We’ve previously reported on Barbara Kerr’s solar wall ovens for home use. They’ve been a favorite of mine for over a decade. Yesterday I just came across a larger version of this concept – a commercial size solar wall oven by Gregor Schaper over at Inhabitat.com. The cookers can reach temperatures up to 1,020C and save 16 gallons/month of fuel. His company Trinysol sells the cookers for $4,000 to $5,000. These ovens would work well for restaurants, school cafeterias, eco-resorts and other similar commercial applications.
