i remember the last time i over clocked a computer. had a 300A running at 924 and stable. used two peltier pads and encased the heat sinks to pipe in water. Was a really fun build. before that i had a 233 mmx up to 405 stable,
These examples sort of prove that it's pretty hard to have a one size fits all role the F35 is supposed to perform.
Exactly, the only way you can make something do anything and everything, or take something and use it effectively for something it is i capable of doing requires an insane amount of money and effort which in the end will be unsustainable.
Lucky, i'd like to get to know people who can build cars like that. in my region (NCR) we have a lot of active drivers, and a fair number of national champs to learn from. But most of them are Stock/Street or SP class drivers. We have very few real Modified drivers and almost no real modified cars/builders for AutoX.
So that first one looks like it was at Carolina Motor Sport Park down in Kershaw SC, that turn he spun on is called the "twitch" for a reason. he obviously over steered into it (notice hitting the rumble strip) and lost control when he tried to back out while still accelerating. didn't bother watching the rest of the vid
In your link the up to 1500v is for the British Standard BS 7671
The wiki entry also states that the US coverage for low voltage is 0-49v and is cover by NEC 250.20
I will note that the NEC also has requirements for high voltage and that NFPA-70E does have an overlap in this area, but the overlap is in that the NFPA-70E is specifically covering safety requirements due to Arc Flash which the NEC does not cover. So you are double regulated but not on the same elements (NEC would cover wire sizing, insulation requirements, labeling, isolation methods, etc.)
will someone explain what BMW is doing with the i3? When I think BMW, I think sport sedan. That thing has the specs of a Nissan Leaf and the looks of a Scion Cube. I'd expected something Tesla-ish.
My bet is they are hitting the target market that wants to say "i'm wealthy, and i'm green" who are not wealthy enough to drive a Tesla/i8 and are just snob enough not to drive a Leaf.
From a "looks" prospective i think it looks like just about every sad rendering of a car of the "future" crammed into a echo box frame. To me the i8 looks good but the i3 is up there on the ugly meter on par with the Pontiac Aztek
once you get above 300 volts you have to start really dealing with NFPA-70E Arc flash regulations (below 300 is only an issue if "exposed" other wise it is avoid contact).
If you then start getting above 750 and in the kV range you start dealing with hard regulations around approach boundaries
751-15kV is 2'2" restricted boundaries (requires PPE and training) and 7" prohibited boundary (meaning you can't be within 7 inches of a live line in that range period)
My bet is that no car manufacturer wants to deal with having to design a charging station standard which requires people to hook it up, step away, AND have a method for ensuring that there is zero possibility of someone within the area.
When you have power in that voltage range someone will be liable for safety in that area, and car manufactures can not insure that the operator of the car and charging station have had the appropriate training or PPE available so they most likely won't go there. Even on industrial equipment that uses this level voltage most OEMs have safety interlocks so that you can't accidentally get into an energized compartment.
Sorry you just won't see real high voltage charging systems for consumer cars. This is one of the reasons they will have to figure out how to deal with the current side of the problem.
And at that point the level of engineering you are doing for the parts brings you back to bespoke purpose built hardware - now you need an OS and application which can manage it all which doesn't' yet exist for that hardware. All you would be doing is re-inventing the wheel to compete with the existing suppliers.
I am by no means a tech geek, but I have DD-WRT on my routers because...
No offence but the fact that you are comparing your DD-WRT home router with a Cisco infrastructure device and asking why we trust these vendors really highlights your comment.
Hardware wise there is no comparison between Cisco business & infrastructure devices and what people normally load a variant of Linux on. I'm not saying it couldn't be done, but the Cisco IOS (and Juniper's OS) is an extremely specialized OS designed along with the hardware to serve a specific function.
Now I will say that lately they are moving to more modular application based products (layer 4+) which are far more software based on marked up hardware, but for Core routers and switches (later 2/3 devices) there isn't really a quality substitute other than like in kind vendors hardware. At this point you just can't really "build your own" hardware and OS combo which can truly compete and be open source at the same time.
The thing is, it's hard to see where Uber's costs are. They develop software, but that's a pretty small investment considering the hundreds of thousands of rides a day people take.
This is my question, i don't see how they are spending the money they are making as part of operational costs. While their model and implementation is interesting and novel and works, it isn't exactly one which requires a major investment, nor maintenance costs to run.
Keep in mind there is a major difference between monitoring and controlling. To control/run you have to be able to provide input into the system. It is this input access which opens the door.
So i have mod points for once, went to used them and realized we need to add an option for "stupid".
Sorry but your first line
What makes it intrinsically illegal? Just because there is a law?
really? Why yes it is illegal because there is a law, that is kind of how laws work.
If you don't think it should be illegal then you go and get the law changed. Very much exactly what the Gay rights movement has been doing to get Gay Marriage legalized.
You don't just look at the laws, proclaim your self better than everyone else and ignore them. If you don't like how the laws work, or the world they build then go get them changed.

If you are in a " you're 1099 and here's your desk and working hours and no we're not paying you by the hour" situation then you need to file a grievance with the DOL and IRS. Trust me i work in an industry where we utilize contractors all the time, and i can promises you that they are violating the law, and you will win if you go after them (and the government will help you with that too). Sadly your "winnings" is usually that you are now a "employee" and the "employer" just fires you. But they end up paying a bunch of back taxes and fines/fees. So if you don't' like them and plan on leaving anyways, file a grievance.
I just create a situation that violates all of their problem trees. I have physical loop back adapters (different ones for different types of service) that allows them to do a local loop checks but provide zero actual dynamic communication. That normally gets me thrown right up the chain to someone i can actually talk intelligently with.
I would agree with you if you only look at their top shelf high priced speakers but they do make some very good quality more traditional speakers which offer great sound quality for the money.
I've got two floor standing load speakers and two of their book shelf variants of the same line. Both offer wonderful sound quality and while not cheap in price where not super expensive. I believe i have ~1,000$ total in for all 4, and they have lasted me now 17 years with zero signs that i'll ever need or want to get a different set.
I will agree that a lot of B&W speakers on their top end are works of Art as much as they are speakers, i just can't justify that for a speaker (although i do for paintings so i also can't argue with what people view as Art)
i personally love it, and a few years ago bought a life time membership (even after buying several albums from them).
Only thing i wish was that their phone app was better (and had random across favorites) and that they had a desktop player like PandoraOne so that i don't have to leave a web browser always running to listen (and the player would work with media keys for play/pause/stop)

anyone remember "Code Red" and "Code Green"? that was a fun month
i remember the last time i over clocked a computer. had a 300A running at 924 and stable. used two peltier pads and encased the heat sinks to pipe in water. Was a really fun build. before that i had a 233 mmx up to 405 stable,
that was years ago, good memory's,
These examples sort of prove that it's pretty hard to have a one size fits all role the F35 is supposed to perform.

Sounds exactly like the F35 program to me.

it's still a fun car to watch race,

With enough effort you can make a Jeep worthy of racing.

to be fair that is the only one i know of which i would say meets the need and as you can see requires heavy modifications.
Cited in my post NFPA-70E

So you are double regulated but not on the same elements (NEC would cover wire sizing, insulation requirements, labeling, isolation methods, etc.)
While i'll agree that 800v wouldn't be bad the regulations lump 751-15kV together as that is where the uncommon voltage starts.
Also not ethat when you start getting in the 700+ range minor fluctuation in voltage (by %) can be major in overall impact.
They could do it, but they would need to get an exception to the regulations, which would not be an easy thing to do.
I've AutoX'ed a Tesla Roadster, if it is setup right that thing is a beast. haven't had a chance for a model S yet, would be fun.

all i care about is single and double bights. they can figure out the math, i'll use what i know is safe for what i'm doing.
now if they figure out that something that is currently believed to be safe has a previously unknown failure method, then i'd be interested.
The thing is, it's hard to see where Uber's costs are. They develop software, but that's a pretty small investment considering the hundreds of thousands of rides a day people take.
