The U.S. Government wont answer that question. Boeing says the 747-200 that it is based on uses 5 gallons per mile
CO2 is not used in or as an aircraft fuel.
Yes
All US Presidents use Air Force 1.
They use the wrong kind of energy and they use too much of it. That's why other batteries are way better. One, they hardly use 6% as much as chemical fuel cells. Two, the chemical fuel cells pollute the air too.
none unless it is flying
You can use clear tube for a fuel line but only when using a system that is fed by gravity. Any other type of fuel system will have too much pressure for the tubing to handle.
alot
No one answer. It depends on the fuel mileage for THAT car, and how many miles it is driven.
High fuel consumption
About 100 gallons of diesel fuel.
I use a 1-gallon and a 2-gallon plastic gas can (one for regular fuel and one for fuel/oil mix) to store my fuel and I have never had a problem with the fuel going bad. However, it is known that fuel will get stale after 30 days - that may be where your problem lies. Get a smaller container if you don't use very much fuel in a 30-day period. Or, you might try adding a fuel stabilizer product with your fuel.
If the car has a "Carb" you can use rubber line....however, you have to be extremely careful with routing the rubber fuel line as rubber line is prone to rubbing a hole through it which can lead to a fire. Also you have to use fuel line, NOT vacumn hose. Do NOT use rubber hose on a fuel injected car as the fuel pressuse is much higher.
