Nice, but you ought to save your money, we should all know within about a month when Stanford have successfully fabricated the millimetre baby Quencos.

When tests on them show a small current without an oven then bingo!

Anyone that thinks a toaster oven is not sufficient for this test is severely limited in problem solving.

1: Heat the tube and record the current and polarity. Let the oven cool down and rotate the tube 180 degrees. Reheat and record the current and polarity. Is it the same polarity? If yes then it works.

2: Place the tube on a rotating shaft and slowly rotate while heating. Does it produce an alternating current? If no, then it works.

Wow, tested in a toaster oven without expensive isothermal oven.

Really? So your tests in the toaster oven are ruling out ANY OTHER POSSIBLE explanation for seeing a current indicated on the instrumentation? 

Wow, your toaster oven must be really something. Do you put the meter in there too, so it's not acting as a cold sink for some thermoelectric effect?

Lumen:

Your comments are nonsensical.  You are implicitly conceding that the toaster oven is not an isothermal environment but you have a Lumen-inspired "work around" for the problem.  Just rotate the tubes like barbecue chicken and if they produce current in a variable-temperature environment then all must be fine.

Your "problem solving" is severely limited.

Absolutely! Yes for test #1 and No for test #2.
These are separate tests so they have separate answers for the true condition.

Do you doubt the tests ability to determine if the result is due to uneven heating?

Of course, there is always the possibility that just after you rotate the tube 180 degrees, the toaster oven will suddenly reverse it's heat flow direction just to mess with your test. (maybe it's a smart toaster oven!)

It may even rotate the heating direction to match the tube rotation in test #2 so only one side of the tube will get heat. Yes it's a magic convection toaster oven!

Or, maybe the tests actually work as described. (naw, this is impossible in view of the other probabilities)

Cold sink!, Yes, first show me one that uses the same wire type for both sides of the connection! Oh, and test #3, Swap the wires connected to the tube and repeat tests #1 and #2.

Where is the "Cold Sink "idea now? Gee, I don't see it!

All the equipment in the world does not produce a good test, analytical thinking is the best equipment.
