Wind-Pressed Walnut Oil
Food should be made the right way, with good ingredients. A simple oil press can be made; using only wind powered energy. The wind power is transformed into a worm drive that provides slow, but powerful movements. The machine is intended for nuts and seeds, and using no heat in the process produces fresh, pure cold-pressed oil and a nutritious pulp that is great for cooking, or using as animal feed.
