					<description><![CDATA[&quot;Because they didn’t make that assumption&quot;

No, they still did.

&quot; It’s like how you say the range of the cars is irrelevant. &quot;

It is.

&quot;Yet I used the range in my calculation.&quot;

That still doesn&#039;t make it relevant.

&quot;You are correct that kwh/mile is just as good &quot;

Nope, it&#039;s the only measure of any use. If the fleet of cars were magically upgraded to double the battery capacity by some weird alien overlord, the range of all the cars would double. But the number of cars possible to service would not change a jot. Despite the range doubling.

You don&#039;t WANT to get it. Ironic given your whining earlier.

&quot;No matter the size of the daily commute, even if every car is coming in for a full(or is it half) charge, you still get the same 156 cars number&quot;

Nope. You got 1-2000 for example from the same cars driven the same way.

And if the cars were doubled in range because it was more efficient by a factor of two, then you&#039;d double that number.

Showing yet again that the number given is BS and the range is a nonargument.]]></description>

					<description><![CDATA[Zebra, no I meant the area of the car.  1000 sq meters per charging station, and probably each charging station supports 50 cars, comes out to 20 square meters or so.  

&#062;You bloviated about how it wasn’t written down that they assumed it was a daily commute of 200 miles. ONCE you asked what the daily commute was. You then ONCE reworked the figures to something around 1-2000,

Because they didn&#039;t make that assumption, hidden or otherwise.  My calculation of 1000 cars was different from their use of 156 cars, which was to support it.  You still don&#039;t get it, as usual.  It&#039;s like how you say the range of the cars is irrelevant.  Yet I used the range in my calculation.  You are correct that kwh/mile is just as good and the range can be skipped.  Yet if I had calculated the time of charge from the range, then arguing the size of the range is a wrong assumption would be flawed, because it is the same no matter what range I use.  No matter the size of the daily commute, even if every car is coming in for a full(or is it half) charge, you still get the same 156 cars number.  
Daily commute 1 mile per day, you still can have 156 cars per day getting a half charge.]]></description>

					<description><![CDATA[MikeN,

I think you meant to say that &quot;solar panels the area of the house (not &quot;the car&quot;) would suffice&quot; for home charging. Which might be correct, except that you are doing your thing of being vague, because you don&#039;t specify what &quot;home charging&quot; would be quantitatively.

I&#039;ve put in a fair amount of time trying to give people the foundations of what is needed to objectively and usefully discuss these questions (electric circuits 101). If you are too concerned about getting something wrong, or not maintaining your ideological purity, to even &lt;b&gt;try&lt;/b&gt; to use the correct terminology with respect to power and energy, and look at this from an engineering design perspective, then I am truly wasting my time responding.

Wow&#039;s last paragraph at 136 sums things up pretty well. 

There are multiple different scenarios and situations. You take the fundamental physical facts which I have laid out and apply them to each, &lt;i&gt;based on the specific goal you are trying to achieve&lt;/i&gt;.

If you aren&#039;t willing to stipulate what the goal is in the first place, what is the point of having a discussion?]]></description>

					<description><![CDATA[&quot;It will be quite a while before any such facility would be “overbooked” by people taking 600 mile road trips, all arriving at the same time and expecting a super-fast charge.&quot;

And if it ever happens, someone will open up another charging station if there&#039;s money to be made there.

Or people will stop driving 600 miles on a charge and stop pretending that their EV is the same as a mythically fast and efficient petrol car. And not take dangerous 5-10 hour continuous drives.]]></description>

					<description><![CDATA[&quot;by saying Wow has a point, you are saying that you are making a ‘hidden assumption’&quot;

Nope. If he;s saying I have a point, which point do YOU think he&#039;s saying I have a point at?

&quot;&#062; And the optically evident source for that…?

Your post of the range of a Tesla.&quot;

So you&#039;re saying I have a point? That if you wanted to claim how many cars, it ought to be how many charging stations per tesla could it service? But the calculation doesn&#039;t require the range of a tesla. Or the range of any car. Just how many kwh is used per mile, and how many miles per day on average is used driving about. Range of the car isn&#039;t there. Only efficiency.

Hell, petrol stations aren&#039;t rated for how many you need per thousand cars. How many you need is more relevant for petrol cars, though, since you&#039;re not allowed to make your own petroleum distillates.

But at least you&#039;re getting that the number of cars should be in the many hundreds or thousands if you wanted to put some metric like that up and the slashdotter was underreporting, making it look worse even if you want to claim it wasn&#039;t malicious.

Per charging bay, solar panel acreage really only matters if you have no storage at all but need to supercharge based off the output straight out, but nobody is pretending that there&#039;s no storage at all.]]></description>

					<description><![CDATA[The point to make, now we&#039;ve all gotten the idea that &quot;counting how many cars can it service&quot; is a fucking stupid idea since it doesn&#039;t matter in calculating power supply, is that the engineers at Tesla have the figures that would let anyone know if it can be disconnected from the grid, and why it would make sense.

And they think that there&#039;s a case for it.

All we can do is discuss how society would change if there were more such stations around and more EVs using them. Would we charge up at the mall or supermarket, making fast charging needless? Would we accept &quot;free parking with power&quot; at work or shopping if our cars were used to stabilise the grid? Would supercharging become needless for 99% of travelling because we only need it along highways for long journeys to cut down on journey times? And could that be nullified if they were common enough that we could use the driving break to charge wherever we happened to be when we felt like it?]]></description>

					<description><![CDATA[Zebra, by saying Wow has a point, you are saying that you are making a &#039;hidden assumption&#039; that &#039;every day every car has to fill up all the battery, indicating that the average US commute is 200-300 miles per day&#039; as Wow posted in #11.

Do you think that is an error in your calculations?  
Wow obfuscating as usual.  BBD pointed out this assumption is not in what Wow posted, and gets accused of not caring about accuracy.]]></description>

					<description><![CDATA[&#062;So.there would be lots of facilities with two or three charging stations, with the total capacity provided by 2.000 sq meters of panels if it is off-grid.

You are still reaching the same numbers, about 1000 sq meters per charging station(for at home charging, solar panels equal to the area of the car should suffice right?).  Wow brought up the &#039;hidden assumption&#039; of daily commutes and I went with that.  Looks like they don&#039;t need that many then.  However, if it is for long drives, then presumably the superchargers will be placed on highways and 2-3 chargers will be way too low, while city places can get by with just a few.]]></description>
