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.

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.

See what I did there

Wow, those outputs are rubbish

100w at 12.5m/s?
That's 0.1kw/h at a constant wind speed of 30mph

So if it was windy as hell all day, I would get 2.4kw out of the system (minus inefficiencies from the inverter etc), or the equivalent of saving about 50p in leccy

The small one won't even cover your standing charge.

I guess it would power lights, a fridge & phone charger though if you had it on the roof of a caravan parked in a typical seaside clifftop site

output is insignificant, but depends on cost how much would 4 of these cost compared to solar panels?

if it was any good industry would have scaled it up and be using it surely?

Well to put it in context, last year I had a 4.5kw solar panel system installed, with a 10kw battery and inverter for £8k
So using the larger of the two turbines mentioned above, I'd need 6 of them. At £2500 each, I'd be in for £15000 without accounting for mounting poles, inverter, house wiring and a battery system.
Plus I would suggest that in most of the uk, we get more sunshine than we get 30mph wind throughout the year.

I think these type of 'domestic' turbines are designed more to augment other forms of power rather than replace, I still haven't got my solar panels but when we do I would also be on the look out for a small ish turbine to charge the battery at night or on days with low light levels. Had a few of those recently down here in Cornwall........

Well you might be surprised. At least wind turbines work at night, no matter how many solar panels and generating capacity you have, when the sun goes down you're getting nowt. People who talk about their solar installations are very much like gamblers, they only tell you when they win. Mate of mine boasts how little his electricity bill is in summer thanks to his solar, but he's very quiet over the winder months... Lots of real life experiences, positive and negative, on the web so like heat pumps, these things can work but needs alot of thinking about the installation. One example below from someone who's been running both wind and solar for a long time suggests that solar is not quite as good as it is often advertised and wind is actually probably a better bet all year round if you can go that route.



Of course there is always dunkelfloute which has caught out Germany. There are a couple of wind turbines in sight of where I live and I often Montor them and through November we had a period of almost 3 weeks where they hardly turned a blade. Which is fine when you have a system that can generate power via may different sources, but if you were relying solely on wind (or solar) then there are gong to be significant periods where you will be without power. And batteries only give you very very temporary buffering. Imagine a battery farm that had to store and then deliver power for three weeks during a period of dunkelfloute...

Wow, I bet the salesman/woman doesn't mention that figure when they are selling you solar.

yep well thats sales for you...Apparently my last car was good for 56mpg and my current EV good for 330 miles of range.... more like 42mpg and 230 miles respectively. Actually with my EV its worse that as the manufacturer recommends staying within 20% and 80% to maintain battery health, so if you do that it cuts down the range to barely 140 miles.
