While I applaud their efforts I can't help thinking about those planes that fly about. Try this;
Airbus A321. Range 5600 Km's
Fuel capacity 24,050 Litres (STD)
Fuel Capacity 30,030 Litres (Long Range)
Now if we do some arithmetic we get
5600.00 KM's
23000.00 Litres (this is an estimate only of the Fuel used.)
410.71 litres/100 km
0.69 miles per gallon. Yes that's right
Makes the old falcon seem positively frugal and all this to transport a maximum of 220 people.
Think of the number of flights globally per day and the amount of fuel used, makes the mind boggle.
