I think someone has placed a huge mirror in top of the mountain 🏔️ to reflect the sun rays towards their city. Because that mountain might be blocking the sunrays 🌄.
And I assume the oval shape object might be the vehicle 🚜 for cleaning and maintening the mirror .
Who knows in the near future we may get such technology 👨💻.
Nice imagination of the future. 👍
