As a pilot student, I would love to fly an Airbus 380. So far I’ve only flown it utilizing my flight simulator download program – flightsimulatordownloadd.org Can’t wait to fly the actual plane.

The electric motors will enable the plane to not have a hydraulic system, for one thing. Hydraulic liquid, tanks, lines, valves, etc., etc. are heavy and maintenance intesive. An all-electric plane with no hydraulics will help improve efficiency…the -787 is most of the way there, already.
Current planes use hydraulics for landing gear movement, braking, steering, and power for much of the flight controls, among other things.

The key thing is the lack of contrails meant more sunshine by day, and more radiative cooling by night, just as with really clear weather you get a bigger difference between high and low than you do with cloudy weather.

So the weight of the electric motors is offset how?!? I could see “painting” the wingtops and upper fuselage with lightweight solar cells. Once above the clouds additional power might be significant. (just dreaming…

If you consider the other activities related to air-travel, that number would probably increase substantially as well. Also, the writer must be incredibly opimtistic if he thinks the world will have enough liquid fuels 50 years from now to sustain a tripleing of current air-traffic volumes. In 50 years, most likey the only people flying will be the very wealthy or those on goverment or critical tasks.
