Why Private Billions are Flowing into Fusion

What is the main challenge with achieving nuclear fusion?

• Creating a small sun on Earth

• Building a reactor large enough to contain the plasma

• Heating a material to 10 times the temperature of the sun

• Finding enough hydrogen to fuel the reaction

What is plasma?

• A chemical reaction

• A form of energy

• A type of liquid metal

• A state of matter beyond gas

What is the goal of fusion power?

• To replace fossil fuels with a clean, unlimited energy source

• To explore outer space

• To create a new form of weapon
