IIRC, Matt Yglesias and Paul Krugman have both been arguing that an inflation target of 4% to 5% instead of the current 2% or so, and perhaps also another round of Congress passing an economic stimulus package, would help a lot with the ove

Which of efficiency or price/watt matters more depends on the application. For example, I believe something like 4 m^2, 40% efficient, 8 hours of charging is enough to get electricity to drive a Tesla something like 30-40 miles. (In p

If those are 1,5000 professional tax preparers who each perpare taxes for many taxpayers, it might make sense. Going after only high income citizens might also create a reasonable situation where $133k/taxpayer in their biased sample s

On the other hand, if Tesla continues to raise funds every six months in a manner similar to the recent secondary offering, buying and holding the stock for a long time will probably not turn out to be the fantastic deal for shareholders th

The dealers claim they are protecting consumers from the automakers. I keep wondering where I can find an example of a person who clearly is not an owner/employee/etc of a dealer who genuinely feels protected. There are probably far more p

Tesla strikes me as having a lot more growth potential than any other publicly traded company I'm aware of, if things go well for Tesla. I certainly think its value is based upon future earnings potential, and not current revenue.

With the level of enthusiasm Consumer Reports showed for the Model S, and the lack of interest in building electric cars on the part of all the legacy automakers, I doubt there is going to be enough production capacity for 200+ mile range e
