This simple, inexpensive furnace will make other future projects possible, and was a good simple project to start off with. Unlike the one shown in the video, it has a longer board to support the tank as one whole unit, the flame nozzle will be safely locked into the can (so it won't be able to slide out accidentally), it is slightly larger, and the control valve will have easy access.
The insulation on the inside of Steve's furnace was roughly 49% sand, 49% plaster of Paris, and 2% smashed ceramic. An improved mixture with more ceramic will be used in a second soup can furnace if a better method for smashing up ceramic into a fine powder can be found.
Due to outdoor work in the summer heat of Florida with an unforgiving work dress code, the need for some personal cooling arose. Having recently taken an interest in electronics, I skipped the search for a product to buy and instead started on building one. The casing was made out of fiberglass (mat, resin) placed in a food container with a rounded square base. The fan is a 12V blower that can put out about 24 CFM, and the power source is a battery pack which holds 8 AA batteries, which are 1.5 volts each. The fan and battery pack were bought on Jameco's web site, while the fiberglass materials, switch, and wire connectors were bought at Advance Auto Parts.
The biggest project Steve will be taking on for the foreseeable future, the "power armor" is influenced heavily by the latest Marvel movies of Iron Man and power armor found in the Fallout series.
The design will likely take cues from the one constructed in the television show James May's Man Lab. A more robust plumbing design will be used, keeping the air intake at an angle so that a vortex effect can be achieved inside the furnace (potentially leading to higher temperatures and a more even burn of the fuel).
