And since this boat runs solely on the sun, there are no fuel costs. The PlanetSolar ship has been designed to be the first ship to make a round-the-world journey on solar power, and plans to set off in April of 2011. At 9 mph, the trip will take approximately 140 days of solar sailing, not counting stops at Hamburg, London, Paris, New York, San Francisco, Singapore, and Abu Dhabi along the way.] The PlanetSolar is actually a catamaran, meaning it has more than one hull. This design no doubt helps the ship slip through the water with ease and maintain stability. Weighing in at 60 tons and over 100 ft long, with solar panels covering most of the ship, it can supposedly capture over 100 kw of energy, even though its engine needs just 20 kw to drive the ship. How much does this technology cost? Oh, about $24 million. The ship was designed by a Swiss man named Raphael Domjan, who will captain the ship on its journey. There will be just one other crewman on board, G�rard d�Aboville, a famous French mariner.
From: habshi on 26 Feb 2010 17:26 Guaranteed food prices for farmers have lead to surpluses in USA and Europe , and feed in tarriffs will do the same for renewable energy and lead to everlasting prosperity excerpt According to data accumulated by the Japan Photovoltaic Energy Association (JPEA), 1.39-gigawatts worth of solar panels were sold in 2009. This total not only represents a 21% increase from 2008 installations, but also the largest amount of sales ever recorded by the JPEA. Last year, domestic sales more than doubled (483.96-megawatts); this can be attributed to two significant federal policies. In April, the federal government reintroduced subsidies for households that install solar panels; and, in September, the government introduced a solar feed-in tariff that requires utilities to buy the surplus energy supplied to the grid from solar panels on houses and businesses. With the new feed-in tariff law, utilities are paying twice what they used to pay for solar energy. Through government incentives, solar power has become a lucrative investment. In Tokyo, for example, federal and local subsidies can amount to almost 270,000 yen (US$3,001) per kilowatt. It is estimated that household and business solar panel installation costs between 600,000 yen (US$6,670) and 700,000 yen (US$7,781) per kilowatt. This means solar panels are providing Japanese investors with an incredible 38.5% return on investment. In its desire to lower its greenhouse gas emissions to 25% below its 1990 levels by 2020, the Japanese government is planning to extend its feed-in tariff program to other clean energy sectors including wind power .... The rebate program, which is designed to encourage California residents and businesses to install solar water heaters, coupled with the 30% Federal Tax Credit, will allow Californians to purchase solar water heaters at 60% off their retail price. Average rebates for installations at single-family homes will be around $1,500, while commercial and multi-family properties are eligible for much larger rebates. The program will either run until 2017 or until the funds are exhausted. CPUC's goal is that the program will lead to the installation of 300,000 solar water heaters in the next eight years. Solar water heaters are more energy efficient and obviously more environmentally friendly than gas-powered water .... Six new geothermal energy projects came online in 2009, despite the persistent global economic struggles. These six projects increased U.S. geothermal capacity by 6%. On the whole, geothermal projects take 3-5 years to develop, and if all the new geothermal projects prove successful, they will increase the United States geothermal capacity to 10 GW--enough to supply 25% of California's electric demand.

Yet another toy. -- Jim Pennino Remove .spam.sux to reply.
From: habshi on 26 Feb 2010 17:57 You missed the main point , that a 60 tonne ship needs just 20kw of power . Even a fridge sized bloom box can supply 100kw. And a 100kw windmill could easily be put on any ship. A jumbo elephant weight windmill can supply 1,000 Kw enough for the largest container ship

Your solar "cargo" ship has no place to put cargo. Powering a ship with a windmill is only done in cartoons. -- Jim Pennino Remove .spam.sux to reply. |
