Kinetic Energy Recovery System (KERS) In Alpine Skis

Alpine ski manufacturer Head has implemented a Kinetic Energy Recovery System (KERS) in their skis!

For those who follow Formula One you will be familiar with the term KERS; the Kinetic Energy Recovery System that stores the kinetic energy whilst the vehicle is braking to use later when the vehicle is accelerating. And you may have read that the Royal Navy want to use KERS to power laser guns on its warships.

KERS In Skis

So why would you want to have KERS in your skis? To go faster like an F1 car, or blast fellow skiers off the piste with a James Bond-like laser in your ski; I think not! It’s all to do with turning.

The skis have piezoelectric fibres which transform kinetic energy whilst skiing into electrical energy. This electrical energy is stored for when the skier is at the end of their turn, when the ski is at maximum flex, and released to stiffen the tail of the ski. This gives the skier extra ‘pop’ into their next carving turn.

The Head Supershape iTitan skis have KERS, so get motoring!

As with comedy; it all about ….. timing. So the boffins at Head skis programme the sensors to release at the appropriate point of the out-turn and depending upon the ski type how stiff to make the tail of the ski. The Head iSupershape iTitan skis have KERS technology.

Clever stuff, but I still like the idea of a Bond-like laser in my skis!
