⛵ He built a solar-powered yacht for about $20,000 — then took it across Europe to prove it could go the distance. Finnish engineer Lukas Sjöman spent roughly 200 days building Helios 11, a DIY electric yacht made from marine plywood and fiberglass. Instead of relying on gasoline or diesel, the boat uses rooftop solar panels, batteries, and a 6 kW electric motor. With good sunlight, it can cruise at around 7 knots and reportedly cover up to 270 kilometers in a day. Even when conditions aren't ideal, it can still manage around 70 kilometers. But the impressive part came after the build. Sjöman took Helios 11 on a journey of more than 3,000 nautical miles — roughly 5,700 kilometers — from Finland to Ibiza, Spain. And the entire trip was completed without burning fuel. The batteries were charged by the sun, while the electric motor kept the yacht moving. A $20,000 DIY boat powered almost entirely by sunlight — and tested on a journey thousands of miles long. ☀️⛵ 👉👉Follow aiupdate...
