An Analog Approach to E-Cat Control (Axil Axil)

I have remarked repeatedly that the Rossi digital approach to reactor control was overly complicated, error prone, inherently unreliable, a high maintenance nightmare, and unnecessarily costly. I would like to put forword an alteritive method of control that is analog and simple in the extreme and is everything that the Rossi approach is not.

This alternitive approarch involves the use of high temperature shape memory material.

In detail, a simple way that shape memory materials might be used in a LENR reactor is to form Micro particles out of high temperature shape memory material such as Ti–50(Pt,Ir) or Nitinol (50Ni 50Ti).

At reactor temperatures lower than the operating temperature setpoint, the shape memory micro particle would be shape set to be covered with LENR activating nanostructure like tubercles. But when the temperature increased beyond that setpoint temperature, the topology of the micro-particle would change so that the tubercles would recede and then disappear.

As the LENR reaction lost strength as a reaction to the removal via shape memory adjustment of the tubercle structures from the surface of the micro-particles, the operating temperature of the reactor would naturally drop below the operational temperature set-point, the tubercles would reappear once again as the shape memory surface of the micro-particles would recover its original shape.

In response to the lower temperature and the resultant reappearance of the tubercle surface, the Ni/H LENR reactor would once again increase in temperature due to reappearance of the tubercles on the surface of the micro-particles.

In this simple an uncomplicated way under analog control, the Ni/H reactor would automatically maintain in a failsafe and totally reliable manor a constant thermostatically controlled optemized operating temperature.

    I personally dont see anything wrong with the way Rossi is trying to control his reaction.
    Especially since this reactor is the first of its kind I think its important to focus on a control process already established.
    Are you sure this “high temperature shape memory material” can reach the reaction speeds necessary to keep the reaction in a stable temperature range?

      Another question is if the temperature is the cause or a symptom of a runaway reaction…

        I think its a symptom of a runaway reaction.

        Edmund Storms has some exciting ideas. Here is a link to a phone interview with him.

          thanks!

    Axil: After 3 years following and participating in E-Cat discussions, this is the first time I’ve heard someone clearly outline a logical method to control runaway heat problems surrounding the E-Cat. If yours is a valid solution, you solved a major over riding problem. Very commendable. Thank you.

    One key problem you will have is that your proposed use requires the alloy to be constantly flexing and stiffening this will result in work hardening leading to fatigue and fracturing and loss of key properties, which might negate your proposed use. There are additional alloy materials you can add as well as various heat treatments to reduce this but I suspect it could be a big problem.

      I agree. Besides that, I assume that Hydrogen brittleness will cause increased cracking of the alloy, making it unusable. But maybe we are wrong. One can always try.

There are additional alloy materials you can add as well as various heat treatments to reduce this, you might get lucky and the Ni to Ti ratio you want to reach your work temperature may be fine, but also beware of hydrogen alloying and potential embrittlement issues!

  • Obvious

    This incredibly more complicated to engineer than turning heat off and on, IMO. I do give it points for novelty.

    Edit: hydrocarbons exhibit this type of “memory” unfolding with temperature, so simply adding carbon of the right dimensions could possibly perform this function. Phase change of other simple molecules could also work like this.

    This could make for very simple reactors, perhaps for computer / phone batteries. However, seems like it would require a substantial R&D effort with substantial risk of failure. Someone will likely give it a try.

    Try looking up PTC (positive thermal coefficient) ceramic heaters. They are self regulating at any temperature you choose.

    I believe that this reactor can’t be controlled for longer period with Analog technique. I think that to maintain such process and to get the best performance you have to control the process logically.

    As I have observed in Parkhomov notes, reaction can occur even without applying input power for short period. And this is the time that can be used for the best efficiency (the highest COP values).

    With proper regulation algorithm input power can be precisely controlled with fast PWM pulses. Depending on the feedback it must be well tuned to stay in temperature levels that can’t harm reactor.
    Important can be also to get precise and fast temperature sensors so the response can be fast and accurate.
