66. I think your information is incorrect, at least for offshore wind turbines.

Everything I read says the carbon payback is quick and the operation lifespan is long.

Example from an Aussie government site:

The carbon payback period varies for offshore wind turbines depending on factors like type and location. Studies have worked out the payback period for offshore wind turbines to be from 5 to 12 months. Offshore turbines can generate clean energy for decades with little emissions. This offsets any carbon produced during their manufacture.

Turbine manufacturers are trying to create 100% recyclable blades for use worldwide. A few examples of this are:
• Siemens Gamesa commencing production of 100 per cent recyclable wind blades for offshore wind usage
• Vestas developing a new method to recycle old epoxy-based wind turbine blades. By using a new chemical process, they can break down epoxy resin into base materials for further use
• several other manufacturers have pledged to produce zero waste wind turbines by 2030.

So, what is your proposed solution?

New Bladeless Wind Generators... [View all] electric_blue68 Jul 26 OP

Except it produces piss poor power levels. Disaffected Jul 26 #1

Well, maybe it can be improved. electric_blue68 Jul 26 #6

physics doesn't work like that. NutmegYankee Jul 26 #7

Seems to me the way you phrased this (re: it's efficiency) was a bit snooty. Poster Diaffected had a similar view but electric_blue68 Jul 26 #19

snooty? NutmegYankee Jul 26 #46

I didn't explain this clearly enough...it's Not about the lack of effeciency electric_blue68 Jul 26 #52

Highly doubtful, Disaffected Jul 26 #14

TY for the explaination. Too bad. I see what u say Omitting the power stats. electric_blue68 Jul 26 #20

I'm guessing the cost/Watt is pretty abysmal. Disaffected Jul 26 #15

There've been backyard vertical windpower generators for years. No vibrating whip action but... brush Jul 26 #36

Believe me you will get a lot more Disaffected Jul 26 #43

I did mention they can be as high as you like, no limitation to height and the bird kill and maintence of huge blades. brush Jul 26 #47

Yes but keep in mind that the power Disaffected Jul 26 #49

Shielding from the wind wouldn't be a factor if the field is designed to space units from blocking each other. brush Jul 26 #58

You said vertical blades "encased in a vertical metal cylinder". Disaffected Jul 26 #60

I didn't say that. Another poster said that. I eant it would be a vertical clindder shapedstructure supported on four .. brush Jul 26 #61

Huh?? Post #36 by Brush: Disaffected Jul 27 #69

vertical cylinder was meant to be vertical structure. brush Jul 27 #70

There were some vertical ones on a windfarm near Tehachapi in Caifornia. MineralMan Jul 28 #76

One of the big disadvantages of vertical turbines Disaffected Jul 28 #80

I did a few. MineralMan Jul 28 #81

Interesting. Technology changing and this time for the environment Deuxcents Jul 26 #2

Clever! And I do like the point that it can go in more places / more versatile. A nice fact too. SWBTATTReg Jul 26 #3

Again, the Skybrator The Madcap Jul 26 #9

It (the interwebs nickname) was mentioned in the article... electric_blue68 Jul 26 #10

Sorry. I was referring to Post 4, below. The Madcap Jul 26 #53

It might depend on the person. 😄 electric_blue68 Jul 26 #11

Well, besides the obvious, it looks somewhat like a metal Saguaro Cactus without arms electric_blue68 Jul 26 #12

Cool! Paint em green and they become almost invisible in the SW. nt ihaveaquestion Jul 26 #29

Aha! Been to the SW, but northern AZ desert. No saguaro. electric_blue68 Jul 26 #32

Seen em in Tuscon and Flagstaff areas... I think they are found at certain elevations. ihaveaquestion Jul 26 #51

Ah, Flagstaff. Interesting... electric_blue68 Jul 26 #56

Ha! Could be. electric_blue68 Jul 26 #21

Cool. Vertical turbines are not new. mahina Jul 26 #16

Ty. It Is the first I'd ever heard of them! And I've paid attention to Renewable Energies since the mid 80's. electric_blue68 Jul 26 #22

Re: wind TnDem Jul 26 #18

Got it, both the bladeless, and typical kinds electric_blue68 Jul 26 #24

I believe TnDem Jul 26 #27

What's the carbon footprint of a wind turbine? CentralMass Jul 26 #31

It's BS, read the article TnDem Jul 26 #37

Ohhh, well...not good for any secondary usage. electric_blue68 Jul 26 #34

New recyclable materials are being researched and are becoming available. CentralMass Jul 26 #30

That'd be an improvement! Ty electric_blue68 Jul 26 #35

Recycling of plastic TnDem Jul 26 #48

Stick with fossil fuels then. I'm sure burning oil and natural gas is much better. CentralMass Jul 26 #54

Thank you. I don't understand why some are so against wind turbines. thought crime Jul 27 #67

No, the carbon payback is pretty quick. thought crime Jul 27 #68

Might there be any renewable power generation method that you would approve of? mahina Jul 28 #72

Hydro TnDem Jul 28 #73

True, but it is facing real problems as rainfall declines. mahina Jul 28 #74

No objections TnDem Jul 28 #78

I don't disagree but compared to what? mahina Jul 29 #82

Fossil fuels are cheaper, but they emit obvious carbon TnDem Jul 28 #79

A welcome innovation... ancianita Jul 26 #25
