UK Dyson Award Winner Triumphs With "Multi-Axis Wave Energy Converter"

By Gary Cutlack on at

This year's Dyson Award winner from the UK category is Sam Etherington from Brunel University, who took it upon himself to casually invent a better method of generating electricity from the relentless action of the sea's waves.

Current wave energy machines with their rubbish old single axis systems are only able to capture energy from sea movements in one direction, whereas this one can absorb forces from multiple directions, better tracking the three-dimensional shapes of those unpredictable waves. So is better. Here's how it works:

"The cylinders housing Sam’s device ride the peaks and troughs of the waves. This in turn spins a concentric shaft. These work in pairs to push and pull hydraulic fluid as the unit, similar to the way a piston works. This double action then allows pressure to be created. This hydraulic pressure is then stored in accumulators and released at a capped limit into a hydraulic motor which is mated to a geared generator."

Sam wins himself £2,000 to put toward testing prototypes, plus Samsung will now begin secretly monitoring all of his future emails. Congratulations, Sam. [Dyson Awards]
