Solar Oven


A hand-me-down from my friends Mark and Georgina, local gurus of sustainability. Mark had a couple extras from a demo day at his place of employment, and said, "I'll give you one if you're really going to use it!" No problem there.

The pic is of my first effort: a hastily prepared rice dish, put out around 4 PM, unsure if the sun would be hot enough in the last hours of this early May day. The rice came out of the sun at 6.30, perfectly cooked. It would have felt like a very pure and simple cooking experience if I hadn't needed to microwave the chicken stock we keep stored in the freezer. The lady of the house was not very impressed with that. If only I had an extra hour of sun, I would have been able to shun the nuclear option.

I have some unexpected disappointments to sort through. This is, essentially, an outdoor cooking method, one that my wife seems happy to leave to The Man. But, strangely, there is no smoke. There are also no special tools, no sizzling, splattering of fat, or poking of charred meat with forks. Really I think my disappointment comes down to a lack of fire. I should say, just to be clear, that my criteria for cooking with fire is that said fire be at ground level, not burning at a distance of one astronomical unit.

I can live with it, because with this smokeless cooking method, entirely devoid of splattering fat as it is, there is also no power being used ... so no draw on the power lines in the house, no burden on the grid, no demand generated on some coal-burning plant somewhere, and so no smoke near or far, which means no impact near or far. This is good.

I'm counting on the fact that I'm banking some carbon equity, and can soon plan a meal that involves solar-baked potatoes and veggies, with a side of grilled meat.

  1. Wow. That's a nice one. We'll have to show you the oven that Jordan and Steve made out of cardboard and aluminum foil. Maybe while you're waiting for your food to cook, you could get a magnifying glass and a piece of dry wood and make something.--Ann

  2. Over an 8 hour day you get 600 watts / square meter at a 40 degree latitude, which is 4.8 KWatt hours / meter ^2. Approximately the same energy as 0.13 gallons of Gasoline over the day, for every square meter of ground. About the same as a camping gas burner!
