Researchers at Yale University are using a deep-earth tool called the Kawai multi-anvil press to create materials that can conduct electricity with zero resistance. They're focusing on sulfur trihydride, which acts as a superconductor at high temperatures but only under extreme pressure. The team hopes to find a way to make it stay superconductive after relieving the pressure.
Imagine being able to transmit electricity through wires without losing any energy. This would be a huge economic benefit and could revolutionize fields like medical imaging, quantum computing, and more.
Currently, almost half of the energy in transmission is lost as heat in copper wires. Scientists have been searching for materials that can act as superconductors at normal pressures and relatively high temperatures. One such material is sulfur trihydride (H3S), which has shown promise but only under extreme pressure - 150-200 gigapascals, equivalent to the pressure found halfway to Earth's core.
A team of researchers led by Lisa Pfefferle at Yale University is using a deep-earth tool called the Kawai multi-anvil press to create materials that can conduct electricity with zero resistance. They're focusing on H3S and have made significant breakthroughs, including developing a technique to synthesize it under much lower pressures and making it stable after relieving the pressure.
The team has already seen some encouraging results while working with other materials, such as turning platinum into a superconductor at extremely low temperatures. They're now working together with researchers from Yale's Earth & Planetary Sciences and Chemistry departments, as well as the U.S. Navy, to achieve their goal.
Why It Matters
This discovery could have a huge impact on India's energy needs and economy. If scientists can find a way to make materials superconduct at normal pressures, it would be equivalent to having thermonuclear fusion - a game-changer for the country's power generation and transmission systems.
