Pics of the new Tesla S-Model have been leaked. With an anticipated price tag of 50K and a potential 45-minute recharge time, will this finally kick-start a true replacement to the internal combustion engine? And if so, where will the electricity come from? What future is there for the fuel-cell vehicle, or will fuel cells remain stationary? Is that really it for hydrogen? [more inside]

How much is a penny worth today? Oh, about $0.0105465. Of course, it costs more than that to produce them. Is the penny worth keeping? The old copper penny had bactericidal qualities. You could drop a copper penny in a glass of wine to discern its nature. They were the subject of various high-school chemistry experiments. According to some, they were excellent conductors of luck. And the new zinc pennies? Their melting point is lower, and they don't have the same ring to them. Some people like them, others like to eat them. What are they good for? Not much. The time has come to abolish the penny.

I'm jaded. Nothing surprises me anymore. Except maybe zinc.
