Calculation: ( Apology if my math is rusty)
Looking at the thread and facts given: 2.5 hours use per week, speed limit 20 MPH, quote 50 MPG , weight gallon of gas 6 pounds,
pounds of CO2 emitted per year 1474.2.
2.5 hours at 20 miles per hour =50 miles per week at 50 Miles per gallon= 1 gallon per week times 52 weeks per year= 52 gallons per year times 6 pounds per gallon=
312 pounds gas used per year.
Seems something is wrong. My math? Est of MPG (Even at 12 MPG) weight of gas used is less the Pounds of CO2 produced .
Must be something scientific like combustion of gas carbon used combines with more oxygen weight than carbon weight by a function of their molecular weight. Not worth discussing molecular weight.
It seems that we are all talking about some number that none of us question and then progress into our save the world discussions.
