I uploaded a new version of this paper: Gordon, F. and H.J. Whitehouse, *Lattice Energy Converter (LEC) (PowerPoint slides)*, in LENR Workshop in memory of Dr. M. Srinivasan. 2021: Indian Institute of Technology Kanpur.
https://www.lenr-canr.org/acrobat/GordonFlatticeene.pdf I added the Presentation Notes from the PowerPoint slides. The Acrobat conversion was supposed to include these notes, but it didn't work. I had to transfer them manually. The video of this presentation is here: https://www.youtube.com/watch?v=J4dzTWY_aWM&feature=youtu.be The version of the presentation given during the conference is in the Session 3 video starting at minute 37: https://www.youtube.com/watch?v=bd6JCbnYuaU&feature=youtu.be
