Sentient satellites can solve global warming for 1 billion years: Elon Musk

Billionaire Elon Musk proposed a system of sentient satellites launched into Earth-Sun Lagrange points by mass drivers on the Moon to tackle global warming for about 1 billion years. He said switching to sustainable energy alone would not prevent extreme extinction events. "Space satellites...and massive geo-engineering will be needed or it'll be game over," he added.
