I'm fairly sure he said there was no practical way to use a 2Tb storage device with USB 2.0... the shelves full of terabyte hard disks seem to contradict him.
It produces plain-text ASCII source code files. How is that lock-in? Why not use the best IDE/compiler for your code development? It's a free download.
eg. A really clever battery could have built in redundancy - spare cells which swap in if one fails. Battery maintenance could be performed at the charging stations if batteries reported failures.
Of course that makes the battery bigger and the main problem right now is that they're too big. Point is: Technical problems can be solved.
The bigger problem (judging by this thread) is the NIMBYs who precondition themselves to believing that they always get the dud battery, etc. when the real problem is their leaden right foot. One more thing to complain about around the water cooler...
The reason being that the amount of amperage and voltage necessary to charge a car in a reasonable amount of time is a lot more than what you want in a house
If you've got a few hours to charge them then you don't need special amperages/voltages. Standard houshold power is plenty.
The government doesn't actually have to do much: "You have six months to agree on a standard between yourselves. If you fail, we'll pick one company's proposal out of a hat at random."
Of course that's only in the sort of government I'd run... real life governments don't work that way. Sigh.
DC step up/down converters are very small/efficient these days. It would be easy to make a car which accepts any voltage from (eg.) 48-240V.
They won't do it of course. The same people who try to lock us into memory sticks and sell us $50 camera batteries are currently planning how to use this as a new way to screw consumers.
This is one place where government could actually step up and do something useful. Want to bet whether they will...?
Ultracapacitors currently only have about a tenth of the energy density of a battery and whether they can be improved more than two or three times while maintaining reasonable costs is far from certain.
Other than that, they're all good. Their efficiency is impressive (about 95% of electricity will end up in the motor, unlike batteries which can convert as much as 50% of it to heat during charging/discharging) and their working life makes them very attractive - current batteries aren't going to last more than a few years (much less if you're continually quick-charging them) and the e-waste millions of car batteries could produce down the line is huge.
Maybe we'll just have to get used to the idea of having a big chunk of the car space dedicated to the capacitor.
While it's a compelling solution, there are few obstacles to it becoming commonplace, for example:
As with plugs, you'd need a standard battery.
This is exactly the sort of thing that could be mandated by law.
(And given that cars are different shapes and sizes I think the only practical way is to have multiple smaller batteries per car instead of some monolithic "battery").
Given manufacturers want to compete on things such as range, a standard battery would remove one area where they could differentiate their product; making it unlikely.
You won't pay a fixed amount per charge, you'll pay by the Watt.
This lets them compete: "You want long life or regular?"
You'd need an accurate way to assess battery quality - or else you'll wind up trading good batteries for problematic ones.
Management of bad batteries will be built into the system (it has to be!) and you only have to keep them as long as it takes to get to the next charging station and swap for a different one.

I have 10TB of video in DVDs (yes I own that many).
Do try to keep up. You don't "own" a damn thing...
There's no terabyte-size USB hard drives in the shops where you live? Maybe you could come to Planet Earth where we're more advanced?
Something like that...
The video says they're waiting for the USB3.0 spec to be finalized before they can release a product.
If a 2TB version is available, why wait? Why not make a USB2.0 version of it?
Whatever, you'd think they'd be happy that there was a new way for their enemies to see/use an open source language.
Take your crapware...
You've not actually tried it, have you?
That's a bit like posting in a technical discussion without reading the article. It makes you look like an idiot.
It lets the atheists write code more conveniently.
Why would Python programmers be averse to Windows?
Some programmers are religious.
...lock you in... dangerous ...

What's really needed to push this along is something to make gasoline cars less attractive (usually this means fuel price).
Maybe we could hang some electrified chicken wire above the highways and put up an antenna to grab it - like the bumper cars at the fair.
Electricity *can* be produced sustainably. If we can be bothered to get of our backsides and do some work.
It's all just engineering.

Don't expect logic, science or reason to prevail with the NIMBYs...
there's ones that can be recharged, but would take a weak[sic] to charge using household voltages.
Really? I was under the impression that most electric car owners were charging their cars overnight for a few cents from a standard socket.
...for how much longer?
PS: There's this crazy idea called "sustainability" I heard about...

Having to find a charging station every 50 miles will still be a bummer...
This problem will sort itself out if all batteries are barcoded and tracked.
