Radiodynamometer

aarthrj3811 said:
The Crookes radiometer, also known as the light mill or solar engine, consists of an airtight glass bulb, containing a partial vacuum. Inside are a set of vanes which are mounted on a spindle. The vanes rotate when exposed to light, with faster rotation for more intense light, providing a quantitative measurement of electromagnetic radiation intensity. The reason for the rotation has been the cause of much scientific debate.

The End...Art
Oh my, yes. The cause of much scientific debate....

Let's not go into how this machine is a dead-ringer for your radio-whatsit. Let's dismiss it.

While we're at it, let's dismiss dowsing as well, since it is also the cause of much debate, very little of it scientific. ::)

Did you understand that?
 

Hey AF…Haven’t you been reading the forum lately. You guys no long rule the boards. You have been exposed. If you have nothing to say about Dowsing you will be ignored. We will continue to answer all questions. When we determine Who and what your agenda is we will take the necessary action. So if you have any more questions, ask some one who cares..Art

Awww, Artie grew himself a backbone! ::)

Necessary action....lol....

I've been exposed.....lol....

You still can't explain why dowsing works, Art, and I highly doubt you'll even be able to.

Why don't you get back to the item I mentioned? Too scary....? :'(

Both enclosed in glass, both use suspended thin metal sheets.... They're constructed in almost the exact same fashion.

How are they different, Art?

And don't just say "They don't measure the same thing." That doesn't tell anyone anything.

HOW are they different?

af,

Both the Crookes radiometer and the so-called radiodynamometer use suspended (or pivoted) vanes, but they work on different principles. The vanes in the Crookes device have one side dark, the other side light, and is propelled by differential heating of the air inside the chamber. It won't work in a total vacuum.

The vanes in a radiodynamometer (versorium) react to electric charge, not heat, and will work (even better) in a total vacuum. Unlike the Crookes, it doesn't continuously spin, just turns to align with the electric field gradient.

So, even though they look very similar, they work on entirely different principles. BTW, with the versorium, since the vanes don't spin, you can either suspend them (as Art and I have done) or you can mount them on a spindle (as Art shows in another pic). With the Crookes, you can't suspend the vanes, they have to be on a spindle.

Ahhh, okay, thanks Carl. I knew there was an answer to this, I just should have known a skeptic would provide it. :) Thanks!

If I didn't know, I would say Carl was talking about an L-rod.

Only if, for some bizarre reason, you believe an L-rod responds to an electric field gradient instead of gravity.
 

Hey Mike…I have been experimenting with intact coat hangers since Telepropector made his post. There is no way that they will close with out you knowing that you did it. You have to move your hands to much to not be aware of it. ..Art

Huh? Let me get this straight: A device that reacts to electric field gradient can only do so if it not an L-rod? Okay, I think I get it????? Gravity only works if the detector is not in a jar--no human is capable of sensing a force field by using an L-rod because gravity overpowers it? Are you suggesting the L-rod can detect gravity from the target? I seriously doubt this being that gravity is the weakest known force. But hey, I have an open mind. Please explain.

The versorium has a very lightweight and balanced vane that is mounted on (or suspended from) a very low-friction pivot. And it's in a jar so that air currents do not affect it. Therefore, it can respond to electric fields.

Have you ever noticed that a needle compass has a balanced needle mounted on a low-friction pivot? What do you think will happen if you snip off one end of the needle, just shy of the pivot? Do you think it will still align with Earth's magnetic field? Why, you don't have to believe what will happen, you can actually try it, and know. A case where an 10 minutes in the lab beats 10 hours reading nutty pseudoscience books.

An L-rod is unbalanced, heavy, and held in a hand that is unsteady. It will easily follow gravity when the hand is moved even slightly. Do you think a hand-held L-rod will respond to a static electric field? How about an L-rod made of steel... will it align with Earth's magnetic field? Another 10 minutes of lab time and you can know, instead of believe.

Hi Carl, I agree with you in this case.
