To be fair the caption says, "SolarCity's 1 GW solar panel manufacturing facility in Buffalo, N.Y. is expected to open in early 2017", and the picture shows active construction, and it is only 2015. So they have year to finish the building and add Solar to it.

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.

Sounds exactly like the F35 program to me.

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

Cited in my post NFPA-70E

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.)

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.

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.

so again back in the same camp

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.

Brain off-line, please wait.
