Post by thread:[TECH]:: Solar Cookers

There are a zillion solar cooker designs in the world, ranging from extremely cheap and so\imple to very high tech. Here's some: Some (but not most) would operate to some degree on an overcast rainy day. I have observed (and burnt my hand on) steam coming out of an evacuated tube solar heater system under such conditions and at least one design here uses these. Plans for 31 simple solar cookers http://solarcooking.org/plans/ More. Some VERY real - see eg Helios Bread Oven !!!!!!! http://solarcooking.wikia.com/wiki/Category:Solar_cooker_plans Index page by over type with links to other pages 37 designs listed here http://solarcooking.wikia.com/wiki/Compendium_of_solar_cooker_designs 130 designs Vast range - from trivially simple to rather high tech, http://solarcooking.wikia.com/wiki/Category:Solar_cooker_designs Novel. Cooksack. 7" foldup and 12 ounces (200mm 340g) Oven proper is 34g. Read between the lines suggests it has issues which are being looked at. http://www.terra.org/cocinas/fichaen.php?id=88 What works - report http://solarcooking.org/research/Dormio-report.htm Winebox cooker - transitioning to square foot paste up mirror cooker. Credibly high performance claimed http://solarcooking.wikia.com/wiki/Winebox_Solar_Rice_Cooker Winebox version construction details and discussion Jar in jar adds substantially to performance (probably) http://transitionreno.ning.com/group/simplesolarcooking/forum/topics/the-cheapo-winebox-cooker 80 designs from various sources http://www.terra.org/cocinas/searchen.php?tsearch=&fam=&prod=&pag=1 Fresnel Some good prospects http://solarcooking.wikia.com/wiki/Fresnel_solar_reflectors I like the DATS cooker - 2nd item down http://diyenergy.blogspot.com/2007_08_01_archive.html __________________ Needless to say, if you can cook food you can pasteurise and even sterilise water as well.

I thought of noting with my prior post that Iceland is the largest grower of bananas in the EU ! :-). Thermal springs work wonders R

There was (1980) only a couple of banana palms and some trees. They are grown in greenhouse and the thermal springs play a part in maintaining the temperature. The greenhouse (also a tourist attraction) is not a greenhouse in the back garden glass framed affair, the walls are actually made of brick and wood. The ceiling (from what I can remember ) does have some glass, mainly to let light in.
