Other than the main tracking feature of GPS, the system can also be used to detect and monitor in a range of additional and unique situations. The amount of snow on the ground can be measured from GPS signal noise, it can used to detect earthquakes, monitor volcanoes, and to analyse the atmosphere.
Jetopetra have developed a new fluidic propulsion system for aircraft that uses coander effect to pull air into a thruster using negative pressure, removing the need for propellers and reach speeds of Mach 0.8.
Researchers from the University of Washington and Stanford University demonstrated a new radio transmitter that uses almost no power to switch the flow of electrons heated by random thermal noise on or off to an antenna.
Physicists at École Polytechnique in Palaiseau have successfully used lasers to guide lightning over a Swiss mountain. The lasers create a pathway of low density, ionized air that the lightning can follow.
Tim Ferriss recently interviewed Stephen Wolfram on his podcast. I listened to the interview on the Christmas trip back to Ireland and found it fascinating. Stephen describes the work he and his company are doing in creating a new general model for Quantum Physics, which includes his new Ruliad computational space.
