PlanetSolar is a multli-hull vessel topped by a large array of photovoltaic solar panels, constructed by Knierim Yacht Club, in Kiel, Germany. Currently at the design stage, it will be a boat of impressive proportions, and yet it will be both silent and clean. The goal is to navigate around the world at an average speed of 8 knots — no mean feat for a solar-powered craft.
The ideal shape and size of the boat for the chosen route has been determined by in-depth research, with PlanetSolar engineers having to factor in a host of parameters — propulsion, solar panel design, energy storage, materials, and the external environment. A whole range of studies was needed in areas such as the boat's hydro and aerodynamics, the materials used, the management and storage of energy and, finally, the power plant and the optimal routing.
The multi-hull measuring 29.87 metres long, 15 metres wide and 34.7 high, will weigh 60 tonnes and will support 470 square metres of PV solar panels. It will be home to two sailors during the round-the-world attempt and can accommodate up to fifty people during the promotional trips planned at each port of call.
This unprecedented endeavour, aimed notably at promoting hybrid vehicle technology, should help to bring about a change in mindsets. If it succeeds, it will spawn technological developments in many fields, such as the manufacture of composite materials and structures or the generation and storage of photovoltaic energy (or electricity).
“It is now time to demonstrate the potential that renewable energies have to offer in the area of mobility”, said PlanetSolar. “Preserving our planet by promoting solar energy, energy efficiency and sustainable mobility is therefore what this project is all about. This represents a tremendous opportunity to inform the general public and heighten their awareness of the importance of renewable energies.”
PlanetSolar will embark from Marseille, crossing the Atlantic to the Panama Canal, where it will then traverse the Pacific. Subsequently, it will cross the South China Sea, the Indian Ocean and the Red Sea, before travelling through the Suez Canal on its return to the Mediterranean.
Ports of call will include New York, Miami, San Francisco, Shanghai, Singapore, Abu Dhabi and Carns. Meanwhile, anyone interested in seeing the prototype in person can do so between 3 and 5 September at the PlanetSolar Village in Yverdon-les-Bains, located close to the Swiss city of Lausanne.
