Solar Mirrors In Space Could Bring Light to the Night
come a long way: to advance significantly compared to how something or someone was before
Solar energy is clean and cheap, but it only works when the sun is shining. A new plan could change that by using space mirrors to send sunlight to Earth after dark.
A company called Reflect Orbital has raised 8.7 million dollars for the project. They are planning to launch satellites with mirrors that will reflect sunlight to solar farms after dark.
If successful, they could provide an extra 30 minutes of sunlight to power plants every day. Ben Nowack, the company’s founder, said this is not a new idea. “Russians launched a reflector satellite in the 1990s, and it worked, but we’ve come a long way since then.” Modern advancements allow for lighter satellites. The company is testing its first satellite in 2025 to see if the technology works as planned.
