A Very Simple and Inexpensive Glowstick LENR Test (Axil Axil)

The following post was submitted by Axil Axil

How to setup a very simple and inexpensive glow stick LENR test with a commercial microwave oven.

Use a microwave with a rotating glass turntable. Cover the glass turntable with a one inch layer of high temperature insulation.

Use a reactor design composed of an alumina or zirconia tube or a mixture of alumina and zirconia.

Put a fueled reactor and a unfueled reactor on opposite sides of the glass turn table. Use a IR temperature meter to measure temperature. Turn the microwave oven on and off automatically based on a program of gradually increasing minimum and maximum temperature setting of the reactors as they rotate on the turntable.

The unfueled and fueled reactor will receive the same average input power over time. If the LENR reaction becomes active, the fueled reactor will be hotter than the unfueled reactor.

    This controller was the basis for the test controller concept as discribed below. The unit was built by Skip and has most of the features required by the test controller but it is dumb. What needs to be added is a microprocessor that adds some intellegence to this unit.

    This idea is far from simple. First of all, why a microwave oven? The heating in a microwave oven varies with the material being heated. Alumina does absorb microwaves. How much is unclear. Whether the contents of the alumina tubes will make a difference is unclear. The effect of microwave energy on thermocouples and thermocouple wires, however, may be of greater concern. Absent extensive exploration, these details cold loom large in an uncontrolled way.

    Far simpler: a tube furnace large enough to contain several fuel tubes. The tube furnace is electrically heated, thermostatically controlled to follow a controllable temperature ;profile. The heating coils would be Kanthal and would not be insulated from the interior of the tube furnace. I would wind them around supports, the support assembly would insert into an alumina tube that forms an inner wall of the furnace; the exterior of this would be insulated.

    Imagine fuel tubes, sealed by design, found to usually maintain integrity when heated to release internal hydrogen. In a series of experiments, leakage should be tested. Tubes which leak would be identified by a small loss in weight (if they don’t fracture or explode). Leaky tubes would still be useful as a kind of control, they will contain everything but would have lost most of the hydrogen. Developing fuel tube design so that performance is relatively uniform is an important first step. Thicker alumina could be used than in the Parkhomov design.

    Uncontrolled tube failure is exciting, but may be meaningless.

    A fuel tube is held centrally in an alumina cylinder substantially larger than the fuel tube. There is a thermocouple mounted on the inside of this cylinder, and another is mounted on the outside. The physical relationship of the fuel tube with the inner thermocouple would be fixed.

    If there is no energy generation in the fuel tube, the thermocouples will both be heated by the tube furnace. While the inner thermocouple will lag behind the external, they will approach the same temperature. If there is energy release in the fuel tube, the inner thermocouple should show a temperature rise above the outer, the temperature difference being proportional to the energy released. This could be calibrated, using dummy tubes with internal electrical heaters.

    More than one fuel tube may be tested at the same time. (Two could be easy, symmetrical). Controls are tricky, though, because the heat behavior of a fuel tube may depend on the contents. Nevertheless, temperature difference across a constant thermal resistance (the larger tube with mounted thermocouples) should show direction of heat flow and could be correlated with source energy.

    In this design, the tube furnace is the constant-temperature sink for isoperibolic calorimetry. The heating coils are isolated from the fuel tubes, and should there be XP, it would not directly affect the tube furnace heating coils. It would take major failure to damage the inner thermocouple, not in contact with the fuel tube. If that is a problem, there could be an additional cylinder containing the actual fuel tube.

    The basic idea of heating fuel and control tubes with the same power and observing temperature differences is sound; but there are details. Not only should the power be the same, but thermal mass and position in the environment can matter; that is, ordinary cooling should be the same. To be conclusive, controls should be employed, under conditions as identical as possible to the experimental runs.

    The interior of a microwave oven is not uniform in energy density

    There are ideas being promoted that tube failures are due to sudden, massive XP. There is no evidence for that. In the recent Vasilenko experiment, the Kanthal heating coils were covered by a layer of alumina cement, ostensibly to protect them from air. In fact, Kanthal is stable with exposure to air, but may or may not handle hydrogen. The difference in expansion between Kanthal and alumina is likely to cause the observed alumina cracking, and the Vasilenko design, which is similar to Parkhomov’s original design, the thermocouple will not get as hot as the heating coils, especially because they are covered with ialumina cement. Vasilenko’s image shows white-hot heating coils exposed through cracks in the alumina, yellow hot alumina above that, and a duller-yellow thermocouple/cement assembly. The coils are far hotter than the thermocouple, not from LENR, but simply from how the device is constructed.

    The empty control tube was mounted differently, in a way that might cool more efficiently, thus the measured temperature difference as power was applied. That this difference appeared at low temperature, and was maintained proportionally with increasing temperature, is a clue that there is little or no LENR here. Heater failure, then, could readily occur from the Kanthal getting too hot (which is possible, and which would happen first with the fueled reactor in this setup), or from stress induced by alumina cracking, more so if the tube fails due to internal pressure from released hydrogen.

    It appears that alumina will absorb microwave energy. The frequency would matter, and heating uniformly within the microwave oven may not be simple. There are apparently thermocouples which can be used in microwave ovens, but they are not high-temperature ones. It’s tricky.
