For the first time in history, a satellite transmitted solar energy from space to Earth

QAZAQ GREEN. Scientists continue to search for clean and sustainable energy sources. One of the promising areas in this activity is the development of technologies that will make it possible to capture solar energy directly in space and then transmit it to Earth. Scientists from the California Institute of Technology (Caltech) have achieved some success in this, who managed to collect energy using an orbital satellite and transmit it to Earth, The Tech News Space reports.

We are talking about the Space Solar Power Demonstration (SSPD-1) mission, which is being implemented by a team of scientists from the Space Solar Power Project (SSPP) from Caltech in collaboration with Indie Semiconductor Inc., NASA’s Jet Propulsion Laboratory (JPL), Amazon Web Services and the startup GuRu Wireless, which is one of the divisions of Caltech. The joint activity led to the fact that scientists were able to collect some energy in Earth’s orbit and then transfer it to the surface of our planet, which can be considered a serious achievement. Detailed information about the work done was presented in article researchers, which was published in arXiv.

On Earth, people have learned to use sunlight to generate energy, but even the most advanced technologies have their drawbacks. For example, on a cloudy rainy day, the power of a solar panel can drop by 25%, and they cannot generate energy at night. At the same time, solar panels placed in orbit can continuously generate energy if they are oriented in such a way that they are always exposed to sunlight. What remains for scientists is to develop a reliable way to transfer energy from orbit to Earth, where it could be used to power businesses, homes and more.
