A single wire electrical energy transmission....

[Gopalkrishna]

Single wire electrical energy transmission without a (ground ) return path...

A new way of transmitting electrical energy from a floating totem pole node to almost 500 miles away end point of propagation...
My totem pole electric charge supply is made of a high voltage battery and two switches wired in series like break before make kind..from positive to negative terminal termed as S1 and S2.But they are complimentary in action.The Totem in between two switches is connected to a 500 mile long straight conductor..in view of power transmission that long...
When the high voltage positive terminal is made active by closing S1 and automatically S2 is open ...,on the totem pole...my belief is the charge rushes to the end of the conductor..it takes roughly 2.5 milliseconds..the propagation time is treated as equivalent to charging time of a capacitor..
Another belief is when S2 closes and S1 opens,the charge on the conductor goes back to the negative terminal of the source.The magnitude of charge and discharge currents is decided by the conductor.
The whole idea is to make a single line power transmission using a totem pole source so that shock hazards are avoided since no ground connection is required,no expensive transmission grid engineering using towers and insulators and so on.
The loads to this line will be totally different design wise.
Having said all this,I want to use a goldleaf electrometer at the end of transmission line and see how it behaves when its antenna is brought near the end of the transmission line.

I think you may be a bit close to the Personal Theories restriction here, but for starters:

If you are treating your wire as a capacitor and charging it up to kV, 10's kV, 100's kV, ? with respect to earth, then you still have all the insulation and hazard issues.

You say you have no ground connection, but your battery will not charge the capacitor unless both the battery and other side of the capacitor are connected, by the earth. Even if you had a large sphere on the top of your totem pole, which was charged, that charge had to come from somewhere - the Earth - and will go back to Earth unless well insulated. When shared over the wire, the wire will have a potential difference with respect to the earth, so charge can flow from it to Earth and will similarly need insulation.

The power you can transmit depends on the potential difference and the rate of charge flow. If you have a large pd then you need insulation and all the usual infrastructure. If you have large rate of charge flow, then you have resistive losses and need thick cables.

How would you synchronise your switches? If the distances between source and loads were various, then the transmission times would be various. S2 switches could switch at different times, but S1 can't synchronise with all the S2s. So one wire for each load?

Would you deliver your very high voltage to end users? How would you bring it down to useful levels? Do you realize that using a large high voltage capacitor to charge many lower voltage capacitors entails an irreducible energy loss?

Welcome to PF.
You will find a few problems with your idea.
1. You do not have a capacitor you have a transmission line. What will happen when energy is reflected from the mismatch at the far end.
2. The switch will generate a step change in voltage. That will have high frequency harmonics and radiate EMI across the spectrum.
3. One side of the capacitor is ground. Where does the ground connect to the switch and battery system.

There is a SWER line = Single Wire Earth Return transmission line that works with single phase AC.
DC is used for underwater single wire power cable with seawater as the Earth return.

Well. If I take it right then you are actually flirting with the idea of 'wave conducting'. Not bad.
However, with this method your cable will work as an antenna => it'll lose energy through radiation. This can be prevented only by shielding your cable. And that's just another, more complicated cable...

I am not treating it as a capacitor but equating the propagation time as equivalent to it.
The load will be between the totem pole and the starting terminal of the long line (500 miles)
Since the load is in the parallel distributed way,may be some tens of miles, just a pair of S1 and S2 switches is sufficient.
Just imagine the whole configuration is in space.The charging and discharging currents should go back and forth through the loads.
If 500 miles propagation time is recreated as a single terminal module..the above action should take place.
Please treat charge like water with two switches and one end of the 500 mile long pipe connected to the totem pole.
