That form factor looks just about perfect for mounting on top of a 3' diameter irrigation impeller Here is a hydro electric dam generation hallway, which is basically the exact opposite irrigation pump  But yeah the wiki page says it was originally intended as a power generator

That reminds me, I went to see the new tunnel attraction at Niagara Falls last fall. It was one of the coolest drat things I have ever seen and I highly recommend it. The old 120 year old hydroelectric station on the Canadian side has been restored and opened to the public for a few years now, looks similar to above. They just recently made the wheelpit and tunnel below it accessible to the public. The power station is at the top of the falls, you travel down a glass elevator 180 feet and then walk down a 2200 foot brick and stone lined tunnel that exits out to a viewing platform in the gorge. The elevator ride takes you past 180 feet of dimly lit rusty machinery and catwalks. It’s like they drained the Titanic’s engine room and take you on a ride through it. https://m.youtube.com/watch?v=ZDndXge4IpE&pp=ygUOTmlhZ2FyYSB0dW5uZWw%3D

Is there a situation where using a gigantic radial engine like that for power generation makes more sense than a small gas turbine, or is it just that small gas turbines hadn't been invented yet?

I'm waiting for them to restore the other power station just upstream a little bit. https://en.wikipedia.org/wiki/Toronto_Power_Generating_Station I've been to the Sir Adam Beck station "tour" was kinda disappointed. My highschool electricity class got a pretty good tour of the Robert Moses plant across the river though. The nerdy physics teacher borrowed his son's Nissan Micra with a pretty bangin' system in it and drove us over the river. Back when you didn't need apassport to cross the border.

I think most of these are diesel generators. Diesel is easy to source, easy to transport by ship, easy to pump to shore, and easy to store. (guessing) Probably half or more of all island power in the pacific was diesel powered up until ~2010 when solar became affordable/reliable. The Philippines is going pretty hard on solar too It's also good to have multiple fuel sources because reasons, diesel is expensive but about as reliable as it gets edit: I guess it's also good for "black start" capability where the whole grid is down and you need lights to get your turbine generator (back) online more edit: https://www.ryanwilks.com.au/wp-content/uploads/2010/02/Colongra.pdf quote:Under normal conditions, the gas turbines at Colongra Hadlock fucked around with this message at 21:53 on Aug 4, 2023 |

Gas turbines probably weren't 24/7 reliable in 1947, and maybe efficiency? Looks like a modern 1200 kW [electrical output] turbine drinks about 160 gallons of fuel per hour https://global.kawasaki.com/en/energy/equipment/gas_turbines/emergency.html vs (this random post that says) the 11 cyl Nordberg made 1655 hp at 65 gph https://www.smokstak.com/forum/threads/norberg-11-cylinder-radial-diesel-engine.108045/

1655 hp is almost exactly 1234kw which would make it more fuel efficient than the turbine(?) Turbines probably have dramatically longer service intervals though

I was absolutely sure that combustion turbines in power generation were a post-WWII innovation, but godamn if the Swiss didn’t run the first one in 1939. The thing was installed and became operational as a standby generator in 1940, and was in-service until 2002.

1.2MW is pretty small for a power generating gas turbine, no? My understanding is that they get more efficient with size and Siemens for example makes 450 MW combined cycle turbines with 60% efficiency: https://www.siemens-energy.com/global/en/offerings/power-generation/gas-turbines/sgt5-8000h.html

For comparison, the largest diesel engine Wartsila Sulzer RTA96-C produces 80MW and runs at 50+% efficiency. A similar power turbine is probably more efficient, but not dramatically and the diesel engine compensates by being able to use the lowest quality bunker fuel.

It is the https://en.m.wikipedia.org/wiki/McMurtry_Sp%C3%A9irling fan car It's electric, and the turbine sound you hear is the suction fan that pulls it down to the ground with two tons of downforce, allowing it to accelerate 0 to 60 in 1.5 seconds and also theoretically drive upside down.

I’ve always wondered how fan cars deal with not even US roads, but just the race tracks themselves, there’s all sorts of bits of sand and small gravel, rubber chunks and just whatever crud blows onto the track from the surrounding area. Yeah they’re generally cleaner than public roads but I still think it must be hard on a fan system to essentially vacuum the road as it drives.

As I watched that video I was thinking "is that a fan car? It must be a fan car, it moves like a drat slot racer" and just then a huge cloud of dust and crud blew up behind it as it rolled over one of those dirty patches.

Fornax Disaster posted:I’m guessing built out of an old rv. Yeah. It's got too much meat on the back of the cab to be an old boxtruck. I had that idea the last time I needed to buy a truck. Older (2000-2010) box trucks ain't worth poo poo compared to a pickup, especially in 1-ton form (which almost all box trucks are now). The local door and box repair place said they'd take the box off and install/wire a pickup bed with 7-round harness for $1500 if I gave them a decent 16-20ft box. They had utility beds with a cutout for a fifthwheel for $750, which I figured could be turned into a 1/2 utility bed, 1/2 stake-side bed with some welded-on brackets. All up, I figured around $6000 for a Chevy/GMC 1 ton dually with the 6.0L. That would have given me a multi-purpose 1 ton for 1/2 ton Florida prices. Tow 10,000lb. at highway speeds, no longer than a short bed crewcab pickup for maneuverability, and enough room for tools in the utility bed to keep the cab free for everything else I carry around. You lose some mod-cons, and it would leak a lot, but it would do everything asked of it. Ran out of time when my raggedy-rear end $2000 Ram 1500 developed so many problems I got stuck towing a 20ft trailer on back roads through Tampa Bay with only 2nd, 2nd *, 3rd, and a horrible knocking sound from the top end. It's still an idea though, and not much worse on fuel than the nearly identical Ram 1500 (in way better shape) that I replaced the blue truck with.

Several podcasts and interviews have talked about how the McMurty needs to run in the middle of the Goodwood hillclimb track because it's a driveway with grading and the center is the only place the side skirts seal good enough to the track. It's purely a track toy for the ultra rich and while you could run on the road spewing rocks and debris at anyone tailgating it wouldn't make an effective seal so you couldn't ignore physics.

Went to the South Gloucestershire Show today and there a few classic cars on display. A few lovely jags  Some old american rubbish ('66 fastback according to the plate)  And this old Defender Lightweight, previously owned by the royal marines.  Still with the original radio equipment in the back  Info and for sale ad on the windscreen There was some other stuff including a bunch of RS owners club Fords but i didn't take pics of everything.

I was hanging out with tractors today. Saw this interesting doodlebug tractor (old car or truck reused by converting it into a tractor).   I think this was a 1928 Chevrolet. The engine is an early overhead valve four. This one looks like used a conversion kit rather than being completely home built. Typically how these worked is the diff was flipped upside down and small gears attached to the axles driving big ring gears in the wheels, to give it a super low gear ratio. This is another example of frugal farm reuse I thought was neat -  Reuse old tires off the family car on the seeder. When was the last time wide whitewall snow tires were made? Brand is Seiberling Commuter, internet search turns up some 1950s newspaper ads.

I thought that the last time that someone tried a fan car, it was banned in no small part due to it blasting the other cars with rubble that it picked up from the track. That seems like an insurmountable problem for a fan car.
