A new way to Store Thermal Energy

“What we are doing technically,” Han explains, “is installing a new energy barrier, so the stored heat cannot be released immediately.” In its chemically stored form, the energy can remain for long periods until the optical trigger is activated

A new phase-change material stores heat in a stable chemical form, then releases it later on demand using light as a trigger. In large parts of the developing world, people have abundant heat from the sun during the day, but most cooking takes place later in the evening when the sun is down, using fuel – such as wood, brush or dung – that is collected with significant time and effort.

IBM has announced a milestone in its race against Google and other big tech firms to build a powerful quantum computer. Dario Gil, who leads IBM’s quantum computing and artificial intelligence research division, said it’s scientists have successfully built and measured a processor prototype with 50 qubits. Gil says it’s the first time any company has built a quantum computer at this scale.
