so.. why does the hot air rise up through the chimney and not escape through were it came in as cooler air before? wouldn't it be more efective if the height of the greenhouse would increase more drastic as it gets near the tower?
This is spectacular; I think a slightly more dome shape design of the glass plate placement might create a faster updraft toward the tower, as well as capture and lead normal wind currents toward the tower (like an umbrella). Also, could there not be several turbines added to each tower?
I love the observation deck and agricultural usage of space below; use those both to help fund the facilities maintenance!
Quick question to anyone who actually knows what is going on here: Why is the turbine placed at the bottom of the chimney? Would the air speed be higher toward the top of the tower, thus rotating the turbine faster?
@dmirti1993 good question.the mass flow rate, m (lb/sec) of air enters and leaves the chimney at the same rate. using this and density of air at top and bottom (p), the volumetric flow rate, V (cubic feet/sec) can be found. m= (V in)*(p in)=(V out)*(p out). the velocity (v) ft/s can be found by taking V and dividing by the cross sectional area, A (square ft).so given (p in) and (p out) as well as either V in or V out, the other V can be calculated and then each divided by the area to get v.
@dmirti1993 so whichever side of the chimney top or bottom has the lower density will have the higher volumetric flow rate, and assuming constant area of the chimney, then will have the higher velocity.

Can't wait for the day when my home is fully powered by one of these things.

Despite needing serious refinement, this idea is so...odd...that it's fascinating and almost addictive.
