Willkommen, bienvenue, welcome, welkomEdit

Welcome to the Solar Cooking Wiki! We invite you to add new articles and/or contribute to existing articles and discussions.

If you are new to Wikia or wikis in general, be sure to visit the "Community portal" for an outline of some of the main parts of the site and a link to pages that tell you how to edit.

Image:Bowl2.jpg Edit

Hi Ashokraok; the image you uploaded, Image:Bowl2.jpg, doesn't have a license listed. Please see Help:Image copyright tags for a list of licenses permitted on the Solar Cooking Wiki, or ask me or Tom Sponheim if you need help. Best wishes, Walter Siegmund 19:57, 17 January 2007 (UTC)

Hi Walter, Thanks for the correction, I shall add appropriate copy right licenses in future.

Hi Ashokraok; you are welcome. I think sometimes the software misses the checkbox for the copyright license. They show up at more.../Uncategorized images. Best wishes, Walter Siegmund 21:04, 23 January 2007 (UTC)

Image:Aurovillebowl.gif Edit

Hi again; the image you uploaded, Image:Aurovillebowl.gif, doesn't have a license listed either. I've added the public domain license to this one and the one above. If that isn't right, just leave a message here or on my talk page and I'll change it. Best wishes, Walter Siegmund 23:32, 19 January 2007 (UTC)

Talk:Compendium of solar cooker designs Edit

May I please call your attention to the discussion at Talk:Compendium of solar cooker designs? You can add that page (or any page) to your watch list by selecting "Watch" at the top of the page. You can view any changes to pages on your watch list by selecting "My watchlist". See Help:Talk page for more on using talk pages. Walter Siegmund 20:13, 26 January 2007 (UTC)

In the section titled 'Cookers which concentrate light from above' the entries for Pannel Cookers and Funnel Cookers both link to this page: http://solarcooking.wikia.com/wiki/Concentrators_from_above – which does not include any information about them. Are there pages for these cooker types? if so, where? Also, should they really be in the 'Cookers which concentrate light from above' section anyway? Cheers, Jonathan

I think you should add your full name to your user page. Edit

No need to reupload images Edit

If you see an image on one of our wiki pages, you don't have to reupload it to use it on another page. Just go to the page where you see the image and click the Edit tab. Copy the image tag from there and paste it onto the other page where you want to use it. This should speed things up! Tom Sponheim 05:40, 20 June 2007 (UTC)

Question about using plastic enclosure as a hot box Edit

Hi Ashok, Can you review the changes I made to the text you recently added to CooKit? I want to make sure that I didn't change the meaning. I would also like to know more about using this enclosure as a "hot box". Is this really possible? Tom Sponheim 23:32, 4 July 2007 (UTC)


Hello Dr

Looks like Dr Abbott from the Smithsonian Institute beat you to inventing the Solar Cooker by almost a hundred years.

Can you add this new Tripod style of hybrid parabolic cooker to the Compendium? Edit

http://www.mealwormfarm.com/hqsolar/hqsolargrillonline.html http://www.mealwormfarm.com/sitebuilder/images/solargrilldiagram-478x383.jpg

This grill utilizes a recycled parabolic antenna. It's very easy to build, stable in high winds, powerful and fast, and versatile. It can use solar or other heat sources for cooking, using pots and pans. It bakes, fries, and even smokes food quickly with just the sun. Please check it out.


Added evaluation criteria Edit

Today I added a suggested list of evaluation criteria to the main page.

To extend this, it would be helpful for someone to define typical numbers for cooking power and maximum temperature that are optimum for small solar cookers.

Can you add these two cookers to the compendium? Edit

Suncatcher and Tripod Solar Hybrid Grill. Thanks! Tom Sponheim 16:36, 25 September 2007 (UTC)

I built a cylindro-parabolic cooker similar to the Tammock Cooker. I was trying to post it, but the "edit" button did not appear. How should I post my design? I can be contacted at mcmullin.joseph@gmail.com

A new fresnel parabolic solar cooker design Edit

I wonder if your fresnel parabolic cookers page could have a review of my design. Truly, what do you think of it? I have created a 3D model of it and I would like to manufacture it using mirror material laminated on blown paper foam with a minimum amount of resin.

Thank you for all your work on this project!

Hi, Webb. Great work you've done on this cooker. There is a need for such designs to allow people to cook Flatbread. You'll see similar cookers here: Helios Array and Devos Solar Cooker. Your's though seems simpler and your method of focusing the mirrors will be useful for many people. Would you allow one of our volunteers to copy the info from your page onto this Wiki? If this is okay, we'll need to ask you to upload your videos to YouTube to allow us to embed them in the wiki. Probably the only one needed is the third one showing the mirror alignment procedure.
Thanks, Tom Sponheim 23:12, February 23, 2010 (UTC)

Webb Mealy Solar Cooker Edit

Dear Tom--

Yes, you can abstract my information from www.selftest.net/media/solar as long as you include a link to my page and mention that there are videos showing the cooker in action cooking. Here, as you requested, is a link to the how to video as uploaded to youtube: http://www.youtube.com/watch?v=vtPGELHfOh4

Let me know if I can be of any further help.

paraboloid with coincident focus and centre of gravity Edit

If the centre of gravity of a paraboloidal reflector coincides with its focal point, only a small torque is needed to rotate it to follow the sun in the sky, turning around an axis that passes through the focus and centre of gravity. The focus does not move as the reflector rotates, so the collector of sunlight can be fixed. If the reflector is axially symmetrical and made of material of uniform thickness, it turns out that the depth of the reflector, measured along its axis from the vertex to the plane of the rim, must be 1.8478 times its focal length. The radius of the rim is 2.7187 times the focal length. (This number is very close to the value of "e", the base of natural logarithms. This is just a chance coincidence, but it can be a useful mnemonic.) The angular radius of the rim, seen from the focus, is 72.68 degrees.

For more information, see the Focus-Balanced Paraboloidal Reflector page of this wiki.
