    The term “Moonshot Thinking” has become popular in the last few years and represents pursuing objectives that appear undoable, but it could redefine humanity if implemented. It should tackle enormous societal challenges ...
  • Small scale simulation of lightning using vertical wires deployed by drones: on the land and sea peak current asymetry 

    Montañá Puig, Juan; Fontanes Molina, Pol; Arcanjo, Marcelo; Urbani, Michele; Williams, Earle Rolfe; Romero Durán, David; Horta Bernús, Ricard; López Trujillo, Jesús Alberto; Van der Velde, Oscar Arnoud; Pineda Rüegg, Nicolau (2022)
    Conference report
