820 feet long 'Orcelle' is shorter than the Queen Mary 2 (1,132ft) and the QE2 (963ft). The ship is called the E/S Orcelle after the Orcelle Dolphin - the French word for Irrawaddy dolphin, one of the world's most critically endangered species. The E/S stands for "environmentally sound ship". The vessel will include a cargo deck the size of 14 football pitches.



Wave energy is to be harnessed by 12 dolphin like fins an the ships hull. While, sun and wind energy is collected by three giant rigid wingsails, also covered in solar panels.



The cruise speed is in the region of 15 knots. Stability is provided by the shape of the Pentamaran hull - a slim monohull that will have two smaller support hulls know as sponsons on each side. You may recognise this layout as a Trimaran, or stabilised monohull (see Solar Navigator) in that there are essentially, three hull components in contact with the water.



very interesting design even tho right now its only a concept. Here's another article that will catch your attention.

WASHINGTON, DC – U.S. Department of Energy (DOE) Assistant Secretary for Energy Efficiency and Renewable Energy Alexander Karsner today announced that with DOE funding, a concentrator solar cell produced by Boeing-Spectrolab has recently achieved a world-record conversion efficiency of 40.7 percent, establishing a new milestone in sunlight-to-electricity performance. This breakthrough may lead to systems with an installation cost of only $3 per watt, producing electricity at a cost of 8-10 cents per kilowatt/hour, making solar electricity a more cost-competitive and integral part of our nation’s energy mix.

“Reaching this milestone heralds a great achievement for the Department of Energy and for solar energy engineering worldwide,” Assistant Secretary Karsner said. “We are eager to see this accomplishment translate into the marketplace as soon as possible, which has the potential to help reduce our nation’s reliance on imported oil and increase our energy security.”

Attaining a 40 percent efficient concentrating solar cell means having another technology pathway for producing cost-effective solar electricity. Almost all of today’s solar cell modules do not concentrate sunlight but use only what the sun produces naturally, what researchers call “one sun insolation,” which achieves an efficiency of 12 to 18 percent. However, by using an optical concentrator, sunlight intensity can be increased, squeezing more electricity out of a single solar cell.

The 40.7 percent cell was developed using a unique structure called a multi-junction solar cell. This type of cell achieves a higher efficiency by capturing more of the solar spectrum. In a multi-junction cell, individual cells are made of layers, where each layer captures part of the sunlight passing through the cell. This allows the cell to get more energy from the sun’s light.




That right their is incredible with technology like that, it would be possible for this concept to succeed. In fact right now their is a boat called the sun 21 that has crossed the Atlantic on solar power alone.

I have looked all over the internet and have not been able to find any US naval warship projects having to do with solar, tidal, or wind power. I would think that the navy would be incredibly interested in this technology and be pursuing it. Does anybody have any more information on this? Any other articles to contribuit?

Personally i think its a bad idea to have solar or wind powered ships because is someone hits the solar panal or the wind mill (Not sure what to call it) wouldnt it strand the ship at sea.
