But then some people don't want that because of land condemnation to build lakes,...TVA has produced trillions of megawatts since the late 1930's.

New Bladeless Wind Generators... [View all] electric_blue68 Jul 2025 OP

Except it produces piss poor power levels. Disaffected Jul 2025 #1

Well, maybe it can be improved. electric_blue68 Jul 2025 #6

physics doesn't work like that. NutmegYankee Jul 2025 #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 2025 #19

snooty? NutmegYankee Jul 2025 #46

I didn't explain this clearly enough...it's Not about the lack of effeciency electric_blue68 Jul 2025 #52

Highly doubtful, Disaffected Jul 2025 #14

TY for the explaination. Too bad. I see what u say Omitting the power stats. electric_blue68 Jul 2025 #20

I'm guessing the cost/Watt is pretty abysmal. Disaffected Jul 2025 #15

There've been backyard vertical windpower generators for years. No vibrating whip action but... brush Jul 2025 #36

Believe me you will get a lot more Disaffected Jul 2025 #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 2025 #47

Yes but keep in mind that the power Disaffected Jul 2025 #49

Shielding from the wind wouldn't be a factor if the field is designed to space units from blocking each other. brush Jul 2025 #58

You said vertical blades "encased in a vertical metal cylinder". Disaffected Jul 2025 #60

I didn't say that. Another poster said that. I eant it would be a vertical clindder shapedstructure supported on four .. brush Jul 2025 #61

Huh?? Post #36 by Brush: Disaffected Jul 2025 #69

vertical cylinder was meant to be vertical structure. brush Jul 2025 #70

There were some vertical ones on a windfarm near Tehachapi in Caifornia. MineralMan Jul 2025 #76

One of the big disadvantages of vertical turbines Disaffected Jul 2025 #80

I did a few. MineralMan Jul 2025 #81

Interesting. Technology changing and this time for the environment Deuxcents Jul 2025 #2

Clever! And I do like the point that it can go in more places / more versatile. A nice fact too. SWBTATTReg Jul 2025 #3

Again, the Skybrator The Madcap Jul 2025 #9

It (the interwebs nickname) was mentioned in the article... electric_blue68 Jul 2025 #10

Sorry. I was referring to Post 4, below. The Madcap Jul 2025 #53

"Skybrator" mahatmakanejeeves Jul 2025 #4

It might depend on the person. 😄 electric_blue68 Jul 2025 #11

Well, besides the obvious, it looks somewhat like a metal Saguaro Cactus without arms electric_blue68 Jul 2025 #12

Cool! Paint em green and they become almost invisible in the SW. nt ihaveaquestion Jul 2025 #29

Aha! Been to the SW, but northern AZ desert. No saguaro. electric_blue68 Jul 2025 #32

Seen em in Tuscon and Flagstaff areas... I think they are found at certain elevations. ihaveaquestion Jul 2025 #51

Ah, Flagstaff. Interesting... electric_blue68 Jul 2025 #56

I know what that is Maru Kitteh Jul 2025 #17

Ha! Could be. electric_blue68 Jul 2025 #21

But not nearly as useful, Disaffected Jul 2025 #45

Looks like a Bezos rocket sort of... The Madcap Jul 2025 #8

Cool. Vertical turbines are not new. mahina Jul 2025 #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 2025 #22

Re: wind TnDem Jul 2025 #18

Got it, both the bladeless, and typical kinds electric_blue68 Jul 2025 #24

I believe TnDem Jul 2025 #27

What's the carbon footprint of a wind turbine? CentralMass Jul 2025 #31

It's BS, read the article TnDem Jul 2025 #37

Ohhh, well...not good for any secondary usage. electric_blue68 Jul 2025 #34

New recyclable materials are being researched and are becoming available. CentralMass Jul 2025 #30

That'd be an improvement! Ty electric_blue68 Jul 2025 #35

Recycling of plastic TnDem Jul 2025 #48

Stick with fossil fuels then. I'm sure burning oil and natural gas is much better. CentralMass Jul 2025 #54

Thank you. I don't understand why some are so against wind turbines. thought crime Jul 2025 #67

Agreed ProfessorGAC Jul 2025 #77

Wind farms offset their carbon footprint in 2 years of operation NickB79 Jul 2025 #62

Incorrect TnDem Jul 2025 #63

No, the carbon payback is pretty quick. thought crime Jul 2025 #68

Might there be any renewable power generation method that you would approve of? mahina Jul 2025 #72

Hydro TnDem Jul 2025 #73

True, but it is facing real problems as rainfall declines. mahina Jul 2025 #74

No objections TnDem Jul 2025 #78

I don't disagree but compared to what? mahina Jul 2025 #82

Fossil fuels are cheaper, but they emit obvious carbon TnDem Jul 2025 #79

A welcome innovation... ancianita Jul 2025 #25

I work in this industry, live among the wind turbines and in a major migratory route for birds between Canada and SA. Sogo Jul 2025 #26

Ty for info. As NYC'r I do know about tall buildings w mirrored windows, and bird problems. electric_blue68 Jul 2025 #38

From the headline, I expected to see a cartoon of trump. n/t spike jones Jul 2025 #33

Heh...i was going to make a comment about turning his comments ie hot air into energy...at least he'd be useful electric_blue68 Jul 2025 #39

There are plenty of them out there. spike jones Jul 2025 #44

So it looks like a big vibrator standing Figarosmom Jul 2025 #40

I think they're rather rarher lovely but u can see problem pointed out... electric_blue68 Jul 2025 #42

It's rather a shame that this sort of thing is taken seriously. NNadir Jul 2025 #41

Thank you for this welcome dose of Reality. ancianita Jul 2025 #71

Just did a Google image search. I can see the jokes flooding in!! :-) nt LAS14 Jul 2025 #55

No kidding! electric_blue68 Jul 2025 #57

Innovation in the wind industry is incredible. thought crime Jul 2025 #59

Yes, and TnDem Jul 2025 #64

I think your information is incorrect, at least for offshore wind turbines. thought crime Jul 2025 #66

5 months payback I think... mahina Jul 2025 #83
