No, Tesla proved no such thing.
Check the figures i quote above.
Umm... let's see. 400 mile range, no half-ton piece of steel to weight it down. High energy efficiency because you aren't trying to convert ICE into Electric in the first place... yea, those figures point to electric being hands-down better than hybrid.
The Tesla battery (fully charged) holds about 60 KWH. The only place you're gonna get the kind of power it takes to charge that up reasonably quickly is off the grid.
Wrong. First off, depending on the model and size, it can hold anywhere from 45 to 85 KwH Second, you are assuming several fallacies.
Lessee, 220VAC power. Assuming 80% efficiency in conversion and delivery from source to car battery, that means you need 75KWH to charge the bettery. Assuming you pull 50 amps, that's 11 KWH/hour. Which means almost seven hours to fully charge that battery. (Even if we assume 100% efficiency - which ain't gonna happen - you're still looking at approaching six hours.)
And i find it very difficult to believe that "carport top solar" or an individual wind system will deliver that kind of juice.
Really? Because I see it happening all the time with solar and wind powering individual homes. But you have several fallacies:
1) You assume I will be running it dry on a daily basis. Very few drivers put that much mileage on their non-commercial vehicles.
2) You assume you won't be storing energy during times when you are not charging your vehicle, which is utterly ridiculous whenever you talk about solar/wind power. One of the main drawbacks of such power supplies is that they are only available at certain times, so you generate constantly whenever it is available and store it. So yes, plenty enough to top off your vehicle on a daily basis.
So.
You can drive it three hundred miles on a charge (i think). That means that you'd better limit your trips to 150 miles.
Self fulfilling prophecy. "It can't work because it doesn't work and therefore it won't work". If the switch to energy was made, instead of gas stations, you'd have recharge stations dotted all over the place, due to demand for such. With such a long range for vehicles, and the ability to 'refuel' at home, the only people needing such stations would be those taking extended trips, or the forgetful. A much lower percentage of the actual driving community, but still enough to make it economically viable.
Currently, you can completely recharge the 85 KwH battery of a Tesla Model S in two hours. So you plug it in when you go shopping, and when you are done, you have at least enough juice to get back home. For trips, you recharge when you take breaks, like seeing the sights, taking a lunch break, and stretching out your legs. Heck, this could revitalize the hotel industry if they install plugs for vehicles and charge you for the electricity you use.
A hybrid is a better solution than a full electric, because it's not range-limited. And a plug-in hybrid is better than a straight hybrid.
See previous rebuttal. A fuel-burning vehicle is range-limited based on ability to refuel as well.
GM is losing that kind of money on the Volt because nobody wants one - they predicted sales of 40,000 for this year, and as of last month, had sold only 13,500 ... and that was with a month of trying to blow them out the doors with $199/month leases last month. And they've got $1.2 billion in development costs tied up in the thing.
Because it is a piece of crap and a joke. Heck, the Toyoda RAV1 is rolling out with MUCH better performance numbers and no engine. Their 'development' is also a joke. Purely throwing money away for the sake of throwing money away, considering LIon batteries are a fully mature and developed technology. You could buy a better one than is found in the Volt off the shelf. And the inefficiency of the ICE to electric conversion is another bad joke. As well as completely obsolete. Heck, removing the engine block and fuel tank will free up enough weight to at least triple the car's electric range.
Electric cars will be dependent on the grid for the foreseeable future ... and that means fossil fuels. (Much as i'd like to see a rational approach to nuclear, it ain't gonna happen fast enough to make any difference in this matter.)
And they'll only be good for 'round town or recreational (short range) driving, until someone figures out how to transfer 60 KWH in five minutes or less.
Without the batteries exploding.
vast majority of vehicle usage is 'round town'. That was the excuse for the Volt's pathetic range, wasn't it? The advantage of the Tesla vehicles' 300 mile range is that you have the option of taking longer trips on those occasions when it is warranted. I will agree that fossil fuel plants need to go the way of the dodo, but hey, that's politics and kickback systems for ya.
===========================
And, speaking of "performance", you might want to consider that this year's LeMans winner, an Audi R18 E-Tron Quattro, was a hybrid.
Charon will be running s ski resort before an electric car even gets entered in LeMans.
Electric is a lovely idea. But it's not what's going to replace the gasoline engine.
I will respectfully disagree with you, and leave it at that.
Personally, I'm of the opinion we could free our dependency on foreign oil in five years if only idiots will stop screwing around and use biodeisel made from purified waste grease from fast food joints. Much less expensive than trying to make dedicated crops for it, and solves another large problem we have. An average fast food joint produces about a barrel of waste grease per day. Multiply by number of fast food joints, and you have suddenly out-produced OPEC in fuel for your trucking and ground shipping industry. For pennies on the dollar compared to petroleum based fuel. Heck, disposal of waste grease is a significant expense for fast food joints, you'll actually be *PAID* by your own SUPPLIERS. You can't get a better bottom line than that.
It's not a total solution, of course, since it won't affect civilian consumption much (there's a few diesel engine trucks out there, a few vans, but they are the vast minority) but at least a significant portion of fuel consumption will have switched to something self-maintainable.
