MFMP followers propose a new calorimeter

Geschrieben von Robert Greenyer am .

We are regularly reminded of the high calibre intellect and skill of the people following our efforts to challenge the claims of others researching this field. We are certain that there are much more capable people following this project than are directly participating. It is great then, that on a regular basis, some of these people step forward and show what they are able to do.

We just received a submission from two followers, Bob Findlay and Bahram Farahbakhsh of a proposed calorimeter, these guys modelled the thing in COMSOL Multiphysics and made a study of the design as set out in the paper they provided below.

The MFMP team members, are pretty tied up with experiment builds at the moment. So, we have a question, as this was a crowd designed and modelled calorimeter, would the crowd like to work on a mini-project to see it realised?

We could set up a Basecamp for a dedicated team to coordinate with and a thread on the site in the collaborate section to share details with the crowd. When the calorimeter is realised, we may then be able to step in and run it/help instrument it and get it on the live feed.

Has anyone out there got the skills and resources to try and work with these guys and build the conduction calorimeter? If so, get in touch by using the green "+" on the right hand side.

For now, check out their excellent work below.

@Ecco I agree that the conduction calorimeter would be a perfect fit for the Celani style experiments. It is by no means restricted to those experiments. By simple changes in tube size the conduction calorimeter could accomodate any form of LENR material and geometry.

A better (proper) calorimeter like the one proposed would be useful in checking out whether Celani's latest idea is actually increasing excess heat or just affecting the cell's heat transfer mechanism:

One thought, although we didn't simulate it, would be to use a thin air gap as the sensor layer. ie. two concentric Al tubes with thermocouples close to OD of inner tube and ID of outer tube. If the air gap was narrow enough heat could only be moved by conduction. To help immobilize the air in the gap we could use fibreglass insulation.

Construction of such a device should be straight forward. Temperature sensing should be perforemd with a thermopile stack molded into a ceramic material cast on the outside of the metal tube. The cast layer could be 1 cm thick (or whatever) The thermopile would sense the temperature differnce between near to the metal tube and near to the outside of the ceramic layer. The ceramic can be cast in multiple layers and built up to the required thickness. A good material is Cotronics #780. This is a dry powder mixed with water much like portland cement. Adjusting the viscosity allows either casting or trowelling like plaster. Thin layers are easily constructed. The resulting material is usable to 3000F. (2200C)
The thermopile should be bulit to fit within the ceramic layer. It will be permanently encased in the ceramic slurry. A few dozen short pieces of bare thermocouple can be welded together in a fence like structure and carefully added to the ceramic assembly.
Temporary structures (adhesive tape, plastic pipes etc.) can be used for creating the dams needed for the casting. Some of the layers can simply be troweled in place (like plaster). It will take a week or two for the curing of the many layers of ceramic material. The final structure will be rigid and heat proof. It will completely surrond the metal tube and needs little or no machining for the assemply fixturing.
It looks like a straight forward project with minimal cost and risk.

Thanks for posting our paper here.

We'd be pleased to participate in a crowd design exercise.

The simulation demonstrated that the physics behind a conduction calorimeter is sound. What the crowd could do is design a simple, economical and easy to manufacture/ass emble version.

This type of calorimeter would not be restricted to Celani wire style experiments. It could work equally well for planned powder work.
