I think the cost is more the issue than the range - the range is already perfectly good for a commuter car, but pure electric cars cost about $10k more than their equivalent regular car. Even if it was completely free to charge the battery, which it's not, and even if the batteries didn't need replacing after not all that long, which they do, it would still take 8 years of daily 30 mile commutes to redeem that $10k in unpurchased gasoline. If the cost could be brought down to equal to the cost of a regular car, I would buy an EV right now. If the range went up and/or weight went down and/or charging time went down, and the cost stayed the same, I still wouldn't be interested.

Compressed air cars seem like a more feasible idea than hydrogen, at the current technology level. The hardware is cheap and the charger is basically a big compressor. But currently it's got about a 50 mile range running solo and production seems to have been shut down by problems with getting too cold from the rapid decompression. It would make a great hybrid with other tech that normally gets too hot! (But of course as soon as you go hybrid you're necessarily going more expensive - just compressed air driven is apparently cheaper to build than a regular engine.) All the companies that were touting compressed air cars have either vanished or removed all mention of it from their pages now, though, except this one. Much like Hydrogen, it has the problem of being relatively inefficient to charge - apparently 6 times less efficient than just charging a battery - but that's still cheaper than running on gas, and avoids the $10k up front cost and expensive battery-replacing of batteries.

Nomex posted:The problem with compressed air is you need a large tank and really high pressure to get any kind of meaningful power output. Big, high pressure tank = big, high pressure explosion in the case of an accident. quote:Out of curiosity, is there a premium that people would be willing to pay for a commuter-range EV over a gasoline equivalent? (Though I'm generally not inclined to buy a brand new vehicle anyway for similarly calculated reasons.) (Edit: I guess a little higher might be okay because the extra premium you add up front does kind of go in your 'car equity', which extra fuel costs doesn't.)

I suppose that explains why I saw a smart car in town and the license plate read "dumm".

dissss posted:Exactly - 34 is a lot better than 27. Points about it being able to fit in a smaller space, which factor I had largely ignored, are valid, but that doesn't really seem pertinent in most of America. Which is why, to bring the conversation back on topic, it doesn't seem at all surprising that they would make 'Smart' EVs that suck, to test the waters.

I wonder if such an advance would split the market in two - currently the range and price are both kind of at the sticking point, but if the battery tech gets double density at a lower price, then the target market could be split into daily commuters with the same range as current EVs but at a much lower price (and more efficient because lighter), and vehicles the same price as current EVs but with much longer range.

IOwnCalculus posted:No, but it does need them to work - the Prius CVT requires the electric motor to lock up in order for the gas engine to be able to put power down. And it's also much much less expensive to replace a relatively small hybrid battery bank when the time comes. So we can't really even begin to derive the practical running cost of a proper EV from the electric-part running cost of a hybrid.

IOwnCalculus posted:Yeah - if I could pay X for the car (at a rate comparable or less than an equivalent gasoline car), and pay Y per month for the battery forever (including exchange / repair as needed), I would jump on it in a heartbeat as long as the battery cost + electrical cost came out to less than my typical fuel cost in a month. (They claim they'll still have 70% capacity after 10 years, but I'll believe that when I see it on a car that hasn't been kept in an air conditioned room for its whole life. I've never owned a laptop battery that's had more than 30% capacity after 5 years, is this tech so different?)

Mortanis posted:If Tesla can do the battery swap in a reasonable amount of time, and the service is offered with their new charging stations they're rolling out, it goes from a luxury toy to a serious contender right quick. A reasonable amount of time for a swap would hopefully be 15 minutes or under, or about 3x the normal fill up time of gasoline, I think.

How severe of a crash are these cars getting into that it causes a fire? I mean, 3 out of 15000 cars catching fire in a year seems like a lot, but 3 out of 15000 cars getting into severe crashes also seems like a lot. I assume these accidents aren't just little rear-ending bumps or anything, because if they were then that aspect would be sensationalized too.

And to be on the side of the "we don't buy everyone else's gas" argument, that's nearly a couple of bucks a day, which still sounds cheap, but would you take a $500 pay cut per year for the option to plug your car in at work? (To be fair it shouldn't really be quite that much since paying $500 costs more due to payroll taxes, but still, the point is it's not nothing.)

Colonel Sanders posted:Yeah that author is a little too enthusiastic, but this guy must be onto something. . . What would work though, would be to put some bike pedals inside your EV so while you're driving you can be pedaling to help charge the battery. Include some extras for passengers too. Of course you'd have to move the gas and brake pedals onto the steering wheel to compensate for your feet being busy. With non-stop three very fit people pedaling for about 3 days you could get one full charge of a smaller Tesla battery, if the charging system is near-lossless!

If you had a coal powered generator and a gasoline powered generator, I'm pretty sure you could run the coal generator more cheaply.
