Meet some of this year's BT Young Scientist hopefuls

A teenager’s brilliant idea could lift him to great heights in the BT Young Scientist and Technology Exhibition.

Michael Doyle, a second-year student at St Fintan’s High School in Sutton, Dublin, used mathematical formulae to describe a more efficient crane than those currently used.

“The advantage of the crane which I theorised can lift a bigger load and reduce the number of counterbalance weights that you need to maintain equilibrium,” explained Michael.
