Marcos Rubinstein (HES-SO), Farhad Rachidi (EPFL), and PhD students Amirhossein Mostajabi (EPFL) and Mohammad Azadifar (EPFL) presented their work on simultaneous records of lightning current at 380 km distance associated with a bipolar flash initiated from the Säntis station during the International Symposium on Lightning Protection (XIV SIPDA) in Natale, Brazil.
Pr J-P Wolf (UNIGE) talks about the laser lightning rod on German TV.
During their 2nd meeting in Santis, Switzerland, the LLR team visited the Santis tower, where the lightning campaign will be performed. Transportation, installation and weather conditions were the main topics addressed.
Prof. Jean-Pierre Wolf from the UNIGE team gave an interview on the German National Radio about laser rods. “These laser pulses are so intense that they change the characteristics of the air, they ionize the air and create an electrically charged channel, which has a diameter of only one tenth of a millimeter, but can be very long, up to 100 meters. A kind of ultra-intense Spaghetti.” Read the full interview
The European Commission gave its approval to the laser lightning rod project, funded under the Horizon2020 programme. The LLR project aims to investigate and develop a new type of lightning protection based on the use of upward lightning discharges initiated through a high-repetition rate multi-terawatt laser.
