You can just use this if you want a "circuit in space".
I've never inferred that in any of his work. He talks about an electric current that terminates in space so as not to need a circuit.
Electricity in the imaginary space I guess is referring to what people like Enst Alexanderson did after him where the time of propagation can equal to 0 in-between whatever points in the universe. I guess that's how civilizations between galaxies communicate?
With those sorts of colours in an RGB 8-bit format? I doubt that.
