A father-of-three may be set to help other despairing parents to achieve cheap energy bills thanks to his latest invention.
Brian O'Reilly created the Energy Egg after becoming sick of finding his children had left TVs and computers turned on when they were not being watched or used.
The 37-year-old came up with the concept of a device that can sense when a room is empty and automatically turn off unused electrical items.
"It was always down to me to do the trawl at the end of the night. I thought, it doesn't have to be like this – we've got the technologies to do this automatically," Mr O'Reilly explained.
Using motion sensors similar to those in household alarm systems, the Energy Egg detects when there is no one in a room and kills the power to a wirelessly controlled adaptor.
According to the World Wide Fund, if all consumers in industrialised countries unplugged chargers and switched off domestic appliances instead of using standby, 24 coal-fired power stations could be closed.
