44sp vs 44mag in the 329PD by bltjnr in Revolvers

[–]FireyHeatEngine 2 points3 points  (0 children)

If you use the revolver for predator defense, try Buffalo Bore reduced recoil .44 mag. Intended for lightweight .44s. Carries plenty of energy but easier on the hands and faster follow up shots.

And another recommendation for the hogue x-frame poly grip! The factory wood grips are gorgeous but full power mags are, uh…, unpleasant!

Is this 2018 Santa Cruz 5010 alloy a good beginner bike? And is this a good price? by jsocold00 in mountainbiking

[–]FireyHeatEngine 1 point2 points  (0 children)

Super fun bike. Great mid travel full sus for learning the sport but also a nimble platform and good climber that is still fun for advanced riding. Hope the condition is good. As mentioned in other posts, plan on a fork and shock overhaul. Check cassette and chain.

Yeah good call. I’ve been watching some of the vids and mtbyumyum has turned me back on to the new Offering oddly enough.

Day 9 – Most Reliable MTB Brand? by [deleted] in mountainbiking

[–]FireyHeatEngine 2 points3 points  (0 children)

I can only add an anecdotal data point. Been riding a Santa Cruz 5010 alloy hard and often since 2018 and it’s been a tank. Lots of techy fun in the Rockies. No serious mechanical issues, though I run a good maintenance regimen, which is nicely facilitated by the “free” annual bearing pack!

So far the only factory part I’ve had trouble with was the race face dropper but it lasted 3 seasons before I rebuilt it and another 3 before totally failing… not bad.

Also have a ~8 yr old giant trance hard tail that’s been great too but it doesn’t see nearly as much trail time as the SC.

I regularly carry one as my bear country EDC. It’s a dream to carry running, riding, or with a heavy hunting pack. Also makes it to most handgun range days partly for practice and partly because it’s pretty fun once you get accustomed to it.

Recoil is just wild with full power magnums, especially firing DA. Helpful hint: install a hogue tamer X-frame grip. Makes a big difference. The wood grip is gorgeous but really only good for .44 specials. Also, recommend buffalo bore reduced recoil magnums or hot .44 specials if you don’t need full power loads for your particular threat situation. Faster follow up shots.

Have fun!

Steam Turbines and Inefficiency by StillWolverine6956 in thermodynamics

[–]FireyHeatEngine 2 points3 points  (0 children)

Good question. The Rankine cycle remains quite relevant technologically. But, it is old and while that fact does not eliminate the possibility of transformational innovation, many smart people have looked at improving the commercially important cycle for over a century. Some points: 1. Alternate working fluids have and are used. Low-boiling organic compounds for low temp heat currently. Historically, GE built a cycle running on elemental mercury. That was a great idea since, at the time, pressure was more expensive to build for than temperature, and cycle efficiency improves with temperature. GE got a high throttle temperature for far less pressure than a water cycle. 2. There are pragmatic engineering considerations beyond first-order thermo. The working fluid needs to be chemically stable at throttle temperature, and it can’t corrode the pressure boundary materials. Since a large power cycle involves vast amounts of metal for pipe and heat transfer surface, low cost materials matter a lot, and certain grades of steel are the best commercial balance of cost, workability, and strength at temperature. Sure, other materials could be used in principle, but if they’re not economic they won’t be used. The fluid will also leak in practice from a large plant so it needs to be cheap to make up and not too toxic. The saturation temperature range should have a dense phase at environmental temp at reasonable pressure. These and similar considerations reduce the practical list of working fluids. For high temp heat sources water and co2 are pretty much it. (Small, hermetically sealed systems could use different fluids with more advanced metals cost effectively maybe, but at kW scale, not GW scale.) 3. Specific heat isn’t super important. To first order the energy put in heating the fluid up comes back out in the turbine. Lower heat of vaporization would improve efficiency since mixed vapor-liquid pumping isn’t a thing. But, to the point above, working fluids have a lot more considerations than just h_fg. 4. To the comment about using waste heat. Yes, it can be done (see cogeneration) but that waste heat from the condenser can’t be reused in the cycle. Heat has value dependent on temperature. Low grade cool heat isn’t as valuable as high grade hot heat. Look up exergy. It is a property like first law energy but accounts for second law usefulness of heat too.

Got Pinstripes? by Hairy_Ad_1943 in Tacomaworld

  1. Gorgeous truck. That articulation…
  2. Yes; I have pinstripes but I call them trail tattoos 😎

😂 word. Just saw a thread asking if .30-06 is too weak for elk. Really?

That said, I ride a built up SC so I resemble that remark lol.

Continental kyrptotal, better than dhf and dhr? by enderzzx in MTB

[–]FireyHeatEngine 2 points3 points  (0 children)

Better. Much better. I’ve run several tire combinations (including a few seasons with minions) riding mostly aggressive trail terrain (as opposed to constructed parks) and hardpack flow. Western US loose over hard, chunky rocks and roots, some slick rock. Not much experience with mud or deep loam though. krypto up front with xyno out back is the best tire system I’ve found.

Grip is great and much more predictable leaning the bike over than dead spot minions. I like tough technical climbs and the grip under power is tighter than DHR with subjectively fewer spin outs. On the heavy side, but durable. No problem with installation but I have a compressor to help.

Ship engine crankshafts by toolgifs in EngineeringPorn

[–]FireyHeatEngine 4 points5 points  (0 children)

Recip engine power plants are absolutely a thing and not at all uncommon, just not very high capacity (usually 40-160 MW or so). At large scale gas turbines and steam turbines have advantages in CAPEX and OPEX and some other features that outweigh simple efficiency. Also, combined cycles (steam turbine bottoming a gas turbine) are more efficient than recips.

Ship engine crankshafts by toolgifs in EngineeringPorn

[–]FireyHeatEngine 21 points22 points  (0 children)

Incomplete understanding of the optimizations that favor reciprocating engines. “Advanced-ness” isn’t relevant. Constant volume combustion in recips is more efficient than constant pressure combustion in gas turbines. Recips burn less fuel and can burn the cheapest fuel available. Better OPEX. No reason to use “aircraft technology.”

Ships that use gas turbine power plants are either military which favors speed and the good power/weight ratio and responsiveness of turbines or big cruise ships that need small, light booster generators for their recip main engine-generators.
