Re: Sorry to pour cold water on a plasma jet
Well, his statement "...because you are tens times closer to the earth compared to geostationary satellites in low Earth orbit." is, to quote Wolfgang Pauli, "This isn't right. This isn't even wrong." So it makes one wonder what else is ill-conceived.
My reaction exactly. I stopped reading at that point.
And kudos for the Pauli quote.
I'm not too keen on referring to air as "fuel" in this context either. To me, that implies air is the source of the energy used to produce thrust. It isn't, it's just reaction mass (or working mass).
