From the personal writings of Nikola Tesla, as well as from your lectures I understand that dialectrica used in a spark gap is very important.
Above you discussed the first step of radiant energy conversion, please allow me to scrutinize and analyze the second step.
In one of your lectures you said that the spike must be created in a way in the spark gap, that it will crack only once.
Tesla in in his personal notes says the same - the electric ark must be avoided. He describes that this electric ark is created in conductive gases, such as air, on the molecular level and the molecules are charged and discharged that quickly that thereby light is created. In this way light currents are caused and the energy is lost, therefore he made a magnetic spark gap to interrupt the electric ark. The best would be a dialectrica, such as vacuum, or something similar, that would lock up the spike, thus isolating it, while it 'bolts' through the spark gap.
The external appearance would be that 'is cracks only once', since no electric ark is created.
Could you give some suggestion on what dialectrica would be suitable for this kind of spark gap?
My greatest sympathies go towards vacuum tubes, but since they are very difficult to be manufactured, I would do a compromise and try liquid dialectrica, such as compressing transformer-oil, liquid hexane, or other liquid dialectrica in a spark gap.
What do you think about this? What kind of spark gaps did Dollard use?
Thank you very much and best of greetings,

Shad,
Dollard used large vacuum triodes for his Magnifying Transmitter, and glass enclosed hydrogen spark arresters for the other BSRF demonstrations.
But let's start at the beginning. What was Tesla trying to do? He was trying to produce a simple DC square-wave pulse train. But he didn't have ANY electronic control devices. No 555 timer chips. No transistors. No vacuum tubes. He only had coils, capacitors, mechanical contacters, and spark gaps.
So, what does Tesla's longitudinal electrostatic wave-front look like? It looks like a DC square-wave pulse train where the pulse repetition rate is one million impulses per second, the duty-cycle is 10% On and 90% OFF, and the voltage in each impulse is 50,000 volts DC or more. This is what Tesla wants the circuit to do. This is what he wants to create by the discharge of his capacitor stage in the circuit.
So, if the spark gap is his "circuit controller" then he only wants a "single crack" each time the capacitor discharges. Just a single, unidirectional impulse of electrostatic charge to proceed forward before the circuit shuts off again. Then, the capacitor can charge up again for the 900 nanoseconds the spark gap is quiet and then discharge all of the stored energy again in 100 nanoseconds. Then repeat indefinitely.
It creates a "staccato of electrostatic bursts." Don't make this mysterious, because it is not. It is no more difficult to understand than the output of a 555 timer chip. Its just that we are talking about very high voltage DC, and very high pulse repetition rates. What is difficult is finding the circuit components that allow you to create these conditions without self-destructing!
In my
Tesla's Radiant Energy DVD I go through all of Tesla's patents and discuss the various methods he used. They included spark gaps quenched by magnets, spark gaps quenched by blasts of hot air, spark gaps in insulating oil, spark gaps across rotating contacters. All of these methods work to one degree or another.
In the 1920's, as vacuum tubes started becoming available, John Bedini and I are convinced that Tesla went to Lee DeForest and had him build the first experimental Thyratrons. This is a family of circuit controlling devices specifically designed to conduct a unidirectional impulse, only when triggered, and then automatically shut off when the voltage drops to ZERO. This is most easily seen today in the function of the Thyrister, the simplest of which is the SCR. The problem with SCRs today is that they are not designed to shut OFF fast enough for the purposes of these circuits.
I hope this helps.
