Do you have any information available from your testing of VAWT or know where I could get same? Thanks Bill Reinhart I’m doing research into the potential of urban wind power.

I am currently looking at technology by Mass Megawatts Wind Power (ticker MMGW traded in the OTC market in the U.S., website is: www.massmegawatts.com). It seems to have a modular, scalable VAWT technology that can produce electricity with a turbine size as low as 25kW - or much higher if you desire. The design uses a rectangular lattice structure for stability (eliminating the need for guy wires) and the parts are all mass produced and in most cases commoditized so as to greatly reduce costs. The power efficiency is only 28% but the reduced costs and easy maintenance (the gears, bearings, etc. are all at ground level and easily accessible) make the investment apparently very economically viable - especially if you use it in conjunction with an augmentor. I am in the process of testing a location now. Should have some results in a few months. I believe this company was short-listed for the Freedom Tower as well, but it was eventually concluded that it would be too expensive to construct since getting the required materials to the top would be incredibly difficult. Full disclosure: 1) Separate from the feasibility of my own wind power project, I concluded that I liked MMGW enough that I now own the stock. 2) I am a Canadian ex-pat living in New York City now.

Very helpful. I have heard of the McKenzie Bay business, and at one point I believe they were shortlisted to provide VAWTs atop the buildings that eventually replace the World Trade Center in New York City. Not sure where that led. Thanks for these comments above. Very helpful.

It is marketed to out of reach settlements of Northern Canada or Russia, and urban settings, such as Chicago or New York City. The VAWT is equiped with a vanadium battery mined in Chibougamau, Qc.

Indeed, it "fits" better on rooftops than horizontal axis turbines because of the height and space requirements. But they are also very expensive for the small amount of power they generally provide. A 2.5 KW tower produces enough electricity to offset about $1,800 annually at $0.08 per kw (in the Northwest where I'm located, the price of energy is about $0.06). When we considered the total cost of the equipment, installation, and maintenance, it takes at least 20 years for pay back. Unfortunately, we still base our value on the dollar investment instead of the great need to utilize technologies like this. Until we truly see how valuable capturing wind energy is in designing and constructing new buildings, this reality won't be seen. <a href="http://www.turby.nl/" rel="nofollow">Turby</a> <a href="http://www.google.com/search?q=the+turby&sourceid=mozilla-search&start=0&start=0&ie=utf-8&oe=utf-8&client=firefox-a&rls=org.mozilla:en-US:official" rel="nofollow">Google Search</a> I received a presentation on VAWT and learned a great deal about the technology.

Not being an engineer, as far as I understand there were certain defects that made the design impractical in the scale of that project. I also believe that maintenence was not very practical. Can't recall all the details, but the information is out there.
