Lecture Notes: Elon Musk's Water Engine

Introduction

• Humans are 70% water, 30% land.
• Freshwater availability tied to energy and transport.
• Elon Musk announced a Tesla shift from battery-powered to hydrogen fuel cells.
• Unveiling a water engine that could revolutionize transport.

Background on Elon Musk's Vision

• Focus on green energy and transportation.
• Tesla's mission to challenge traditional cars with electric vehicles.
• SpaceX goals: affordable space travel, colonization of Mars.

Tesla's Journey

• Founded in 2003 amid skepticism about electric cars.
• Successes: Roadster, Model S, Model X, Model 3, Model Y.
• Innovations: Better batteries, longer ranges, partial self-driving.
