Me and my hang gliding buddies have been talking about something like
this for a while. We are interested in using the convective force not
to drive air through filters but rather to trigger larger convective
currents in the air. Yes I am talking about a thermal generator. It
would be so nice to have a house thermal always reliable and present
on the location of our airfield. Jason do you have any data on the
device? What kind of air flow rate does it produce? Is there an
optimal shape, are there advantages to building it next to special areas
like a woodlot or a pond from which it can draw cool air, or is it
better to have it in say an open feild where it can draw air which is
already somewhat heated by the surrounding soil? What about materials
choices for cost vs. performance tradeoffs?
