Open Source Cold Fusion Replication Plans Now Available

This doesn't look like a lenr to me. This is electrolysis+ hv combustion of the h2.

I must be missing something. He pumps 80 to 100v DC at 20 to 30ma  into a 10% solution of sodium hydroxide using a tungsten electrode that combusts the HHO and Sodium and the weight of the electrolyte solution increases as the Tungsten rod breaks down and this is obvious by the discoloration of the solution.

People have been doing this for years but graphite works much better than tungsten.

The rest is just mathemagics with numbers as NAoH and H2O is an exothermic reaction that he initially uses heat as a catalist (heating to 60 degrees C).

This is one of the rare videos where someone has actually done a energy in/out calculation for a "cold fusion" in a jar type experiment. This is the only one for me where this is done, so congrats!
BUT, there are problems


This is not the proper way to measure input power. The cheap multimeter is struggling to measure it and most probably giving a wrong reading. The waveform for a sparking electrode will be very messy with a very high frequency content. The current needs to be rectified or it must be measured BEFORE the transformer.


He did install an energy meter (kWH meter) but never shows the closing reading on it. I'd trust it more. BUT again, its designed to measure in kWH range not in a few watts and will be highly inaccurate.
And yes, as others have said, there can be other sources of heat, like exothermic reactions.
