Everything related to heat transfer is still relevant and very, very interesting, but I love how dated the assumption of non renewable energy is now in that method of calculating thermal efficiency.
Who cares if the perfect turbine could only ever convert 59% of the wind power through it!
"a rocket mass heater consists of an insulated combustion chamber where fuel is burned with high efficiency at high temperature, and a large thermal mass in contact with the exhaust gases which absorbs most of the generated heat before the gases are released to the atmosphere.... "
