You said I was a nutjob with my real world examples which are easily falsifiable, but I know you won't falsify them ;D In fact, I tried it for fun at work yesterday. As predicted, a metal ring heated to 150F was placed on the colder granite plate and the end touching the plate rapidly cooled while the side facing up did not. Neither did the outer edges of the part near the granite plate get warmer.
I then repeated the process by suspending the part ~1mm above the plate. Gee Iceskater, for some odd reason the face of the hotter object toward the surface plate still cooled while the side facing up remained warmer.
And no Iceskater, granite has no special magnetic properties. I can use a steel surface plate, aluminum or whatever you wish, the results won't change much. Now you post this again as if it is meaningful.
You actually expect anyone with measurement experience not to question your process attempting to discriminate 1.2c ? Your hand is a heat generator; you are burning calories to create the heat which introduces more heat into the system. Instead, use a plate with sufficient mass warmed to your body temperature, then place it between the two surfaces and report the results, but use a higher temperature differential.
I suspect we'll get treated to another long diatribe saying how smart you are and how stupid I am. I now owe Numerouno an apology. At least he did not patronize others by trying to humiliate them with a strawman post.
Fear not Iceskater, I talked to our CAD guys at work to see if Solid Works has the thermo module to simulate my scenario. Will you then create a post explaining Solid Works new theory of radiation?
My example was not intended to disprove the "greenhouse effect" and yours definitely does not validate it. I'm not even saying I agree with Icefisher. All I did was report 30 years of observation, which you ridiculed.
Finally Iceskater, let's dispense with the semantics game. My saying the plate "sucking" the heat from the part is common jargon in these circles.
Magellan
I am glad you tried the experiment. This is science in action and the results will speak for themselves.
1. I did my experiment with a freezer and because Iceskater objected to me using artificial cooling i used the same kind of set up using the cold wall.
I have tried also using an electric kitchen hot plate and an oven tray with cooling to a coldish room and that worked well. I wanted however to get closer temperatures to earth and the atmosphere. I also tried a room temperature plate but i thought the hand was rather elegant.
2. I can produce another video using a plate as you suggest.
3. I am not happy with your heated plate being so close to the granite. The possibility it can alter the results is definately there. You dont need to have the plate so close to the granite. As long as the granite can shield the cold of the furnace wall it will be ok
4. You supplied no temperature information about the furnace walls. Ultimately they have to be sufficiently colder than the granite for this to work. The idea is hot warm cold. So three surfaces and then swap the warm plate in and out to see the difference.
5. As i said last post i am not sure you understand the nature of the experiment. You need those three different temperatures of hot warm cold
6. If your granite is as cold as the furnace walls then it should still work to raise the temperature of the metal plate, as your heated plate
must cool via its surroundings.
7.
There is no way that a cold mass can radiatively suck the heat out of a hot mass unless the granite is colder than the furnace walls. Again furnace wall temperature information is needed to clarify what is going on.
8. Is the furnace wall totally clean of metal and dust? Either way you need to test the furnace wall temperature when you turn the furnace on to see if it is self heating. the whole point of this experiment is that the metal cools to a very cold surface.
9. How big is the furnace?
10. As i mentioned in the other post to get rid of all experimental uncertainities it would be better to use electrical heating inside the vacuum furnace. A light bulb painted Black should do it for the heater and provide just sufficient to warm it. All you need is reproducibility for middle plate added and without it so you can demonstrate you can get the same temperature for plate only scenario before and after you have tried the second plate.
11. But again i want to emphasise the idea of this experiment is that the light bulb cools to a cold surface and you add a middle temperature surface that then is heated by the lightbulb
12 as for me ridiculing you, you made some observations about apparantly putting cold metal into a hot furnace, apparantly between a hot furnace wall and the hot piece you were annealing that to me seemed very naive. Radiative heating would be very significant in an ordinary furnace and you would have blocked that with the cold metal.
My comment was what do you expect?
Yes i thought the idea that a cold object sucks heat out of a hot object to be a silly one. I cannot see that has any basis in science and you dont seem to have used it only as a figure of speech at the time.
a cold object in space with a warm object heats the warm object at all times unless the cold object is at absolute zero. The hot objects heats the cold object more however for a net heating by the hot object.
That is just basic heat science as put forth for a very long time.
And now you just said
As predicted, a metal ring heated to 150F was placed on the colder granite plate and the end touching the plate rapidly cooled while the side facing up did not. Neither did the outer edges of the part near the granite plate get warmer. Magellan this is a
radiation experiment. If you place a hot metal ring on a cold piece of granite the heat from the metal will
conduct into the granite and rapidly cool the metal.
The metal plate cannot get warm until the granite is warmer than the furnace walls. So i have no idea what you actually did as you have not given temperature information about the granite or furnace walls.
Air conducts when there are very thin amounts of air.
I asked you if this was a vacuum induction furnace
Did you read the last post i made here??
So the saga continues for a while yet
You obviously think i am a fool and you are obviously a bit upset with me. I would not say you are a fool - i just dont think you are thinking about this so clearly.
And you have made claims about my process that are unsupported by the facts.
Twice you said i had not answered you about the greenhouse effect
And you said i was just abusive and had not provided experimental evidence, when i had.
I was also dealing with icefisher for almost two weeks who was persistantly rude with me and Steve.
Then you arrived to support Icefisher.
The idea is not to upset you. Science is what matters here.
The new video will be ready in about 12 hours.
