You see, this is the funny bit. If you wanted to make it representative of the general population, you'd need to hire about 5,000 MORE whites and fire about 8,000 asians. But of course, facts are wildly unpopular when people just want to play identity politics and hate on the majority.
The question is: will Samsung integrate those pearls? Or would this Solaris platform be shelved?
Shelving the Illumos core of SmartOS (Joyent's cloud OS platform) would essentially completely destroy all value in Joyent. Its distinctive cloud technology is intimately tied to Zones.
He does the U.S. mail run to McCartney
Just to clarify, your father, holder of a private pilot certificate, is employed or works for hire (i.e. receives compensation) to fly mail? If so, then that would seem to be a direct violation of 14 CFR 61.113. Are you sure he isn't a holder of a CPL?
If you want to go full-retard, why don't we talk about the amount of energy we can get from nuclear reactions of Lithium atoms versus carbon atoms? It's just as relevant as this spewing crap.
Gee I hope you're not doing nuclear reactions in your fuel cell.
Compared to advanced piston engine airliners of the 1950s, current jet airliners are only marginally more efficient per passenger-mile.
Yes. But the pistons were also a lot slower, noisier, less comfortable and less reliable, all of which are rather important details to airlines.
At lower-speeds, props are much more efficient than turbofans, and props can of course be easily driven by electric motors.
And you know what's most efficient? Not going anywhere. If there's a flight that takes 4 hours and another that takes 8 hours, I'll strongly consider the 4 hour one, even if it costs more. Moreover, the airline sees it like this: how many passenger-miles can I do with this type per year? That equates directly to profit. Slower airplane = fewer seats sold per year = lower profit margin. Even if your shiny new airplane is twice as efficient, if it's half as slow, you've not actually gained anything. Why do you think airlines buy jets for anything above regional?
At lower-speeds, props are much more efficient than turbofans, and props can of course be easily driven by electric motors.
You can also drive a fan using an electric motor just as well.
And electrically-driven aircraft is incredibly simplified, to the point that airlines would want them for their lower maintenance costs and less downtime, even if the efficiency wasn't substantially better
Well, maybe. It depends on the details. For one thing, the FAA won't let you get away with just one fuel cell system. You're gonna need two independent ones, or else you won't be allowed to put any passengers on it. It's unclear if it's gonna be simpler, require less maintenance or be more reliable, as no such aircraft are even on the serious drawing board (I don't mean concepts, I mean actual detailed designs for flight worthy hardware).
You're forgetting how inefficient turbofan engines are at part-throttle conditions.
Proportions matter here. Turbine engines run in cruise at around 95% of rated RPM and about 3/4 to 4/5 of maximum thrust. In those regions, they are pretty much at the efficiency plateau. Those things aren't designed by idiots.
As for idling, yeah, they're inefficient. Everybody knows this, which is why partial-engine taxis are common nowadays and even so the overhead isn't so bad. I just did a quick calculation with my dispatch tool and a 737-800 on a relatively short hop of ~1.5 hours (only about 1 hour actual air time). A 20 minute taxi-out and 8-minute taxi-in (all engines running) comes to only about 9% of the trip fuel (6000 lbs trip, 500 lbs taxi). Would airlines be happy to reduce it? Definitely. But is it some huge environmental saving? Not really. And keep in mind, this is short-haul, so about as high as it gets. On longer routes the taxi falls quite dramatically. On a transatlantic route it's only about 2% of the trip fuel and transatlantic is quite short by long-haul standards (only ~6 hrs flight time).
After the last of 16 mounting screws has been removed from an access cover, it will be discovered that the wrong access cover has been removed.
