Im trying to get the word out about what i consider a break threw with the VAWT the SRWT will keep you up at night thinking of places to install them No one has done this yet and i am trying to be careful not to just let it out to anyone i have bean told its brilliant but need capital to bring it to the world. Does anyone have any suggestions .

Enough with the poor birds. Take a look at the front radiator of your car, or the next truck stop, check out the front radiator of the all the trucks lined up. If you try hard enough you’ll always find negatives to any thoughts of change and inovation. Is anyone hanging up their car keys yet?

apparently, http://got2begreen.com/jet-wind-turbine-4-times-more-efficient/ may no longer be a valid link…

(There’s a video explaining the concept here.) — not!

Birds don’t get “sucked” into a wind turbine as it is not under power and pulling the air in like the backside of a house fan. Instead the blades are turned by the force of the wind pushing on them so there is never a vacuum effect that could overpower the flight of a bird. Also the blades are close enough together to seem almost solid. The wind pushes on a solid wall but birds can see the wall and fly around it. The traditional three bladed windmill is mostly open air that birds think is safe because they don’t understand the blades predictable path of travel any more than a creature of the forest understands a cars predictable path of travel on the road.

interesting design…

for a few years, i’ve been wondering why the wind-catching funnel isn’t on top of the mast and the generating turbines down near the bottom of the mast where they’d be so much more accessible for maintenance, installation and upgrades.

i assumed the hydraulic losses could be compensated for by good “trumpet” design and vertical or horizontal-shaft turbines near ground level could be protected from debris intake.

whatever…

That design woud be great for a sailboat if they could scale it down.

Due diligence should include the Diffuser Augmented Wind Turbine (DAWT) research work supported by the US-DOE going back to ~ 1977 and serious start-ups like Flow Energy in New Zealand around 1992. The results have always been that the cost of the diffuser structure make DAWT’s more expensive than conventional wind turbines. Also, the claims that DAWT’s can exceed the Betz Limit of 59% efficiency have failed to be bourne out in practice. Small scale DAWT’s have been brought forward by Enflow, TurbodynamX, and a number of others. None have been commercially successful.

Cost, expense, infrastructure … I’m ready to have a look at one ( or more ) installed near 46ºxx’xx.xx” N 124ºxx’xx.xx” W on a major sessional flyway. Never seen a bird yet fly into something it could see & is stationary ! Though the ducted fan concept increases efficiencies, it’s no 747 ripping along, down the runway, sucking in all it can.

“to keep birds from getting sucked in, which is one of the biggest complaints about wind energy” … and one of the largest myth’s … pet, overfed house cats kill more birds than do wind turbines … that’s the info coming out of N. Europe.

It looks great! I’d like to see a mesh screen on the intake side (like a room fan or propeller guard) to keep birds from getting sucked in, which is one of the biggest complaints about wind energy.

Great story guys. I was looking for a press release on the MIT site for the Clean Energy contest winner, but couldn’t find it. Then I thought, “I bet Xconomy has a story on it.” And sure enough. Got really excited about the Al Gore scoop, too. Great job! You guys rock.
