Only Hope against dangerous solar storm like Carrington event is THIS cheap tech

Solar storms are not just a space weather phenomenon but also a cultural phenomenon as auroras. People travel to higher latitudes just to witness these light patterns in the night sky. However, this beautiful imagery has also played a role in people underestimating the truly horrifying effects of this 'missile' shot at Earth by our Sun. And to remember what it is capable of, one does not even need to travel much back in time. Just taking a look at the Carrington event in 1859 will showcase what an intense solar storm can do. Even in the low technological era of that time, a solar storm caused sparking and fires in multiple telegraph stations, halted the communication system and caused widespread power outages due to extensive damage to the power grid. And if a similar event were to happen to the Earth today surrounded by hi-tech infrastructure, the damage we will face would be unimaginable. So, is there any hope for us? Some believe that an inexpensive piece of technology could be our savior.

The solar storm experienced during the Carrington event was the most intense geomagnetic storm in recorded history. It is not easy to predict what the world might go through now if a similar storm were to strike the Earth. We rely on technology and communication systems more than ever and power grids essentially save lives if you consider that even the emergency systems like hospitals, are dependent on it. A solar storm like that would burn many satellites, destroy GPS, Internet and mobile networks, cause power failures and even start forest fires.

According to a Wired report, if just nine transformers suffered damage from a solar system, the US could face widespread power outages for months. And while this grim picture can be painted
