    Magnetic shielding using a semiconductor?

    I read an article a week or so ago talking about using a semiconductor to disrupt a magnetic field. Generally a magnetic field can be disrupted by any magnetic material in its path. Steel for a basic example can reduce the realized field on the opposite side from the magnetic field source...

    Thin ceramic plates sources / manufacture techniques?

    It's just in my mind that, similar to an oven, you need an insulator to keep the hot air in. Instead of say just leaving the door open, you close the door and it keeps the heat intact. I need to make sure to keep the heat to it's side of the enclosure. It's mainly just insulation. And there is a...

    Thin ceramic plates sources / manufacture techniques?

    I need to insulate the area between two heat sinks. The gap is about 10mm, and the bottoms of the heat sinks are facing eachother with a peltier chip sandwiched in-between. However the two sinks are in separate enclosed sections, and I need to insulate the hot side from the cold side as much as...

    How to transfer cold energy instead of heat?

    That's more or less how I have it in my head so I'm glad you said it. I appreciate you guys weighing in. Hopefully this little setup can get the desired results. I guess all I'm making in the end is a tiny airconditioner :)

    How to transfer cold energy instead of heat?

    I have a little enclosure that I need to drop the inside temperature of somewhat considerably. My idea is to blow this cold air through the heatsink on the cold side into the enclosure and pull cycle the inside air out of the inclosure and through the hot side heatsink to dissipate the heat...

    How to transfer cold energy instead of heat?

    How to transfer "cold" energy instead of heat? My question is pretty basic. I am looking to radiate cold with the same concept of heat dissipation. For example on a peltier thermoelectric module gets hot on one side and cold on the other. A heatsink will help dissipate the heat from the hot...

    Airflow inside a computer tower.

    Jesus Lord!! lol. I dont think I have ever seen one that bad. Of course most things I handle are in "clean" environments like data centers, but dust can still build up, but never like that. I guess We could say some kind of filtration would be needed on the case but then we are back to the...

    Airflow inside a computer tower.

    I think the main problem is actually the fan input to airspace ratio. Meaning when the airspace drops inside the case, the pressure increases and causes drag on the fans. So if we take the same amount of fans from a large tower on a small case, the fans will actually turn slower because the...

    Airflow inside a computer tower.

    I attached an example image of what I mean. I cannot imagine any scenario where example 1 is better than example 2. I am also very familiar with computers. I am a system designer / builder for high load workstations and servers. I use water cooling on most everything as its almost mandatory...

    Airflow inside a computer tower.

    It seems to me though that passing the same amount of air into and out of a smaller enclosure would increase cooling efficiency. Lets say with our fans we can achieve a steady 6 cfm of flow through an enclosure. Since the smaller enclosure has less airspace, it should cycle new air through at a...

    Airflow inside a computer tower.

    I had a question and I figure you guys are the best for the task. I was wondering if theoretically you had a standard computer case, would you benefit by reducing open airspace in the case? Lets say just for example you could place a cube inside the case that doesn't touch anything, it just...

    Earths Magnetic Field and solar winds

    Do you mean to say that a this strong magnetic field can create gravity from little to no mass? If by the general relativity theory you mean that gravity will be playing a role in this, I was not aware magnetism could alter or create a gravitational field. Or can magnetism curve space time by...

    Earths Magnetic Field and solar winds

    Since the earths magnetic field helps to protect the earth from a lot of the suns harsh treatments, do we also assume that in some degree light is also (possibly in very small fractions) also diverted by the magnetic field? If no, would it even be possible to assume that a very strong...

    Spinning Magnet Question

    Lets assume for a moment the spinning problem has been resolved. No issues of the system or the magnet being unstable. Thats more of a mechanical problem, but I am not really interested in that. Anyhow this is more of a theoretical question. I dont know of any reason this would actually be...
