Oh really? How's that been working out for you so far? How many - even of that self-selected few - actually compile their mobile OS from hand-verified source, pray tell?
Actually, while its had for people to grasp a market of a billion people, its even more staggeringly harder to grasp the idea of a non-market of 3.5 billion people.
Keep in mind that the median worldwide household income is under $10K/yr...
I'd push greater commitment to keeping the essential components of the system under FOSS licenses onto the head of that list.
If this really can work for ~3.5 billion people who currently don't have a decent mobile OS (a claim about which I remain skeptical), I guarantee you that at least 3.49 billion of them won't give a damn whether its FOSS or not. Of the remainder, most surely won't care whether its GPL, BSD, or PirateBay licensed.
How 'bout a beefy UPS? That allows the simple "continuous power" scenarios to be considered again, and is far cheaper than staffing a desk.
Badging in a door adds approximately half a second. What precisely are you envisioning that would be fine if stopped in 1 minute (aggressive timespan of notification to someone outside the room to them arriving and taking an action) but complete shite if stopped in 1 minute 1/2 second?
Because there's a difference between attracting users and monetizing them?
Unfortunately, it is already wired for 200 amp service for a reason. Many American homes with dryer, range, electric AC/heat, and electric hot water cannot take another 50 amp load without the real possibility of exceeding 200 amps. Having a 200 amp service is no guarantee your ready to add Tesla charging.
So set your charger to run between midnight and 6am - easy. Or some other time when you're unlikely to be running the dryer, cooking, cooling your house, and heating lots of water all at the same time.
The stock was up as high as 17%, and closed up just under 14% (+$30 on the day to $248). With Morgan Stanley estimating a $320 price there is probably significant growth left, It seems they will have no problem funding that 5 to 7 Billion dollar battery plant.
You realize that unless they do another offering, are are buying another company with stock, the rise of fall of the price in the secondary market has absolutely no affect whatsoever on Tesla's ability to build a plant?
Assuming that you see nothing wrong with comparing a Civic to a BMW 7-series purely on cost either, then your comparison is valid. Otherwise people might think that it was a wee bit skewed.
Still only barely competitive with a carpool, which is a shame - though again, to be fair roads are also subsidized somewhat.
Urban roads cost somewhere in the neighborhood of $15 million per lane mile (and up from there). Also remember that most roads have at least two lanes. Even adding a lane to an existing road can cost ~$5 million per mile. Commuter rail is usually dirt cheap in comparison to road expansion, but since maintenance and construction costs are so much less they have far fewer voices during bond elections than the concrete guys do.
As long as you consider "no compromise" to mean paying a hundred grand and getting less than 250 miles of range and having to wait extended periods of time to recharge, with the distinct possibility of not having a Supercharger station available before the power runs out. It's a nice car, but it's still not terribly practical for most people.
Most people - especially those in the $80K car market - fly somewhere when they need to go over 300 miles in a single trip without ending up back where they started.
Even their "green" credentials are on very thin ice, what with all those batteries full of Lithium and rare earths that travel all around the world after having been mined and extracted with horrifically polutting methods.
As opposed to oil, which is often extracted with polluting methods then shipped by boat around the world to be refined before being shipped again to its destination? And that happens for every tank, not just for manufacture.
Your calculation misses some crucial points.
Refinery energy losses (typically
Transmission costs (varies by location since most oil is delivered by boat and gasoline is delivered by truck)
Also energy needed to manufacture the engine, refine the steel, etc, pp.
Its telling that the full lifecycle energy cost of a Tesla's power is still better than only one component of an ICE vehicle, don't you think?
It takes very few emissions to send something twice around the world these days. Don't make the mistake of looking at the absolute carbon cost of a modern vessel vs. a single piece of its cargo. A modern container ship can transport somewhere around 18 million cubic feet of cargo from China to the US using ~4,800 tons of fuel (1.3 million gallons). So a gallon of fuel can move approximately 14 cubic feet of stuff from the US to China (or back).
