One fuel cell for 100 years.

Thorium fuel cars are a concept involving the use of thorium, a radioactive metal, as a source of energy to power vehicles. Here’s an overview:

1. **Thorium as a Fuel**: Thorium is abundant and has potential as a nuclear fuel. It can be used in a process called nuclear fission, where thorium atoms are bombarded with neutrons to release energy.

How a disc brake system works in a car:

1. **Brake Pedal Pressed**: When you press the brake pedal in your car, it activates the hydraulic system.

2. **Hydraulic Pressure**: The brake pedal press increases the pressure in the brake fluid within the brake lines.

3. **Caliper Activation**: The increased pressure forces the brake fluid into the brake calipers located near each wheel.

4. **Brake Caliper**: Each caliper houses one or more pistons. When the brake fluid enters the caliper, it pushes the pistons outward.

5. **Brake Pads Squeeze**: As the pistons extend, they push against the brake pads, which are held in place within the caliper.

6. **Friction with Rotor**: The brake pads, typically made of a high-friction material, press against both sides of the rotor, creating friction.

7. **Heat Generation**: The friction between the brake pads and the rotor generates heat.

8. **Kinetic Energy Conversion**: The kinetic energy of the rotating wheel and the vehicle is converted into thermal energy (heat) due to the friction.

9. **Deceleration**: The friction between the brake pads and the rotor slows down the rotation of the wheel, thus decelerating the vehicle.

10. **Heat Dissipation**: The heat generated during braking is dissipated into the surrounding air and through the rotor itself, preventing overheating.

11. **Braking Effect**: The combination of friction and pressure applied to the rotor slows down or stops the vehicle, depending on the force applied to the brake pedal.

12. **Release**: When you release the brake pedal, the hydraulic pressure decreases, allowing the brake pads to retract slightly from the rotor, reducing friction and allowing the wheel to rotate freely again.

This process repeats every time you press the brake pedal, providing controlled and effective braking performance.
