Kardashev scale
See Kardashev scale
Someone reads too much SF. I even write the stuff and I've read it for 50 years. However while it might work as a plot device in a story, my money is on a natural explanation.
Motive: Why is someone going to build a massive generator and power a sail? Crazy Eddie is fictional.
Means: There is no evidence that such so called "Advanced" civilisations exist or that the Kardashev scale is any more than EE "Doc" Smith style "Skylark" extrapolation.
