What is the predicted fuel burn of the 'Silent' Aircraft?

In addition to quiet, analysis suggests high fuel efficiency.


passenger miles per UK gallon
Mach * Lift/Drag
Toyota Prius Hybrid Car
~144 w/ 2 people
Boeing 777
103 - 121
Boeing 707
55 - 70

Emission predictions: total carbon and NOx

Low noise solution expected to have low pollutant emission
Low pollutant emission primarily a result of low aircraft fuel burn.

Chart showing

Total CO2 emission is 89.5 g per passenger-nm
Total NOX emission is 0.22 g per passenger-nm
