Physics You've Never Heard Of Provides Power From Waves - Hackaday

“In the future, we’ll be generating a significant fraction of our electricity from harnessing the waves!” People have been saying this for decades, and wave-generated electricity is not a significant fraction of an ant’s poop. It’d be fantastic if this could change. If you believe the owners of Oscilla Power , the main failing of traditional wave-power generators is that they’ve got too many moving parts. Literally. Metal mechanical parts and their seals and so on are beaten down by sun and salt and surf over time, so it’s expensive to maintain most of the generator designs, and they’re just not worth it. Oscilla’s generator, on the other hand, has basically no moving parts because it’s based on magnetostriction , or rather on inverse magnetostriction, the Villari effect . Which brings us to the physics. Magnetostriction is the property that magnetic materials can shrink o...
