We make a big mistake powering the main coil on a single phase induction motor treating it as if it were the primary on a transformer due to the high resistance on that coil impeding current. How are we supposed to produce a magnetic field if we can't get much current to appear across all of that resistance/impedance/whatever?

Incidentally...

The starter coils are treated as if they were the secondary coils on a transformer. So, while we are powering up the main/primary coil, the secondary/starter coils are getting the "left-over" current from whatever magnetism managed to pass through the motor's armature.

This is so backwards.

When it comes to efficiency, Nikola Tesla was a stickler for efficiency!

The solution lies in applying line voltage to the starter coils. Since they are already shorted out to themselves, all we have to do is short them out to each other as well as retaining their self-shorted condition and electrically connect them to the main coil and short that coil out to itself as well. Then, we'll have ourselves a triple-shorted motor!...

1. The starter coils are self-shorted.
2. The motor coil is self-shorted.
3. Both sets of coils are shorted to each other.

This makes it possible to reduce the line voltage to rediculously low levels and, thus, save a tremendous amount of amp-hours on the battery.

But since we'll be passing a tremendous quantity of amperage through this tiny battery, it may be wise to replace it with a thin film, amorphous silica, solar panel.

It may also be advantageous to take advantage of one of Nikola Tesla's patents, entitled: "Adding A/C to D/C."

I don't think that was the plan. I think he was hiding his real motives for that patent as a block diagram for arranging two D/C voltage sources (represented by his two batteries in that patent; analogous to our two D/C voltage sources which we will be using to power our two sine wave generators), plus two loads, and a third voltage source described by Nikky's patent as an A/C source. But we'll be replacing that with our reactive circuit which will automatically qualify it as an oscillator.
