Update: Fisker Karma Electric Car Gets Worse Mileage Than an SUV...

by Warren Meyer

The Fisker Karma electric car, developed mainly with your tax money so that a bunch of rich VC’s wouldn’t have to risk any real money, has rolled out with an nominal EPA MPGe of 52 in all electric mode (we will ignore the gasoline engine for this analysis).

Not bad?  Unfortunately, it’s a sham.  This figure is calculated using the grossly flawed EPA process that substantially underestimates the amount of fossil fuels required to power the electric car, as I showed in great depth in an earlier Forbes.com article.  In short, the EPA methodology leaves out, among other things, the conversion efficiency in generating the electricity from fossil fuels in the first place [by assuming perfect conversion of the potential energy in the fuel to electricity, the EPA is actually breaking the 2nd law of thermodynamics].

In the Clinton administration, the Department of Energy (DOE) created a far superior well to wheels MPGe metric that honestly compares the typical fossil fuel use of an electric vs. gasoline car, using real-world power plant efficiencies and fuel mixes to figure out how much fuel is used to produce the electricity that goes into the electric car.

As I calculated in my earlier Forbes article, one needs to multiply the EPA MPGe by .365 to get a number that truly compares fossil fuel use of an electric car with a traditional gasoline engine car on an apples to apples basis.  In the case of the Fisker Karma, we get a true MPGe of 19.  This makes it worse than even the city rating of a Ford Explorer SUV.

In the Blink of Bird’s Eye, a Model for Quantum Navigation

European robins may maintain quantum entanglement in their eyes a full 20 microseconds longer than the best laboratory systems, say physicists investigating how birds may use quantum effects to “see” Earth’s magnetic field.

Quantum entanglement is a state where electrons are spatially separated, but able to affect one another. It’s been proposed that birds’ eyes contain entanglement-based compasses.

Conclusive proof doesn’t yet exist, but multiple lines of evidence suggest it. Findings like this one underscore just how sophisticated those compasses may be.

“How can a living system have evolved to protect a quantum state as well — no, better — than we can do in the lab with these exotic molecules?” asked quantum physicist Simon Benjamin of Oxford University and the National University of Singapore, a co-author of the new study. “That really is an amazing thing.”

Many animals — including not only birds, but some mammals, fish, reptiles, even crustaceans and insects — navigate by sensing the direction of Earth’s magnetic field. Physicist Klaus Schulten of the University of Illinois at Urbana-Champaign proposed in the late 1970s that bird navigation relied on some geomagnetically sensitive, as-yet-unknown biochemical reaction taking place in their eyes.

South Dakota To Make Gun Ownership Mandatory

Five South Dakota lawmakers have introduced legislation that would require any adult 21 or older to buy a firearm “sufficient to provide for their ordinary self-defense.”

The bill, which would take effect Jan. 1, 2012, would give people six months to acquire a firearm after turning 21. The provision does not apply to people who are barred from owning a firearm. Nor does the measure specify what type of firearm. Instead, residents would pick one “suitable to their temperament, physical capacity, and preference.”

The measure is known as an act “to provide for an individual mandate to adult citizens to provide for the self defense of themselves and others.”
