Simple!: Use Superconductive Elements!!!
I would promote the studies and experimentations of Superconduction Theories, then apply it to local - per occupancy power generation and systems.
Voltages and system types would be as described below under "Conventional" power systems.
Each occupancy would generate their own power, plus apply this to Superconductive circuit elements when possible.
Since that's simply a pipe dream / wishfull thinking, below is more understandable to actual human beings of planet earth - as opposed to mad quack scientists from other planets [like me
].
Here's my input for "Conventional" Power Systems
Residential:
200 VAC 1 phase 3 wire. Center tap grounded at transformer, plus grounded conductor from center tap brought to all services, bonded to local GES and all EGCs, but not an active circuit conductor.
Voltage to ground will be 100 VAC max.
Incandescent lighting would [should] be Quartz Halogen, or if normal Tungsten fillament / Argon filled envelopes are used, 4 position fillament supports.
This system might eliminate the problems revolving around common grounded conductors which are active in circuits [noise, open "neutrals", "hot grounds", overloaded commons, etc.].
For Commercial projects:
200Y VAC 3 phase 4 wire Wye [with 115 VAC to ground, but no L-G circuits used] for small occupancies and normal low voltage circuitry.
480Y277 VAC 3 phase 4 wire for larger occupancies, with SDS for 200 VAC systems.
For Industrial projects [low voltage only]:
200, 480 or 600 VAC 3 phase systems.
Grounding the system is still up in the air to me. Pros and Cons to the methods of either type [would like some input from others on this one! I have several ideas either way]. Systems point more towards the Ungrounded types - but will still be grounded at the transformer.
As for Frequency, I would lean towards 400Hz. The Skin Effect problems could be adjusted by designing conductors differently [multiple and separate tubular layers, Aluminum materials, Heat sinked exterior insulations, insulation with low Capacitive losses - possibly with an inert layer of pure water].
With higher Frequencies, the Efficencies [Q, core loss, etc.] of Induction type machines would benifit. Transformers, Reactor-Core Ballasts and Induction Motors fall in this category.
Transmission circuits will be effected the most. Multiple stacked parallel feeders would be one possible remedy - although the extremely large Induction problem with these "series" feeders would create choking and heat problems.
Possible to Transmit at 60Hz, then Invert to 400Hz - or Transmit as DC, then Invert to 400HZ. Either one will have Inverter losses and wastes [Transistor heat, Rectifier losses, etc.].
About the only system type I would really like to see changed would be the ones where untrained personnel can easilly mess with things! These would be Residential and small Commercial occupancies.
Frequencies would be better up higher for the end user, but remain low for transmission.
I still would like to dump everything in favor of Superconductive Elements!!! That's my idea of the ultimate systems!
