1kW Wind Turbine with at wind farm

[leamyelectricinc1]

very cool.

[tatsuko1]

is this why our energy bills are going to shoot up

[HomeWindTurbines7]

It's a good looking turbine. Wow, very nice but that's a great deal of blade noise compared to my wind turbines on my roof are much quieter than that. Mine won't chop noise like that, even in the video with a 60mph wind storm.

[Gadabout96]

The noise you are hearing is the engine of the cherry picker that was used to install the turbine....

[pondman27]

Noisy isn't it?

[proverb311031]

That small wind trubine need to have two sets of blades to get rid of that noise, plus it would produce twice as much energy!

[lisboa6]

.

how much costs each one of the other large turbines????????

.

[SatoTM2]

zephry kW??? i think thats a 400watt

[kdc43]

I now realize where all this wind is coming from. It's these Giant Fans going up everywhere!! I bet it's these commie-alqada terrorists! They turn these fans on "High" and blow up some wind storms, tornados and hurricanes. Now that America has a muslim "green" president....he gonna blow the USA clean off the Earth!!!!

That's truly amazing! I slashed my electric bill in half! look here: solar.xfollow.me (Copy to your browser's address bar)

Both nuclear plants and wind turbines are safer then continuing to give billions to the middle east, think about it.

[Redshift21]

According to who you believe the world has reached "peak oil" or will reach it within our lifetimes, energy, goods and services are going to increase in cost unless we bite the bullet and follow a much more aggressive renewable energy policy here in the UK.

[Kangarupe]

Shit, and here in America I WISH we had a renewable energy plan like you guys do over there.

[Redshift21]

We have what looks like a plan in much the same way as I have what looks like a p***s, neither are big enough or fit for purpose ^_^

[BarneySaysHi]

This thing sure makes a lot of noise. Doesn't that drive you nuts?

[Redshift21]

You need to read the other posts and the description alongside the video ^_^

[scotthall82]

hehe cool video. but im so confuised on how wind power works. the first little one u had on video is that connectd to a power box? and does this box store the electricity? lets say u had 2 days of no wind does that mean you will have no electircity? and also those big bi ones. how can wind be able to spin them? they look so heavy and strong. thanks

[recordcrazy23]

the turbines generate the electricity which is usually stored in dc batteries and converted to alternating current, or they're connected to the grid. you would not lose power if there was no wind for two days. there are back up systems for that.

[tamilmannan]

how many kw u need to power one house?

[lisboa6]

two off thoose 2kw (or just one) you have energy for everything

[Teratornis]

Go to Wikipedia and read the Wind power article. It has a good section about intermittency. The wind has no difficulty turning even the largest wind turbines; even though they are massive, they present a large surface area to the wind, which generates a correspondingly large force. The rotors are also symmetrically balanced, so the wind can easily start turning them.

I know that if you google the Airdolphin it takes you to a company called Semplice Energy based in Reading, England

[ranyerebrc]

Where I can buy a turbine of these here in Brazil? which the price in USS?

[Zitronekopf]

It's hard to tell, but does this one have just the standard 3 blades or does it have more?

[stuartsjg]

Hi,

The frame rate of the video makes it look like there are many blades when there are only 3.

Thanks,

stuart

[vicmeuk]

Superb I`m all for this Turbine Fun! One thing that needs done is.....PWM load dump .......

I think a dump is a waste of energy....I hope in the future we can utilise the waste power into something more useful too.

[stuartsjg]

Hi,

Thanks for the positive comment :)

The dump load is the intended energy usage. It was installed in a file store room to replace a wall heater which was used to keep the dampness away form the files.

Replacing it with a wind turbine removes the need for the wall heater.

Ironically, the wall heater was powered from Multi Megawatt windfarm anyway so really there is no carbon saving only another few kWh/PA for the national grid.

[vaultmantk]

It looks like it produces a lot of power, but it seems so loud, I wouldn't want to go outside.

[stuartsjg]

Hi,

Please be aware that the turbine noise is mostly drowned out by the High Access Lift. You can just about hear a swish-swish like a rope being swung through the air - this is the turbine. Most the noise you hear in the video is the 2.5L Diesel engine of the high-lift and the wind in the microphone.

Hi Stuart, I was looking at the video and see weird regarding the power output. One meter reads 27.55 v dc while the shows 2.77 Amps? How is it making 700

watts?

Regards,

Diego

[stuartsjg]

Hi,

Where you say 2.77Amps (left black meter), the meter does not say amps, but volts.

There is a 100A clamp probe on the turbine output which outputs 0.1v/Amp, so 2.77v on the meter means 27.7Amps. The other meter (Right, yellow meter) is measuring the output voltage.

Also, sometimes the power overlay doesnt quite line up frames which may cause confusion.

The noise is the PWM load dump which dissipates the power as heat for space heating.

[vaultmantk]

oh... ok

[col1n1234]

Hi is there any vibration noise from the wind generator that transfers down in to the house? thanks Colin

[viinikka]

Nice shooting, I like the slow reveal of the wind farm. What was the buzzing noise audible when you were inside the building looking at the output?

[stuartsjg]

Hi,

Thanks for the filming compliment. The high access hire company and the guy that was operating the lift were the hire company Sony used to film the exploding paint on the high-rise buildings advert for Bravia so he knew how to move the platform in a camera friendly way :)

[stuartsjg]

The buzzing is the load dumps, as the batteries were full the excess energy goes to the PWM load dumps which tend to buzz. They are not needed for most installations, they were using the heat to keep the chill out of a paper file store however.

[fukalotfukalot]

Great machine!! but what is the difference with the vertical ones, less noise? I live in Dominican Republic and I'm seriously thinking of alternative energy, electricity bills only get worse every month, it's ridiculous

[stuartsjg]

Apologies, the video aspect has not converted properly in You Tube, it should be 16:9 but its not showing correctly.
