Oct 27th 2010 3:31AM Enhancing flavor to calorie ratio does not make food more healthy to consume; research on the psychological impact of flavor-calorie associations suggests that the more flavor per calorie, the more the food increases the appetite of the eater. This is why the proliferation of diet sodas hasn't done a thing to reduce our obesity epidemic. If anything, it has only gotten worse.
There's a book called "The Shangri-La Diet" that talks about this effect. Scientific studies suggest that flavor-calorie associations increase a person's set-point (the weight their body wants to be at). Conversely, bypassing any flavor-calorie association seems to be a surprisingly easy drug-free way to get the body to lose weight by making it want to be at a lower weight. I recommend the book for insight into the unconscious sensory and psychological aspects of weight control, if for nothing else.

CO2 doesn't harm the ozone layer. You're confusing CO2 with CFCs (chlorofluorocarbons).

May 18th 2010 6:24AM I read that Elon Musk screwed Martin Eberhard (one of the founders) out of the company.
If Musk is the royal prick Eberhard claims him to be, this may just be him reaping what he sowed.
Feb 17th 2010 5:47AM This is not entirely true; it is actually a matter of scale. At the extremely large scale, vertical axis wind turbines (VAWTs) are impractical, and are much more material intensive than horizontal axis wind turbines (HAWTs), but they have been proven extremely practical at the medium scale and at the small scale for several reasons:
1) They can take wind from any direction without being steered into the wind. A horizontal wind turbine resists being steered when its rotor is rotating because the angular momentum of the rotor tends to keep it pointed in the same direction. (This is the same reason rifle bullets are spun as they travel down the barrel to increase accuracy and group tightness.) In many medium scale applications, especially near roads, the wind direction changes too much for HAWTs.
2) VAWTs that generate torque by semi-drag/semi-lift such as Savonius turbines are self-starting in low winds. The high efficiency HAWTs must be spun up to speed before they can draw any power out of the wind.
3) small VAWTs are dominated by Savonius turbines, which are silent and don't kill birds like lift based HAWTs.
Examples of medium scale VAWTs in action:
The Quiet Revolution turbine, in use in a city environment where HAWTs are impractical:
An example of a silent, non-bird killing Savonius turbine:
Here's a street light that uses a small Savonius turbine in combination with small solar panels:
