Broadstar Windsystem's AeroCam wind turbines break elusive price barrier
As wind energy becomes a practical necessity, designers are scrambling to make the giant spinny things as visually inoffensive as possible. Some are small, some are off in the sea where we can't be bothered, and some just look really pretty. In this case, Broadstar AeroCam developed this handsome horizontal-axis turbine that can be installed in any number of configurations and shipped easier than other turbines, making it a viable solution for those who don't want to erect a giant pole or get involved in construction. AeroCams work on the physics of air lift -- like wings on a plane -- resulting in a huge amount of power from a small package given the amount of blades per unit. Broadstar also brags that the system's price is a boon as well -- a 250kW system runs $250,000, which it says makes AeroCam the first wind power system to break the $1/watt cost barrier.

What's wrong with erecting a giant pole? I do it all the time.

Enough talk of your boyfriend...
Catsceo @ Jun 19th 2008 5:55PM
I want one!

i really don't see why we're not building nuclear power plants...
threefingeredlord @ Jun 19th 2008 5:55PM
I actually prefer the look of the regular big white turbines (never though they looked ugly), this thing looks like it was assembled out of bit's of an old helicopter IMO.

Birdie chop chops?
Fancylad @ Jun 19th 2008 6:10PM
Actually they say that unlike a traditional turbine, when this one spins it appears as a solid cylinder and birds will fly around it. The traditional turbine is what you need if you want to make blackbird pie.
Sean O @ Jun 20th 2008 3:24AM
I love how whenever wind power comes up, everyone's suddenly so concerned about birds. Incredible amounts of birds are killed every day by trucks, glass windows, and power lines. Wind turbines don't kill birds in any meaningful way. It's like comparing the number of cancer deaths to the number of shark attack deaths.
Ken @ Jun 20th 2008 9:31AM
You'll be concerned when you start picking up pieces of pigeon off of your lawn.
You forgot to read the "can be installed in any number of configurations" part.
Ken @ Jun 20th 2008 9:33AM
forget the installation quote part, that was in reply to someone else, but the post seems to have vanished.
ENGADGET fix your damned comment system!!!
andy @ Jun 19th 2008 6:00PM
So how much power do I need for my house?
What about smaller units?
I live in IL where we're seeing 50% year on year energy price increases, and I'm about ready to do something about it.
Bunson @ Jun 19th 2008 7:45PM
Is your energy bill more than 250,000?
rock99rock @ Jun 19th 2008 6:08PM
Forget those solar panels from earlier today. i want THIS on top of my car!
RikF @ Jun 19th 2008 6:24PM
pleasepleaseplease be joking...
jollyllama @ Jun 19th 2008 6:26PM
Um, there's a problem with that idea... I'll give you a hint: It ends with "rag".
TheGasMan @ Jun 19th 2008 6:50PM
I think he means he wants his car to be propelled by this, not to drive his car to generate electricity.
Tomheivers @ Jun 19th 2008 6:58PM
You'd still have drag.
Cuz it's on top of the car and all.
kal326 @ Jun 19th 2008 6:11PM
Printed solar cells hitting a $1/watt and now wind turbines hitting $1/watt, decisions, decisions.....
jdog @ Jun 20th 2008 1:17PM
that's easy - get both. Hybrid systems are common....figure when the sun's out there may be little wind...but when there's plenty of wind there might be less sun (ymmv depending on where you live). I had started doing specs on a hybrid system like this for a remote cabin.....I think it's the way to go.
MBS @ Jun 20th 2008 12:44PM
Solar-cell-covered-wind-turbines DUH!
hondosan @ Jun 19th 2008 6:22PM
it doesnt really lool like it would turn with the wind... that's kind of odd
LarryLarryLarry @ Jun 19th 2008 6:25PM
How can they know I will get 250kW power output from their turbine? Do they control the wind in my town?
Bunson @ Jun 19th 2008 7:48PM
Larry... Larry... Larry *shakes head hopelessly* THEY control everything. EVERYTHING!
Bunson @ Jun 19th 2008 7:48PM
FUCK, my reply to larry vanished.
John @ Jun 19th 2008 6:28PM
An average house (in Europe) used 3875 kW of electricity a year and pays around $1080 a year for it. So it would take 231 years to get a return on investment!!!!
I would buy one if the it took 15 years for it pay for it self. So once the price goes down from $250.000 to $16.000!
Surur @ Jun 19th 2008 6:50PM
Actually the device provides enough power to run 23 houses at your stated average yearly rate completely off the grid (if the wind always blew at peak capacity of course :) ), so it would cost a little more than $10 000 per household to get of the grid,
That means it should pay for itself in around 3 years, which is pretty cool. Sounds like a good community project.
Jasper @ Jun 19th 2008 6:57PM
I think you have your units wrong. The 3875 is probably referring to kW*hours. That how the power that you pay for is measured.
If you do the math for how many hours there are in a year, then that would mean that the average usage at any moment would be about 443 watts, which seems reasonable. I'm no expert, but I would guess you might need a 1kW - 2kW system along with a battery bank and whatever converters/transformers to suit your energy needs. With the power generator this cheap, I'm guessing the total system would be around $5000; $10000 at the max. Totally doable for a 15 year payback(assuming your area gets enough wind).
I think they were quoting numbers for an industrial installation. No home will ever need 250,000 kw.
tumnasgt @ Jun 20th 2008 12:47AM
"I think they were quoting numbers for an industrial installation. No home will ever need 250,000 kw."
Unless of course your name is Al Gore, hell, he probably uses an entire nuclear plant.
john @ Jun 20th 2008 5:04AM
It produces 250kw not 250,000 kw.
The smallest version only produces 10kW.
solu @ Jun 19th 2008 6:42PM
I wonder what the scale is on this thing, wind turbines are more productive and cost effective the larger they get, and this one looks pretty dinky.
Ian @ Jun 19th 2008 9:20PM
goddamn it i go through the trouble and try to comment and nothin.. i well heres a recap.
perspective, put a something we all know the size of next to it then we shall see how big it is.
James @ Jun 19th 2008 10:06PM
The single turbine unit is 10 feet in diameter and 16 feet wide. The largest twin turbine model is 44 feet diameter and 60 feet wide.
HunterXI @ Jun 19th 2008 6:42PM
Funny, I had never thought of a standard wind turbine as a "HAWT". Regardless, I HAVE thought of them AS hawt...
...Just how big are those things? The picture seems to make it seem smaller than it probably is.
TheGasMan @ Jun 19th 2008 6:48PM
"As wind energy becomes a practical necessity"
Where?
Ducato @ Jun 19th 2008 6:55PM
I don't see how the wind would make that thing turn with the blades angled the way they are, they should be rotated 90 deg for maximum efficiency.
Oh yeah and put a fence around it. Whatever
Ian Page-Echols @ Jun 19th 2008 9:38PM
Each one of those apparently flat pieces is like a wing on a plane. They're aimed correctly.
SimbaDogg @ Jun 19th 2008 9:46PM
are you a physicist? maybe an engineer?
bamboo @ Jun 19th 2008 8:23PM
Actually, if you watch some of their concept videos, if they work it looks like an awesome product.
I would like more information on noise output and the wind speeds that are necessary. Like how low of a breeze will get this thing turning.
I just moved to coastal North Carolina, very near the beach, and there is always a good breeze here, and some days it is pretty gusty. This would be awesome as much open space as the area around here has. Could even put some out in the sound/bay, or in some of the farm fields.
Chad @ Jun 20th 2008 10:52AM
Perhaps if you looked at their brochure with the power curve chart in the upper right hand corner your questions will be answered.
http://www.broadstarwindsystems.com/assets/AeroCam1.pdf
It looks like the smallest version (AeroCam Type I) will generate electricity with as low as 4 mph winds.
Dave @ Jun 19th 2008 9:03PM
Like other gadgets, I would love to see a breakdown on material costs and manufacturing for this thing.
I'm no expert by any means, but unless that thing is 100 meters across, I'm not seeing how it's worth nearly $250K
The price needs to be about 100 times cheaper than that.
Steve @ Jun 19th 2008 10:09PM
The total width appears to be 18.5941667 feet according to their brochure. It shows a dimension of 223.13 wide, but does not specify units. However, the brochure shows graphics of them mounted on the tops of office buildings, so surely it can't be 223.13 meters or even feet. Since they're based in Texas I'm going to assume they aren't using the metric system. As far as turbines go that seems like a pretty decent size.
What I'm wondering is, if you had, say, a farm and put just one of these on your land for $250K and pumped the energy you didn't use back into the grid, how long would it take to pay off?
Greg @ Jun 20th 2008 10:13AM
According to their website. There are four models AeroCam Type I, II, III, and IV. There size and rated output vary greatly as inidcated below.
Type I: 10 ft W x 16 ft diam., 10 KW @ 30 mph winds
Type II: 24 ft W x 28 ft diam., 100 KW @ 30 mph winds
Type III: 28 ft W x 36 ft diam., 250 KW @ 30 mph winds
Type IV: 60 ft W x 44 ft diam., 500 KW @ 30 mph winds
Couldn't find a breakdown on costs, but I am sure they vary as much as the size and output, with the cost effectiveness being less for the smaller units.
linuxamp @ Jun 20th 2008 8:30PM
I'll wait for the 1.21 GW model.
spice003 @ Jun 19th 2008 10:15PM
here is their site. those are actually kinda big!

Tim @ Jun 19th 2008 10:16PM
Another great wind turbine design. Development of alternative energy sources and more specifically wind turbines have been moving along at a very fast rate in the last few years.
it only takes a few new designs like this http://www.residential-wind-power.com/2008/06/spiral-airfoil-horizontal-axis-wind-turbine-an-engineering-work-of-art/ to hit the market and residential wind power will become mainstream!
Matt @ Jun 20th 2008 1:19AM
I'll gladly try it out. Just mail it to me here in Canada.....
Greg @ Jun 20th 2008 1:48AM
I run about 300W on average. I would gladly pay $300 and generate all my own power. Jasper (above) thinks we'd have to up that to 1-2kW, and add some bucks for converters and such, but even so that would be great. Now we just need for them to sell the 1kW system as well as the 250kW system. My wallet is waiting...
Ralph @ Jun 20th 2008 1:49AM
Does this mean we can end the gov't subsidies AWEA demands? Can $1/watt do that?
hitsthings @ Jun 20th 2008 1:52AM
Um... appears as though that thing has been bolted onto the sky.
Klaw @ Jun 20th 2008 4:07AM
It doesn't work the same way as conventional turbines - each blade is an aerofoil. The pitch of each blade is controlled and contantly adjusted for maximum efficiency. At any given time, one entire face of the cylindrical layout (almost half the blades) is using the air movement to create lift on each of those blades, which rotates the cylinder.
