Mars or Earth the Devils are Electrified
Martian dust devils exhibit startling electrical
properties. Electric whirlwinds have also been identified on Earth.
As long ago as
March 2005, Electric Universe advocates wrote about the
surprising discovery of dust devils spinning across the
Martian deserts. The Spirit Rover returned several images of
large, glowing funnels raking across the flatlands, leaving
darkened trackways behind.
Since the
atmospheric density on Mars is so low (less that one percent
that of Earth), the question arose of how a strong “wind”
can carve the soil and leave multiple tracks that can be
seen from space? We might also ask how the global dust
storms are energized by such a rarified vapor of frigid
carbon dioxide gas?
The
conventional theory of dust devil formation on Earth
describes a vortex of warm air that begins as a horizontal
“rotator” near the ground. As the spinning air gains
momentum, it “stands up” vertically, forming a cylindrical
cloud of dust that twists its way over the surface,
gathering more debris as it goes. As it increases in
strength, it tightens its diameter like an ice skater
drawing in her arms. As it contracts, the dust storm spins
faster and faster.
However, on Mars
there is no vortex of spinning air to move into a vertical
orientation and form the dust devil. Yet, there are funnels
that climb thousands of meters into the sky on Mars and
engulf nearly a
whole hemisphere with their burden of sand and other
small particles during certain parts of the year. A better
explanation for dust devil formation on Earth as well as
Mars could very well be electricity.
Recent announcements
by atmospheric scientists have claimed that “saltation” is
generating the electric fields that they found years ago in
the dust devils of Arizona. “Saltation” means the
intermittent, leaping movement of particles of sand or
gravel, as from the force of wind or running water. In other
words, the sand particles are believed to be generating
electrical charges close to 10,000 volts per meter by
rubbing against each other.
In several
previous Picture of the Day articles, we have pointed out
that it is not necessary to postulate strictly mechanical
activity for the electric charges that have been found in
dust devils. To get the electric field, conventional
researchers believe, there has to be “charge separation”
that requires collisions of sand and soil particles. It is
those collisions, they say, that causes the larger particles
to become positively charged and the smaller ones to become
negatively charged. The wind then disperses them into
regions of sorted sizes, creating an electric field.
In the
Electric Universe theory, no collisions from bouncing
sand grains are necessary. Charge separation already exists
in the atmosphere. Without clouds like those on Earth to
send lightning down to ground level, the electric discharges
on Mars form giant whirlwinds that are part of an
interplanetary electrical circuit. It is that same circuit
that drives weather systems on Earth. If this is true, then
Martian “dust devils” and those on Earth are both
illustrations of how electricity behaves in the solar
system.
