Hi, I have been working on a solar parabolic cooker made of cob and it is going really well. I am writing here to tell you of my way of making the parabola. All you need is a couple of pieces of wood, some nails and some string and you can make a parabolic bowl from cob! shows some of my method and I urge people to watch it to see how simple it is! NO MATHEMATICS INVOLVED!!! The design I show is totally mine so feel free to modify it and make it better I have used solar with funnel and parabolic cookers to kill weed seeds and grubs in soil. This works well. I have used it for a season. I add water to the soil to make it moist. 3 reasons, wet heat is meaner to grubs and weed seeds and spreads the heat better through the mass of soil and also the moisture prevents the humus from burning. I have bought digital oven thermometers for the summer or 2008 to determine the temperature needed for the process. I think 70 degrees C is enough. This might also be usefull for autumn use to "solarize" fruit that falls to the ground. Often fruit falls because of insect attack. solarization in any solar cooker might kill grubs and spores and reduce infection for the next year. Gardening is very popular across the world. I believe it is not so mission critical to have perfect cooking with this application so people might accept garden solar quite readily! Brian White

Is this your device?

Very clever tracking mechanism!

Hi. I added a page on Tracking. We can start adding ideas to that page. This latest one is very ingenious! Tom Sponheim 19:01, 12 February 2008 (UTC)
