1. We can run on multiple stored fuels: glycogen, fat. A hybrid car can run on gasoline, battery power and supercapacitor power. 2. We can run on fuel obtained at any moment: sugar. A hybrid car could in theory run on solar power in the form of flexible panels on the car's surface. 3. Our bodies are always storing power for later use-- into glycogen, into fat. A hybrid car is often storing it into the supercapacitor and the batteries. Given this, why would anyone be a hybrid-hater? New bumper sticker: The human body works like a hybrid car.
the human body is full of factory defects, my Prius has been more reliable and cheaper to run .. I know I cant go 45 mile for under three bucks
... but if I could somehow recover and store the kinetic energy from running down hill, and have it available to help me up a later one, it'd be really cool. -Chap
In a way they do. When you fill up the gas tank they put on extra weight. They just have no capacity for unsightly blubber. Also that fat may be ugly but it has a practical use--it's stored energy that powers you. And there *are* cars that can run off of animal grease---they call it biodiesel. Perhaps a European Prius that runs on diesel could also run off biodiesel. You bought a prius and you're not prepared to think outside the box? Come on... Creating you didn't require a steel mill, 300 pounds of plastic, semiconductors for computers etc. Humans are more evolved. They can self-repair after all. There are surely many hidden environmental costs to making a prius.... Costs that if we assessed them correctly would put the price well above what we pay.
