Screwy-looking wind turbine makes little noise and a big claim

Although it’s getting increasingly common to see solar panels on the roofs of homes, household wind turbines are still a fairly rare sight. If Rotterdam-based tech firm The Archimedes has its way, however, that will soon change. Today the company officially introduced its Liam F1 Urban Wind Turbine, which is said to have an energy yield that is “80 percent of the maximum that is theoretically feasible.” That’s quite the assertion, given that most conventional wind turbines average around 25 to 50 percent.

So it creates a mini tornado within its design?

The writer of that article is an idiot. (FTR, it is no more efficient than any other modern wind turbine)

Having said that, I can see a few practical advantages to the design,along with some potential disadvantages.

“Additionally, the design is claimed to keep it always pointing into the wind for maximum yield.”

Now why didn’t those conventional wind turbine designers think of that?

Pigs Arse

Going by the figures, I’d need about 5 of those turbines ON MY ROOF to cover my average daily kw usage.

I wonder how much one CO$T$

I know someone who used to work for a firm manufacturing rooftop wind turbines. He now works in designing pumps for use in extreme environments for the mining industry. Cost per unit power for rooftop wind turbines was a problem, performance increases greatly as diameter increases which is why you see big ones rather than small ones.

You can buy small wind turbines from Jaycar.

I think Hockey is interested in Screw Wind Turbines, I believe he uttered those words.

He knows a lot about science

Also location-wise, domestic roof tops are even more hopeless for wind than they are for solar.

I suspect there’s apples and oranges here and that the 80% is 80% of the Betz limit while the 25 – 50% is of the total energy content.

As I understand, and if correct I’m sure many others here do too, the main design issue of urban wind turbines is for them to be able to start and stop quickly to be able to get useful energy from gustier, more unpredictable wind conditions compared to the large-scale turbines that have sugnificant ramp-up times, but can take advantage of the stronger, steadier winds where they are located.

Those percentages are basically meaningless as an aid to comparison.

The single most important statistic is $ per mean watt.
