Here’s an idea for anyone willing to make their own. Attach the frame that holds the turbine to a pole with bearings, that way it turns to catch the wind from whichever direction it’s coming from.

I’ve got a few films tackling various issues on wind power…
And please do pass the link around

Let’s put some along the eave and have a dual-mode water/wind mill.

they could combine wind turbines with solar pannels on it,would generate alot more power,the idea to accelerate wind speed is pretty nice too,but having both solar pannels and wind energy would mean u could make money,and never have to pay

if u put a guard on the fan birds OR anything will not go through the guard thing.

Remember you need 5 of em….

Huh
Good point
September 8th, 2008 at 8:38 pm
$700!?
couldn’t you build this yourself for about $20

id rather have the bird get killed by the turbine then having it shit all over my house (which they do) spreading the diseases even more

True, but the bigger they are, the bigger the maintenance and budget. With current metalurigical process, these wind turbine cost reletively equilvalent to benching weights. Wait until energy shoot to the roof, the demand would say yes to little turbines.

I think wind power is great, but it’s important to know some basic physics when evaluating inventions. The power in wind is the cube of wind speed, and proportional to the area of the impeller, SO there is little power available at low wind speed, and the type of the wind turbine shown here is very inefficient, probably under 10% while a blade based would give up to 40%, so you would need lots of them to power a typical home.

lmao right! there are many ways of safely diverting birds around anyway. how about we go back to coal furnaces, how would they like a black sky and dead everything? tree huggers are never satisfied…

Does Graeme Attey have a web site? Where can we get recent news about this??
September 8th, 2008 at 8:38 pm
I think the birds will stop flying into it after they notice the pile of carcasses surrounding it lol. amaroq38 you’re so full of shit. Wind power is one of the best power sources out there. There are enough locations free of migration paths to build enough of these things to total get rid of the need to coal, natural gas, and other harmful energy sources. It free energy for christs sake!

you could even use it as a running machine by jumping on top of the barrel, like they do in canada weeee……heyy

What happens when someone throws your cat in there?
September 8th, 2008 at 8:38 pm
Haha, You made me laugh, Birds!, Oh thats a good one.

Yet another horizontal - bird trapping and killing wind turbine to be used in close human habitations. Get smart people. More than 60 transmissible bird diseases (some of which are fatal) are associated with geese, pigeons, starlings and house sparrows.
Does no one ever think about birds getting caught up and slaughtered in these - spraying bird offal and diseases into the air around your kids, backyard, cookouts, etc ??

check out my wind power vids…
September 8th, 2008 at 8:38 pm
I’ll take six.
September 8th, 2008 at 8:38 pm
So when is this coming out?
September 8th, 2008 at 8:38 pm
all well and good until you apply a load. Sure the VAWTs spin well in low wind… but usually won’t produce any noticable energy until winds cook at around 45kph. And turbulance effects of the wind at ground level really sucks the power away from these devices… although I hope they figure out how to get around that, I remain skeptical.
September 8th, 2008 at 8:38 pm
and the winning ticket is……..(it looks like a competition barrel) and i agree, without a load on the shaft it is rather unimpresive.

We made only 7KWhs only in one month, if we talk about whole May 2008. 6KWh from them - was produced during one windy day only.
Other days? 0,01-0,02KWh per day. While seeing rotating turbine it is possible to imagine - oh, it makes job now! No, it simply rotates fast enough. But there is no energy in atmosphere these months to produce power.
Sun is what is working now! 15A x 26 V from our PV 525W set, 10 hours every day.

Unfortunately, it is very confusing video and is far from reality. This turbine is not enough even to power single 20W bulb every day, even if winds blow.
Pity that it was on TV as “solution”.
Do you expect “energy” from rotating kid paper propeller keeped at balcony? It is the same.
