Jellyfish Windmill (too good to be true ?)

I co-worker told me about this wind mill. http://www.clariantechnologies.com/main/page_plugin_wind_power.html
The Jellyfish Wind Appliance is a small 36-inch tall vertical-axis wind turbine (VAWT) with a solid-state controller and a variable-speed induction generator that plugs directly into an existing wall socket and automatically generates power whenever the wind blows. The Jellyfish can be mounted on rooftops, wind towers or even existing street light poles - which are already pre-wired to the grid and have the tower already in place! And, it can generate up to 40 kWh per month in moderate winds enough to light an average home using energy efficient light bulbs. With a target price under $400 the Jellyfish would be an affordable option for many households and developing communities looking to harness wind power for the first time. Working in tandem with the existing power grid, the Jellyfish enables large-scale distributed-generation, delivering power exactly where its needed and reducing the demand for costly transmission infrastructure.
It's sounds too good to be true to me.
What do you guys think ?
P.S. 40KWh per month works out to about 55 watts continous. So if it works it would be well worth the $400.

I read an article in ReNew magazine some months ago about 'Guerilla Solar' and plugging small amounts of energy back into the grid via your domestic powerpoint. Love the concept. Part of the challenge was not letting your electricity meter run backwards at the time of being read by the meter reader person. It strikes me that a good solution would be a dirty big incandescent globe and lid switch in the meter box.
So if you're an electricity meter reader person, be *very suspicious* of well lit meter boxes

It is too good to be true, it doesn't exist!
When they get further along in the design they are going to have to redefine "moderate" winds to "high" winds if they expect a 3 ft tall VAWT to make 40 kwh per month.
Light an average home on 55 watts? That's what, three energy efficient bulbs?
Nice idea though...

I also was disappointed it was not about jelly fish.

Need to make your prop design easier or secure? Get a PropMod has crystal, eeprom, and programing header in a 40 pin dip 0.7" pitch module with uSD reader, and RTC options.
Hi McTrivia
I think if you do it officially they give you a fancy electronic meter that records power flow both ways. However this certainly *wasn't* an officially approved technique. In fact it sounds kind of dangerous (perhaps that is part of the appeal).
Back to the topic at hand, surely there are some standards on how much power these generate in a wind tunnel? I know its a complex jump to what you actually produce on site with squalls etc. I have a 2 meter, 3 blade rotor hooked up to a 200watt dc scooter motor sitting in the garage waiting for telemetry so I can monitor what it generates. It'll be interesting to see the distribution over time. I have no idea what to expect.
@Silvie thanks for the comic, very funny and so true...

I wonder tho about special situations, where the lay of the land channels wind over a bluff or up a canyon. That also might be the edge of a house facing the prevailing winds or a city canyon. Most big designs are meant for laminar flow out on a level plain. Gradients of wind can be strong and could change the balance of forces on the fore and aft blades. I'm thinking of my brother-in-law's place on Lake Michigan. The wind hits a 100 foot high bluff and jumps. Put your hand over the bluff and you feel it, but back a few feet it is relatively calm. He installed a traditional wind generator on a tower back inland from the bluff back in the 1960s, but, alas, vibration brought it down within a year and the company that made it in those pioneering days was already out of business.

My computer power supply alone hogs 950watts, This does not include the monitor.
How can company's make these clams?
How do You keep a wind mill in sync with the utility?, And not have an expensive battery array and inverter?
If Free POWER was easy to get , I think one of US would have figured it out by now.

It could probably light my house IF it generates 55W continuously, as that would be 5 x 11W bulbs, and I usually switch off the light in rooms I don't use.
As for getting 55W continuously out of such a small generator...
sounds a bit bogus to me.
And the final; 'plug it into a socket in your grid'...
The power companies will just love that. Dozens or hundreds of these 'more or less synchronized' generators in their grid...
I think they use that 'plug it into the grid' to hide for the user exactly how little power it actually generates...
'It's not our generator that's at fault, it's your increased consumption!'...
That may also be the reason that the generators doesn't work during a power outage.
Of course, as people have high-drain utilities(heated bathroom floors, room heaters, fridges, freezers, PS3 or Xbox360... ) connected to the grid, and that these will suck up all the juice unless they're unplugged, anyhow, is another matter entirely.
