To protect buildings and the people living in them from the effect of lightning falling from the sky, rods are placed on the roofs. These rods absorb electricity and send it to the ground. Now Brazilian scientists have invented a technique to send lightning underground before it strikes. These rods throw lightning discharges into the sky before lightning strikes. This discharge attracts lightning towards itself. Lightning collides with these rods and goes to the ground.
Scientists set up slow motion cameras for testing
Let us tell you that Brazilian scientists put rods on the buildings located in the north-east of Sao Paulo city. This type of event happens in less than a millisecond. It is very difficult to make pictures or videos of this event. In such a situation, scientists installed a high-speed video camera 450 feet away so that pictures of the entire incident, including lightning in the sky, could be taken on the side of the road. This camera has captured 40 thousand pictures every second.
These sticks will be helpful in saving lives
A senior researcher at the National Institute for Space Research said, “We recorded 31 electrical discharges, which appeared to attract electricity from the sky. These rods are activated when the weather changes in the sky. Makes it positive. In such a situation, it is a good way to save people.
Effect of sky is being reduced with the help of laser in Greece
A few months ago, Greek scientists changed the direction of lightning by rapidly firing lasers in the sky. This experiment established that laser beams could be used instead of lightning rods on buildings. Due to which there will be no loss of life and property due to lightning. However, it will take time to fully develop this experiment.
