<h2>NASA’s Solar Shield to mitigate damage to power grid from severe solar storms</h2>The solar storms that cause the stunning aurora borealis and aurora
australis (or northern and southern polar lights) also have the
potential to knock out telecommunications equipment and navigational
systems and cause blackouts of electrical grids. With the frequency of
the sun’s flares following an 11-year cycle of solar activity and the
next solar maximum expected around 2013, scientists are bracing for an
overdue, once-in-100 year event that could cause widespread power
blackouts and cripple electricity grids around the world. It sounds like
an insurmountable problem but a new NASA project called “Solar Shield”
is working to develop a forecasting system that can mitigate the impacts
of such events and keep the electrons flowing.<br><br>Artigo completo em:<br><a href="http://www.gizmag.com/nasa-solar-shield/16744/">http://www.gizmag.com/nasa-solar-shield/16744/</a><br clear="all"><br>73!<br><br>-- <br>
