Smart switch could save lives on farms
The scientific smarts of a young Southlander could save lives on farms.
James Hargest College pupil Maria Burnett took home the premier technology award from the NZAS Science and Technology Fair for her project, Smart Switch.
For the project, the 16-year-old invented a shield to cover the power take-off (PTO) shaft on tractors.
The PTO shaft carried electricity from the tractor to the implement attached to it and spun 16.6 times a second, so was very dangerous, Maria said.
The smart switch not only shielded farmers from the shaft if they fell on it, but would also cut its power, through two switches.
She decided to design a protective shield after her father, a dairy farmer at Dacre, told her how dangerous PTO shafts were, she said.
The teenager worked on the project for about four months, putting in some long hours around school and sporting commitments.
With a little inspiration and guidance from teachers, the project also opened her to a whole new world of learning, she said.
"I'm not really a workshop girl, but I've learned a lot.
"Before this I never had an interest in technology. Now I'm really interested in it."
Maria hopes the smart switch will eventually be available on the market, using industrial plastic instead of sheet steel.
The NZAS Science and Technology Fair finished up with a prizegiving last night at the Ascot Park Hotel.
Year 5 to 13 pupils from about 20 schools throughout Southland entered the annual event.
Topics investigated included if egg size affected the taste of cakes, which design of smoke alarm was most effective and how leg length impacted a rower's ability.
