...you feed him for a day. Teach him how to fish...

...and you'll piss his wife off for the rest of her life.

I'm going to be doing a lot in the coming year as we travel the country, but my wife won't mind as we'll mostly be doing it together. The plan is to go boondocking and live on very little money and so catching our own fish goes a long way toward helping with that. We just built a solar oven out of a tire and satellite dish with excellent results. We've cooked several meals in it, spaghetti, roast beef and carrots and today we hardboiled a dozen eggs for egg salad. The spaghetti took only 30 minutes, the beef pot 6 hours, and the eggs were in for around 2 hours. We are so pleased with the results that we built another larger one with better reflectors to take with us at the end of the month. Can't wait to test that one tomorrow.

8), I Have a satellite dish lying around, can U post a photo of what the oven looks like, I would be interested in making one too. :), Did you have to apply anything to the surface of the dish. :?:

I would imagine that the building process would be tyre at the bottom. The dish would then sit on tyre (to keep the dish away from the cool earth, and the tyre would be a nice dish holder as well), and line the dish with some reflective substance - aluminum foil or silver tape perhaps for the reflectors.

Then it's just a case of having a "food holder" that is above the dish in a certain location (the hot spot), a grill hanging down to hold food or pans, or a metal/glass/perspex box for the oven - the worlds your oyster.

That's what I would imagine from his description anyway.

You could probably purchase emergency survival blankets for 2 or 3 dollars (basically plastic sheet with a mirrored finish on one side) at any sporting goods dealer.

Hell Nettie, if you're leaving for a year, they'll come in handy for those brutal prairie winters, which start in 2 months! :P

Here is a picture of our design. I cut one sidewall out of a light truck tire and half of the other sidewall as well. I then cut a piece of plywood in a circle a little larger than the smaller hole and screwed it to the tire from the inside. I cut 12 wedges of 1/8" hardboard 6" wide at the top and 2 3/4" wide at the bottom, 11" long. These wedges were wrapped tightly in aluminum foil, placed inside the tire and taped together with reflective foil tape. The top of the reflector is secured to the tire with duct tape and the bottom with reflective tape. The secondary reflector is a satellite dish lined with foil tape.

I would have liked to use an old 10 foot dish for a reflector but that wouldn't travel well in the back of a pickup truck. We needed something a bit more portable.

Thanks, you're too kind. Today was a disappointment because the weather forecast suddenly changed early in the morning from all sun to mostly cloudy with a chance of rain and we have to put off the test of our new design until tomorrow. Really, I don't understand why they bother publishing a seven-day forecast when they can't even get tomorrow right :?

Bloody good stuff NM, very neat, you are some engineer. :)
What gauge of foil did you use, the ordinary stuff from the supermarket, or something a bit more industrial. :?:

It's from the supermarket but it's called 'barbecue strength' foil and it's much wider than a typical roll of foil and about 3 times as thick. My heart's desire is to get a large mirror and cut wedges out of it to glue to the wooden wedges but I'm such a hamfisted donkey when it comes to cutting glass that there's little point in trying. I just end up with broken shards of glass everywhere.

Thanks for the info NM, I know what you mean about cutting glass, there is an art to it, I get jagged edges when I try, you could get the mirror cut for you by a glazier, they would do it quick, and it probably wouldn't cost much.
