Geothermal energy company Fervo Energy have discovered a way to utilise a geothermal well as a battery. By drilling cracks into geothermal hard rock, pumping lots of water in and sealing the well, the water can later be released at high pressure, allowing energy to be delivered at high output at times when renewables are generating low output.
Researchers led by Lining Yao at Carnegie Mellon University developed a biodegradable wooden self drilling seed carrier which can be deployed from the air.
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.
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.
Researchers at Carnegie Mellon University have developed a WiFi based human pose sensing system that can identify multiple people and their positions in a room using the phase and amplitude of the WiFi signal, filtered using machine learning models. The system can map the UV coordinates of body regions and is comparable to image based recognition systems.
Researchers at University of California developed a new technique to break down 95% of PFAS "forever chemicals" in water using UV light and hydrogen gas.
Researchers at the University of Sydney have developed a sodium sulphur based battery that demonstrates four times the energy storage capacity compared to lithium based batteries.
