quote: Realistically anybody buying a $106,000 car is going to garage it daily
quote: and in many cases, a heated garage.
quote: charge times and frequencies aren't ever going to improve that much.
quote: well, assuming charge technology doesn't change radically, physics.
quote: Now ofcourse, that's ad absurdum, but the problem still stands. If it takes a minute instead of a second, the powerplant doesn't blow untill the 181th car, but at the same time it's just as likely you'll get 180+ cars charging in a minute as it is getting 4 cars charging just a second.
quote: So here's our problem. Even if you manage to create some supercondutor hyper technology that's capable of delivering 306 million joules of electricity in just 1 second, you need to generate 306 million joules of energy in 1 second.
quote: And that's completly ignoring the issue of heat transfer and the fact not just the charging equipment but the powerlines from the powerplant all the way to the charging equipment have to be able to handle that many joules of electricity each second. Not just a second, they have to be constantly fed with electricity.
quote: let's say the average nuclear powerplant has an output of 1000 megawatt/hour, or 1 million kilowatt/hour, or 3,6 trillion joules in an hour. Hour has 3600 seconds, so 1 billion joules each second.
quote: Now, all the electricity we use is also generated right now, we have no form of long term mass storage of energy. Meaning shut off all powerplants in the US, the entire US goes dark.
quote: There is something called pumped hyrdo power. We (the US) have the ability to store around 5% of power for reuse later (we only get 4% back, so its a net loss in power
quote: Pumped Hydro generation capacity is not the same as storage capacity, and the latter is the important metric for making wind/solar usable.
quote: If this $100k car can't handle being driven at speeds alot of Americans drive on the highways it's a glorified golf cart.
quote: This evaluation was intended to demonstrate its practicality as a “normal use,” no-compromise car, as Tesla markets it. Now that Tesla is striving to be a mass-market automaker, it cannot realistically expect all 20,000 buyers a year (the Model S sales goal) to be electric-car acolytes who will plug in at every Walmart stop.
quote: This is why plugin hybrids are the future.
quote: I'd not count out fuel cell vehicles in a slightly longer timeframe though
quote: Perhaps just a minor hassle if you own a home, not so minor if you're cruising the highways or live in an apartment. To that end Elon has chosen his market more wisely than Nissan has.
quote: I don't get it... It seems all of the complaining and whining about electric is because it's electric?I don't see how people can even try to compare a purely electric vehicle with gasoline engines -- I mean, isn't it obvious by now that EVs are not gasoline? That buying an EV means you have to charge it regularily, drive it sensibly, and follow directions?I find it hard that an automotive journalist would be so pig headed as to treat this car as 'just another car'. Because it's clearly not.
