Thermal Paste

Hello, I was wondering, if you had tubs of high temperature thermal compound, would putting it on your stove-top (flat topped stoves, not the ones with the coils) before you cooked let your stove be more efficient? Other than the fact that I don't know where you would get high temperature thermal paste that could withstand your stop-top and the fact that it would probably ruin your pots, pans, and stove, is it possible? I wonder because I just saw my tubs of thermal paste sitting there and then went inside to cook something.

A Thermal reacting LED? Answered

Ok so I don't know much about LED's, or let alone anything about how electronics work, then only thing I know is how to code on a computer, for a computer, I don't even know how to code a PIC card or whatever... But anyway, I want to make an LED react based on a thermal image, so its camera or Thermal LED or something detects heat in a room and adjusts the power of light on an LED and also turns it off and on, kindof like another tutorial that someone had with the light table, except they didn't have instructions to build it. If you want I can draw a picture of what it should look like, but basically I want to end up with a bunch of LED's to light up when i enter my room, and later on I want to make it so that they shut off when I clap 2 times and make them udjust different light areas, so when I walk in different areas of my room, different lights go on, and then later after that I'll make it so I can change the colours of the lights by saying a different colour. If someone can help menu would greatly appreciate it and when i build it I will post the instructions on this site :D Thankyou

Question by Jayvis Vineet Gonsalves  

Thermal Cooling and Heating

It is very possible and it is in use today by using Thermal Cooling and Heating from the earth. Performed by using a 6" well at least 100' deep, with thermal tubing inserted into the well carrying the liquid to be cooled/heated. Process is done by a circulating pump in the interior unit - through the coil - sending back through the well system and returning. It starts out from the main unit circ pump.......through the coils.......out to the "down tube" into the 6" well pipe, a sharp 180* turn back up the system returning to the circ pump. Such a system is used by many facilities to Air Condition or heat rooms of about 15' x 15' or so. I have even seen a system that utilized creek water as the "cooler" of the tubing on a circ pump system. That one really was cool, about 52 degrees. Have you heard of these systems or seen something like it or close?

photovoltaic or solar thermal? Answered

I've been designing a high tech, off grid, self sufficient home over the past few months as a hobby. So far it consists of an artificial island floating on recycled plastic bottles and other buoyant devices (see: Spiral island) with an average sized house made of recycled shipping containers and plywood with a greenhouse. I basically want it to be a more high tech version of Spiral Island, but I have two questions. 1.) I'm trying to decide on whether or not I should use a Solar thermal generator or an array of Photovoltaic panels, but which has a better efficiency rate in terms of power and cost? 2.) Does anyone have any suggestions on plumbing? cause so far all I've thought of is a self composting toilet, but it would be really cool to have running water.

Thermal insulation/cover for heating water bottle

I am building a water bottle that can heat water inside up to 80 degree Celsius for my engineering project. The design of the bottle is as follows:1. an aluminium or steel flask2. heating coil at the bottom of the flask(for heating)3. battery and circuit for the heating coil is located below the heating coil.I want to design a cover such that a person can hold the bottle when the water is hot. Also, i want to protect the circuit and battery at the bottom from the heating coil. How can I do this? (As of now, i was thinking to spray polyurethane foam around the bottle and use a plastic cover. Also, using a polystyrene board below the heating coil to separate it from circuit board/battery). Are there any other insulating materials that can be used? Considerations for cover and insulation: 1. Should be able to hold the bottle 2. Wash the bottle (hence, waterproof)

Copper tape for thermal concentration

Has anyone ever used copper tape to concentrate heat on an object to obtain a uniform higher temperature?   I've been doing some studies in the recent past that suggest polished copper foil is a good reflector of infrared energy. It is not as good as silver, but I don't think it would go over well to use silver in any sort of oven or kiln.  I used to think good ole aluminum foil was good for heat, but it turns out it is only good for stopping heat.  I've thought of using the instructable on the waffle iron or make one by way of a bread toaster, but will most likely not be able to go through with it.  The copper foil is the same type found at stained glass craft shops.

Lighting with RGB LEDs

Hi all. I am wanting to get into using led lighting for long exposure photos (for the purpose of thermal imaging) and I am looking at RGB LEDs for providing the colour. My question being, should I try finding LEDs that have similar light output in mcd or stick with RGB LEDs? The reason I am asking is when I am looking at specs, the green seems to be 2 to 4 times as bright. Is this an issue?  Also, the RGB LEDs seem to have a much wider viewing/ lighting angle.  I am not sure where to go from here. Any help would be appreciated.  Thank you all very much for the time.  Professorred

Thermal conductivity of two welded plates?

I am in the process of building a wood stove (details on FE Blog) mainly from scrap metal, but I have got it into my head that a stainless steel hotplate would be nice. I wanted one 10mm thick, round with a diameter of 390mm. As it turns out 6mm seems to be a bit of a threshold for stainless, and anything over has to be laser cut or similar and is loads more expensive. Like £80 is the cheapest I can find it.  Anyway, one solution would be to buy two 5mm thick plates and weld round the circumference - that seems like it would work out quite a lot cheaper. The question is how would the thermal conductivity be affected by the tiny gaps which would inevitably remain in the centre (the two plates will never be completely flat)? Is there some kind of thermal paste that could mitigate this, which is very heat resistant? If so how would it deal with being superheated by the welding, and would it contaminate the weld? And lastly - this got me to thinking about copper bottomed pans - how do they bond the copper to the stainless steel (google is failing me- or I am failing google with poor search terms)?? So 3 sort of related questions: 1.Welded plate- big conductivity problem or naught to worry bout? 2.Super high temp. thermal past  - would it help? 3.How are pans copper bottomed anyway?? Thanks, Bongo

USB heated Gloves mod Qs

I recently received a pair of USB powered heated gloves. Unfortunately they have a big bulky switch that hangs too closely to your hands and dangles around when you type. I'm looking to mod the gloves to have a less clunky switch, something more streamlined. The gloves have three setting, High (II), Off (O), and Low (I). There's a pic of what the inside looks like. I'm trying to figure out how the circuit works. I would assume it was just one setting is full power and the other has the resistor in it, but the resistor appears to be soldered to two leads on the switch. Does the wiring of it mean it skips the resistor when it's in the high position? Also what type of resistor is that (the big grey type) can it be substituted for a smaller one of equal value? It's not that important, I'm just curious, because I think I'm actually going to make the mod only have the High setting and probably without the switch since I could just unplug them instead of adding in a switch.I think the heating elements might be wired in series because the top pad doesn't get as hot at the bottom (or maybe they're just different temperature pads?).And I'd like to add a battery pack option. What would be the ideal (smallest) batttery setup I could use? (5 volts right?) Would a 9v battery overwork the thermal pads or just make them hotter?I was also thinking of changing the connecttion to a connector like this (LINK) a might be a little smaller, thoughts? Also what wires on the USB are pos and neg?

Hidden dangers of receips and dockets printed on thermal paper

Ever wondered how these thermal papers for your fax machine or supermarket docket work? Nothing that is printed by fast machines for you these days uses ink when it comes to cheaply producing a parking docket for example. If you played around with these papers you already know they turn black when you apply heat. A soldering iron at low heat makes a nice pencil on them... But what if you pet or kid loves to play with these papers? Often they like do just jast with the receipt for your fast food if found inside the bag ;) Most people would not consider a piece of paper as a health risk, but for thermal paper this can often be a different story. A lot of these papers still use bisphenol in one form or the other to develop the ink from crystal clear to black. Feel free to read up on it on Wikipedia - I recommend it! They also have more info on the thermal paper itself, including alternatives to bisphenol. Although recent studies are in favour of the thermal paper, when handled correctly some also show an increased risk for those dealing with a lot of paper - like the people working at cash registers in a really busy shop. Bisphenol can get into the body through the skin and by ingestion - for example when your kid tries to chew on it. As noone really knows where the paper you got came from it is a guessing game to figure out if it is free of harmful chemicals... So the best option is to avoid exposure when possible. If you know your kids or pets might to try eating some paper then make sure you don't leave any thermal paper around where they could reach it. But there is good news too as more and more countries try to set standards for thermal paper in regards to harmful chemical levels and protective coatings. Cheap paper for almost any priter out there can always be ordered from asia to avoid higher costs of local and safe paper though...
