Ref: http://www.physicsweb.org/article/news/7/11/16
The inverse Doppler effect has been observed in an experiment for the first time. Nigel Seddon and Trevor Bearpark at BAE Systems in Bristol in the UK saw the effect in an electrical transmission line. The researchers admit that the results are counterintuitive but say the work could have applications as a radiation source in medicine and communications (N Seddon and T Bearpark 2003 Science 302 1537).

See: http://www.physicsweb.org/article/news/7/11/16 You missed the best part: "Seddon and Bearpark made a transmission line that contained magnetic induction coils and capacitors. The group and phase velocities of waves in the line pointed in opposite directions, a phenomenon known as "anomalous dispersion". In most materials the two velocities are parallel to each other." That is the claimed fabrication, inductors and capacitors, for moron Orman's faster-than-light transmission line. We thus view the utterly delightful circumstance of Orman not only being a raving idiot, but being an incompetent raving idiot for missing some beautiful publishable physics. Orman was too stooopid to realize the anomaly, and that if the anomaly propagated at the measured 1/10 lightspeed... then by merely inverting the phenomena he gets 10X lightspeed.
