Actually a large percentage of electric vehicles are coal powered. Electric is only good for the environment if your electric power comes from non-fossil fuel sources.
That argument is ten years out-of-date. Nowadays, the largest percentage of electric vehicles are natural-gas powered.
This is the same cycle that Tesla's been through with the S and X. They burn cash until production ramps up, then they actually make money for a quarter before the plow it all back into R&D for the next vehicle. They have a plan to reach 5000 week, and a goal of over 25% margin. They will be fine.
I think it's insane to say something like Facebook should not exist because they can know everything about us.
The things that they know, ANYONE could know if they did what Facebook did.
What Mr. Stallman is saying is that we should enact laws against collecting all of this personal information. And if the result of those laws is that companies like Facebook go out of business because they can no longer be profitable without that capability, then they should be allowed to fail and no longer exist.
It's lagging because the legacy automakers are still creating EVs that look like econo-boxes, and nobody wants to pay luxury-car prices to end up with a Nissan Versa competitor. Tesla doesn't make econo-boxes, and the sales of the S and X are actually greater than other popular combustion vehicles in their class.
Rei is talking about each car sold turning a profit, and that is correct. The cars are revenue positive, with margins that other automakers are jealous of.
You're talking about the profitability of the entire company. And you're conveniently ignoring the fact that Tesla is in growth mode. They're buying infrastructure for building a half-million cars per year. They're designing several new vehicles to bring to production in the next two years (A semi-truck, a new roadster, a small SUV, and a pickup truck, to name just a few). I don't expect the company itself to turn a profit until they've filled out their product portfolio.
Tom 7 (suckerpinch on YouTube) wrote a program that teaches itself to play SNES games. He wrote a paper for SIGBOVIK 2013 on the subject, and also created a surprisingly entertaining 16-minute video explaining how it works and showing some of the outcomes. Throughout this video, Tom points out some "strange choices" (i.e. "cheats") that the computer discovers and makes use of in Super Mario Bros, Pac-Man, and Bubble Bobble.
Well, I think any natural resource extraction on Mars would be - the output would be for Mars. It definitely wouldn't make sense to transport Mars stuff 200 million miles back to Earth. Honestly, if you had like crack-cocaine on Mars, in like prepackaged pallets, it still wouldn't make sense to transport it back here. It'll be good times for the Martians, but not back here. Resources would be for a colony to use.
Unlike a combustion vehicle, an electric vehicle doesn't use a whole lot more energy when accelerating quickly vs. accelerating slowly (given the same final velocity). Also, regenerative braking would allow the Roadster to recover a good portion of that expended energy. The Roadster has a huge battery, giving it a 600 mile range at normal highway speeds. The Roadster is going to end up needing *fewer* breaks than the combustion vehicles.
Yeah, that was a problem with Tesla's luxury family sedan. We're talking about the upcoming Roadster. It's not going to have that issue. They'll be sure to give that thing enough cooling ability to track it all day long.
There were no 10 foot swells - the sea was as calm as could be in that "test". So the jetski could operate at full speed.
The person in trouble was easily visible from shore. In 10 foot swells, a drone will have an easier time spotting a person in trouble far from shore.
The drone was stationed at the beach, instead of at the lifeguard tower. So someone had to run from the tower to the drone first. That's silly.
The ideal situation would be to have a drone for spotting, with the capability to drop a flotation device, and have the jetski driver make use of the drone to determine where to go in rough seas.
Not exactly true, they have been trying to get others to "License" their charging standard.
Citation needed.
There is evidence that this is not at all true. There is a company selling a JDapter Stub, which allows other EVs to charge at Tesla destination chargers. And they appear to still be in business.
For the supercharger network, Tesla (rightfully) insists that any other company that wants to participate must help pay for the cost of the network.
Oh please, Go is just Yet Another Programming Language which wasn't really necessary, but purely because some devs just didn't like other languages (or didn't know how to handle them properly).
Some devs? Really? And other people mark this as insightful?
Do your homework people. The "some devs" who developed Go include:
Ken Thompson. Perhaps you've heard of him? He invented Unix. He invented B, the immediate predecessor to C.
Rob Pike, another Bell Labs alum. He helped develop Unix, Plan 9, UTF-8, and X (the graphic system protocol).
They had a specific goal in mind when they developed Go. They wanted to make systems development faster and easier, and able to scale to the kinds of systems used at Google. This isn't just defining a new syntax for the hell of it. A lot of thought was put into reducing compile times. A lot of thought was put into the tooling. The edit-compile-debug cycle is so much quicker with Go than for any other language. It really does help speed up development.
If that is really the case, when why not compute the hash locally on the user's machine, and upload only the hash?
Because then it becomes much easier to reverse-engineer Facebook's hashing algorithm, allowing an attacker to make small changes to an image to result in a different hash.
Will self-driving cars still be reliable when the street is covered in snow, so it can't see the lines?
Eventually, sure. Several companies (Google included) have very accurate maps of all public roads. They'll eventually be able to use information about what *can* be seen in the snow (sign posts, guard rails, etc), map those to their road maps, and use that information to infer the location of all known road markings.
You know, much like people do, except they'll be referring to accurate maps instead of memory.
Or when it snows so much that the snow sticks to traffic signs making them unreadable?
Again, they'll have recorded every inch of public roads, and will already know what every sign says long before the self-driving car ever drives on that road.
How about stopping at a traffic light when the street is covered in black ice?
Better than a human. It will receive reports of issues along the route it's taking, including reports of ice.
And if it's the first vehicle to encounter the ice? Well it won't be any worse than a human, will it? Next straw man: "but the human will know that the intersection always gets bad during a snowfall". Again, the computers will (eventually) have access to that same kind of historical information and will adjust.
It only takes me about 5 minutes to fill up at a gas station. That will give my car 300-400 miles of additional range.
Supercharging a Tesla takes 20-30 minutes, and will only get you about 200 miles of additional range.
We're not there yet. Elon Musk has hinted at much faster superchargers in the near future, but right now it's not comparable. It makes long distance travel *possible*, but it's not yet as convenient as in a combustion vehicle.
I currently pay $180/mo. for a family plan of 7 lines on T-mobile. Unlimited everything on every line, including high-speed data. They also give $10/mo back for each line that uses less than 2GB of data in any month. That seems pretty damn cheap.
Shitty : fails to detect enormous object right in front of the car, when one of the stated purposes of the system is to detect objects in front of the car.
Half-assed : the vendor of the hardware disassociates itself from Tesla stating the tech is not being correctly implemented.
Here's the TLDR version:
- Autopilot controls speed & steering, keeping the car in the lane.
- The Automatic Emergency Braking (AEB) feature is the technology that should have stopped the car to prevent the accident.
- Tesla was using Mobileye's AEB implementation.
Lots of other companies are using Mobileye's AEB as well. It was only an issue in the Tesla because the driver was paying no attention to the road. In other vehicles, the driver would have hit the brake themselves when they saw the big truck in front of them.
The $422m figure is for a Delta Heavy launch, which makes the comparison with the Falcon 9 laughable
It's actually a valid comparison. The latest versions of the Falcon 9 (full-thrust) can deliver 50,300 lb to LEO and 18,300 lb to GTO (ref)
The Delta IV Heavy can deliver 63,470 lb to LEO and 31,350 lb to GTO (ref).
- it should be compared with a Falcon Heavy launch, which SpaceX ain't giving launch cost figures for yet.
The Falcon Heavy is going to be in a much higher league - 140,700 lb to LEO and 58,900 lb to GTO (ref). And SpaceX has been providing launch costs for the Falcon Heavy for a quite a while ($90M). Falcon Heavy is going steal the little bit of market that remains for the Delta IV Heavy.

Tesla has already stated (at the 2018 annual shareholders meeting) that they're close to an agreement to put the next factory in China.
Tesla's stock is down 12% in the last 12 months in a strongly up market.
Ah, yes. Let's take an arbitrary time period and build an argument around that. Let me try:
Tesla's stock is up 10% in the last 2 months...
Tesla's stock is up 48% in the last 24 months...

To find out, you mustache how much it costs.

Problems will start when countries start exporting natural resources back to earth...
That's never going to happen. Elon covered this in a pretty easy to understand fashion:
Elon Musk: Natural Resources on Mars (51 seconds)
Well, I think any natural resource extraction on Mars would be - the output would be for Mars. It definitely wouldn't make sense to transport Mars stuff 200 million miles back to Earth. Honestly, if you had like crack-cocaine on Mars, in like prepackaged pallets, it still wouldn't make sense to transport it back here. It'll be good times for the Martians, but not back here.

Hey Tesla, how about you STOP calling it autopilot. It's NOT autopilot.
Hey GM, how about you STOP calling it cruise control. It is NOT cruise control. Call it "Speed Assist".
Seriously, this is one of more dumb arguments against the name autopilot I've heard. It is almost exactly equivalent to a plane's autopilot system.
