I've recently reconnected with @David.Daggett of Phonon Energy.
He made a presentation at the SAE AeroTech 2015 Congress & Exhibition
Here are : SAE_LENR.pdf
Phonon Energy has developed a LENR technology of their own, with promising results. You can see the test rig in the last slide in the presentation.
Because SAE AeroTech is aviation focused, the presentation is oriented towards an aerospace application. However, Phonon Energy is working to improve their LENR technology that can be used to satisfy practically any heat need.
