On May 4th, the traditional ovens are based on the burning of carbon or gaseous fuel to make the food oven. The process is not clean and not environmentally friendly. If you have tolerated the traditional oven for a long time, you can pay attention to the above picture. The all-solar oven called GoSun is on the crowdfunding site Kickstarter.
GoSun can use two curved reflective metal plates to concentrate the sunlight from different angles and reflect it on the sealed baking drum as the core part. The pull-out grill is enough to hold eight people's food.
In addition, add a little more money to get a built-in "thermal battery" that can store enough heat for cooking at night after two hours of sun exposure. It should be noted that this so-called battery is not a chemical battery used in our electronic products. In fact, it is just an organic wax stored in an aluminum casing. If you want one, the minimum investment amount is 349 US dollars (about 2170 yuan).
