Seven-year-old Edgar Vann is the lucky winner of an iPad for his idea, which was based on a solar powered system designed to save water by collecting rain water to use in place of mains water. Edgar included a diagram of how the system would work at his school, with the headteacher being able to operate a heating system for the collected water from their office.

Edgar said: “I enjoyed designing our energy saving school and I hope things like this will change the future.”

Solar power was a popular theme amongst the entries, with other designs including a solar powered fan control system and a solar powered, roof mounted weather station that controlled the school’s heating system.

Terry Sharp, BCIA President, said: “I was really impressed with the standard of entries, which have shown just how switched on many school children are about the environment. I would like to congratulate Edgar on his well deserved win and thank everybody who took part in the competition. The judging panel had a very tough job in deciding the winner and it was great to get an early glimpse at the future talent that could one day become key figures in our industry.”
