In this document from 2007, Letts wrote that he
could not make laser stimulation work. It stopped
working for years. As I noted here, after he
wrote this he discovered the problem (we hope)
and he now makes laser stimulation work reliably,
and repeatedly with the same sample. See:

I have not heard whether he has done this
experiment at EarthTech again. He and D2 were
doing it in their own lab last I heard.
They reported: ". . . increasing cell operating
temperature from 62°C to 73°C increased excess
power production from 225 mW to 900 mW, a 400%
increase." This level of power requires a
reasonably good calorimeter, but not a super good
one. I am confident that the calorimeter is built
by D1 and D2 can measure this much power with assurance.
I prefer the Seebeck design over the MOAC style flow calorimeter.
