If you have daily commutes of less than 50 miles, you never use gas, but if you want to go 500 miles, you can still do it with this car, no need for a second car. I plug it in to my 120volt outlet each evening and it's fully charged in the morning. No need for a separate charging station. In fact if I need to, I can just plug it in here at work.. Full charge at work costs 40 cents and that will take me 45 - 50 miles. At home it costs about 70 cents for a full charge. Razzy |

If you've already had the wiring done, you'll be waiting a long, long time, unless you don't care about charge times when on road trips.

NASA's biggest worry right now: What if something goes wrong with the Webb telescope?
Chris L Peterson:
In terms of features, we need something SUV like - no smaller than a Highlander or Outback (got those two Great Danes to move around), with decent ground clearance (several miles off road just to get to our 3/4 mile driveway for the new house we're building), and AWD (rather steep off road in places, with marginal maintenance in winter). Something will come along in the next few years, I'm certain. Indeed it will; everything is in flux. Only question is who will release the breakthrough car. Your only choice now is the Tesla X. It will hold your puppies. It doesn't do the kind of off-road that you see in the Jeep ads, but unpaved roads and tracks don't faze it. A big plus is that if you should pave those several miles that you must traverse to get to your driveway it has a top speed in excess of 150mph. -- I agree with almost everything that you have said and almost everything that you will say in your entire life. usenet *at* davidillig dawt cawm |

A 300 mile drive requires around 100 kWh. Do that overnight and you don't need anything you don't already have. On the road you can often take advantage of fast charging stations. |

Are you saying everyone already has a 100 ampere fuse in their home electrical wiring? Because that's what's required to charge 100 kWh overnight, assuming you switch off the rest of your home. In Europe, a 50 ampere fuse will be enough. |

Almost every home has 220V service with 30-50A fusing. Of course, not for every outlet, so it's true that a new outlet might need to be installed in the garage. |

A 300 mile drive requires around 100 kWh. Do that overnight and you don't need anything you don't already have. For people who only *ever* drive locally, sure. For people who occasionally want to take a road trip to more than 300 miles away, it becomes untenable. On the road you can often take advantage of fast charging stations. The fastest charging station out there today is 50 kw. Porche has proposed 350 kw (at $250,000 each), which will still take several times as long to "fuel up". And they will require special power circuits into the charging stations, even for a single charger. To meet the "3 minutes for 300 miles" standard for gasoline requires, as I said, about 3 MW per charger. We've gone over this before, and you knwo I'm right, and you know you're full of ****. -- Terry Austin Vacation photos from Iceland: https://plus.google.com/u/0/collection/QaXQkB "Terry Austin: like the polio vaccine, only with more asshole." -- David Bilek Jesus forgives sinners, not criminals. |

The circuit might be labeled "EV charger", but the electrons will be just as happy to power a welder, or whatever else you ask of them. In any case, the choices to own an EV, to provision a charging home station, etc., are entirely voluntary. For now. A number of jurisdictions are planning on changing that, whether the technology is ready or not, like California. (Soemthing like 25% of Americans rent. How many landlords are going to drop $50k per apartment to install charging stations, without jacking up the rent beyond what's possible for most tenants to pay? And what about people who have *no* off-street parking?) Charge times (and charging at all) are an obstacle with no practical solution, even theoretically. -- Terry Austin Vacation photos from Iceland: https://plus.google.com/u/0/collection/QaXQkB "Terry Austin: like the polio vaccine, only with more asshole." -- David Bilek Jesus forgives sinners, not criminals. |

If doing these things doesn't make sense to someone, if they lack the means to overcome shortcomings, or they just don't have the desire to bother with any of it - then they should not go down this path. -- Email address is a Spam trap. |

You've said some silly things over time, but this may be the silliest. Feel free to describe how over 600,000 businesses that currently sell gasoline can replace their pumps with 3 MW charging stations in our lifetime. And how peop,le who rent, with no off-street parking, can get access to a charger at all, every evening. You're really good at neamcalling, but you will _never_ address the actual issue.
