World’s Largest Solar-Powered Boat

The TURANOR PlanetSolar, the world’s largest solar-powered boat, has just completed the first stage of its journey around the world – a trans-Atlantic journey from Monaco to Miami. The Swiss-designed solar-powered catamaran left Monaco on the 27th of September and docked in Miami just a few days ago, on the 28th of November. More after the break...

At 101.7ft (31 meters) long and 49.2ft (15 meters) wide, the TÛRANOR PlanetSolar is the world’s largest solar-powered boat. The vessel is completely fuelled by renewable energy, with its solar cells having a 22% efficiency rate. These are the highest rated cells available for purchase on the market, and the cells cover over 500 square meters of the ship. The solar cells are able to power two electric motors which are found in the hull, giving the ship at a top speed of 14 knots. Most notably, the large surface area of solar cells means that the catamaran can travel for up to three full days, even without direct sunlight – any excess energy is stored in a state-of-the-art lithium-ion battery.

After this layover in Miami, the TÛRANOR PlanetSolar will head to Cancún, Mexico for the United Nations Framework Convention on Climate Change, where it will participate in activities organized by the Swiss government. The vessel is then expected to fully circumnavigate the world in the coming months, visiting San Francisco, Sydney, Singapore and Abu Dhabi, before returning home to Monaco.

The multi-national crew of the ship include Frenchman Patrick Marchesseau (Captain), Christian Ochsenbein (Bern, Switzerland), Michaela von Koskull (Finland), Jens Langwasser (Kiel, Germany) and project initiator Raphael Domjan (Yverdon-les Bain, Switzerland).

 

Largest Wooden Sculpture in the World

The power of a wood structure is defined in a striking new edifice. A wood canopy of six "parasols" has been erected in Seville, Spain. Completed last month, it was designed by Berlin architect J. Mayer H., with timber construction by Finnforest-Merk GmbH, Aichach. Metropol Parasol, is it is formally known, is built of 3,400 wooden parts, is over 90 feet tall almost 500 feet long. 16 More images after the break...

The structure is made of  interlocking pieces of wood  held together mostly with glue and with metal clamps. Costing an estimated 130 million Euros and built over the course of five years, the structure is designed as an urban icon to draw attention to Seville, and reclaim an underutilized urban area. Restaurants and shops are embedded in the towers and below the canopy. A view walkway crowns the top. Architect Mayer designed it as an entry in a competition in 2004. Mayer describes it:

 The Metropol Parasol scheme with its impressive timber structures offers an archaeological museum, a farmers market, an elevated plaza, multiple bars and restaurants underneath and inside the parasols, as well as a panorama terrace on the very top of the parasols. Realized as one of the largest and most innovative bonded timber-constructions with a polyurethane coating, the parasols grow out of the archaeological excavation site into a contemporary landmark, defining a unique relationship between the historical and the contemporary city.
