Horizontal Wind Turbine farms - management - Good Neighbor Policy

In a nearby topic, Louis introduced the concept of vertical turbines.

This topic is offered for discussion of horizontal wind turbines, which appear to be the most common form in 2023.

The first post in this topic is a report on a Good Neighbor policy in Kansas.  The aircraft warning lights are a source of irritation to neighbors of wind farms in Kansas, and the article reports on a plan to turn on the warning lights when aircraft are nearby, and to keep them off otherwise. Since aircraft are very rare in the areas where wind farms are established, this seems (to me at least) like a sensible policy.

The cost of a radar installation is about 1/3 of the cost of a single wind turbine, and the radar can serve an entire farm.  The farm owner should see a return on investment due to reduced burnout of red lights and other factors related to the warning system.

Sen. Mike Thompson, R-Shawnee, said a radar system is about $1.5 million, and one should be enough for most developments. That's less than the approximate $5 million cost to build a single turbine, he said.

"This is really cutting-edge legislation that will probably go into other states," said Sen. Rob Olson, R-Olathe.

Lights atop wind turbines affect sleep and traffic, Kansas legislator says

HOUMA, La. (AP) — In Louisiana bayou country, where oil rig supply ships are as much a part of the waterside scenery as shrimp boats, a new kind of seagoing behemoth is taking shape that marks offshore wind power's growing presence in the energy seascape.

Louisiana shipbuilding giant Edison Chouest Offshore is assembling the 260-foot-long Eco Edison in coastal Terrebonne Parish, along the Houma Navigation Canal. It's being built for Ørsted, a Danish firm that builds and operates wind farms worldwide, and Eversource, a New England energy provider. When delivered next year, the ship will serve as floating housing for U.S. offshore wind technicians and a warehouse for their tools as they run and maintain wind farms in the Northeast.

I expect that offshore wind turbines will have red warning lights running 24*7, because aircraft can fly over the ocean without restriction.

However, wind farms that are visible from shore may irritate the folks on land, so the aircraft detection radar systems may be needed in those locations.

Re: Horizontal Wind Turbine farms - management - Good Neighbor Policy

This is an example of a really simple and easy to build, tilted horizontal axis turbine.
https://en.m.wikipedia.org/wiki/Tjasker

This design is native to the Netherlands and it is used exclusively as a low head drainage pump using a direct-drive archemedes screw.  It is not particularly efficient, because the sails are so close to the ground.  But it is easy to make from wood and uses simple friction bearings.  In the Netherlands, the winds are predominantly westerly.  So a turbine facing west will intercept the majority of wind energy without any need to turn into the wind.

Although slightly less efficient than horizontal axis, vertical axis turbines like the Savonis have the advantages of being easy to make from common materials like wood and old barrels, able to exploit wind from any direction, and they provide more torque at low wind speeds.  These are machines that literally anyone can build out of junk.  The high torque is advantageous if you want a machine that can provide direct mechanical power to a workshop driven by a line shaft.
https://en.m.wikipedia.org/wiki/Line_shaft

If large parts of the world end up deindustrialising, these are the sort of simple technologies that we could build locally on a shoe string budget.

Very simple machines like the Tjasker could provide goods transportation by pushing low head water into a pipe or canal.  Trains of capsules or coupled barges could be carried by the flow at roughly human walking speed.  If the world were to run out of diesel tomorrow, we could use a system like this to maintain goods transportation.  At an average speed of 4mph, we could transport freight from coast to coast in the US in about a month, using simple wind machines to pump floating capsules along a tube or ditch.  In the UK, which is much smaller and has more wind, such a system could work even better.  If we needed to build a low cost goods transportation system on a shoe string with only the most basic resources, then this is something we could use.  Large parts of the world are facing post-industrial collapse over the next several decades.  The world is going to become disconnected and many resources will not be available to most people in most places.  Having simple technologies that can work using local resources, will be an important way of sustaining civilisation.

Re: Horizontal Wind Turbine farms - management - Good Neighbor Policy

A horizontal wind turbine is classified as horizontal because the axis of the rotating turbine is horizontal, or parallel to the ground. They are the most efficient available wind turbine in today’s market. But, the biggest disadvantage of the HAWT is that it needs to be facing the wind in order to operate efficiently.

You see them in lots of places, and these are large and usually complained about when it comes to not being very esthetic in particular along mountain ridges.

The main issue is the blade count, surface area and sweep of them all relate to the collecting energy that they can receive. Wind speed is also a crucial factor when deciding the power class wind turbine.

Re: Horizontal Wind Turbine farms - management - Good Neighbor Policy

NewMars appears to have landed on the Airloom mailing list.  There are so many topics with "wind" in the title, I'm picking this one because the movement of the wings is horizontal.

Happy 2024 from Airloom Energy!

In reflecting on the past year, we found so much to celebrate. We welcomed amazing new members to our team; strengthened existing partnerships and formed valuable new ones; and were gratified by the tremendous outpouring of interest in our work.

We’ve shared links below to a few highlights from the year in review. Thank you for all your support, and we look forward to sharing new milestones and adventures with you throughout the coming year.
