Reasoning
Higher frequencies are desirable because transformers used for converting voltage can be both smaller and more efficient.
There are limiting factors, however. Electricity, when rectified, can cause a hum. 1 kHz would be like having the microwave beeping continuously. Higher frequencies can radiate like a radio transmitter. 400 Hz is a frequency that has in the past been used by trains and buses for running florescent lights.
At higher frequencies electricity tends to travel more towards the outside of the wire Skin Effect reducing efficiency and also establishes larger electric and magnetic fields causing the wire to behave as a radio antenna increasing interference to other users.

Pros
Clean-Sheet Design
This design is not tied to 19th century technological or political considerations.
Cons
Incompatible with Terrestrial Systems
Terrestrial products will require adaptation to work on a power grid using this specification.
Changes
There have been no changes to this specification
