[Stoves] Find truth about Re: Turbo-Cocina, turbo-cooker Wins Prize for Clean Burning

[Nikolaus Foidl]

Dear Andrew!

The claims to save 98 % of energy is widely overstated, from viewing the
stove work I estimated in a short calculation taking in account the quantity
of woodchips and the quantity of water heated, an efficiency in the range of
30 to 35 % and that's average for me comparing it to other gasifier stoves I
have build myself and as well I have seen working. As usual some reporter
who has not a clue why somebody got a price hurries to invent a nice
interesting story to sell an article. That's it. That Salvador coming out of
a terrible civil war with lot of death and hatred desperately needed heroes
to get hope again even was misunderstood by the " inventor" himself.( he
still beliefs that he is an inventor and genius) Same happened with lady
Menchu in Guatemala. If you look at the drawings in his patent you
immediately see the limitations, for being a good gasifier, you can not load
fines like sawdust because the horizontal flow would be stopped , you can
not load more then a few centimeters of gasify able material otherwise you
block as well the up words directed air, diameter of the gasifyer is as well
limited otherwise the air causes burning only the outside and the center of
the accumulated wood waste.( chips and sawdust etc.) Wood needs to be bone
dry otherwise wet smoke and air mixture leads not to a burnable mixture. No
defined flame zone and gasification zone, as long the air is blowing out the
flames you have pyrolisis, if the velocity of the air stream towards the
wood chips is too low then you have simple burning.( too much oxygen at the
surface of the woodchips).
Best regards Nikolaus
