It would be cool if you could design that compound parabolic to flip over that picnic table like an umbrella when not being used... sort of duel purpose or at least an easy storage option just flip it over like a roof.
@trentontrading ironically, that is exactly what happened to the larger piece, then I moved and it became scrap parts for something else... lol solar cooker still working great though!
@viking1au yeah I agree... i made this before most people have smartphones and convenient video cameras...lol anyway... thanks for posting .....for some its better than nothing...
When I was a UN Peacekeeper in East Timor I made one like yours with instructions from the internet. I used the foil from dinner trays from the kitchen so it wasn't wrinkled and I gave it to our interpreter for his wife to cook rice each day. Needless to say the locals where impressed as they knew nothing about solar cooking. They are fun to make and use. Thanks for the video
@zacandmillie Im very glad it is useful! I just made slideshow video on a whim to document my progression and then posed a few videos of it cooking... they really do work... unfortunately I moved and buried projects but I plan to make a better improved video now that I have a good camera... someday! lol
@tinidor2008 this is why a well constructed parabolic is good opposed to lets say a lens... since you can contain the focal point inside the parabolic... it is dangerous however to pickup a pan thats been sitting in it without gloves! lol I KNOW! lol
I just watched your videos on this..I was wondering if you could post the dimessions. Have you done any adjustments or have any other ideas on making it a better cooker?
I have some new ideas coming this summer... Ive been researching other energy capturing devices and of course work...lol also recumbent bike designs... this summer I hope to have more working concepts with video instead of slideshows!
I made a "Solar Design T-Square". Basically the problem with parabolic is that you have to move the darn thing all the time to follow the sun. A few degrees of sun movement and much of the light misses the cooking pot. The T-Square shows that different reflector shapes should work better. One of your solar cookers is a DATS? They have a very good reputation. They are not quite parabolic and are designed to cook for about 2 hours.
Did you get this one to work properly? I´m sorry, but this shape looks highly inefficient, I built the same one, but curving the cardboard, trying to resmble a paraboloid, that´s the idea. (The box is actualy worse!).
Works Great for what it was.. I have cooked chicken and rice, fried onions ect... it works very good.. one secret is sealing the pan.. I use oven bags and I use a dark pan to absorb the heat... cast iron is nice but takes too long to heat... the point of the video was just a test and a successful one that with this foam core insulation and a couple hrs you have something that stays cool and weighs nothing and works!
Its just a study in solar parabolic designs... you can use it to culminate light to make a solar cooker... watch some other videos of mine where I use it to cook food... ive hit 400deg in this thing!
its Aluminum Duct tape... it is very reflective... you would use aluminum foil to bring cost down but this tape applies SO much easier.... the backing of the insulation fiber board is also a metallic material... it really was not necessary for this build since it is on the outside but you could just us that side.. works but not as well as the aluminum tape...
Terrific idea will work fersure, but I just cannot accolade still pictures in youtube videos. I could read a book with pictues just as well. Nevertheless thanks for sharing the IDEA.
Hahaha... well the square reflector box was an afterthought and I do not use it much... the parabolic works fantastic! I have a few videos here or it working... lol I stil dont know what to do with that huge Square box... storage that is...lol
haha yeah... its a little too relaxing I guess...lol but it is the story of a dying electric grid and use of fossle fuels for the free and abundant solar... lol so.. I guess metaphorically it is a funeral and rebirth... maybe I should have pics of a gas range and electric bills at the beginning and a 2 parter with more upbeat music for the coming future events! :D
But in a parabolic or loook like, the focus of the sun light, where the heat gety high, is not the botton of the parabola. So how that will focus the sun on the food?????
It comes with a semi reflective back from LOWES or Home Depot or similar ... but it is not nesseccary... just use aluminum tape.. that is ice and reflective and easy to adhere to surface... I used the foam board but there is a fiberglass board with more reflective properties.. but I have not used it and not sure if it is as bendable... total cost for this project including the box knife is about 25 bucks... amazing! Music is piano music style from Jim Brickman...
Good video. Does the insulation come with the reflective coating or do you have to add that yourself? All I've ever seen is the white, pink or blue foam, but not reflective.
BTW: What is the background music? It's very pleasant background for a slide show.
a study in solar collecting... I built it from reflective insulation board .. in bright sunlight it can focus light to about 400˚F and cook food easily... about anything you would want to cook... check out some other of my videos... Ill be running a steam engine or Stirling soon off of this or similar design

aluminium tape from a hardware shop, or fake chrome decal material from an automotive shop work best, thinner is better to negate bubbling
