Electric Airplanes for the Future!

The video discusses the high fuel consumption of airplanes, particularly the Boeing 747, which uses about 1 gallon of fuel per second. NASA, Google, and the Comparative Aircraft Flight Efficiency Foundation collaborated to address this issue, leading to the Green Flight Challenge. The challenge required aircraft to travel 200 miles in under two hours using less than one gallon of fuel per occupant or its electric equivalent. The winning aircraft, the Pipistrelle Taurus G4, achieved remarkable efficiency, using the equivalent of half a gallon of fuel per occupant and demonstrating four times the efficiency of a Boeing 747.

What was the name of the winning aircraft in the Green Flight Challenge and what was its efficiency?

How does the efficiency of the Pipistrelle Taurus G4 compare to that of a Boeing 747?
