<whitequark> azonenberg: you need 5kw of thermal power? how about building a vapor compression refrigeration system?
<whitequark> if I do in fact reach the US and you have about three spare days and could give me a ride to the nearest HVAC shop...
<whitequark> the car HVAC system seems unlikely to be able to handle additional 5kw of load simply because it's so space-constrained

<azonenberg> Lol well i dont plan to ever actually put that much in a car
<azonenberg> it was rqou who was talking about it :p
<whitequark> ah ok
<whitequark> rqou: ^ my point stands lol

<rqou> whitequark: so what's the use case for inverters like this one (https://www.amazon.com/dp/B00T93K9KU)?
<rqou> that's only 2kw rather than 5kw though
<rqou> or are these intended for powering things not inside the car?
<lain> probably things not inside the car - my mom's an artist and we were always doing art fairs. lots of artists would cart a large car battery to their tent and run a big inverter to power various junk throughout the show, like lighting, maybe some music, sometimes even power tools for modifying art pieces on the spot :P
<whitequark> rqou: chainsaws and stuff
<whitequark> for example
<rqou> i know the large wb4apr-style inverters installed in hybrids (http://www.aprs.org/FD-Prius-Power.html) are intended to power things not in the car
<rqou> wb4apr has an interesting point that if you hack a prius or other hybrid the way he did, you now get a reasonably-decent generator
<rqou> and the generator is capable of transporting itself, and you, and extra stuff too
<lain> on the rare occasion we had a lengthy power outage, I would run my honda as a generator to power my shit
<lain> honda as in car, not generator
<lain> :P
<rqou> apparently non-hybrids aren't nearly as efficient when you do that
<lain> yeah it was wildly inefficient
<lain> hybrid would be way better, for sure
<rqou> if you look on that page wb4apr has another "interesting" prius
<rqou> it's been converted to phev (plug-in hybrid) but also has solar panels on the roof
<rqou> idle thought: i wonder if you can convert the gasoline engine part of the prius to run on CNG instead?
<rqou> most hippie eco-friendly vehicle possible? :P
<rqou> probably not good ROI though
<azonenberg> Lol
<azonenberg> personally i'm happy with my LPG-based standalone generator
<azonenberg> up to 4 kW for ~12 hours on a 20-pound gas tank
<azonenberg> to be more precise, 12 hours run time per tank at whatever load i run it at
<azonenberg> it's probably a bit worse at full load but i havent tested
<rqou> that's probably more efficient if it's fixed in your house
<rqou> but that generator can't easily be moved
<azonenberg> this is on wheels and portable, but not self-powered
<azonenberg> you have to actually lug it around yourself
<azonenberg> i want a standalone one, i saw some nice ones from CAT et al

<rqou> but wb4apr's prius is probably better for field day/search and rescue
<azonenberg> yes
<rqou> he claims the prius as a generator does 4kwh per gallon
<azonenberg> although fwiw, in my SAR unit we use a very similar portable gen (gasoline powered, not LPG, though) at base camp
<azonenberg> to run the command post van
<azonenberg> they just keep a few extra gas cans around to top it off as needede
<azonenberg> and in the unlikely event of an extended mission exhausting the gas they'd just send a sheriffs officer or one of our base camp crew out to a gas station to get more fuel
<rqou> huh apparently a 20lb propane tank is <5 gallons
<azonenberg> Yes
<azonenberg> it's about 4.7 of usable capacity
<azonenberg> if memory serves me right
<rqou> so the LPG generator is much more efficient
<azonenberg> well i was likely not running at 4 kW
<azonenberg> I think i was closer to 1
<azonenberg> maybe 2
<azonenberg> i dont know where the peak efficiency on the curve is
<azonenberg> All i know is that running all of my computers, the refrigerator, and occasionally microwave and toaster oven during my last few outages
<azonenberg> i used a pretty consistent amount of fuel, which came out to approximately 12 hours per 20-pound tank
<rqou> hmm so if it's 2kw then it's only around 5kwh/gallon
<rqou> volumetrically not that much better, but much cheaper
<rqou> btw fun fact: hong kong has converted basically all of their "fleet" vehicles (taxis, buses) to LPG
<azonenberg> yeah i noticed when i was there
<azonenberg> But I wasn't doing it for cost
<azonenberg> Cost only matters if this is say a construction site generator, and you're operating it for an extended period of time frequently
<azonenberg> My generator is dual fuel LPG and gasoline
<azonenberg> But for backup/emergency power, shelf life of the fuel matters more
<azonenberg> LPG is under positive pressure and hermetically sealed so it's good for about a decade before the tank has to be emptied and hydro tested or replaced
<azonenberg> Gasoline, even with stabilizers, isn't good for nearly as long
<rqou> wait, a decade? even if you left it outside in the rain next to your grill or whatever? :P
<azonenberg> I leave it under a tarp outside so it's not actually getting rained on
<azonenberg> and i'd likely replace it prematurely if i saw significant rust
<azonenberg> but the law/industry policy (forget which) is ten years from date of manufacture
<azonenberg> or presumably earlier in the event of visible corrosion etc
<azonenberg> Either way, the shelf life is dramatically greater, which is important for something that's primarily a reserve power source
<rqou> there's actually an lpg tank on the front porch of my apartment right now
<rqou> i have no idea who is responsible for it :P
<rqou> all the housemates said "not mine" :P :P
<rqou> i hope it's empty
<azonenberg> lol
<azonenberg> Which reminds me we havent had many power outages in the last few months, i should fire up the gen for half an hour or so to circulate the oil and keep the battery charged
<azonenberg> It has a pull cord in the event the battery dies, but i much prefer the electric start
<rqou> jump start it from a car? :P
<rqou> it's actually very hilarious/disappointing when hybrid cars decide they need a jump start :P
<rqou> and yes, my father had this happen to him
<rqou> azonenberg: can you tell from the photos if this is a rebadged finisar optic? http://www.fs.com/products/29899.html
<azonenberg> no i cannot
<azonenberg> but that is a *very* attractive price for a 10g optic
<azonenberg> i'm used to seeing $80ish
<rqou> except shipping? :P
* azonenberg looks
<azonenberg> how much is shipping?
<azonenberg> $23?
<azonenberg> That is still not bad
<rqou> but yeah, i moved my switch into the hallway so that it can be loud and i don't have to hear it
<rqou> but it's now too far for direct attach cables
<azonenberg> you're running 10gbit at home?
<rqou> one link only
* azonenberg is running 1g over multimode between a lot of things
<azonenberg> but doesnt have 10g gear yet (still)
<azonenberg> cheapest finisar on digikey is $69
<rqou> this switch is being used as a "random crap aggregator"
<rqou> it's probably not entirely necessary :P
<rqou> the uplink is 10gbit
rqou has quit [Remote host closed the connection]
rqou has joined ##openfpga
<azonenberg> ah i see
<azonenberg> in my case i'm using 10g (among other things) as an upstream link for the starshipraider
<azonenberg> which will easily be capable of saturating it
<rqou> hmm, thinking about whether i should buy another intel x520
<rqou> $150 or so
<rqou> for the two port version
<rqou> yeah, i just ordered another x520
<rqou> now i can upgrade my NAS and get 10gbit
<azonenberg> i have a lot of upgrades i want to do, including a dual xeon mobo for my desktop :p
<azonenberg> But i'm trying to save for a house
<azonenberg> and those things are... not cheap :'(
<rqou> do you know if fanless skylake is a possibility?
<rqou> my nas is currently a fanless bay trail :P
<azonenberg> No i dont know
<rqou> the current upgrade plan is "the weird skylake pentium that has ecc ram"
<rqou> which is very budget-friendly :P
<azonenberg> my nas has a spare pcie slot now iirc
<azonenberg> so i could put 10g on it today
<azonenberg> i just dont have anything for it to talk to yet :p
<rqou> i got a 10g nic because of you actually :P
<rqou> you pointed out on your blog that 10g ethernet is one of the simplest high speed "get data into pc" interfaces
<rqou> no need to mess with tuples of 16-bit integers or similar crap
<azonenberg> Yeah
<azonenberg> It is
<azonenberg> And i'm excited to finally get to play with it soon
<azonenberg> things just keep coming up :'(
<rqou> hmm i just realized i should fix the structural masking tape currently present in my NAS :P :P
<rqou> my NAS used to be a wifi router
<rqou> so it has two wifi cards in it
<azonenberg> lol
<rqou> but nobody makes full-size pcie wifi cards anymore
<rqou> so i was mounting mini-pcie ones on adapter boards
<rqou> but i didn't have the correct standoffs
<rqou> but due to the way the connector pushes on the card, you can hold the card in place with masking tape
<rqou> yes, this works
<rqou> hopefully the two wifi cards don't interfere with each other too much? :P
<rqou> one is an ath10k 802.11ac card on 5ghz and the other is an ath9k 802.11n card on 2.4ghz
<rqou> i never benchmarked to test if the bay trail celeron is even fast enough to shuffle packets at the maximum data rate

<rqou> azonenberg: not sure if i should describe this NAS as hacky, adorable, sad, or some combination of the above: https://goo.gl/photos/JYi5AFd1uFQuWCT97
<lain> ha
<rqou> notable features: mATX in a huge crappy case
<rqou> no fans at all
<rqou> picoPSU
<rqou> masking tape wifi card adapters
<rqou> no cable management
<rqou> it's actually pretty creepy when you boot this without a hdd because it makes no sound at all
<rqou> oh and * intel server gbe nic plugged into the gpu slot
<rqou> because the gbe nic is x2 or whatever
