This Great Lakes Island Wants to Power Up With Waves

Imagine living on an island in northern Lake Michigan, roughly the size of San Francisco, where your power comes from a 30-mile underwater extension cord. Sounds charming, until a nasty ice storm — or just a Tuesday — cuts that cord, plunging 600 year-round residents into darkness for weeks. Welcome to Beaver Island.

Turns out, relying on a delicate, submerged lifeline for electricity isn't exactly a recipe for reliability. So, some residents decided it was time to look for power closer to home. And by closer, we mean right there, in the very waves that lap their shores.

The "Ideal Experimental Bathtub"

Recently, researchers from the University of Michigan arrived on Beaver Island armed with two prototype devices. Picture small, PVC-pipe boats, about the size of a yoga ball, bobbing in the water, turning the lake's sloshing energy into actual electricity. These little wave-harnessers successfully powered a light bulb and even charged a cell phone. Because apparently, that's where we are now: the waves are charging your phone.

This isn't just about keeping the lights on for summer tourists. The community, working closely with lead researcher Lei Zuo, emphasized the critical need for dependable power, especially for the airport. This project is part of a broader national push to bring stable, alternative energy to remote communities who are tired of being at the mercy of distant grids or temperamental weather. They're not alone; places like Galena, Alaska, and Adjuntas, Puerto Rico, are already building their own solar and biomass solutions.

Seamus Norgaard, a summer resident, put it plainly: it’s about saving money, achieving independence from the mainland, and, you know, not actively destroying the planet while doing it. Which, if you think about it, is a pretty solid trifecta.

Now, wave power isn't without its quirks. It's still a nascent field, expensive, and lacking a standardized design. Most U.S. projects rely on federal grants, like the National Science Foundation money funding the Michigan experiment. But here's a fun twist: marine energy, tucked under the umbrella of hydropower, surprisingly found favor with the Trump administration, which prioritized it for fast-tracking and support. The Department of Energy is even pouring $220 million into continued research.

While ocean waves are generally bigger and more consistent, the Great Lakes offer a unique advantage. Saeid Bayat from the University of Michigan calls them an "ideal experimental bathtub." They provide real-world wave conditions that are easier, safer, and cheaper to access than most ocean sites, allowing researchers to refine the tech before it hits the big leagues.

The team plans to install a final version on Beaver Island in the coming years. And for residents like Norgaard, the prospect of cleaner, locally produced, and undeniably more dependable energy sources is, quite literally, electrifying. No more waiting for the mainland to pick up the phone.
