The UK-based Space Solar is presenting a breakthrough in wireless power transmission technology, bringing the age of space-based solar power by delivering gigawatts of clean energy to Earth using massive solar arrays placed in orbit.

Sunlight in space is virtually uninterrupted and is not limited by weather conditions or the time of day, which means the idea of harnessing it has immense potential for addressing global energy needs. While this concept has been around for some time, only the recent developments of reusable rockets and declining launch costs renewed the interest in this potential game-changer.

According to Techxplore, Space Solar’s innovation involves a unique 360-degree wireless power transmission system, marking a technological leap and addressing a major challenge in space-based solar implementation. While traditional systems require large rotating joints to continuously align their solar panels with both the sun and the Earth-based receiver, Space Solar’s HARRIER allows for energy transmission in all directions without the need for moving parts, improving both performance and reliability.

Space Solar’s vision reportedly consists of a kilometer-wide satellite with solar panels and a system of mirrors to concentrate the sunlight. The electricity generated will be converted into high-frequency radio waves and beamed down to a fixed ground-based receiver, providing uninterrupted, gigawatt-scale clean power.

However, the concept of space-based solar power has its challenges, including the need for significant technological innovation to deal with the sheer scale (both in terms of construction and energy transmission), and the need to address concerns regarding the safety of high-power wireless transmission and potential impacts on space debris.

The company is receiving support from the UK government and the European Space Agency, working together towards making space-based solar a reality. This innovation could significantly transform the global energy landscape, bringing a future in which clean, dependable energy is beamed down directly from space, making this science-fiction-like dream a reality.
