Petrol produces a mass of CO2 greater than itself when burnt.

How can 6 pounds of gasoline create 19 pounds of Carbon dioxide?

It seems impossible that a gallon of gasoline, which weighs about 6.3 pounds, could produce 20 pounds of carbon dioxide (CO2) when burned. However, most of the weight of the CO2 doesn’t come from the gasoline itself, but the oxygen in the air.

When gasoline burns, the carbon and hydrogen separate. The hydrogen combines with oxygen to form water (H2O), and carbon combines with oxygen to form carbon dioxide (CO2).

A carbon atom has a weight of 12, and each oxygen atom has a weight of 16, giving each single molecule of CO2 an atomic weight of 44 (12 from carbon and 32 from oxygen).

Therefore, to calculate the amount of CO2 produced from a gallon of gasoline, the weight of the carbon in the gasoline is multiplied by 44/12 or 3.7.

Since gasoline is about 87% carbon and 13% hydrogen by weight, the carbon in a gallon of gasoline weighs 5.5 pounds (6.3 lbs. x .87).

We can then multiply the weight of the carbon (5.5 pounds) by 3.7, which equals 20 pounds of CO2!

Passenger vehicles per year

Passenger vehicles are defined as 2-axle 4-tire vehicles, including passenger cars, vans, pickup trucks, and sport/utility vehicles.

In 2007, the weighted average combined fuel economy of cars and light trucks combined was 20.4 miles per gallon (FHWA 2008). The average vehicle miles traveled in 2007 was 11,720 miles per year.

In 2007, the ratio of carbon dioxide emissions to total emissions (including carbon dioxide, methane, and nitrous oxide, all expressed as carbon dioxide equivalents) for passenger vehicles was 0.977 (EPA 2009).

The amount of carbon dioxide emitted per gallon of motor gasoline burned is 8.92*10-3 metric tons, as calculated in the “Gallons of gasoline consumed” section.

To determine annual greenhouse gas emissions per passenger vehicle, the following methodology was used: vehicle miles traveled (VMT) was divided by average gas mileage to determine gallons of gasoline consumed per vehicle per year. Gallons of gasoline consumed was multiplied by carbon dioxide per gallon of gasoline to determine carbon dioxide emitted per vehicle per year. Carbon dioxide emissions were then divided by the ratio of carbon dioxide emissions to total vehicle greenhouse gas emissions to account for vehicle methane and nitrous oxide emissions.

Calculation

Note: Due to rounding, performing the calculations given in the equations below may not return the exact results shown.

8.92*10-3 metric tons CO2/gallon gasoline * 11,720 VMT car/truck average * 1/20.4 miles per gallon car/truck average * 1 CO2, CH4, and N2O/0.977 CO2 = 5.1 metric tons CO2E /vehicle/year

Equivalent calculation in Australian units of measure will be added by TeamGlobeus shortly.

Here are a few initial compromizes;

– Can’t, and so won’t, be zero emission to start with, this is a long term plan.

– Systems will be very lean in the beginning.

– Member site and management are the first real costs.  May require small backing/loan.

 

On positive side;

– Have registered a domain and have splash page up.

– Sorting out system architecture.

– Have solid pre-start plan/process.

– Meetings with web devs lined up.

Face it; you’re hooked. It’s your uncontrollable urge to check for email notifications on your phone. It’s your compulsion to visit Facebook or Twitter for just a few minutes, but somehow find yourself still scrolling after an hour. It’s the fact that if I recommended a book to purchase, your mind would flash “Amazon” like a gaudy neon sign. If habits are defined as repeated and automatic behaviors, then technology has wired your brain so you behave exactly the way it wants you to.

Project Update

February 21, 2012 Leave a comment

Current areas of exploration:

Presently engaging with advertising company in related field to identify and set revenue/pricing levels.

Engaging with 2 developers for web-app/portal for users and sponsors.  Also getting advice on field infrastructure.

Have solid prices on transportation costs with a premium service provider.

Hoping to bring a limited partner onto the project (in discussion).

 

Considering the following (post financial analysis);

– Business name and registration (ACN/ABN).

– Approaching local shopping location/corporation for partnership/parking access for members.

– Small business loan or, capital raising through ASSOB.

 

WORK IN PROGRESS
