sample is controlled so
that if there is an exothermic reaction, the heat input to the heater
is decreased so that the heating rate is constant.  The  amount of
heat energy from the exothermic reaction is measured based on this
reduced energy input to the electric heater.
My scaled up experiment won't use a Differential Scanning Calorimeter
or measure the energy output but will just try to show that there is
a temperature increase when sodium hydride is heated to high
temperatures.
I plan to put somewhere between 5 and 50 grams of  Sodium Hydride etc etc'

0.06gram NaH is a tiny amount,surely chemical reaction can be ruled out fairly easy? One could open the bomb after the run and test volume of h2 released after reacting 2NaH + 2h2o= 2Naoh + 2H2.chek volume moles of H2 left after run and compare? There should be some undecomposed NaH from equilibria NaH>< Na + H (if there's no water vapour in there or hydrated compounds)

One could substitute LiAlH for NaH? Mix in some powder alumina to go?

 From profitis:

The electric heaters for each sample is controlled so
that if there is an exothermic reaction, the heat input to the heater
is decreased so that the heating rate is constant.  The  amount of
heat energy from the exothermic reaction is measured based on this
reduced energy input to the electric heater.

Yes, I have an alternate program setup that uses exactly that method.

Ultimately I may use some form of induction heating as it can be much more efficient at heating the Ni mixture directly, but the particle size may be too small to be effective.
