STLBILL Posted December 27, 2006 Report Share Posted December 27, 2006 What Are those bad boys sitting on? Concrete? If so I bet there is some narly grade beams/steel in there! "There are approximately 150 cubic metres of concrete and 21 tons of rebar (reinforcing steel) in the wind turbine's foundation.", but surely it would depend on the design, environment, and a lot of other stuff. Here are some links with pictures of the foundations being built and discussing it in detail. One has a technical drawing that should answer most of your questions: Foundation Information Resource 1 Foundation Information Resource 2 Foundation Information Resource 3 (Just data - No pics) And if you want to know about off-shore wind turbine foundations take a look here: Off-Shore Foundation Resource 1 Quote Link to comment Share on other sites More sharing options...

Ah, you just need a couple modified Banshees, a few pair of sand tires and some premix. :thumbsup: Edit: And I just realized I sort of hijacked MM's thread.

Animalman294 Posted December 27, 2006 Report Share Posted December 27, 2006 1.89 Million a piece!!!!!!!! I wonder how long it will take them to recoup that cost and start making a profit on their investment..... Quote Link to comment Share on other sites More sharing options...
MILO Posted December 28, 2006 Report Share Posted December 28, 2006 i've never seen any wind mills like that, but i've seen tons of blade parts shipped out before. we made them at my work where we make pultruded fiberglass reinforced composites. ever seen the fiberglass step ladders, shovel handles, structural shapes, yeah, that kind of stuff. (creativepultrusions.com) anyway, we made tons of blades for a while, mostly going across the pond. pretty neat stuff though. amazing how big they actually are.

Mullet Man Posted December 28, 2006 Author Report Share Posted December 28, 2006 (edited) 1.89 Million a piece!!!!!!!! I wonder how long it will take them to recoup that cost and start making a profit on their investment..... it doesnt take very long at all! the bigger windfarms would obviously be cheaper since it is a 'bulk operation' once they are payed off, it is cheap cheap energy, all they have too pay is land rental fee (the ones here are around $5,000 a year per tower to the land owner, so multiple towers on one owners property works out pretty good in their favor) What Are those bad boys sitting on? Concrete? If so I bet there is some narly grade beams/steel in there! yep, huge pads of concrete, they extend about 16ft fron the edge of the tower, all the way around it. What are you doing with fiber at a wind farm? You cannot send electricity over it, so it must be a control or monitoring system of some sort, eh? I did read about some research to send electricity without wires (not arcing). Maybe you're doing top secret research for them... all for control sensors, so the blades know when too turn and when too stop at the point they reach the most wind pressure. and for diagnostics of how the inner equipment is operating You don't want to work for "Crinkle and Destroy" :cool: . They are a contractor we use alot at work. Do you know who owns that wind farm? I work for ComEd as a directional borer and have not heard of these so I would suspect they aren't ours. i did work for Henkels for a while. now i am with Michels pipeline (they are out of WI) i work out of LU196 not sure who owns it. i believe the power is just being sold cross country ('on the grid') why so many people are against this stuff, no real benefit to the locals.

ReBall Posted December 28, 2006 Report Share Posted December 28, 2006 Dude if you had that thing in my front yard here in San Diego right now you could make some bucks!

STLBILL Posted December 28, 2006 Report Share Posted December 28, 2006 (edited) 1.89 Million a piece!!!!!!!! I wonder how long it will take them to recoup that cost and start making a profit on their investment..... "....completing a 1.65 MW turbine-sufficient to power some 500 homes...." Source: USDA (www.usda.gov). "Wind Turbines have a designed working life of 20 to 25 years and require very little maintenance during this time." Source: Macfarlane Generators (www.macgen.com) So how much do 500 rural homes pay for electricity for 20-25 years? i've never seen any wind mills like that, but i've seen tons of blade parts shipped out before. we made them at my work where we make pultruded fiberglass reinforced composites. ever seen the fiberglass step ladders, shovel handles, structural shapes, yeah, that kind of stuff. (creativepultrusions.com) anyway, we made tons of blades for a while, mostly going across the pond. pretty neat stuff though. amazing how big they actually are. Merrium, Webster and I would like to know what the hell a pultrusion is? :shrug: EDIT: Nevermind. I found it on your company's web site. In retrospect I do not feel so bad because it is a "frequently asked" question. Merrium and Webster can find out for themselves someday soon. :yelrotflmao: Edited December 28, 2006 by STLBILL Quote Link to comment Share on other sites More sharing options...

STLBILL Posted December 28, 2006 Report Share Posted December 28, 2006 its cool, you're on topic atleast and posting some good links :thumbsup: Thanks. I have to say I've learned a bit from this thread! I especially like the site where you can see how much electricity is being used in the Midwestern United States right now. Was 65,000 Megawatt/Hours when I looked. I gotta turn some lights off. Damn! Let's see what did that nutty professor need in Back to the Future? 1.21 Gigawatts!?!? :ermm: Quote Link to comment Share on other sites More sharing options...
CFM Posted December 28, 2006 Report Share Posted December 28, 2006 Thats pretty Damn hardcore! I'd hate to be the guy digging the hole lol just kidding. I'd love to be the guy digging that hole in a big ass machine making union pay..... And the contract for 20-50 years, with a 5k/yr fee for putting it on your land... Heck, If I had 400-500 acres I'd be retired. Quote Link to comment Share on other sites More sharing options...

tithead Posted December 28, 2006 Report Share Posted December 28, 2006 where do your tirbines come from? over at home, the HQ is in denmark. its a company called "Vestas" that assembles them, etc all over europe and even in the US and Canada. i have seen these things come in/leave the docks in edinburgh.... the trucks that haul them are huge! and the flatbed trailers on the back streach to well over 40ft. maybe even 50ft. are you building the 120ft ones???

STLBILL Posted December 29, 2006 Report Share Posted December 29, 2006 I'd love to be the guy digging that hole in a big ass machine making union pay..... I think it is tough to find work when the weather is bad which effectively lowers your annual salary. There is a Cat D-11R and a D-9N dozer that have been sitting in a muddy field near my place for over a month. They are building new houses. Another D-6R is stuck pulling a compactor (giant lawn roller with spikes). I think the big snow and subsequent melt 5-6 weeks ago caught them unprepared and now they are waiting for it all to dry or freeze up to continue (my guess). And the contract for 20-50 years, with a 5k/yr fee for putting it on your land... Heck, If I had 400-500 acres I'd be retired. A little like selling mineral rights, except this is theoretically unending. Now I know this is too deep for most of you, but if you extract the kinetic energy from the wind the air behind these things should slow down (and spread out). My vision if of some yet undiscovered crisis like the "butterfly effect" in reverse. I guess what I'm thinking is if you put up enough of these things could you stop weather patterns from shifting? I know... too deep for the HQ folks... Click here for an illustration if you are a true geek... :ermm: Quote Link to comment Share on other sites More sharing options...
