Introducing the non-radiating antenna

Physics World

An international team of physicists has created what might seem like a contradiction in terms: a non-radiating source of electromagnetism. Maxwell’s equations tell us that accelerating charges radiate energy in the form of electromagnetic waves. Electric moments without any poles.

Bolivia has high solar power potential but faces challenges scaling up

A Greener Life

The Altiplano plateau in western Bolivia has some of the world’s highest and most consistent levels of solar radiation, creating a high potential for solar photovoltaic power in the region, but structural challenges may prevent scaling.

Solar cell keeps going after sunset

Physics World

A new type of photovoltaic cell continues working after sunset thanks to an additional generator that harvests electricity from the temperature difference between the cell and its surroundings. Fan and colleagues tested their device on a rooftop at Stanford, taking measurements on 10–13 October 2021. Thermoelectric effect.

Artificial intelligence can spot holes in the Sun’s corona

Physics World

These funnels are rooted deeper in the Sun, in the star’s light-radiating photosphere, and they extend far into interplanetary space. Through future improvements, Jarolim’s team hope that their model could soon provide organizations that manage electrical and telecoms infrastructure with better warnings of damaging geomagnetic storms.
