Ok let me pin point my question - what is the temperature rise I can expect to get out of 100 grams of dry zeolites and 100ml of water at room temperature, mixed together?

So, I was reading about zeolites: https://en.wikipedia.org/wiki/Zeolite One of the things it is used for, is in the heating industry, namely: "Zeolites can be used as solar thermal collectors and for adsorption refrigeration. In these applications, their high heat of adsorptionand ability to...

So, zoki85, if I were interested in making an aluminium disc floating using oscillating magnetic field, instead of the gyroscopic stabilization which the levitron employs, I should use more than one electromagnet? do the electromagnets need to be in operated in some sort of phase or opposing...

zoki85, first of all thank you very much for taking the time and replying to my questions. Second, I hope you do realize your replies encourage me to ask more questions :). Why would there be a difference? Why would the levitating electromagnet on top of an aluminium base be more stable than a...

I see. I've actually came across the link you shared in your last reply while researching the subject. However, I've found this video on youtube: It looks like a reversed form to what I'm suggesting - just that this time, the aluminium is a large base (1/4" thick) and the AC electromagnet (36...

Ok, can you please explain why? as this is unclear from the wikipedia article you've linked to. And what would I need, to make this stable? Regards, ErikL.

Zoki, thanks for your reply. According to the wikipedia article you've linked to, under Stability>Static, it says that: . So, should I gather from this that the device I want to build falls under the definition of "simple AC driven electromagnet" and will levitate the aluminium disc with...

Hi all, I'm new to this forum as a member, but have come across some of the topics here via google in the past. I'm trying to build an AC electromagnet levitation device, to levitate a small piece of aluminium. My knowledge in physics is limited to popular science and interest, but I am pretty...
