i just had this idea, and the more i think about it, the more i wonder why i have not seen it before.

an electrical baking oven of good quality has some properties that make it interesting:

- good thermal insulation
- lighting (since you rig it to run at low temps, you could replace the heat resistant light bulb with more efficient LED lighting)
- a ventilator for even distribution of heat
- a window
- heating coils at the bottom and at the top (would need to be rigged and get an overhaul)
- built to resist humidity (even hot steam)
- if you un-rig it again and make sure its empty, self cleaning and sterilizing function.


basically all that would need to be done is to reduce the wattage of the heat coils and to maybe add the right resistors to bring them into the operating range of a thermostat. maybe build in fuses that cut at a certain wattage and prevent the coils from ever reaching their maximum power output. and a good proportional thermostat that can run these coils at the desired temperature.


am i missing an obvious problem, or could this work? what do you think? basically all you need is a good thermostat, and some cheaply obtainable electronic parts (resistors, fuses, a bit of cable). and you need to know how to weld and how to insulate cables.
