How would you represent the information from the following excerpt from the article about the girls who invented a generator that runs on urine?

Four teenage girls from Africa have figured out how to use urine as fuel for an electric generator. Fifteen-year-old Bello Eniola and 14-year-old Duro-Aina Adebola, Akindele Abiola, and Faleke Oluwatoyin created a generator that can produce six hours of electricity from one liter of urine and demonstrated their invention at Maker Faire Africa in Lagos, Nigeria. Here is how the machine works:

Urine is put into a cell, which extracts hydrogen.
The hydrogen goes into a water filter to be cleaned further. The purified hydrogen turns to gas, which is then pushed into the gas cylinder.
The gas cylinder pushes the hydrogen gas into a cylinder of liquid borax. The liquid borax removes the moisture from the hydrogen gas.
This purified hydrogen gas is then pushed into the generator to be used as fuel.
