Title: Cold Fusion Defkalion Live Demonstration Review
Post by: markdansie on July 24, 2013, 03:57:56 PM
This was at least had the right intent. It fall a little sjort of being fully independent and would not be called conclusive but was a good experiment to watch
They appear to be well in advance of anything Rossi has and a lot more open

When the layers are peeled away, though, the story turns out to be much the same as Rossi when he was still using water and steam, as in the big "1 MW plant" and the individual 'ottoman' ECats. The problem "boils" down to the quality and quantity of the output steam.

Consider: they claimed to be pumping about 500 mL of water per minute into the unit, and they claimed to measure around 4.5 kW output power, at least during the segment I watched. Some simple math shows that those numbers do not correspond to what was observed at the outlet pipe in terms of steam quantity, velocity, and condensed liquid water flow. Where did all that steam go? For at least a little while there was NO liquid water coming out the outlet pipe dangling into a sink ... so presumably all 500 mL per minute of the input water was being turned to steam at 160 degrees. Steam has 1600 times the volume of the water that made it. Half a liter per minute water IN means 800 Liters per minute of steam OUT. Can you say "sauna"? But there was no sign of increased humidity or warming of their laboratory.

Consider: An expensive oscilloscope was connected to the circuit incorrectly... in fact very amateurishly... with the result that a Mains Breaker or Fuse blew and shut the whole building down for a few minutes. And probably also blew the scope itself, since it never was seen again after that. This event does not speak well of the general measurement and instrumentation abilities of the crew.

Consider: Instead of using a proper power analyzer instrument like a Clarke-Hess 2330 or a more modern Agilent or Amritsu instrument, they use a 100-dollar consumer-grade power monitor with a slow sample rate.

Consider: none of them are wearing safety equipment appropriate to working around a 160 degree C steam plant. None of them are concerned about gamma emissions from this fusion reactor. They claim that a 1-Tesla magnetic field could be "shielded" by a doublewall Faraday cage sitting on their workbench, and that they are delivering sparks of 110mA  x 10 kV  = 1.1kW power at a few Hz .... silently.

But they do NOT claim that they can disconnect the input power and still have the thing continue to produce its own heat... like they were claiming in 2011.

So the story is very much like the story with the last Rossi demonstration using water and steam. A demonstration that was hardly independent, that seemed deliberately designed NOT to demonstrate a test of hypotheses concerning a self-sustaining LENR power system, but rather to illustrate a set of ambiguous numbers that could be presented in support of some hand-waving claims.
