It will be a small low floor step van the size of a KubVan or a little larger than the LLV.

Delivery McGee posted:Apparently they use J57s in backup gensets for exactly the opposite reason, amusingly -- diesel gensets take a good ten minutes to warm up before you can load them, a jet is at 90-something % throttle and ready for more the instant it fires. (Source: that jet mechanic on youtube, I forget which video.) I've worked in plenty of places with diesel gensets, if they're in good shape they're generally online in less than 15 seconds (this is assuming a reasonably large 3 phase unit). If they have to crank a few times, maybe 30-45 seconds. And that's if you've really neglected them; even ancient ones are supposed to self-test (which causes them to start up and run for at least 5-10 minutes) a few times a month. Yeah, running up to full speed immediately after starting isn't GOOD for an engine, but it's the norm for a generator. And let's face it, how much use is a backup generator going to see outside of built-in testing? In an area with decent power, it might be needed a couple of times a year, and usually for maybe an hour or three at a time. I know drat well that the last grocery store I worked in never did anything related to maintenance on their Kohler set (roof mount), and it always had the most basic lights on (plus the automatic doors working, exit signs lit up, and very basic refrigeration going) within 15 seconds. It would run for a few minutes after the power came back on to cool off, I assume. The control panel was tucked away in a corner, with a constant beeping coming from it, but management didn't care enough to bother maintaining it (plus, well, the whole "it's on the drat roof" part). randomidiot fucked around with this message at 11:30 on Nov 26, 2015 |

The gensets for our data center (we have two, both able to handle about 2x the max load the data center can draw, plus the emergency stuff for the rest of the building) go from off & cold to 100% output in about 15 seconds, or so I'm told. The UPS systems in the data center can run the data center at full output for about 18 minutes. In the 5 years I've been at this building, I'm only aware of 3 times they've come on outside of testing, and one of those was when some idiot crashed into a pole and the power companies systems failed to reset and re-route the power properly after the circuit breakers tripped from the downed lines. Also, I always knew we had a lot of fiber coming into the building, but I found out a while back that each client actually brings their own redundant fiber into the building, in addition to our own main company redundant fiber links for our internal networks, and connections upstream to our vendors. So apparently we have over 140 (or more) separate fiber connections into the building from each side (physically redundant links so that a cut theoretically doesn't take out anything). Would suck a lot to be a contractor that dug across our parking lot and took out one of those sets of conduits.

Ultimately you're taking an engine that is designed to be run for tens of thousands of hours and running it for maybe a thousand over it's lifetime. I doubt the extra wear matters.

Yeah, we've got six 2MW diesel generators at work. They're ready for full load in about 15 seconds from a "cold" start - not that it's ever truly cold in AZ, but they still have heaters to keep the coolant warmish even in the winter. They fire up quickly every time, though it's been extremely rare that we've ever needed them outside of maintenance and testing. Unlike the rooftop unit STR dealt with, though, these things get maintained on an extremely regular basis. They actually make it a competition to see who gets their generator the cleanest.

I would guess the reason the military uses J57 powered generators is they have an utter fuckton of the drat things and I seem to recall they like to use jet fuel to power everything because its simple from a logistics standpoint.

Personally have repaired a fuel pressure regulator on one of those with a bic pen spring. gently caress those generators.

That's a hell of a lot of fiber and bandwidth. Of course that building houses 110 companies/datacenters, whereas we are just a single small 2-story building and a single company (and not the giant HQ which is back east). With the UPS's and gen-sets, it really doesn't make economical sense for our company to pay for that sort of a power feed either, given that the power here is extremely reliable, and everything we have in our data center is also fully mirrored at the HQ (all of our stuff is hot/hot on both coasts, and hot/hot redundant within each data center as well), with a third 'disaster recovery' data center in another state that is on warm backup. Also, I have no idea what this has to do with terrible car stuff anymore, I thought this was the general chat thread. Oops. Edit: Terrible car stuff - I saw a Honda Civic on the way home tonight (too dark to get a picture, even if I was silly enough to try that while driving down I-10) with the most amazing giant fender flares on the front. I think the entirety of the front tires were actually inside the flares, outside of the car's original fenders. It was.. something.

Frivolous lawsuits need to die already - deal with the fact your family member did something dumb and reckless and paid the price. Porsche didn't put a loving gun to his head, force him to mod his car, and tell him to break the law and crash. Then again, sounds like daddy cares more about money and attention than anything, says all people need to know about him really.

Maybe two months ago(?) when Paul's daughter filed suit, Matt Farah (of Drive / The Smoking Tire) had a few things to say on his podcast. It turns out the lawyer handling the suit had contacted him just after the accident trying to get him to be a witness saying Porsche was negligent. Which he declined, more than once. His impression was that this is a really tragic case of a lawyer exploiting a grieving family. Porsche didn't really do themselves any favors settling with family of the guys killed at Cal Club / Fontana.
