Last year marked the 270th anniversary of Benjamin Franklin’s lightning rod — but it’s more than a relic of history. The Franklin rod remains in use today because the simple design exploits ...
Lightning rods that use laser beams can efficiently (and safely) guide bolts of lightning, preventing random strikes, scientists explain. Here’s how they work.
Benjamin Franklin invented lightning rods in the 18th century, and the devices have been protecting buildings and people from the destructive forces of lightning ever since.
This 3-D reconstruction models a lightning strike captured by high-speed cameras in July 2021. It shows the moment that the lightning bolt hit a metal rod atop a tower, its path guided through the ...
Lightning rods, dating back to Franklin's time, are metal rods atop buildings, connected to the ground with a wire, that conduct electric charges lightning strikes harmlessly into the ground.
A high-speed photo of lightning rods at work during an electrical storm in São José dos Campos, Brazil, is helping scientists understand how the devices compete to attract strikes and keep ...
“We found, from the first laser lightning event, that the discharge could follow the beam for almost 60 m (197 ft) before reaching the tower, thus increasing the radius of the protection surface ...
