Tesla CTO Talks Model S, Batteries and In-car Linux

angry tapir writes "The IDG News Service recently had a chance to speak to JB Straubel, chief technology officer for Tesla, about the Model S all-electric car, its design and technology, and his outlook on electric vehicle technology. He also shed a little light on the car's Linux-based software system."

    Hell, Europe is "closer" to the oil-producing countries and we're still paying £1.30 / 1.30 Euro a LITRE which is 6 $USD for a US gallon. And you know what? People still pay it, because there is still no viable alternative. Drive anywhere in Europe, it's all the same.

    I sat down, did lots of calculations and set my own limit a while back - at £2 per litre, that's $12 for a US gallon, I have to *start* reconsidering the amount of driving I do. Chances are that by the time it hits that, interest rates will have risen to match, salaries will have risen to match, fuel efficiencies will have risen to match, I'll need a new car anyway, and public transport prices will still be as ridiculous as they are now.

    And my reconsideration might just be "Well, nothing I can do about it" or even just "Actually, the relative value is still the same". It's not going to be "Oh, wow, I have to go out and spend tens of thousands on a new car with a new fuel, the money for which I'll have "saved" before it ends up as scrap metal." without some hugely drastic amount of physics being changed so that it's viable.

    Until anything approaching 60 mpg can be gotten out of a *SECONDHAND* car with ranges of 400-500 miles, where I can fuel up ANYWHERE without having to consult lists of stations and maps, where I can repair the car for no more than an ordinary one and where I can trade in that car for some decent percentage of the original price I paid, then every other technology is going to lose out.

    Hell, I did some maths the other day. If you add up the price of every car I've ever owned, every repair I've ever done (not including my own time), and fuel for several years, it *STILL* doesn't come to the price of one of the fancy hybrid cars that they want me to buy. Hell, for some models I wouldn't even get the second-hand price. In the face of such economics, it's no shock that the people who actually travel a lot aren't buying alternative fuel cars.

    For £300, I have a car that's lasted 4 years with me and required about £300 of repairs and parts in all that time. It burns £400 a month in petrol but I get 50mpg (UK gallon!). That's almost impossible to compete against with such technology. A complete engine replacement for my car? About £300 off the scrap heap or a grand or two for something "newer".

    When alternative fuel will honestly cost me more money than I've ever spent on my current car + fuel for a year before I even start driving it, it's hard to pitch those technologies. And replacing one hundred granny's cars who do 10 miles a month is pointless if you could replace just one heavy road user with a decent car.

    Hell, I don't even care about speed, I'd poodle along in the slow lane quite happily, so long as it was motorway-capable (which means at least 60mph by law in my country). But you just CANNOT get close to anything the petrol offers at the moment, and petrol can quite literally double in price and STILL it would be more worthwhile. It would have to literally quadruple or more in price to actually price myself out of using it, and then things like LPG conversion (was quoted £800 for a full conversion last year) would probably get me another doubling of price before I was priced out again.

    Petrol is amazingly cheap for what it gives you compared to EVERYTHING else that's at the cutting edge of research.

    This is the opposite of trickle down economics. Trickle down says that you should give money to rich people first, so that eventually it finds its way to poorer people.

    Tesla's model is to take money from rich people first, to fund research that eventually helps poorer people too. That sounds a lot more like a progressive stance when put that way, right?

    I traded my hotrod (2010 camaro SS) in for a Volt, and haven't looked back. Even if I had the money for a model S tesla, I can't have one yet - that's the real challenge Elon's outfit has - ramping up production before the bigger base loses interest.
    .

    FWIW, here in VA, it takes about 200 sq feet of high efficiency solar to charge the Volt once a day. That's around 45 miles worth of range, which gets more than 80% of my own driving done, even though it's a 27 mile roundtrip to the nearest general store for beer/munchies. I can get to the nearest town, do all my errands, come back, still have a little under half my range left. It works for me. Not as sexy as the Tesla, but it's no slouch either and does get a lot of favourable attention.
    .

    Sure is nice to have that unlimited range due to also having a gasoline engine, tuned just for this use so it can be more efficient than just about any other out there. 40 mpg from a 3800 lb car ain't shabby. I don't use it much, but what it does for you is remove worry if you're going to be pushing the battery only range.
    .

    For once, GM really leapfrogged everyone else. The GM haters are out in force to dis this car, but that kinda tells you who isn't doing much critical thinking and saves you from time wasted thinking they are OK (kinda like hank hill's comment about body piercing - you know right off someone "just ain't right").
    .

    I wish Tesla every success, they've "Bet the farm" and gotten a heck of a lot of stuff right. But now they need to transition from a design-only outfit to a major manufacturer - not trivial in real life. Go Elon!

    You are completely wrong.

    Tesla isnt a government entity taking money against people's will. They are a company selling a premium product to wealthy people. They are reinvesting that money to refine their product and make more money. If they are successful this will have an economic ripple effect that will produce more jobs. The government has been supporting this by taking money from others to provide loans to the company and tax incentives to the wealthy buyers. If that isn't trickle-down economics I dont know what is.

    Tesla will produce an inexpensive car when (1) it can be done profitably and (2) they want to be in the business of dealing with many low-margin customers instead of few high-margin ones.
