Arguably, there have been many great and compelling experiments produced by the field the past 33 years, but it is no further down the path to acceptance.
There have been good experiments, but they were not properly documented. They were not presented in way that could be understood by investors, reporters and other layman. (I am sure they could have been. That's the sort thing I do for a living.) Also -- and this is no one's fault -- no one made a video or on-line presentation of them, because that technology was not available yet. Okay, they could have made a video, but it would have been difficult, and not portable or uploadable.
F&P made a video of their boil off event, but they did not preserve it. The best copy we have now is the one I uploaded. The quality is terrible.
Years ago, I saw a close up video of a boiling cell. It was a perfect demonstration! As I said above, "it showed that the cathode was producing heat, the anode was not, and the bubbles were all from boiling, which was definitive proof of anomalous excess heat." It also showed a person's hand, indicating the scale of the device, and much else. I wish I could find a copy.
Maybe it is time to give skeptics what they have demanded all along...a device clearly demonstrating excess heat with some practical consumer use?
I do not think a device with some practical consumer use is possible. I do not think anyone knows how to make such a thing. We have to learn far more about the fundamental physics of the reaction before we can tackle that. Plus, no one in this field has the kind of knowledge you find at GE or Hitachi, and without that no practical product can be developed. If you try to make a practical product now, you will waste large sums of money and many years. In the end, you will accomplish nothing. You will not attract useful venture capital. Smart venture capital will see your device is far from practical. Stupid capital will waste more money on a premature development effort, instead of experiments to discover the nature of the reaction.
A proof-of-principle device might be worth the effort. That is how I would describe the Brillouin gadget shown in the video. However, it is poorly presented and the voice-over is technically inaccurate. It does not prove anything. Perhaps the presentation could be improved. I cannot suggest how to improve it, because the video does not reveal quantitative details, so I do not know the performance parameters. Such as input electricity and output heat. Without knowing these details, I cannot suggest how to improve it. Frankly, I have no idea what is going on in that demo, or whether anything interesting is going on.
The fact that there are no quantitative details is the biggest problem with the demonstration! Why on earth wouldn't you say: "X watts of electricity are input (shown here in this meter), and Y watts of heat are being produced (shown by thus-and-such method)"??? It seems like the first and most important information you should include in the video.
It was Garwin who said something like "boil me some tea".
Yeah. And when F&P boiled a cup of tea, he ignored it.
