Silent wind Turbines.

Will we see these on the houses and in gardens here?

It's the sort of thing i've been looking for, i've been quoted around £2,500 for a turbine thats has the same production (dependant on wind) but is significantly bigger and thats what has put us off. It would also be free standing, I wouldn't put it on the house though, you would surely hear vibrations.

These are all very well, but I thought you need a big garden, live in a windy location & get planning permission to put up a bloody great pole/tower.

I suppose someone could stick them on the tops of high rises.

Off the top of my head I think you only need planning if they are going to be over a certain height.....10-15m is ringing bells but I might be wrong.

I don't think I've got space in my postage stamp garden to mount guy ropes to support something that tall even if it didn't need planning.

Good video. But it didn't mention cost of maintenance or the kick out mechanism.

I have seen rooftop turbines before.. In bits.

or the kick out mechanism.

Is the kick out the brake?

Looks interesting but at 1.5m I think it would be too large to fit on a house roof.
Some time ago there was a TV aricle on a small wind turbine. It spun vertically (like the top vent on a refrigerated van) and was small enough not to look out of place. One scene showed several on a roof to make up the required output. I have searched but have yet to find who makes it - just wondered if any one can point me in the right direction. G

Well, those of us living on the coast in the north east certainly have plenty of wind! Interesting.

Found they make a smaller unit 75cm across

Specs and availability​

While there is no current UK distributor for Archimedes, it is possible to export the turbine from its Indian manufacturer Archimedes Green Energies.

It is currently available in two sizes, with a third size – with a diameter of just one metre – is on the way.

• AWM750D – 75cm diameter with a rated output of 100 W and a maximum power of 140 W.
• AWM1500D – 1.5m diameter with a rated output of 700 W and and a maximum power of 550 W.

For both models the rated output is measured at a wind speed of 12.5 m/s.

The generator of both models has a 3-phase alternating current output.

The turbine has been tested at wind speeds up to 50 m/s.

Mieremet says: “The annual output depends on the local wind conditions as well as on the height of the installation. Low available wind speeds will result in a low annual output.

“The estimation we make, are based on weather data from Meteoblue. Meteoblue provides weather data for all locations on earth, with an accuracy of 95% (according to Meteoblue). All over the UK wind conditions seem good for harvesting wind energy. You can check the wind conditions yourself for any location (or coordinates) by filling out the ‘search location’ bar at the Meteoblue website.”

Pricing​

For pricing, Mieremet says: “We recently opened a production facility in India. The prices for the Indian made products are $1700 [£1342 approx] for the AWM750D and $3200 [£2526 approx] for the AWM1500D”.

This excludes delivery and custom duties.

Not really, a brake is not generally enough (that's generally for overspeed in normal conditions) they need a device to kick them out of the prevailing wind.

I guess they have thought about it, but they haven't mentioned it as far as I can see.

They too have spun into the "failed" heep.
