The real world offers better lessons than any book or armchair discussion.
as “an increase in the average temperature of the Earth’s atmosphere,” either by “human industry and agriculture” or by natural causes like the Earth has “experienced numerous” times “through its history.” * Some writers use the phrases “global warming” and “climate change” to mean temperature changes strictly caused by human activity.   Other writers use adjectives such as “man-made” and “anthropogenic” to distinguish between human and non-human causes.  (“Anthropogenic” means “of human origin,” and “AGW” stands for “anthropogenic global warming.”) * Just Facts’ Standards of Credibility require the use of “language that is precise and unambiguous.” Hence, when human causes are stated or implied, this research uses terms like “man-made” and “human-induced.” * The greenhouse effect is a warming effect caused by certain gases that retain heat from sunlight. Without such gases, the average surface temperature of the Earth would be below freezing, and as explained by the , “life, as we know it, would not exist.” The global warming debate is centered upon whether added greenhouse gases released by human activity will overheat the Earth and cause harmful effects. * Human activities currently release about 37 billion metric tons of CO2 per year, which equates to about 5% of natural CO2 emissions.
A super-hot chimney above the fire draws the flames sideways and up, blending hot fuel and air into a quick, hot, clean-burning fire that takes little wood, leaves little residue, and has lots of uses.
Variations on the same concepts include Fox-stoves or Badger-stoves, cooking Rocket Stoves, Dakota firepits, traditional furnaces, kilns, modern incinerators, smokestacks, bell-stoves, and millions of humble tea-stoves and household hearths developed by resourceful people all around the world.
The Rocket Mass Heater takes this useful, clean-burning heat, adds a self-feeding wood box, and channels the exhaust through a masonry block to store touchable warmth for hours or days.
(Masonry heat storage is also seen in Roman hypocausts, Chinese 'kang' stoves, European masonry heaters, and ancient masonry dwellings and hearths).
A few older reports are here: Rocketeer Reports(Other video is available too - like this interesting all-masonry bell stove variation:

He could use some help if you're interested. Paul Wheaton's podcasts and You Tube videos are a great way to hear ongoing discussion. Rocket stoves are a type of fuel-efficient device, named in the 70's, but dating back millenia in concept.
By comparing data from poorly positioned stations with other stations that are properly positioned, the study determined that the temperature irregularities in the poorly positioned stations cancel one another so that their average temperature trends are “statistically indistinguishable” from the properly positioned stations.
As of July 2015, no similar study has been conducted on a global basis. * From 1979–2014, the three temperate datasets posted above differed from one another by an annual average of 0.13ºF (0.07ºC).
We recommend practicing with the basic design in an outdoor setting or workshop before attempting any changes.
