Two different wind turbines

Hello,

I've found these two kinds of wind turbines. What do you think about them?

Greetings, Matis

 

dunno matis,

they look expensive, the first one like a funnell makes quiet an impression on the visual landscape.

at one stage i was asking why ventilator type spinners on rooves could not be utilised, as they spin when a bird flies past, so maybe could trickle in power into a dual system, seems those turbines are not prone to obsolescence, like solar and wind generators(propeller types lots of maintenance with unidentified health issues), but the roof spinners don't develop enough torque what ever, there was some development done in this area, but has not taken of, having an alternator run by a spinner, looks less impacting on vision and also less scary for neighbours who have concerns about a propeller unit flying to pieces(the big units have over seas and spread shrapnel for up to 1 kilometer away, dangerous i would say).

if we are going to rely on renewable power, first up it has to be affordable for the lowest denominator, then lets plant habitat first and give second or third place to wind solar farms. i think molleson said renewable will work better in decentralised system, at least there would be room to replace raped habitat.

then the cost, none of solar is getting more affordable in real time, the subsidy pushed prices up, artificially. and as much as we'd like to buy some with wind as well we simply can't afford it very many like us out there.

hear a lot about germany's conquests but somehow the full true picture not emerging would like to hear from the lower class masses, they apparently pay around 36 cents per unit plus subsidise the industry to the tune of around 9 billion dollars, that must hurt the hip pockets somewhere, or do they run a true system of the rich pay so all can live well?

for me i like your research, i would support renewable's if they became affordable to buy, and use as well as replace, the replacement bit hardly mentioned.

with wind turbines they are non directional to the wind they would work without needing to turn into the wind, mechanical action = maintenance and wear and tear.

This one was put on Fremantle Council Building a few years ago i wonder how its going?

...............just googled some more
seems to be doing well

just sent tyre kicker e/mail off about those wind pods, looks like they are installed along a single parallel, no swinging? anyhow maybe the company will give that info.

I love the fact we have so many ideas for electricity generation these days - but can't help but think of the way we still generate mainstream power... its rather like owning an electric car and using it to pull a horse buggy with the family in it...

 

well to be expected the front desk people at that wind generator site have deemed me not worthy of a reply to my e/mail, just the way business is, they ignore possible clients.

and it is probably a very expensive system, be heavy on the roof one would imagine, also the building in west oz wherever that has one probably don't want to say it is not good value at least.

don't electric cars still use coal fired power to recharge them affordably

our unit price artificially inflated this term from 21cents to now 26cents per unit, and people say that is not impacting cost of living, talk about buckets of sand with heads in them.

From their website under FAQ
Probably explains a few things

 

In answer to your other question, Len, page 2 of the 'Product Brochure' states:

thanks grasshopper and mark,

still does not excuse them being off handish.

the only thing is how much power does a home need then how much will this cost, also add in batteries, so 3 kwh could equal nearly $17k + unknown heritage inverters and some wire does that include fitting.

anyhow you both defended the company nicely, still unaffordable for the masses.

len

 

its not as unaffordable as coal

 

Just wish Abbott and Co thought the same. Climate Commission gone, Clean Energy Fund abolished, no Minister for Science. Now they're going after the wind farms. Big Coal really have them in their pocket.

 

don't know how you work that one out grasshopper? coal power is being forced up artificially, and you seem to forget if people can't afford renewable's then what will you do for those people? also higher power prices will push jobs off shore, already happening, qld and nsw at least their economies are based on coal mining, so makes it an absolute stupidity to stop coal fired power and mine and sell it to countries who are only really paying lip service to pollution. and there is still nothing outside of hyper theoretical theory to say there is a climate change caused by heavier than air CO2.

you ahve not like many others offered an acceptable affordable already up and running replacement to coal fired power. so time for the feel gooder's to put money where mouth is, we cannot afford and renewables, we can't afford the ever artificial increases in power, so where do people like us go? can you take that on board, we live in the real australia.

for me struggling under a failed public health and dental system, having the climate condition was not using money wisely, while aust' can't look after the health of its people, if they now broaden GST that along with power and fuel will make food even more expensive, imagine a society that taxes people for the food they need. big wind farms will jsut rob our ability to replant habitat and won't save us.

think about it, any of you could end up where we and the voiceless masses are.

how can others call for a united community when looking after all is not on the table.

on top of all that support is given to companies who have no repore with customers, sorry no excuse for them, so then if buying renewables becomes terribly affordable there is no one out there i would feel comfortable with, dealing with them, if they simply can't recognise that they received an e/mail, bad business all round.

We cant afford not to stop burning coal
Where do we/future generations go when we destroy this planet because we want "cheap" power now?
Coal is massively subsidised, Government (our) money built the stations, wires, ports, roads etc to dig, burn and sell it.

No one is saying stop the coal tomorrow, but it would be great, but lets start building the alternatives today, so we can kill the coal industry before it kills us.

You seem confused re economy and pricing
The price of anything is based on peoples ability to pay

Maybe if you calculate buying a share in a community owned wind farm, were it involved minimal investment compared to building a a unit with batteries on your property, disregarding the existing paid for electrical infrastructure is both wasteful and expensive.

Think outside the box Len, a little more big picture and a little less astroturf waffle.

 

i dunno grasshopper, is this the true colour of green shining through.

i am not confused about what lower socio economic can afford, and it doesn't even fit into your theory. as there is no real on the ground evidence of heavier than air CO2's impact on anymore than visible air quality eg.,. china, the US, sydney and melbourne maybe, and the fact that in total aus' puts out less than 2% of the total world CO2, which si only about 22% of the air mix, and china pumps in 20%, what real difference would there be for making teh poor poorer? almost negligible.

we are the future generations that were set in play 30 to 50 years ago, and as things aren't really changing that dramatically then in another 50 years time we will simply have more starving populations, dying from various fixable health problems.

if coal is so subsidised then move that money to your as yet long way from reliable development renewables, and don't push power costs up like it is a good indirect tax and the money goes where? wasted.

i am living outside teh box grasshopper, and you then insult me by calling my concerns astro turf waffle.

a share in a community based farm give over grasshopper, we flat out paying bills don't have spare money even pretend money like yuppies have. and we are in rural north of a centre how does that wasted money then help us, reality grasshopper not sweet fairy dreams, would be oh! so easy and pretty though those rose coloured glasses if all cared about all and we all tip toed through the daisies. that waffle should if nothing else impress you, but not to coming outside your box and thinking latterally

anyhow mark now you can see why any dream of a united community is just that a bad dream.

at least you admitted one fact that decentralised solar/wind is expensive and wasteful, yet centralised is more so unreliable and wasteful.

len

 

That is precisely what the Clean Energy Fund was doing before Abbott axed it. And they had been achieving real results.

 

i'll take your word on that eco'

but solar alone was not getting anymore popular among the masses nor was it getting more affordable, that subsidised money is out of sight and out of mind we would have no idea what sluch fund it may have gone to, remember those we rely on to be honest and above board are far from that these days. and pushing power prices up is a hidden tax and all pay that extra so even if you have solar you are paying twice.

still very bad for your business should you have one to ignore any customer.

Ok lets suspend belief for a moment.

Even if the whole human induced climate change is fringe or non-existent, I contend that non-polluting renewable and sustainable energy sources should still be a priority, if only to stop the pollution of the air and our waters ways. In order for these to be developed we need investment and a fair playing field for them to thrive in. The current Australian government is clearly not interested in that. Which means they must be in the pockets of the big miners. There is no other rational explanation for their wanton disregard for the environment and the wishes of the people. You cannot develop alternatives if you put up barriers to them let alone fund them.

The rising costs of electricity are not from any carbon tax (for which the so called 'poor' were compensated), it is from corporate greed. They raise the prices because they can. If you remove the subsidies from coal again the costs to the consumers will increase.

 

i agree grahame, we have all had these chats before yet we are in the doldrums no wind in any sails, make renewable affordable and we at least would scrape some money together to buy some, i do not however believe in wholesale subsidies like we have just gone through a huge waste of money, all that happened was it all got dearer as manufactures through to installers reckoned hey deserved some of that lolly. the end user got little. and in all feel good chats on the topic none want to talk about the eventual replacement cost of the whole system. we would never buy a property with solar as we would have no idea when we would be up for the unsubsidised cost of replacement, even though the assumed value of the stuff is added into the price of the property.

want to shut coal and manufacturing industry down, prepared for the dole queues to get longer, all product will be imported, then get the renewables up and running an reliabley affordable.

i'm with you like i was with mark, but usually the going gets too tough.

let's take charge of our lives all of us together, sack the greedy in power, make the wealthy pay real taxes.

and i did not say remove teh subsidy from coal, waht i am saying is it is not helping teh renewable industry at all.

Germany has more expensive power, high wages and not as much resources, yet manufactures and export more than Australia
