"To help feed the country’s population, an inventor, Toufic Hamdan, created a commercial bakery to bake bread in solar ovens. The startup “Partners With Sun” has installed a solar convection oven on the bakery’s roof. The Solar Oven uses large silver mirrors to capture and magnify the sun’s rays to build heat. The heat is transported by a transfer fluid which is then used to help operate a convection oven, allowing it to reach a baking temperature of between 300 and 400 Celsius. The heat is used directly in food and beverage production. " Baking Bread in a Solar Oven | Happy Eco News

According to the company website, “The Solar Oven cuts up to 80% of the bakery’s fuel bill.”

    This is a really interesting idea, however, it would be good to see how efficient it is. I would think going from light>mirrors>liquid>oven>bread is less efficient than going from light>solar panel>oven>bread.

    Either way, this is a creative design, and could be used for other applications. Could a house be heated in the same way?
