Though wood appears to be an abundant resource at the present, with declining sources of natural gas, oil and coal, the only other option is nuclear, wind, solar and wood.

Wood for heat is expected to grow nearly 600% in the decades and at one time - Europe had been stripped clear of all major forests because of a mini-ice age and the use of wood increased as a result. The only way to accomplish this responsibly is to access the kinetic energy (meaning you assess near 100% of the atomic energy stored in the materials). IF you could access the kinetic energy in a rock - you could heat a city for a day.

Though we haven't figured out how to get the kinetic energy out of a rock yet, we can do it with wood. Several wood burning technologies were used before all the other sources we use for energy came on the scene. In the mid-1800s, the Bessemer burn technique was developed - it creates a cyclonic fire which burns off gasses and leaves biochar to use in the soil. The mason fireplace heats in a flat Taurus burn in much the same way but heats a massive stone. The placement of the stone is critical as it expands and contracts from the chanes in temperature. More recently, the technologies were combined to both cyclonically and Taurus burning in metal chambers and can heat mass for long heating periods from wood. This system is near kinetic energy use since it burns off 90% of the gases and ash. What remains is some ash and only a faint odor of smoke.

To get the process going is the hardest part but in the end your goal is to have a "chimney fire" controlled in your firebox. Temperatures can reach a plasma burn state and are used to heat water, transfer fluids and mass so the heat collection process is as important as the initial heat itself.

Experimental model designs can quickly get out of hand so do any of your own research with caution. We make units for both add-ons to existing fire boxes as well as total burn units.
