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 role does government funding play in the development of the bio-ultra train?
