Now that we have running water in our bathrooms, I'm going to say there's zero market for a large tin bucket with no tap that you're supposed to fill using water you've boiled after collecting it from a nearby well. The modern way of taking a bath is just so much better. But there are companies pushing old-school ways of cooking.
And by old-school, I'm talking Stone Age technology. UK-based The Stone Bake Oven Company is hawking a line of indoor/outdoor wood-fired ovens that you load up with actual chopped wood. The ovens themselves take the shape of igloos, as the designers have apparently learned what the Inuits know, which is how to keep heat dispersed evenly.
Capable of cooking a vast range of food types (from roasts, to casseroles, desserts to fish dishes, breads, pastries fruits and more), by burning only wood, Stone Bake Ovens combine age old authentic Italian cooking techniques with thermal technology and design, to ensure your oven's authentic cooking style, efficiency and longevity.
While these ovens have existed commercially for pizzerias and the like, the SBOC is aiming to make them domestically affordable (a relative term) with prices starting around US $1,000.
