Visit to Coolescence
Last week, the HUG team went to visit Coolescence in Boulder Colorado. Rick Cantwell, has lead their small team through many replication attempts in the field of Cold Fusion over their 8 year history. To date they have not been successful in seeing either nuclear evidence or excess heat that can't be explained in a more conventional way. Listening to their stories and insights from 8 years worth of work in this field was fascinating. We are just getting to the point where we know enough to appreciate the experience Coolescence had to offer. They also pointed us towards Earth Tech International (earthtech.org), another team that has done quite a few Cold Fusion experiments.
Near the end of our meeting, we talked about Live Open Science with professor Garret Moddel from Colorado University. Professor Moddel has also done quite a bit of interesting research in related areas, and some even more interesting research in some unrelated areas.
The picture below is a panoramic view of us all sitting around a conference table and talking about cool stuff.
From his deep experience in the field Rick offered some useful criticisms of our report from a couple weeks ago about some apparent success on the V1.3 cells running in differential mode.:
I have some comments and questions on your latest experiment.
- In Image 1, why are you using come Cu tubing rather than all stainless steel?
- A schematic of the gas system would be helpful - I didn't appreciate the significance of the comment "both valves open"
- If we've only learned one thing it is that T != E. Temperature is not a reliable proxy for energy.
- I'd like to see power normalized delta T plotted - my guess is during phase 1 it is about the same (but opposite sign) as during the proposed excess period. All periods of unequal temps have to be explained, not just the one where B >A.
- Related to #4 - what is the explanation for the endothermic phase?
- Is there any correlation with room temp and delta T's
- Is the A vs B pattern consistent across all three temp probes on the cell?
We will be endeavoring to answer these and see if we were really just fooling ourselves. If we are fooling ourselves, a change in air flow is the most likely culprit. The emissivity of the wires was most likely unchanged between periods of higher measured temperature, so making opaque wrappings for the glass doesn't seem like a great diagnostic next step. Instead, we are pursuing stabilizing the thermal environment around the cell, first. We had previously put the cells in a box made from twin wall polycarbonate and fed the box with constant temperature air. This time we are using extruded polystyrene foam board, some aluminum, and a couple fans to make a higher performance isothermal box. Nothing wrong with making an opaque tube wrap at that time, too, I guess.
Survey of Possible Replication Efforts
Beyond the immediate problems with the Celani Cell calorimetry, and given the input from Coolescence, we would really like to explore the range of experiments that look the most promising. I would really like to hear what experiments everyone thinks would be the best to pursue. We have a skilled team, an equipped lab, and a network of advisors. We are willing and able to undertake the right initiative. What should we be doing?
Criteria for a replication effort:
Is it likely to be replicable?
- Has anyone else replicated it?
- Has anyone else tried and failed?
- Was the original work likely to be subject to known or probable errors?
- Is the originator willing and motivated to help us?
How much effort will it be?
- What apparatus and skills are necessary?
- How much time and money will it take?
Will it move the LENR field ahead?
- How robust will the results be?
- How understandable will the experiment be?
- How applicable to widespread replication will it be?
I am really hoping that the crowd of LENR enthusiasts will help us brainstorm and then research as we go through this very deliberate and thorough process. After we get enough ideas for a good list and settle on the proper criteria, I will openly share the document for group editing.
