South Korea Ferry Cleans 100 Tons of Water While You Ride

Imagine riding a ferry that cleans the water beneath you while powered entirely by the sun. South Korea startup Ecopeace just made that dream real with the Healing Boat, an autonomous ferry that purifies up to 100 tons of water per day while carrying eight passengers on guided tours.

The company already developed the Eco-Bot, an AI-powered solar boat that removes floating pollutants, oil spills, and harmful algae blooms that can kill fish and threaten human health. These autonomous cleaners collect water quality data across lakes, rivers, and reservoirs, helping cities understand and manage their waterways better.

But the Healing Boat takes this technology further by making water purification visible and engaging. By day, it offers 30-minute guided tours of local freshwater facilities, teaching visitors about water systems and local ecology. At night, guests can enjoy food truck tours and fireworks displays, all while the boat continuously cleans the water below.

The concept flips traditional environmental infrastructure on its head. Water treatment typically happens out of sight, making it feel like an expensive maintenance cost rather than a public benefit. Ecopeace wanted to change that perception entirely.

"Because purification happens in a visible, citizen-facing way, it becomes easier for agencies to explain why environmental investment matters," the company explained. Visitors can even explore underwater ecosystems through 3D digital video content, connecting them directly to conservation efforts simply by boarding the boat.

The innovation earned a 2025 CES Innovation Award in the Smart City category, bringing international attention to the design. The company already operates across South Korea and Southeast Asia, with plans to expand to any cities with large waterfront spaces.

The Ripple Effect

The Healing Boat shows how smart design can turn invisible infrastructure into community experiences. When people see environmental protection happening in real time, they understand its value differently. Cities gain both cleaner water and stronger public support for sustainability investments.

The technology also protects local wildlife with slow-moving guards that keep ducks and birds safe. Ecopeace's solar-powered systems need more global exposure to spread worldwide, but the model proves that environmental solutions don't have to stay hidden in the background.

Water management is evolving beyond treatment equipment alone into something that creates visible public value while improving the environment everyone shares.
