6. they drive air into a pipe on the top of a chamber

7. The pipe is fitted with a turbine which rotates as the air is forced past it.

8. As the waves leaves the chamber, air is sucked back down the pipe, keeping the turbine moving.

9. The turbine is connected to a shaft, which powers a generator to convert the energy into electricity.

10. Electricity is sent via pylons and cables to homes around the country.
