Horizontal Wind Turbine farms - management - Good Neighbor Policy

tahanson43206 · 2023-04-04 09:27:23

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.

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.

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.

Axis.diagram.horiz_.jpg

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.

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.

How Much Does a Home Wind Turbine Cost?

Highlights
The typical cost to install a home wind turbine ranges between $300 and $75,000.
Some of the factors that affect the total cost include the turbine’s type, size, and capacity; the wind speed requirements; the installation location; the cost of labor; ongoing maintenance costs; and available tax credits.
There are several benefits to installing a wind turbine at home, including decreased energy bills, increased home value, high efficiency, and clean energy.
Homeowners may be able to install a small wind turbine themselves; however, hiring a pro will result in a safe and compliant installation.
Harnessing wind energy for residential use has become increasingly popular as people seek cleaner and more sustainable power sources. But just how much does it cost to install wind turbines on residential properties? The typical cost range for a home wind turbine installation can vary significantly, ranging from as little as $300 to as much as $75,000.
The wide range is due to cost factors such as the size and type of turbine, wind speed requirements, installation location, and site preparation. Each of these can vary significantly from one property (or part of the country) to another. Homeowners interested in using renewable energy on their property can learn more about what goes into estimating a home wind turbine cost, the benefits that come along with having a clean energy source at home, and ways to save money on installation.
Factors in Calculating Home Wind Turbine Cost
Determining an accurate budget to install a wind turbine for home use will require homeowners to review several factors in addition to speaking with a professional installation company. For example, turbine size, installation location, and ongoing maintenance fees can all influence installation and operating costs. While national average costs can serve as a useful benchmark, understanding local variations for labor and material costs can also help a homeowner properly budget for a wind turbine.
Turbine Type, Size, and Capacity
Turbine type, size, and capacity play important roles in determining both the effectiveness and cost of wind energy systems. There are two main types of wind turbines for homes: roof-mounted and freestanding. Roof-mounted designs are the most cost-effective option, whereas freestanding options are the more expensive choice. However, the latter can generate greater amounts of electricity than a roof-mounted design.
The size of a wind turbine refers to blade length and tower height. A larger turbine will likely have higher up-front material and installation costs than a small wind turbine. Similarly, the capacity of a turbine, or the maximum amount of electricity the unit can generate under ideal conditions, influences pricing. Homeowners can expect to pay more for higher-capacity turbines.
Wind Speed Requirements
The wind speed requirements for a home turbine correlates to the unit’s effectiveness, type of unit needed, and overall costs. Wind speed directly influences how much energy a turbine can generate and, in turn, how much potential return on investment a homeowner can expect. Homeowners can calculate their capacity factor (the measure of a turbine’s efficiency) with this basic formula:
Capacity factor = (average wind speed) / (rated wind speed)
If the average wind speed is 6 meters per second (m/s), and the small wind turbine has a rated wind speed of 30 m/s, then the capacity factor would be 0.2 or 20 percent.
Capacity factor = (6 m/s) / (30 m/s) = 0.20
In this example, the turbine could generate electricity at 20 percent of its capacity, on average, which is more than the 17 percent average capacity as noted in the 2018 report by the U.S. Department of Energy.
Homeowners can then calculate the number of kilowatt (kW) hours that can be produced by a small wind turbine if the wind blows frequently.
Kilowatt hours per year = (number of hours in a year) x (unit’s power rating) x (capacity factor)
A typical home in a windy area needs a 10 or 15 kW turbine to provide sufficient power. This number can be multiplied by the number of hours in a year and the capacity factor.
8,760 x 15 x 0.20 = 26,280 kW hours per year
Understanding the rated wind speed and how it affects the capacity factor helps homeowners assess the suitability of a wind turbine for their location. If the average wind speed in an area is significantly lower than a turbine’s rated wind speed, then the turbine may not operate efficiently, resulting in lower energy production and potentially a poor return on investment. The American Wind Energy Association (AWEA) notes that homeowners usually pay an installation cost of $2,000 to $5,000 per kilowatt of the unit’s power capacity. This means it could cost between $30,000 and $75,000 to install a 15 kW wind turbine.
Generally speaking, turbines with higher-rated wind speeds may cost more to install due to their enhanced performance capabilities and advanced technology. However, they could also generate more energy and be more efficient in the long run.

Not only is the energy a benefit but there are also taxs credits as well... long article.

Friends of Airloom!
As we head into the holidays and close out 2024 we here at Airloom wish each of you a joyous and restful holiday season. It’s been quite a year for us, to say the least! Here are a few accomplishments we’re most proud of:
Closed Seed2 funding (thank you investors!)
Welcomed 7 new teammates
Built a strong team of (~30) contracted engineers
Won a direct Phase II SBIR ($1.25M)
Awarded EMF Funding ($5M)
Completed a loads analysis that enables system modeling & simulation
Developed design tools built from detailed trade analysis across aero, mechanical, electrical, and controls
Completed Phase I and Phase II Loomcamp where we welcomed input and critique from some of the world’s foremost experts in energy and systems engineering
Established strategic partnerships with key DoD allies, future commercial customers, and potential industry partners
Built relationships with potential Series A investors
Leased land in southeast Wyoming for our 2025 pilot
As we look ahead to 2025, here are a few things you should expect:
Jan: Concept Design Review (CoDR)
Feb: Met towers installed to measure wind; belt and power take-off testing begins
March: Site construction begins
August: Critical Design Review (CDR)
October: Airloom turbine installed. Testing begins.
Nov/Dec: initial test results
Airloom's CTO Andrew Streett presenting at Loomcamp Phase II
mark-1
Technical Progress
Product Technology:
Concept Design Review (CoDR) is scheduled for January 22-23, 2025. This review will deep dive into subsystems concept designs to ensure that business needs are being met with “durable designs,” meaning they stand up to questions and other concepts proposed. This review will lock in the design baseline that will be further detailed, fabricated and ultimately built.
Dedicated Test Articles: The highest technical risks have been assessed and the Power Take Off (PTO), belt transfer of power, fatigue in these components, and the electrical performance are all tests that can be run before PDR to provide objective feedback to the team before final designs are completed. The team has scouted a location to house these tests and is in the process of completing the designs and ordering long lead items like generators, power electronics, controls electronics, and belts.
Verification of Simulation: Airloom’s simulation is home-grown and this phase shall validate that simulation. However that process doesn’t start after the Airloom System is on-site - it starts at the beginning. For the last 6 months the team has been working to verify wind models, turbulence modeling, force generation, and system efficiencies in an effort to steer the Airloom design to CoDR. We have been successful verifying the simulation against industry standard tools like NREL’s openFAST and Sandia’s OWENS. There are more verification steps but at this stage the verification work is progressing nicely to enter CoDR and will enter higher fidelity simulation in Simulink for presentation at PDR.

Project Delivery:
Leases Signed: Three separate leases signed in Albany, Carbon and Laramie counties. An additional four leases are in negotiation.
MET towers: Equipment has been purchased on a 4-6 week delivery timeline.
Permit Applications: With sites identified we are beginning the permit applications for the MET towers and then the site itself. We have already met with all three counties so have a good idea of what is required.

Team
We welcomed a new teammate, Phillip Gregory who joins Airloom to lead site development. He’ll be based in Laramie. Phillip brings 20+ years of wind industry experience including time at Clearway Energy, NRG Energy, and Mitsubishi Power Systems America.
We’ve opened a role for a Senior Mechanical Engineer.
Commercial Update
We made it through the initial screening for the Earthshot Prize. Not sure how many more rounds there are, but are encouraged by making it this far.
Invested additional time and focus to expand our collaboration with the National Renewable Energy Lab's (NREL's) National Wind Technology Center. We’ve been working on two projects with them: 1) a Techno-Economic Analysis and 2) modeling Airloom loads with their tool, OpenFAST. We visited their campus again in December and may open a few additional lines of effort.
We have pulled together the partners and resources to submit a TACFI package. We haven’t fully decided to pursue it and it’s worth noting that our USAF partners need to be fully bought in and supportive, and they are not yet (we think they’ll get there!).
We have decided to pursue a Defense Innovation Unit (DIU) funding opportunity called “Finance First.” We’ll submit this with one of our development partners (a big US developer).
Challenges
Aero Drag: We have updated the traveler and wing design such that the aero drag is substantially lower (nearly 50% lower). This took a redesign of the wheels, track, and support structure. We are in early concept design so we are going to find additional reductions as the design matures.
Schedule: Priorities required that long lead and early designs of the dedicated test articles be prioritized over the concept designs for
subsystems like the wing pitch system. This is necessary to get data from the dedicated test articles before PDR so that lessons learned can be incorporated. With those designs firming up, we’re now shifting our focus to finishing wing pitch subsystem concept decisions around low cost, system robustness, and meeting the angle of attack (AoA) tolerances.
Upcoming Priorities
Prepare for the Concept Design Review (CoDR)
Install MET towers at the top 3 pilot sites
Finalizing the site delivery schedule
As we wrap up a remarkable year, we want to express our deepest gratitude for your interest in who we are and what we're building.
This year has been full of progress, milestones, and momentum—none of which would be possible without the hard work of our team, the enthusiasm of our partners, and the encouragement of our entire community.
From all of us at Airloom Energy, we wish you a joyful holiday season and a new year filled with health, happiness, and success. Here’s to even greater achievements in the year ahead!
Looking fwd,
The Airloom Team
The next era of wind power
