Proof of Heat. Yesterday the latest test with the blast furnace was concluded. 1 hour at 850 degrees Celsius. The backup device is still perfectly intact, readable and usable. Because stainless steel is not magnetic a steel screw is there for a dual purpose. Both to be able to use a magnet if you need to get it out of a difficult location and to hold the turning discs locked. The screws came out hot but magnetic and still operable. It’s all about proof of work in the end. The seedsafe is in our opinion the most battle tested and thought through backup in existence currently.
