Umm, no. Your bullshit meter is being a bit over active. Lots of bullshit attached to this article, but my comment is spot on truth.
You talk about danger Fromm fast rechargers? It just looks like a gasoline pump. Anybody can use it. Thre's all sorts of interlocks, so you can't remove the plug from your car until the cable's bee ndrained, for example.
You talk about the Nissan leaf not being a good example? It's the most popular EV in America, and most upcoming evs will the the same form factor. So it's a pretty good example.
You miss the point of a buffer. If you only fill up one car an hour, then you only need to draw enough current to fill the buffer over the course of that hour. So this reduces the load at any given time. If your charging needs are more cars, then you add more buffer until you maintain your desired draw.
You somehow scale up from one EV to a fleet of a million EVs. My point was about one charger, which draws 20kva at most, and does not threaten the grid like your super secret SF project. It's an interesting question of how to support a fleet of evs, but not an impossible one.
Lastly, I don't like your tone, so go fuck yourself.
but it's not like you can request an 80% full vs 50% full. you take what they have. it raises a good point, how do you know that they're not ripping you off?
I see your porint, but it might be a little overblown. The leaf has a battery of 24 kwh, and you likely won't find any EVs over 50kwh in the near / mid future. so the 4x is a little high. second, for longer-range driving, no big deal, different strokes for different folks. If your driving needs ar compatible with an EV, then you can get an EV. If an EV can't meet your needs, then you can get a gasoline car. Your comment is common, and it implies that this is a death knell for EVs, like they're impractical and will fail. Not true, just different strokes for different folks.
sorry, no. cars aren't really weight constrained, at least within reasonable bounds. more wieght means your MPGs are lower, but it's not a hard cap. my accord weighs 3,000 lbs. if you design a lighter car at 2,500, you still have plenty of room to add heavy batteries. on the other hand, space constraints are real and fixed. you only have so much space based on wheel base, frame, other needs, etc, so any changes for space considerations have significant and possibly fatal design tradeoffs, while weight considerations have less impact.
wtf? why wouldn't you want a complete charge? It's like going to exchange your propane tank but requesting a half-full tank. perhaps you're worrieda bout the weight of all those electrons?
home charging is fine for most uses. A 220 V connection can charge a leaf in 3 hours, and a 110 connection can charge one in less than 8 hours. So for home overnight charging, this is fine. level three fast charging is a complimentary technology for when you need to get topped off quickly.
I saw a fast charger (level 3, it's called) at the san diego gas and electric headquarters. Both of your issues - grid impacts and amount of wiring are not a concern. The level 3 charger dumps 50kVA into the car, and can charge a leaf from 20% to 80% in less than ten minutes. The charger has a built-in 30kWh battery pack to act as a buffer, so it only pulls 20kVA from the grid. This keeps it below a threshold that limits high-power applications. Not sure what you mean by thick wires. The cable that plugs into the car looks like a gas pump tube.
the goal of fast charging is to use it in combination with home charging. most people can charge at home, but fast charging is available as well. it takes a village! (of chargers, that is).
Also, remember that electric motors are 3x more efficient that gas engines (80% thermal efficiency vs. 25%), so batteries don't need to get parity with gasoline in order to be comparable.
tfs says that the energy density is like gasoline and 10x lithium ion. but it's talking gravimetric density, i.e. kwh per kg. The only thing that matters is volumetric density, i.e. kwh / liter. This is because cars are space constrained, not weight constrained. So nothing to get excited about for vehicle range, because we have not data on it. For all we know, it could be worse. likely it's about the same as li-ion, because most of the battery volume is taken up by packaging and cooling, not the active material itself.
The reason it can be lighter is because there is no cathode in the battery. Most batteries have an internal anode, cathode, and electrolyte. In this case, the cathode is replaced by ambient oxygen, so it saves weight. attn pedants: dont' lash out if i have my anodes and cathodes confused.
yes, but so what? from one perspective it's "unfair" because county isn't profiting from its work, but from another perspective the county isn't going to monetize it anyway, so who cares if somebody else does. A healthier perspective: county did awesome award winning work, and it can improve the efficiency of other counties by distributing it widely. the best way to do this is to add a profit incentive!
this makes no sense. if the county were to enter into an agreement with a private company, where they promise to send them any updates, then yes, perhaps there's liability. but if there is no updates and no contract, then of course there's no liability. It's like if I scraped slashdot to make a compendium of your comments, and sold it as a book of wisdom. Somebody sues me for selling lousy wisdom. it's not like i can turn around and point the finger at you!
I'm pretty sure this makes no sense. The price of the bread depends on how the demand compares to the supply. If everybody just wants one loaf, then all the bread is free. if people want more than one loaf, then bread is a scarce commodity and will be assigned some value. Then you have to figure out the price sensitivity - how badly do people want the bread?
so while I agree with your first comment, that the situation is far more complex than your example, I disagree with your second comment, that the basic principle is the same.
The county just wants to make sure they can't be held liable and have somebody turn my work around and make a buck.
who cares if somebody makes a buck? this sounds like sour grapes on the part of the county. They're in no position to monitize it (they shouldn't be anyway, or else they're wasting taxpayer money on business ventures?). Let somebody else make some dough.
i wonder if teller will be called to testify? that would be a first! seriously though, did teller copywrite the work? this sounds like another step in a business negotiation than an actual lawsuit.
yes, the cost from consumer lawsuits is probably relatively small in comparison to the repair costs. But what is the cost to corporate reputation and customer satisfaction? Right now Apple is tops in brand positivity and reliability. Any hit to this would cost them dearly! This is the calculation that jobs/cook made/is making, not a lawsuit calculation.
maybe they didn't have any C4s on hand. I broke my iPad (my fault) and they gave me a refurbished one for free. Not the newest model, but not too shabby nonetheless.
Apple promised to replace parts they knew to be defective for up to four years
this seems reasonable for me. It's not like all parts were defective - there was a higher error rate. Normally the computers have a 1 year warrantee, and you can buy a 3 year for $200 I think. Because of the nvidia thing they extended the warrantee from 1 year to 4 for free on the affected part. This is standard for product manufacturing - if there's an indication of a problem, offer longer warantees.
The issue seems to be apple not honoring their promise within the four year window. but this sounds like isolated cases, and could be for any number of reasons (user voids warrantee, the problem turns out to be a different part, etc). Without knowing the deets we can't rule on if it's egregious or not
in general, I've found the genius bar people to be extraordinarily generous in fixing issues, often for free when it was my fault. Once I cracked my iPad LCD and they gave me a replacement refurbished one for free.
not to mention the benefits of talking to genius bar people for support, rather than calling some foolio in india.
I think this argument is interesting, but is ultimately a false choice. You can't have android on the lumia because it doesn't exist that way. Is like saying, iPhone would be better with android on it.
The bet thing ms / Nokia can do right now is take their lumps, invest in advertising, and have faith that they have a great product on the shelf. Build it and people will come.
The only concern is that while ms has deep pockets to take a bath for a while, Nokia is more precarious. Acquisition, anyone?

ok, fine. aside from the caveat "anybody can sue anybody else at any time," my argument above still holds.
I totally believe it. I bet if I had 1,000 dell laptops they would hop on my problems. But when I have just 1 laptop? screwed! genius bar, please!

As Steve jobs said, "real artists ship."
Not surprised that Google didn't return a reference. I made it up. sounds nice though, no?
