Parabolic solar ovens exist, but they are meant to be used while the sun is shining. I would like a solar oven that is really well insulated with a glass door. A parabolic dish directs a big chunk of light into the oven, and the resulting heat is stored in the fire bricks. When you get home, the pizza oven is ready to go.-- nomocrow, Feb 25 2009 (?)

But as it might also be a communal oven, and raises awareness for solar power [+]-- loonquawl, Feb 25 2009 Is a private pizza oven wasteful? I was actually hoping to save energy here.-- nomocrow, Feb 25 2009 I think you could use the garden solar water heater concept on this one. I can't find the pic of one I saw a long time ago anymore, but basically it was a series of copper pipes wound around like a radiator on a piece of sheet metal - all painted black. At the top of this piping was an insulated cooler with a single pipe returning to the bottom of the radiator.
I think you could do a similar system for an oven.-- Zimmy, Feb 25 2009 Zimmy, To get enough heat to cook a pizza, you can't use the direct light of the sun on a surface... it just wouldn't be hot enough.
You'll need to use a lens or mirrors.
nomocrow, you've left off an important component: it needs a thermometer, so you know if your pizza oven is too hot, or not hot enough.
Oh, and you don't necessarily need a parabolic dish... you could also use a big fresnel lens.-- goldbb, Feb 26 2009 I used sun to make crackers in my campervan. First you take some sliced bread and cut them into a small bite size bits. Next you need a long and sunny hot day and your vehicle parked in the sun, dashboard facing to the sun. Place the the bread bits into a black metal tray in the dashbord facing the sun. Wait for 4 to 5 hours and those crackers are crispy and ready to eat.-- Pellepeloton, Feb 26 2009 You can cook anything with a big enough mirror and an insulated box. And the link here comes the sun shows one made of recycled materials.-- travbm, Nov 05 2015 random, halfbakery
