Hydrogen As A Fuel
Hydrogen powered cars, etc. are already working at Birmingham and other universities. Pupils make hydrogen and oxygen and test them. They are then asked to work out the best place to make hydrogen using sunlight. They should work out the costs of transporting from source to point of use - including compressing/liquefying the gas. Internet research, graphs, spread-sheets, etc. can be used and make this relevant to the challenge subject. Suitable for pupils aged 12-16. (In-school experiment, 30 mins, Homework 4+ hours)
