But they’re at least much larger and better built - all the “new” containers you can buy in the use are built as one trip containers in China - sure they seem in good condition, but their longevity is suspect.

You make it sound like container housing was a fad. Container housing is on the rise.

Haha!

I’m a big fan of big fans too!

By the time one of these housings is getting phased out, the turbine design is years or decades out of date. The internal components are all going to be different. The exterior of the housing is also part of the airflow design.

Considering the amount of torque being applied to the components in the housing by the rotor, it probably wouldn't be safe to drill new mounting holes in an old housing to fit a new generator &etc.

Nice 360° view though.

Four metres wide, 10 metres long and three metres high,

this one is larger (by about 25%, and excluding the also higher ceiling) than my walk-up apartment.

I'd rather have had that when I was living out of my car.

There seems to be a big market for tiny homes among older single people especially women. Like containers, there should be no problem in linking a couple or pods to create a bigger space.

An interesting guest house if nothing else though if want to set up plumbing

Perfect for housing the homeless. Better than no home.

Fiberglassmping?

I lived semi-comfortably for over a year in a 29m² apartament with my spouse and our small child. I see no reason why 40m² couldn't be a permanent solution for singles and child-free couples. Depending on structural durability (can they be stacked? Maybe if we add a steel frame?) we could build apartament complexes which would further extend the user pool. You don't need a lot of space inside the house if you have a well stocked library and community workshop around the corner. Add some playgrounds and you can house young families. Heck, join two modules together and you got space enough for a 2+2 family for a lifetime.

The only real problems I see is we don't know the energy efficiency of the unit and how the cost compares to traditional building methods. If it isn't much cheaper the downsides (fixed size, lack of steady supply etc.) will kill it.

fiberglass insulation works because of 2 things, glass' low thermal conductivity, but especially because all the air trapped between all the thin strands. Shredding these would create a mainly compact granulate/dust, and a shit ton of microplastics.
