The shortlist for this year’s James Dyson Award has been announced, with 20 students from around the world nominated for their engineering inventions.

Several of this year’s cohort have come up with concepts designed to improve urban living, including plastic cutlery made from potato waste, a robot to combat water pollution and prefabricated ants nests for the cultivation of the insects as a food source.
“The breadth and ambition of the entries we have seen this year is outstanding,” said Peter Gammock, VP of Design and New Technology at Dyson. “Young engineers are restless in the face of global issues, and they see technology as a catalyst for creating a better future. They demonstrate clearly how simple ingenious concepts have the power to revolutionise the way people live.”
One entry that has grabbed the judges’ attention is Lighthouse, a soft robot that can detect leaks inside water pipes. As the robot passively flows through a pipe and navigates around pipe elbows, a sensor is tugged by the suction force of a water leak. When a leak is detected, Lighthouse measures the strength of the tug and records the location. Inventor You Wu said the inspiration for the robot came from his childhood in China, where water shortages were a regular occurrence.
“My interest in environmental sustainability started in childhood with a conflict between resource scarcity and population growth,” said Dr Wu, a recent doctoral graduate of MIT.
“When I grew up in China, my community had one day without power and another day without water every single week. The city regulated the supply to all communities to lower the burden on the power grid and water system. I grew up thinking we were good citizens conserving energy and water for the greater good. However, when I learned that every day 20 per cent of clean water in the world is lost due to leaks while we were making a sacrifice to conserve water, I thought this was wrong and I needed to change it.”

Other than for cooking and drinking, surely ‘most’ water consumption does NOT need to be of ‘human’ quality: so why do we not offer two standards? I believe our Victorian ancestors seriously considered such, but were worried that they would be mixed up? They surely did this at a time when infectious diseases were rife, food standards were negligible, and difficult to treat for medicine was not well advanced. They were frightened of plagues and consequent mass hysteria. We do not now live in such a scenario: yet that thinking still pervades ‘public health’.
Perhaps value engineering and operations research have a much greater role to play in defining the complete scenario of sensible Health & Safety. Surely, just as we cannot totally eradicate traffic accidents, and simply try to limit their effects on the human body (belts, crash panels. airbags exposed to such) is there a place for similar thinking on water supply, cleanliness of air etc. Are we jointly and severally simply finding or developing cleverer and cleverer ways of doing ‘stuff’ which is actually less and less necessary.
It is possible for every household to have their own dual quality water supply by installing a grey water recycling system. The system collects and recycles water from hand basins, baths, showers, washing machines and dishwashers for use in toilet flushing and in the garden reducing water consumption by upto 50%.
Was unaware of this: Thank you!
Though I am reminded of the comment of one of the Quality Management gurus (I believe it was Demming) who when he had told a client to reduce waste by doing by XYZ, and been told “we know all that..” said… “Then why aren’t you doing it!”
