## Nuclear Fusion | The Power of the Stars
- Introductory slide explaining that fusion is the process that powers stars.

## How Fusion Works
- Heat and pressure smash hydrogen atoms together to form helium, releasing immense energy.

## Fusion vs. Fission
- **Fission (Splitting):** Used today, splits atoms, creates radioactive waste, risk of meltdown.
- **Fusion (Joining):** Joins light atoms, no long-term waste, zero meltdown risk.

## Why Fusion?
- **Abundant Fuel:** Isotopes from seawater.
- **Carbon Free:** No greenhouse gas emissions.
- **Inherently Safe:** Reaction stops instantly if interrupted.

## The Tokamak Approach
- Uses powerful magnets in a donut-shaped chamber to contain super-hot plasma.

## What Can Fusion Do?
- Unlimited energy for cities and potential for faster space travel to Mars.

## Timeline to Power
- **1950s:** First Tokamaks invented.
- **2020s:** ITER Assembly.
- **2030s:** First Net Energy Demonstration.
- **2050s:** Commercial Fusion Power Plants.

## Fuel from Water
- Uses Deuterium (seawater) and Tritium (Lithium). One glass of seawater contains the energy equivalent of a barrel of oil.
