What will be the miracle MPG of the future ?

Good evening !

I mean Burt Rutan did 140 mpg per passenger already in 1975 with Vari Ez and newest GFC winners get 330 PMPG with the Pipistrel G4.

I estimate in 2018 the figure is 1432 PMPG ( passenger miler per gallon ).

It needs the 6 seater gliderlike aeroplane to have muscle power option for 5 people ( pilot has no obligation to pedal while steering ) and 37 m2 of new kinda efficient solar power panel and a 20 hp sustainer engine for take off and nite flying.

See my blog for more info ( below the link ).

Dave Morss told me the G4 has now over 400 pmpg.

1432 pmpg is still distant dream but doable..I am sure.

This is interesting...1 hp motorplane in 1932 ?
