They seem interesting for a grid tie system to have some electricity if the whole neighborhood is out. It would be cool to get some perspectives from owners and average output depending on rating and wind speeds.

A Friend Had Website years ago THis Article may help:

https://watchman2012.wordpress.com/2012/04/25/alternative-energy-how-to-calculate-the-output-of-a-diy-alternator/

there were plenty of build it yourself sites, but none could accurately predict what the output would be. after this went live, the diy sites all had a section, that modified the variable names (to pretend they came up with the "science" on their own LOL)

literally first of it's kind article had traffic from China Russia and Africa that month and found links to it in dozens of universities LOL

for a SHTF scenario, an alternator attached to a wood fired small steam engine is the ultimate yesteryear solution, and scales well from household to industrial... they melted all/most of the steam engines in WWII, so having a machinist in your pocket will help

Haha. Sounds like a pain in the ass without a controller or voltimeter. I kinda want to get a CNC machine for small parts, but bending sheets is a much bigger pain in the ass. You need to develop a whole process with makeshift tools. There are some barrel generators I've seen on YouTube. They cut the barrel in half and attach it to the axis rod and the wind gets caught in the hollow parts and spins it. It's not very efficient.

Small turbines dont really generate much energy. Hell the big ones are kinda useless too. Windmills in the past were used for mechanical action like grinding wheat into flour

What do you want to use this for? Supplemental power or emergency power? If it is emergency power for your whole neighborhood, your best bet is to get the entire neighborhood to fund a SBO generator, CAT makes some completely enclosed packaged units up to around 4MW which are diesel driven and perfect, if not oversized for a neighborhood during an emergency.

If you are looking for supplemental power you need to research the number of windy days/durations and speeds of the wind. ASHRAE codes may have this info, but your best bet is to get this information from your nearest federal weather station, every airport has one. You can find it online.

Unless you are in a place like Oklahoma where it is seemingly constantly windy It may be a better option to go with solar panels. Like wind turbines, solar panels are heavily dependent on the weather, which is already unreliable. They will never make their rated power. Say a wind turbine is rated for 3MW, it wont produce 3MWh all the time, or even when operating. Its based on the strength of the wind, and the duration, its rated power is always higher than its operational power. IE: 3MW rated, produces 2MWh for 6 hours a day from wind/sun. Not ideal in emergency situations.

It is unlikely that there ANY private / individual windmill owners, certainly that participate here. Windmills / wind farms are an investment for market touts only.

Do you know any ‘Ma and Pa Kettle’ types that brag on their new Cadillac bought with the savings ‘ profit from their windmill?

I don't mean like the building sized ones. lol

There are small turbines you can carry in your hands that can mount to your house.

If you want something to mount on your house you might as well use solar, about the same cost and production but less vibrations and it'll last longer.

Panels aren't modular enough when mounted to the roof and are more likely to damage it. Solar also doesn't work when there's no sunlight. Vibrations don't seem to affect the turbines as much since the base would need to be most affected, which doesn't happen quite as much compared to the whole house taking some damage.

Small turbine, small power. How much power does a toaster require? Convert that to wind energy. I am an engineer retired.

Based and logistics pilled. Having spent time living in a third world country with only a 2kW camping generator for power supply, it is amazing how much electricity toasters, coffee makers, microwaves, etc require. Anything that has heating coils really.

I find it fascinating that our modern society just takes all of these things, ie. like how electricity is generated, for granted

I ran, tested and fixed small 100 MWe nuclear power plants for twenty years.

Was that a test reactor? or SMR? A 100MW unit is tiny.

Battery storage first. You'll have power in the short term, and is perfect for rolling blackouts. This makes the base for any other electric generation method you like.
