nerate power only during the day, and wind farms only generate power when t he wind is blowing makes it easy to charge them up when these cheap sources of power are available.
at the people who look after the grid are worried that they'll too much pow er going the wrong way for the current grid to cope (which may even be true , but could well be yet another bid to allow them to invest even more in po les and wires and charge even more for their services). Thye'd welcome havi ng a lot of electric cars around that they could charge up when they'd got more power coming in than they could easily sell.

a tiny bit.

The frequency change in the grid is due to the trade off between the moment um of the rotors on generators and the power input/output. I think solar P V converters will simply track the frequency without raising or lowering it .
sources are configured to automatically not push the power out. They aren 't connected to the main lines. The voltage on the local lines vary with l ocal loads and other factors anyway. Anyone know for sure?
all the power is solar. My guess is overall, maybe 10% comes from the pane ls. AC units consume LARGE amounts of power and in Chicagoland in summer it
uire power and the panels are dead and even with battery storage, I serious ly doubt they have excess power during the day.
imates. The car is harder to move because everything stiffens up - tires, l ubricants and just driving on snow is equivalent to a constant incline. The batteries are less effective in the cold and the driver doesn't want to be in a cold car. You don't have an engine with waste heat to tap into which means using electricity for heat. Granted a heat pump (are those used in ca rs?) is less wasteful than resistive heating but you don't have that much t o begin with. Then the 'fun' part. Re fueling can take hours and your range can drop to less than half. Just what I want. Drive 150 miles and then ch arge for an hour and drive another 150 miles. Hybrids make a whole lot more sense.

model X. Yeah, he has some issues, but for the most part the cars just kee p on truckin'.
That must be why GM is dropping the Volt. ;)
If you got stranded driving to Truckee from SF you would have to be a total moron. There are 84 Superchargers along the 190 mile route... 84! That i s more than are available on a 500 mile trip from central VA to Crossville, TN that I drove often. I guess it pays to live in the epicenter of Tesla ownership.
The four wheel drive and low center of gravity of the Teslas would come in very handy in the snow. I had no trouble in the recent east coast snow sto rm. I was headed over the passes as the storm came in and left going back the day after the storm cleared out. Anyone trying to cross major mountain s in a snow storm needs to have their heads examined.
Yeah, so the electron pumps are always free, right? Unlike gas stations...
Only a fool would risk life to do that. But then a fool could just as easi ly do it in an electric vehicle.
They aren't expected for a couple/few more years. Tesla doesn't announce h ard delivery dates on any of their cars. Unlike electronics where you can find someone to build your circuits in a matter of days if you need it, bui lding cars and trucks takes as much time to build the factories as it does to design the cars or trucks you want to build.
I have no doubt GM will be a major player in electric autos. But they are hampered by tradition. I don't know if you actually need to sell electric cars any differently than you do ICE autos, but GM and the other "big iron" makers will be hard pressed to do so. I looked at the BMW i3 web page and it tells you little about the electric aspects. I guess long term that is the way to do it. Once the market penetration is in the double digits I e xpect all the gear heads will have EVs and it will be more middle America t hat needs to be sold.
One thing I noticed is that GMs initial EVs will be sold in China, not the US. I guess there are many reasons for that having to do with marketing as well as lower labor costs. Maybe because they don't want John Larkin snip ing at their efforts. lol
A 20 unit road-train wouldn't impact the highway any more than 20 tractor t railers which is what they would replace. I'm not sure how practical they would be. I suppose they could reach a rerouting point where they would us e 20 drivers to take them to their destination.
The taxes would also be the same as 20 tractor trailers since that is what they are. The electric part is different. In at least two of the four sta tes I've looked at, they have a special tax on electric vehicles to compens ate for the loss of gas tax revenue. I'm certain they will tax EVs, but it 's not quite the same. Out of state EVs won't be paying taxes in states th ey travel through. Maybe the chargers will get a special tax.
LOL! Talk about putting the cart before the horse! What you mean to say is the autos are not very friendly to Japan. No one cares about the autos. They are machines that either serve or are pointless.
Tangentially related when black athletes peacefully protest for 30 seconds prior to going about their jobs many Americans want to boycott the NFL.
When the (primarily white) trucking industry didn't get what they want the way they protest is they go on strike, block traffic, smash things, make violent threats, riot, set stuff on fire, and threaten to trash the economy.
The i3 isn't much to write home about. Limited range, not that much more than a Volt on a good day. Charges slow. The dinky range extender engine and 2 gallon fuel tank is an $8000 option.
You think GM's effort was lame-duck (I obviously disagree) the old-guard European automaker's efforts have been lame in the extreme like they're trying to sell EVs on the leather interior and wood trim.
The Volkswagen Golf EV is kind of the best of the bunch but it's pricey for what it is, not that much less than a Model 3 now so like why bother. The sales figs reflect that
GM marques like Chevrolet and Buick have cachet in China; in the US we think of Buick as like a grandad car but in China Buick is what you drive if you're middle-class/new money to show you "made it", sort of like BMW and Mercedes in the US. It's an "import"
Also if you see one in person check out the tires on that thing! There's a reason a lot of the promo photos are from the side look at it from the front or rear to see the teeny little tires! They're narrow like motorcycle tires. Don't know if I'd want to be driving that thing in the New England winter....

Here is one of the locals using the Supercharger you are referring to.

Here's one of the chargers in use...

Must have been some time ago. They are all older model S. Now it would be a mix with newer model S, model X and model 3s included. That must be why they are adding even more superchargers in the same town.
And a full battery is too. Only an idiot would not charge fully before goi ng on a trip and only an idiot would continue to make the same silly claims after being informed of the truth.
"Winter" encompasses a lot of conditions like fresh snow vs. compacted snow I don't think there's any way to make general statements like that. The tire manufacturers themselves often say otherwise.
In general the stock ultra-low rolling resistance tires that come on many EVs i3 included aren't good all-weather tires. On a Volt or Tesla you can at least swap them out for whatever you want but the i3 takes a custom tires size most tire joints don't even carry it. Oh you can't rotate them, either.
So your narrow tired car will skid a lot more sideways than it will forward ?
I took a motorcycle out in the snow once. I needed to get home and there w as already four inches on the ground. It was actually quite stable. I cou ld open up the throttle a bit and the rear wheel would spin and start to sl owly come around to the side. Back off the throttle and it would return to following behind. That was an old BMW with the cylinders below the camsha ft. I didn't try any cornering at speed. lol
I replaced my Volt's stock Goodyear ultra-low-rolling resistance tires, that were wearing out in under 30k miles, with the lower rolling resistance variant of the Continental PureContacts. handling and stopping distance is noticeably better on wet pavement.
I can't say exactly how much range loss there is on battery power the seasonal temperature change going into winter causes a much larger rage reduction. On gas power it's down to 39 mpg on my thrice-weekly
30-mile-flat-highway run from my previous winter-average of around 41 mpg
