New Wind Turbine Design Good for Rural, Urban Environment
VOAvideo asked:
Wind power is one of the fastest growing forms of alternative energy in the world. More and more, wind power mills are seen in the countryside, in large wind farms and for the most part, away from city life. But a new form of wind power is now designed to work in an urban environment. VOA producer Zulima Palacio has the story. Mill Arcega narrates. …

I dont care what anyone says, in URBAN surroundings, vertical axis wind turbines seem to be the best way to go.

Lots of hype without many facts. Fortunately for folks who are interested, NREL (national renewable energy laboratories) actually did test this system, on a good site, without trees or buildings to obstruct the wind. The system produced 108kWh over the course of 8 months (average 13.5kWh/month or about 1.6% of the energy consumed by the average home! A far cry from their claims of 25-30%). Google ‘nrel mariah’ to read the facts. Hold onto your wallets!

how do i download this video

I think if any windmill appears to be nearing max speed, “shifting” to lower gears may help this and perhaps sustain some of the efficiency at high speed.
I think we should also look at ways of harnessing more energy from the current turbine speeds we can do. Things like automatic gear decrease/increase.
Cool.

The US uses 3.3 terriwatts of power. How many terriwatts of power could I buy for $819 billlion?
Mutske161 on Sat, 21st Mar 2009 8:34 pm
I know a way to make it produce even more power at the same windspeed and hight.
I think with 25% more Watt.

These were kicking ass in Washington this weekend when I was there. The vertical turbine looked as if it was turning 3x faster than the prop one.

that’s an interesting boating idea, thanks for mentioning it.

Darreius turbines have much narrower power curves than rotaries, making them crappy for high variance environments like cities. Not sure what beyond the aesthetic they are going for with this…

It’s a Darreius design. That was invented a long, long time ago. Most Darreius turbines are the “eggbeater” style, but this is the same principle.

nice, but without variable blade pitch the vertical axis windmill loses too much on the back end

its said that colleges might use them by 2013

the name of the company is: “mariahpower”

If I am not mistaken, Helix Wind people were the first to build those kind of wind generators.

You can find the link to the company via Google. Search for windspire. I’d post the URL here, but Youtube is being retarded and won’t post a comment with anything even *resembling* a URL.

Hey, this is a cool video…
I was bored out of my mind one day and had this idea for this website where anyone can post about anything they want when they are bored. It is really funny to read all the random things people say.
Here is the web address(sorry, Youtube will not let me put a link in here):
boredoutofmyfreakingmind(.)com
Please visit the site. I am trying to get some more posts to give the site a proper kick off. Thanks for your support!!

they used to use these in a prototype boat that would release no emissions but rather move from the high amounts of wind over the water propelling them, used in discovery show Green Earth i believe is the name

The first windmill was vertical axis, and was used by the Persians thousands of years ago.
ObamaTaliban on Tue, 14th Apr 2009 6:05 pm
That wind turbine would look better if the man talking would show us a different angle of his belly….j/k….nice job!!!

Free Energy, the government can’t make money off of that. Wind/Solar/Geothermal are the future energy sources!
bitplayer2 on Fri, 17th Apr 2009 8:49 pm
why isn’t there a link for the company? I’d love to check out their products.
