Here are some extracts from the article. Complete the sentences by filling in the spaces.

Now I know that trying to ________ the future is hard, but I reckon that an electric ________, powered by a fuel cell running on ________, could be a goer! If you remember ________ to your chemistry classes at school, ________ is H2O. In other words, a molecule of water is ________ up of two atoms of hydrogen, and one atom of ________. If you use energy, and pass electricity through water, you can ________ water into hydrogen and oxygen. And you ________ run this reaction backwards, and ________ hydrogen and oxygen to give you water and energy. (In ________, the word, "hydrogen", means "maker of water" in ________ original Greek language.)

A fuel cell is ________ similar to a battery. Both a fuel ________ and a battery turn a ________ reaction into electrical energy. But a ________ is sealed, and when the "goodness" in the chemicals is used up, the battery is flat. A ________ cell is like a battery, but with one ________ different difference - you can pump in the chemicals indefinitely. Fuel cells ________ in hydrogen and oxygen, and give ________ pure drinking water, and electricity. You ________ the electricity to run electric motors.
