3rd age of aviation

1st age: Propellor

2nd age: Jets

3rd age: Electric motors.

This is an interesting Munroe visit to Joby, a company making small light weight aircraft for transporting people. The technology looks to be well advanced & competent (39:25):

If this works & is as quiet as shown, there are countless applications for it all over the world, both for moving people & goods.

If electric motors are the answer, then probably airships are too.

You will be limited in both speed and range. Almost certainly altitude too

I wouldn't fancy a transatlantic flight using them

There are a number of issues with airships. They are generally large and troubled by winds, limited in velocity and need infra structure for the gas, usually helium nowadays.

Electric motors need only a charging supply for the batteries and can be small and highly manoeuvrable.

As of now the energy density of batteries is a trouble for transatlantic flights and propellor drives are slow compared to jets. There are ideas for electrical ion drives, but as far as I know they are not currently practical.

The sort of machines that are shown in the video are suitable for airport to city and city to city type of short range flights, competing with rail and road transport. This is a potentially large market.
