In the movie Amelia they give you impression that she knew how dangerous and almost impossible it was to navigate that trip. Why did she try anyhow ?
A menace?
Hardly but…Well, birds, including some protected raptors, have been known to get chopped up in the blades.
Also, a TV station reported that its broadcast signal was disrupted after a wind farm was built nearby.
They received some sort of settlement for upgrades and changes.
I don’t know the science involved (perhaps the construction of the blades?), but it happened.Aldo, the wealthy, liberal eco-friendly area of Martha’s Vineyard in Massachusetts, successfully lobbied against an offshore wind farm in the basis of esthetics…so the old adage “not in my backyard” is alive even for progressive ideas.
I’m not against them, but I have seen some nice areas marred by them, so have a bit of a concern that they are being promoted (or pushed) by people who want the energy but don’t want to pay the price…in the terms of degraded esthetics.
I am wonking on my third prototype of variable pitch H-Darreius..it ought to beat the HAWT props with a clear margin in efficiency…and simplicity..is also lower and quiet. It rews really high..TSR 3 at a low wind speed.
Jumpers hang on the aluminium struts…and due to the absence of the seats they pack them full…and create a CG problem.
This Piper Navajo carried 12..of which 11 died: https://www.dropzone.com/articles/ne…s-eleven-r913/
It is typically 6-9 seater: https://en.wikipedia.org/wiki/Piper_PA-31_Navajo
This happened less than a month a go in Hawaii: https://www.youtube.com/watch?time_c…&v=PRCPW5QDvjY

60% more efficient wind turbines as the currect HAWT propellers could be made according to this.

I actually checked again the g-force.
I have no idea why the wings didn’t explode.
I just want to inform all you that I was able clock the TSR of 10.1 with my small test turbine in 10 m/s wind. Wings sustained over 100 Gs….and seemed to have no problem doing so.
Wind could be a good source too..if someone wanted to take full advantage of it !
The only way humanity will progress is to use Nuclear followed by a complete farming of the energy from the sun.
So Nuclear is the only way until we can build a Dyson Sphere.
You may think this is extreme but it has already been demonstrated that you cannot build sufficient wind turbines to harness all our power needs, nor wave power.
There is also the law of diminishing returns. Wind turbine reliability and maintenance v cost v power. In other words when you have so many turbines the cost of maintenance will become prohibitive.
There is also the unsightly nature of them.
With the development of facilities that can recycle the waste from Nuclear power stations now coming online and the demonstrated reliability of new power stations I see that as the way forward.
Especially if we are serious about electric powered vehicles.
I partially agree.
H-Darreus/Giromill type wind turbines could be made long lasting and more efficient by many ways.
First electric generating wind turbine was made in Scotland in 1887 by James Blyth.
BTW: variable pith HAWT turned 100 years this year….invented by Vinding bros in Denmark.
Below also Aerogenerator-X displayed.
There is energy in wind ( dynamic soaring explained ):
Is the 61% efficient ANEW M-1 it ? This beats the propellors by 50% in efficiency.
Right Geoff….
I think it is time to move on to something more effective.
Best run at 60% efficiency. 50% better than the HAWT propellers.
