The biggest reasons were the precision and strength of materials allowed higher pressure steam. There are three sections in modern steam turbines, the steam goes through the high pressure section, then the medium and low before it's condensed and pumped back to the boiler. The lower the pressure the larger the blades.

EPRI(Electrical Power Research Institute) funded by all the power companies in the country, had a test turbine at PECO's Chester station running 5,000 psig steam(close to 1,000 deg F). Just to add a pressure tap or thermocouple was a major pain in the ass because the wall thickness of the pipe was over three inches of high strength steel. Drill the hole, then follow a strict procedure to weld in the tap with each layer of weld inspected. Lastly make sure there is NO chips or slag on the inside of the pipe to become missiles when restarted as they would wipe out blades at that speed.

I found this picture with no information. Obviously it's a manufacturing facility. Tin-eye couldn't find it. Google found it... on fucking pinterest. I just had time to grab the title before they shut me out. It said, "Elevator Flywheel".

They have a digitized old brochure that says it's a "turning flywheel in pit lathe."

And they found the original of the photo here. The flywheel was at Mesta Machine Co in Pittsburgh

Excellent, so we know who made it and when, just not what it's for.

Good find, da bof o yas.

Great find fellas, I appreciate the effort.

I'm putting this in machines rather than rims because I doubt it ever made the road, despite what the 1914 Mad Men claim, and the claims are whoppers.

The Airmobile used a “frictionless rotary engine fueled by crude oil” to power a “rotary air compressor” located behind it. Air pressure was stored in a pair of tanks and routed through a throttle to an air motor at each wheel. No one has uncovered photos or more information about this car other than an advertisement in the program for the Santa Monica Road Races and a few other places, the effort then disappeared into thin air…. By 1915 the Rotary Air Brake Company was promoting an air-steam-gas-water engine that is known to have been produced.
The company’s name was changed to the Rotary Products Company and in 1920 they began manufacturing air driven machinery for industry.

I think "frictionless" means I don't hear no squealing or scraping.

Shred a whole car, and I mean whole, tires, glass, interior, engine, in less than 3 minutes.

Presumably a cubic yard (or thereabouts) of compressed metal and other stuff comes out of the other end of the machine.
I'm just wondering how it's processed for re-manufacture given the volume of material that isn't steel.

well, it comes out in a stream of chunks/shreds/bits and the ferrous material can easily be sorted out magnetically. That's one stream. The rest, there are other sorting methods, air blowers, by density, etc, etc.

There are big blowers to separate the upholstery/foam, magnets to pick up the ferrous metal (some stainless is ferrous and some is not), but I'm not sure how they separate the plastic, copper, and aluminum because that's done offsite.
Goldfinger used a compactor, not a shredder.

Thank you, Gentlemen. All is clear now.
I was labouring under a misapprehension.

Eh, it happens.

This machine I've been up close and personal with several times. Custom built and flawless.
I haven't seen it with that pickup aboard which has a color I despise.

Is that Bianchi green or Tiffany blue?

I can only imagine how many sales Bianchi lost based on color alone.
