Read the following excerpt. Explain how you could represent this information using a text feature. 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.
