35. are you an English major?? do a little math

Wed Feb 26, 2014, 12:01 PM

Feb 2014

100 meter turbine tower
127 meter diameter blades (3 blades 120 degree seperation)

assume safe mode is blades feathered and stopped

worst "safe mode" case: one blade stopped pointing straight down
(100 - (127/2)) x 39.37/12 = 120 ft. Hurricane waves would have to be 120 ft high just to barely touch the lowest blade tip

most likely "safe mode" case: one blade stopped pointing straight up, other two blades stopped at 60 degrees off vertical
63.5 meter blade = 63.5 x 39.37/12 = 208 ft
sine30 x 208 = 104 ft
104 ft + 120 ft = 224 ft Hurricane waves would have to be 224 ft high just to barely touch the lowest blade tips

Offshore Wind Farms Could Knock Down Hurricanes [View all] n2doc Feb 2014 OP

But it would ruin the view on my golf-course! DetlefK Feb 2014 #1

First, 78,000, Wow, that's a lot of windmills liberalmike27 Feb 2014 #48

I would be really conflicted about this theHandpuppet Feb 2014 #2

right justabob Feb 2014 #6

Exactly. theHandpuppet Feb 2014 #10

The turbines would lessen, not prevent hurricanes. antiquie Feb 2014 #9

Yes, yes, yes pipi_k Feb 2014 #43

Except for the part Control-Z Feb 2014 #56

But.... butbutbut wind farms are a scam! sibelian Feb 2014 #3

And giant walls will stop tornados B2G Feb 2014 #4

Sorry greytdemocrat Feb 2014 #5

It says what is possible n2doc Feb 2014 #7

Please greytdemocrat Feb 2014 #12

are you an English major?? do a little math trekbiker Feb 2014 #35

I've tried to put this in perspective by looking at the world's largest off shore wind project. wercal Feb 2014 #24

Agree. Possible, but really unlikely. n/t FSogol Feb 2014 #27

Yeah but those blades fly for MILES when they come off. n/t cherokeeprogressive Feb 2014 #8

if you've never seen a wind turbine blade embedded in 3 meters of hail, miles away from the turbine, dionysus Feb 2014 #11

You two are bad... greytdemocrat Feb 2014 #13

you tryin to cause some kind of kerflunkle? dionysus Feb 2014 #14

Not me. greytdemocrat Feb 2014 #15

Crunchy. The sound of wind turbine blade hitting a house Pretzel_Warrior Feb 2014 #58

... dionysus Feb 2014 #60

Imagine Nawlins shredded by blades from over the horizon, then buried under three meters of hail... cherokeeprogressive Feb 2014 #19

that'd be worse than sharknado! dionysus Feb 2014 #29

Yeah but we're talking about a case where you'd have a cherokeeprogressive Feb 2014 #37

the rifflenado might, just might... be worse... dionysus Feb 2014 #53

Snort! FSogol Feb 2014 #25

You seem to have forgotten about the screaming, tree-climbing coyotes! zappaman Feb 2014 #50

Or vice-versa . . . hatrack Feb 2014 #16

but that's how the earth cools itself leftyohiolib Feb 2014 #17

Pulling energy from the atmosphere via wind turbine would also cool it. jeff47 Feb 2014 #42

It's not just a matter of cooling the atmosphere theHandpuppet Feb 2014 #49

And those are cooled by putting energy into the atmosphere jeff47 Feb 2014 #51

If you really think some turbines could provide these same kind of balances theHandpuppet Feb 2014 #54

Dumb question - wercal Feb 2014 #18

True. n/t FSogol Feb 2014 #26

At some point. The idea is you've sapped the energy from the storm by then. jeff47 Feb 2014 #40

Overspeed protection. AtheistCrusader Feb 2014 #41

They actually turn them off in high wind events Pretzel_Warrior Feb 2014 #59

this could happen warrior1 Feb 2014 #20

More energy in the atmosphere is one aspect of climate change. freedom fighter jh Feb 2014 #21

This sounds like bs to me. HappyMe Feb 2014 #22

Free, clean, renewable energy JJChambers Feb 2014 #23

Yeah right! I bet all those farms who had windmills did a great job in stopping tornadoes as well. Crowman1979 Feb 2014 #28

The best way to knock down hurricanes is to reduce the green house gases in our atmosphere back to Larkspur Feb 2014 #30

They just need to withstand the most powerful winds known? Coyotl Feb 2014 #31

And meanwhile both New Orleans and Manhattan will still be fucked... Spider Jerusalem Feb 2014 #32

Ugly, ugly, ugly, and maintenance could be a big problem, especially in storms. JDPriestly Feb 2014 #33

We should have wind turbines along every coast in this country. Vashta Nerada Feb 2014 #34

Seems like a few decades back packman Feb 2014 #36

So that right-wing nit a few months back was right? AllyCat Feb 2014 #38

but how do we keep them from blowing the earth off course? AtheistCrusader Feb 2014 #39

Oh sure... pipi_k Feb 2014 #46

But, I thought wind turbines slowed the Earth's rotation down. kentauros Feb 2014 #62

Sweet, that means we can bring back Boston Market! AtheistCrusader Feb 2014 #63

Are they out of business? kentauros Feb 2014 #64

There's two or three left in CA and TX that were bought by the employees. AtheistCrusader Feb 2014 #65

I seem to recall they did have good cornbread. kentauros Feb 2014 #66

What would be the unforseen consequences of doing this? Renew Deal Feb 2014 #44

Alternately... pipi_k Feb 2014 #45

�The cost would be zero� ... I'm still laughing over this one Baclava Feb 2014 #47

The electricity would cost 4 or 5 times as much as gas fired generation. badtoworse Feb 2014 #52

There aren't enough rare earth's to build it without new designs. joshcryer Feb 2014 #55

Well, I guess they won't be putting them off North Carolina, then KamaAina Feb 2014 #57

They should build 50,000 off the coast of Hyannis Port Pretzel_Warrior Feb 2014 #61
