TERRA: Carbon Negative - Another challenge is to fashion a firebox that generates a spiral vortex flow of air, gas and flames. First, this increases the mixing of air and gas for more thorough combustion with a rapid, hot, smokeless burn. But also, a longer flame path holds more heat in the kiln to boost temperatures and improve thermal efficiency. A circular flame path around the firebox and retort is better than bottom-to-top vertical combustion outflow.
Passive heat: With milk jug storage, spray the milk jugs with flat black paint, and add one tablespoon of Clorox-type bleach per jug (to prevent algae growth in the warm water). Secure the cap back on the jug with a ring of caulk. Place the milk jug on a bookcase type frame not more than two jugs high.
DIY rocket stove 4mm steel. Bottom 100x100x240mm, riser (75x75x600mm), feeder 75x75x300mm.A rocket stove is an efficient cooking stove using small diameter wood fuel which is burned in a simple high-temperature combustion chamber containing a vertical chimney and a secondary air supply, which ensures almost complete combustion prior to the flames reaching the cooking surface.
The geodesic form of the dome allows for the most robust design possible to withstand the heaviest wind or lying snow conditions. Regardless of Sun's orientation, light is transmissed directly at right angles at any time of the day and season of the year. Excellent air flow is maintaned even in warm, still weather conditions. The heat inside is distributed evenly at all points Superior to conventional shaped rooms in sustaining better airflow and a uniform temperature inside.
