If a human brain had wheels, do you think it could get good gas mileage?

Question

It would be low weight and also have a small carbon footprint.

Answer 1

Most brains do a lot of turning round in circles, so would get very poor mileage. It takes a well defined route to get good economy.

Answer 2

Yes actually.  Human beings, an living organisms in general are incredibly efficient in terms of energy.  That's why after exercising all day, you can steal eat a cheeseburger and NOT lose any weight for the day.  It takes very little to keep out bodies running.  In comparison a car needs gallons of gas to run on (and yes a car is much more powerful than we are) but what you don't realize is that gasoline is EXTREMELY high in calories (yes; everything has calories, even if you can't eat it- calories just refer the energy in something).  In fact a mere cup of gasoline has like 10,000 or so calories.  So putting 10 gallons in your car is would be like you eating a few hundred pizzas.
