Hi everyone,

Just wanted to share this information along. I think it is interesting that Nasa is more concerned about the Electrical Grid then our health and well being. How safe really is this solar shield and what are they shielding us from? Higher conscienceness, free energy perhaps? Our money goes to Nasa to keep us in the dark, I believe Nasa has harmed our spiritual growth as a nation. For the last hundred years our electrical grid has enslaved humanity to a great degree. It is devoid of the photon, positron particles. And I am not an electrician but I am aware of what happened to Tesla. All his work was taken and used for selfish reasons and destructive purposes. I believe that Nasa is still part of the old ancient regime of control and doesn't want us to leave the Control Grid because this is where they make Money.

Please contact them if you agree I want to get out of the grid and the harmful EMF frquencies that has proven to be detrimental to our cardiovascular system. I am just now learning about Tesla's work and the Resonance energy that provides light and warmth and sustainable living from the Universe and not from just our Planet. I believe that our Earth needs to balance itself with the electron and positron energy fields more then ever now. Free energy sustainable living, clean water, homes this is our future and Tesla's work will provide more energy so we can do our work because of unconditional love and not fear.


Thank you for reading, Katherine

Solar Shield--Protecting the North American Power Grid


Along so potent it fills the skies of Earth with blood-red auroras, makes compass needles point in the wrong direction, and sends electric
currents coursing through the planet's topsoil. The most famous such storm, the
Carrington Event of 1859, actually shocked telegraph operators and set some of
their offices on fire. A 2008 report by the National Academy of Sciences warns
that if such a storm occurred today, we could experience widespread power
blackouts with permanent damage to many key transformers.


What's a utility operator to do?

>A new NASA project called "Solar Shield" could help keep the lights on.


"Solar Shield is a new and experimental forecasting system for the North American power grid," explains project leader Antti Pulkkinen, a Catholic University of America research associate working at NASA's Goddard Space Flight Center. "We believe we can zero in on specific
transformers and predict which of them are going to be hit hardest by a space
weather event."


The troublemaker for power grids is the "GIC" – short for geomagnetically induced current. When a coronal mass ejection (abillion-ton solar storm cloud) hits Earth's magnetic field, the impact causes
the field to shake and quiver. These magnetic vibrations induce currents almost
everywhere, from Earth's upper atmosphere to the ground beneath our feet.
Powerful GICs can overload circuits, trip breakers, and in extreme cases melt
the windings of heavy-duty transformers.


This actually happened in Quebec on March 13, 1989, when a geomagnetic storm much less severe than the Carrington Event knocked out
power across the entire province for more than nine hours. The storm damaged
transformers in Quebec, New Jersey, and Great Britain, and caused more than 200
power anomalies across the USA from the eastern seaboard to the Pacific
Northwest. A similar series of "Halloween storms" in October 2003
triggered a regional blackout in southern Sweden and may have damaged
transformers in South Africa.


While many utilities have taken steps to fortify their grids, the overall situation has only gotten worse. A 2009 report by the North American Electric Reliability Corporation (NERC) and the US Department of Energy concluded that modern power systems have a "significantly
enhance[d] vulnerability and exposure to effects of a severe geomagnetic
storm." The underlying reason may be seen at a glance in this plot:

Since the beginning of the Space Age the total length of high-voltage power lines crisscrossing North America has increased nearly 10 fold. This has turned power grids into giant antennas for geomagnetically induced currents. With demand for power growing even faster than the grids
themselves, modern networks are sprawling, interconnected, and stressed to the
limit—a recipe for trouble, according to the National Academy of Sciences:
"The scale and speed of problems that could occur on [these modern grids]
have the potential to impact the power system in ways not previously
experienced."


A large-scale blackout could last a long time, mainly due to transformer damage. As the National Academy report notes, "these
multi-ton apparatus cannot be repaired in the field, and if damaged in this
manner they need to be replaced with new units which have lead times of 12
months or more."


Permanent damage to the Salem New Jersey Nuclear Plant GSU Transformer caused by the March 13, 1989 geomagnetic storm.


That is why a node-by-node forecast of geomagnetic currents is potentially so valuable. During extreme storms, engineers could
safeguard the most endangered transformers by disconnecting them from the grid.
That itself could cause a blackout, but only temporarily. Transformers
protected in this way would be available again for normal operations when the
storm is over.


The innovation of Solar Shield is its ability to deliver transformer-level predictions. Pulkkinen explains how it works:


"Solar Shield springs into action when we see a coronal mass ejection (CME) billowing away from the sun. Images from SOHO and
NASA's twin STEREO spacecraft show us the cloud from as many as three points of
view, allowing us to make a 3D model of the CME, and predict when it will
arrive."


While the CME is crossing the sun-Earth divide, a trip that typically takes 24 to 48 hours, the Solar Shield team prepares to
calculate ground currents. "We work at Goddard's Community Coordinated
Modeling Center (CCMC)," says Pulkkinen. The CCMC is a place where leading
researchers from around the world have gathered their best physics-based
computer programs for modeling space weather events. The crucial moment comes
about 30 minutes before impact when the cloud sweeps past ACE, a spacecraft
stationed 1.5 million km upstream from Earth. Sensors onboard ACE make
in situ measurements
of the CME's speed, density, and magnetic field. These data are transmitted to
Earth and the waiting Solar Shield team.


"We quickly feed the data into CCMC computers," says Pulkkinen. "Our models predict fields and currents
in Earth's upper atmosphere and propagate these currents down to the
ground." With less than 30 minutes to go, Solar Shield can issue an alert
to utilities with detailed information about GICs.


Pulkkinen stresses that Solar Shield is experimental and has never been field-tested during a severe geomagnetic storm. A small number
of utility companies have installed current monitors at key locations in the
power grid to help the team check their predictions. So far, though, the sun
has been mostly quiet with only a few relatively mild storms during the past
year. The team needs more data.


"We'd like more power companies to join our research effort," he adds. "The more data we can collect from thefield, the faster we can test and improve Solar Shield." Power companies
work with the team through EPRI, the Electric Power Research Institute. Of
course a few good storms would help test the system, too. They're coming. The
next solar maximum is expected around 2013, so it's only a matter of time.
