Still increases air resistance. It gets hit by air, and that pushes it back into the fuselage.

Larger aircraft commonly have a ram air turbine (RAT) or Air Driven Generator (ADG) to provide some electrical power and hydraulics in certain emergency situations.

Still delivers a percent or two penalty to fuel burn, and the tiny little generator doesn't even come remotely close to making up for that.

It's not clear, but I think they were referring to the version 1 Pi - the newer ones are much much much faster.

Being an SUV, it'll weigh 50% more than necessary. That outweighs almost any other sustainability considerations.

Musk said last week: “I disagree with the idea of unions. I just don’t like anything which creates a lords-and-peasants kind of thing.”

Isn't he the world's richest person currently?
