The Lightning-Scarred Planet Mars

The Lightning-Scarred Planet Mars David Talbott presents glimpses from the DVD, "The Lightning-Scarred Planet Mars" (Episode 2 in the series Symbols of an Alien Sky), now available from Mikamar Publishing http://www.mikamar.biz/ Since this video is part of a much larger presentation of evidence, and all of the evidence is interlinked, it is best to start at the beginning. For a playlist of selections from Episode One see:

Flux pinning

Flux pinning describes the interaction between a high temperature superconductor (HTSC) and a magnetic field. A member of Cornell's Space Systems Design Studio demonstrates the effect. Demonstration of magnetic flux pinning stiffness in 5DOF (one rotation DOF has negligible stiffness because the magnetic field is symmetric about the dipole axis) and then 6DOF for an asymmetric field. This principle could create non-contacting, switchable joints.
