The Blanket Effect is intended for others to learn about weather modification and its related subjects in an easy to understand way. Started in 2005, this blog is a work in progress as the technology advances

Hard to 'See' Plasma

(Part 2 continues on our report of the history of barium related research in atmospheric chemistry, and concludes our first section of page 179 of the book, "The Century of Space Science", Published 2001 by J. A. M. Bleeker, Johannes Geiss, M. Huber. part 1)

Barium cloud experiments in the upper atmosphere

[Plasma] experiments are comparable to methods of observing the velocity of a homogeneous fluid.

A typical method involves spreading some coloured particles or metallic dust into the fluid. Normally, one uses only very small amounts in order not to disturb the behaviour of the fluid. (image right of equilibrium of sugar molecules, from

More than 90 percent of the cosmic objects are in a plasma state, but are also very dilute and therefore not visible except where concentrated in stars.

The cosmic plasma consists mainly of ionized hydrogen and helium molecules, which have an extremely small cross section for light-scattering and so, like the even smaller electrons, do not scatter enough light to make their presence visible.

Therefore, it would be interesting to inject into a cosmic plasma a suitable material that with has a cross section large enough for light-scattering to make the motion of cosmic plasma visible.

For a plasma with very high electrical conductivity, this is of particular interest, since every motion perpendicular to the magnetic field lines of force can be described as the motion of the magnetic lines force.
