[Stoves] Comments about T-LUDs: Types of carbon

[frank]

Kevin,

Will this work?? Does the size of the two cylinders (tube and stove 
pipe) need to be the same and will the temperature deference (cold on 
one side and very hot on the other)  be a problem?  I am thinking if one 
were to use a 1" id glass tube as the cross member the air rushing 
across one side is compared to the air rushing across the other  and can 
be adjusted to be equal regardless the size of the two cylinders and 
heat.  But I wonder if cold dense air has more 'push' than hot less 
dense air? And I think the cross tube will need be short and of a 
certain diameter because air will compress unlike water?

Thanks for your opinion.
Frank

Another idea; Like measuring the speed of water or flow of electricity. You
set up a vertical tube with air flowing through from an outside source. The
air speed is regulated and known via a needle valve and flow meter. You have a
connector pipe between the center of the tube and the center of the stack. In
the center of the connector you have some direction indicator. Could be made
of clear glass and a piece of yarn stuck at the top inside. You adjust the
flow meter until the yarn is not moving in either direction and the flow of
the tube is the same as the flow in the stack - I think??
