Human sewage, rotting food to power new trains

The video discusses the introduction of a bio-ultra train in Britain, which will be powered by biomethane, a renewable gas derived from organic waste. The train aims to replace diesel engines, offering a cleaner alternative. Biomethane is produced in sewage plants using fermentation tanks filled with organic waste. The methane gas generated is then converted into electrical power to drive the train's motors, allowing it to reach speeds of up to 80 km/h.

What is the primary goal of introducing the bio-ultra train in Britain?

• To expand railway networks

• To reduce the use of diesel engines

• To decrease train ticket prices

• To increase train speeds

What is biomethane primarily made from?

• Fossil fuels

• Organic waste

• Solar energy

• Wind power

Which of the following is NOT used in the fermentation tanks to produce biomethane?

• Plastic waste

• Rotting food waste

• Other organic waste

• Human sewage sludge

How is the methane gas separated from other gases in the production process?

• By filtering through sand

• By siphoning it off

• By using a chemical reaction

• By cooling the mixture

What is the maximum speed expected for the bio-ultra train?

• 100 kilometers per hour

• 120 kilometers per hour

• 80 kilometers per hour

• 60 kilometers per hour
