Several presentations have now been uploaded to the upcoming LENR Workshop in Memory of Dr. M. Srinivasan. You don't have to wait for the Workshop. Some of the slide presentations have a voice-over so you get the whole presentation. Mine does, and so does Frank Gordon's, which is interesting. You can download the presentations and hear them now.
Maybe they all have voice-overs? I have not downloaded them all. Tom Grimshaw did a video presentation. See: https://docs.google.com/document/d/1n9Fce0UMU4ch23mvCJ9XYAy8Ac43V5Tt9EwDlm6hocU/edit# Incidentally, adding an audio track to a PowerPoint slide is harder than you might think. I suggest you practice for an hour or so. Try playing back several times. There are some tricky aspects of it. For example you have to pause between slides or the audio track fades out and then booms back at the next slide. The pretend laser pointer feature is hard to use. You have to have three hands. It is even harder with the computer mouse I use, because it has no buttons. (Don't ask . . .) You have to hold the laser for a while and move it slowly, which I did not do, as you see from my presentation.
