Ok i have moved into a new studio which does not have an external vent fitted to the cooker hood and relies on a re-circulation kit comprising of a small tower and a disposable carbon filter (which can cost quite a bit to keep replacing). So what i was thinking was how about ducting it to a homemade condenser, something simple like a plastic container with a cut off of hood filter attached to an area near the top of the container and the vent ducted in through the top of the container it could be primed with an inch or so of water to get the process going..... i recon my concept is pretty basic but am i heading in the right direction?

Hi,I was invited by GoWithFlo to add this project to the FullBellyProject group. From my understanding this group would be an ideal place to discuss improvements to the design and more importantly test it in the field.Please don't hesitate to ask any questions and provide any comments!Thanks!Kevin.

Https://www.instructables.com/id/HELIOSTAT/First of all thank you especially forgesmith for your help. Now is the time for the replacement for the rubber bands (to split the distance) in the plan. Any ideas? My twin spools that retract like a tape measure can work. Also 2 "geared" wires with a gearwheel in the middle would work. The centre of the reflector be joined to a piece that passes through the gearwheel.(I will draw it later!) Anyways, hope to get some answers. Thank you BrianThe part of the question below has been answered!Basically i have to attach the reflector so that it can swivel round the mounting.The way old farm tractor 3 point linkages worked on the back would be perfect. The side arms have a little ball in them and you put a shaft on the attached plough or whatever through a hole in the ball and fasened it with a clip. Imagine the reflector in place of the side arm and you have a perfect attachment BUT there is probably a modern urban alternative. Can you think of one?I am in no big rush myself because I have a big work project to complete but suggestions would be awesome for the near future.Thank you Brian White

Panel cookers are simple solar cookers that are made by folding cardboard. When folded, sunlight shines on the panels and gets reflected to the cooking pot. (Normally the cooking pot is painted black and it is often covered in an oven bag to keep heat in better). But, I have never seen a picture of a panel cooker with the side folds in towards the cooking pot instead of out away from the pot. My tests indicate that it will cook for a longer time if you face the side panels in. Anyone want to try it? Also, the tests in software show that a normal panel cooker might give better if it was made with a long tail in line with the path of the sun. Would you like to make small ones and compare this to a normal panel cooker? Small ones heating pint jars of water might be very good for comparison. I have too much cloudy weather to do this. Also, do not worry too much about parabolic. A part circle is just as good for solar cooking and the important thing is to have the axises of curve (Perhaps there is a correct word?) of the troughs or panels at right angles to each other. Brian

I have a new instructable (Late December) about making your own templates with technical drawing tools. You can basically make the compound parabolic dish to catch 1,2,3 or 4 hours worth of sunlight. I have made a 3 hour dish and it worked great as a solar cooker. I have not however solved the math for exactly how the light reflects to the cooking pot. It is pretty good but not yet optimized. Would anyone like to join in? I can either make the instructable a collaboration or you can post your refinements on appropedia on their wiki.I do not want this project to lie stillborn like the pulser pump did for 20 years but how to engage people? Thats the real problem. Thank you Brian White 21st dec 2008 and it has worked really well. I would like others to try it so I made a template. I chalklined across the dome at 15 degrees intervals, Put clear plastic over it, marked the lines on the plastic and cut the plastic. Basically all you have to do is cut a piece of ply to be like the template, use it to cut out 12 mylar segments and then tape them together. (I do not know how you will hold this umbrella open, thats up to you!)My dimension lines were vertical on the paper, it just looks angled from the picture. Figures (all in inches) are 0.5,15.5,17,31,7,12,2.5 and 3/4 just in case you cannot read them. Its a funny looking template but I think it is good enough of an approximation for this. I devided the 2 long curves into straight lines.Should be fine. I also have a pdf file containing results, etc as the second image file. Just click on it and it should open.

It's going to be one of those with a box chamber with gathering panels. Should the inside chamber of a solar oven be black, to absorb the heat, or should it be reflective to make sure that the tray and food are the only things that absorb it? What shape should the chamber be?

I have being doing limited testing of the combined trough shown below and it seems to work as expected. I used a 4ft by 8 ft piece of corrugated plastic for the big trough (too wide but I was reluctant to cut it). Compared to dishes, this was incredibly easy to make and actually gives more reliable concentration over a longer time period. Would anyone like to try it on tiny demo scale? (I mean something tiny made with 1ft by 2 ft paper perhaps) see if you can make a panel cooker with the design as a template? I think it will work with hemisphere curve, or parabolic curve, any curve or panel cooker shape that shines the light on a cooking vessel. Key points. 1 The troughs must be curved in directions that are at right angles to each other. 2 the long primary collector trough must be in line with the path of the sun.And thats basically it! The primary trough concentrates light in one plane and the secondary trough (the little wings round the red pot) concentrate it in the other plane. I then tried to get software to show if it was any good and It seems to show that it would cook for significantly longer than a parabolic dish. But the software showed that it was not as good as I had hoped. From running the software (art of illusion) I came up with the kyoto trough as a possible solution.The kyoto trough is a trough made by taking 2 halves of a parabolic trough and twisting them a little inwards roung the focus. This can focus all the light between the focal line and the bottom of the trough for a time period coresponding to the angle of twist. 15 degrees of twist coresponds to one hour. http://www.youtube.com/watch?v=uX9Z-nsUHiA. That is a really useful property because it confers reliability. The next part of the kyoto trough can just be an ordinary parabolic trough to do a final concentrationof the light onto the cooking pot. Well 2 small troughs to deal with 2 streams of light going towards the cooking pot from either side of the trough. Are any mathematicians interested in resolving the troughs into a Kyoto Dish? which would give much longer cook times than a parabolic dish.Brian

Is there any reason you couldn't use an older (non-digital) slow cooker/crockpot with a Lutron dimmer cord? We use the dimmers on all our bedside reading lamps, but they're rated for up to 300 watts. It would take some experimenting to get the temperature right, then I think I'd tape a "stop" on the slider switch at that point. Any thoughts? Raising the food from the bottom of the pot? An upside-down silicone cake pan, maybe? Or suspending the bag somehow? I already have a Foodsaver.

Our Kiwanis club has a roux party every year where a dozen or so people cook roux in cast iron pots over gas burners. Hours of stirring of various liquids, veggies and spices (added at intervals through out the cooking cycle). Cooked until it becomes a solid about the consistency of moist turkey dressing, to be dipped out into a pan and then start a new batch. What we need is something like a small cement mixer with burners. Something that will heat liquid, mix, and dump or we can scoop out when it's solidified. The stirring needs to be constant hence the cement mixer premise. If it doesn't mix well and parts of it burn then the entire batch is ruined. Electricity is available, propane bottles for fuel. Tried thinking through something with two metal cylinders, one inside the other with the gas jets between the two but the rotation part is the issue. Any help will be appreciated, and of course since we are a small nonprofit the cost needs to be as low as possible. Thank you ! Tray10

Having seen the microwave transformer welding kit and similar projects I started wondering about this one... Induction cookers are basically one side of a transformer and usually just dissipate current in to the pot to heat up the pot. But they've a high number of coils and I've seen them rated at 3000 watts, so if you made a coil that was a few turns of thick wire to be the other side of the transformer you'd possibly be able to have a huge current low voltage supply similar to the microwave oven welder. I imagine there'd be safety devices that may need disabled but the idea of your oven being a welder seems cool to me, especially if someone had a need to weld often and their kitchen was through to their garage.

We've had our second rice cooker fail (this Black&Decker; rice cooker replaced an Aroma rice cooker which failed). What happened was it started to stink and didn't cook well, then finally the thermal cutoff inside failed. I've already had the exact same problem with the previous Aroma rice cooker... let me explain: In that Aroma Rice cooker which failed, I replaced the thermal cutoff with a direct connection and it worked! Well sort of... It actually overheated all the time, but didn't heat the food very much. Inside the connections I had made were melting/burning and it was always stinking, so of course we did not use it anymore. So this means there was something else wrong with that rice cooker. It overheated for a reason, and removing the overheat protection caused it to overheat. Rice cookers are very simple, so I have no idea what the problem was (and is). The only suspect is some weird rectangular thing i've seen, where two wires go in; one to the switch and the other to the element. So with this Black & Decker rice cooker, which has been working for quite a while (maybe a year or two), it finally failed by overheating the same way the old rice cooker did when I removed the overheat protection. It stunk a bit and didn't heat up well, then the thermal cutoff broke and it became dead. Replacing the thermal cutoff won't fix it because it would just overheat again. So what is wrong? Is it that rectangular thing? I opened the rectangular thing... inside there is a sandwich of materials and a wire... The first layer is the top metal cover which covers it up (and also always becomes rusty). The second layer is a thin papery insulator (or I think it is). The third layer is the same kind of insulator, but cut and it has a thin wire wrapped around it connected to the two wires going to the whole thing. The fourth layer is another insulator like the second. And the fifth layer is the metal frame which all the previous layers sits into, and the frame is bent around them to hold it together, and it has a screwhole to attach it. What is this thing? Is it some resistor? Does it increase resistance as it heats up, to regulate the temperature? And could this be what failed?

The idea behind the Kyoto Trough is to use a parabolic trough (rotated inwards round its focal line) so that all the light it collects over a certain time (1 2 3 or 4 hours) focuses BELOW the focal line. Then you use other troughs (probably facing at right angles to the first one) to concentrate this light further onto the cooking pot. I have done a rudimentary test in software and the concept does work there. I think it will also work as a panel cooker. It is very important to line up the primary trough with the path of the sun across the sky. It should also work as a panel cooker. Just a much longer panel cooker with the v shaped little wings like in the diagram Or perhaps a panel cooker with just one "tail" going up in the air and insulation on the back half of your cooking pot? (taking away one half of the device) Thanks Brian

I just made an instructable and entered it in the green competition. Way too late of course. the picture shows the generic driver of a battery wall clock. I have adapted one by removing the 2 concentric pipes in the middle that run the minute and second hand to just leave the hour hand driver that i use to drive a "gear" wheel. Anyway, the idea is to do a little dismemberment of clocks, and use the little drive mechanism to control the turning of a solar reflector to continually have the sun focused on what you cook. My current edition of it seems to be working. I believe a simple tracker is sorely needed for solar applications. Once a reliable one comes on the market, you may see new backyard applications popping up. For instance, I cook soil! I stick it in a big black pot, and steam it in my tracking solar cooker for a day. This generally reaches 60 or 70 C (It is a big pot and soil has a low thermal conductivity) which is enough to kill seed eating bugs and weed seeds. I end up with excellent home made seeding soil. Solarization is also possible. Again, a big pot or can, put in all your rotten insect infested fruit, cook for a day, and next year, less bugs on your trees and less sourse of fungal infection. It might even end up as a stage in the processing of compost. Lots of weed roots and seeds survive the compost heat. But they might not do so good after a day at 70 C! Tracking might even be accurate enough to make quicklime! Quicklime is made from limestone CaCO3 that is heated enough to drive off the CO2. You then slake the lime (add water) and it gives off a lot of heat. Heat storage potential? and you have Ca(OH)2 which is the basis for lime plaster. Parabolic dish concentrators can get hot enough to cook limestone. but I do not know the details. There is more of but that will do for now. I hope people try this and prove to the holy free market that simple trackers are needed! Brian White

Its cane harvest season and the railway pickup lines are littered with pre chopped sugar cane stalks that fell off the carts while loading, also every road side creek is surrounded by sugar cane which is unharvestable and for all intents and purposes, as useful as grass, so with either nobody will object to me taking them. Especially since its all on public property now anyway. Now, i want to produce as much ethanol as i can from a single batch using a 20L pressure cooker, the end use of the ethanol is for fuel, sterilization and cleaning, not drinking, infact i actually want it to produce more isopropinol alcohol if at all possible, iso is expensive and it would be fun to try to distill it out, or otherwise leave it in the end spirits. Now, i have no idea on how i can cleanly ferment sugar cane. Im going to ferment it sealed inside the pressure cooker, but first sterilize it as i dont want any other smelly volatiles to grow. also in the pressure cooker i can hook the pressure releif valve directly to the condenser. So, any idea on how i go about doing this? am i ok to just crush and chop the stalks and turn them into a dense soup, or is there a reason as to why i should need to juice them? Also do i need to add yest, and if so how much? This is as an experiment, to do it because i can and nothing more, im well aware i can easily go out and buy methanol, ethanol and isopropyl alcohol and make them that way, but this is a DIY site, who the hell here goes and buys something when they can make it themselves.

While i was at home depot the other day, i noticed that a thermostat from an electronic water heater could possibly used for (almost precise) sous vide. Temperature regulation (it goes from 120 F to 150 F). The question is, i need your minds to help me in collaborating on a circuit setup which makes this possible. Thermostat: Costs: $14 Plug to plug your slow cooker in: $3 Pump to circulate water: $10 Total Cost: (without cooker): $27 *Future Instructable Contents* -As the thermostat works through surface contact, Place the Thermostat near the top of the metal vessel. -In order to better stabilize temperatures, make sure the heater is near the bottom of the vessel. (we'll just use a heat plate or something like that) -Use a pump to stabilize the temperature better. -The knob just really requires better calibration. Hystersis: 18 Degrees. The million dollar question Just say i set it at 150 and the hystersis is 18 degrees, that means it will turn back on at 132. Especially with sous vide, Is all that matters is that the food stay at the top temperature, (say 150) and it can go to 132 as long as the solution as a whole never goes above 150? In theory, this setup will just require more time to to heat evenly and correctly.

We are remodeling our kitchen/living room and are without a place to properly cook food. We have been eating out a bit, but its been annoying to rely on restaurant hours and their food to survive. This is what I have and how I am limited. - various cooking utensils (spatulas, knives, bowls, you name it...) - microwave (pretty weak) - rice cooker (small) - Toaster - toaster oven - electric frying pan (9" and sort of difficult to get out and use due to how messy it can get) I am limited since we are using part of our garage as the "kitchen" area. But the power is limited here in that only one appliance can be plugged in at once. We tried two and the circuit breaker flipped. So we can only use one at a time. So if I want to melt butter for toast I have to melt it in the microwave, then unplug the microwave and plug in the toaster, annoying but its all we have for the next month(s). Also the space is very small, we have a counter that fits a medium cutting board, so imagine a cutting board and maybe an extra square foot as workable space. Can anyone recommend some food items we can make with these limitations. There are so many things posted, I found a few interesting ones like rice cooker pizza among others.
