Koine Multimedia proposes Hammurabi:

a wind confined vertical axis turbin.

Since 1700 a.c. Persian-Mesopotamian cultures has been using vertical axis windmills integrated into masonry structures.

The system proposed  shows an invitation to the prevailing wind direction and a vertical axis turbine which has relatively high efficiency as it works with a flow ducted air.






This very structure, with modern technology, can be used on the flat roofs of ordinary buildings of at least three floors.



On these roofs it’s possible to place cylindrical structures 3-4 meters high and with a diameter of 4-6 meters  .

They have a conversion efficiency of about 50%  and can be managed in multiple units on the roof of an apartment building.

The typical power varies between 3 and 8 KW..
