A solar barque is a type of boat designed to harness solar energy for propulsion. These vessels are equipped with solar panels that convert sunlight into electricity, which powers electric motors. Solar barques are often used for recreational purposes, research, or eco-friendly transportation, promoting sustainability on water. The concept of solar barques is inspired by ancient Egyptian solar boats, which were used to transport goods and people along the Nile River. Modern solar barques aim to reduce carbon emissions and reliance on fossil fuels, contributing to a cleaner environment and showcasing advancements in renewable energy technology.
