Wind Driven Electrical Systems

Hi guest,

I have my own project in wind-driven generators for built environment and I did a lot of research in what others published so far. What I can tell for sure is that any accessory having exposed moving parts attached to a high building is considered hazardous. No one would like to see a fin or any other part falling on a crowded street bellow or rushing through a window.

Safety is paramount in any such design. Your idea may have a lot of merit from the Physics point of view, but in real life, you should be fully prepared to give answers to those who could give you a permit.

Technically, what worries me in any VAT (vertical axis turbine) is the long shaft. Vibration is critical and bearings have a short life.

My comments are not aimed to discourage you. My suggestion is just to stay close to architects and structure engineers and to do more research.

The vertical updraft has a lot of energy and is worth trying to harness it!

Good luck in your quest.

Check the TMA wind turbine site - they are just getting ready to come on the market, and they have done an excellent job in the wind tunnels proving their technology. Part of their business plan is the built environment. As with any wind plant tied to a structure, you have to be careful of vibration/harmonics being transferred into the building itself. good luck!
