Re: Solar oven?

Living in Tucson AZ there is plenty of solar energy to play with. Not sure that this is very applicable to a marine environment, but I have constructed a solar oven using two cardboard boxes, one nested inside the other with newspaper stuffed between the boxes for insulation. The inner box is lined with aluminum foil and a plexiglass sheet is laid on top to help trap the heat. Cooking is done with a dark colored pot to help absorb the heat. I regularly use this to cook my chili during the summer, then freeze it for use later when I go camping or sailing. I usually see temperatures of 150-160, but it still takes several hours to cook a pot of chili.

Perhaps this will give you some ideas of what can be done without spending much money.

Re: Solar oven?

You can get a fairly cheap knock off of the gosun from china on ebay...just a thought... i really really like the design of them. But i do not like the price tag either! I believe the knock off is around a hundred or so american. Looks the same? 🤔

Re: Solar oven?

Here's a vacuum tube that's four inches diameter which I think would be much more useful. And it's less than $50.http://m.ebay.com/itm/192029906924. I ordered a solavore ( full size solar oven) that was on sale for about half price. I can't wait to try it out.

Re: Solar oven?

Glad to help Sea Dreaming. Here's a YouTube video that shows a collapsible solar oven. It's in the middle of the video so you might want to skip some. I don't think it's the best option for an oven but I thought it was something people might be interested in.

You can also make one yourself from one of those sun shades that are made for windshields of cars just look up funnel oven.

Re: Solar oven?

Once one has acclimatized to the heat of the area one is in, my experience has been that stove top baking and cooking is okay. It helps if there is an opening port over the stove, and a galley hatch a couple of feet forward of it, or a fan you can direct on the person who is cooking, but using the pressure cooker without the gasket works fine for baking breads of many different densities (you might want to put an aluminum foil "tent" over it to reflect heat back to it.)

Girl Scouts used to make reflector ovens from old cardboard boxes and new heavy duty aluminum foil.......

Re: Solar oven?

Solar Cookers International sells many cookers, water pasteurization indicators, books, accessories, etc. They exist primarily to aid refugees and people in remote or third world places where the women walk miles to get firewood, causing deforestation/desertification, getting raped and robbed on the way, health problems, etc. There's one cooker that folds up very small. GOOD PEOPLE!

Is our recommendation. It's made in Cincinnati, where we sail. I have not bought one yet since the wife has the purse strings, but I know the owner and it's the bomb.

Re: Solar oven?

When I went through Oriental NC it was during a cold snap, down in the 20's/30's, and windy. There was a guy at the dock using a solar oven on his coachroof. I was dubious and asked him about it and he showed me that the temps inside were around 300 degrees. I was subsequently impressed. I don't recall the brand but it was one of the box types with fold out reflectors.

No kidding. Effective cookers like these will keep a pot >160 for up to 8 hours. Boil dinner and leave. I love it for rice. And no heat in the galley. Makes solar seems a little silly.

An electric slow cooker makes no sense on a boat for most foods, even if you have the power. Retained heat is faster (less warm-up time). It is only better for a big roast. Yes, I've used both.

Re: Solar oven?

For those interested in using the vacuum tube type oven here's how to make a parabolic mirror for it. But you could use PVC "boards"for the frame and polished aluminum for the reflector.https://youtu.be/TfT3JHlByhI

Re: Solar oven?

Like I said before I think the 4-inch vacuum tube for $50 is the way to go but if you want a gosun here's one for about half price. http://m.ebay.com/itm/STOVE-SOLAR-CO...%257Ciid%253A3

Re: Solar oven?

Here's an example of cooking cookies on a homemade funnel reflector made with a utility truck windshield shade.
https://youtu.be/MVrniLvve48
Unfortunately in the video how to make it she just discusses the glass container and the stoneware container but doesn't show how to make the funnel.
