I've spent some time catching up on the hydrovoltaic air-gen research and I am surprised I knew nothing about it previously. This field of research has been going on for quite some time and the recent breathless news release by the group at UMass Amherst was likely an attempt to raise fresh funding.
If you're curious about it detail, read this: https://onlinelibrary.wiley.com/action/downloadSupplement?doi=10.1002%2Fadma.202300748&file=adma202300748-sup-0001-SuppMat.pdf Then compare the analysis of results to this: https://www.lenr-canr.org/acrobat/DiStefanoAexperiment.pdf I can't help but suspect that they are the same thing. Since the LEC seems to work with the the phenomenon of nanoporosity and doesn't necessarily need catalyst metals such as palladium, perhaps all of CF, LENR, CANR work on this principle and are not fusion at all, but some other phenomenon not yet well understood. Maybe it works like the atomic hydrogen torch, where splitting diatomic hydrogen and then recombining it results in large energy release. Or maybe the nanoporosity literally splits the diatomic hydrogen and then crushes it into the hydrino. Water molecules could be similarly broken down within the nanopores. The nanoporous aluminum film I made 10 years ago would likely work well for either the LEC or the air-gen. It was coated onto a PET film substrate and was a mirror on the substrate side and dead black on the exposed surface. The fact that a small drop of water literally vanishes into the surface of a film only about 400 nm thick and becomes hot at the area of contact would seem to indicate appropriate use in the LEC or the air-gen. Sheer speculation on my part. What's your take?
