SkySails' Ship-Propelling Kites Get a Customer in Cargill

We've written a few times about the fuel-reducing power of the ship-propelling SkySail kites.  In trial runs, the large sails, which are mounted to the front of container ships, have been able to cut fuel use by 20 percent and the company says that the levitra pharmacy in india sails could cut fuel use by up to viagra cost 35 percent in real-world applications.

Now SkySails has a major customer in Cargill, a shipping company that transports more than 185 million tons of goods each year.  Cargill doesn't own any ships themselves, but the companyhas signed a contract with SkySails to test a kite on one of the handysize vessels that it operates through an agreement with the ship's owner.  The handysize vessel weighs in at 25,000 to 30,000 tons, which means it will be the largest ship so far to be propelled by a kite.

The SkySail system should be outfitted on the ship by early 2012 and if all goes well, Cargill will make a larger order.  A study by the United Nations International Maritime Organization found that use of SkySails on ships worldwide could reduce shipping CO2 emissions by 100 million tons a year.  Let's hope more large ships will be outfitted with this technology soon.

Drastic New Reduction in Power Conversion Losses


What if your laptop no longer needed a converter brick? What if the DC power from your solar panels was converted to AC electricity with virtually no power loss from the generic cialis buy online conversion? What if the regenerative brakes in electric drive vehicles could put power into the batteries with almost no loss from power conversion? New technology could reduce power conversion losses by an estimated 90 percent.

A company called Transphorm, whose investors include Google Ventures and Kleiner Perkins and which was recipient of cheapest place to buy viagra a significant ARPA-E grant to develop this technology, is poised to introduce their initial product offerings which can significantly improve power conversion. The technology is based on using gallium nitride instead of traditional components to greatly reduce the energy losses in power conversion.

The technology for these new devices is based on developments for the use of gallium nitride for LEDs. In addition to the significant improvement in efficiency, components made in this fashion would also be lighter than conventional converters.

Not only would this be useful for laptop computers, but many renewable energy production systems such as solar photovoltaics and wind turbines would also see an efficiency improvement of a few percent over current systems. It might not seem like much, but the long term benefits of this, multiplied over billions of devices, could be hugely significant. As the company points out, "More than 10% of all electricity is ultimately lost due to conversion inefficiencies. The scale of this loss exceeds the world's entire supply of renewable generation by an order of levitra for sale magnitude." Even if this company can address all of that, it will still take many years to overcome the current stock of less efficient converters.

Maersk Orders 10 of the World's "Greenest" Container Ships

Shipping company Maersk has is making great strides towards reducing the emissions of its fleet.  Since 2007, the company has already reduced its emissions per ship by 17 percent and generic viagra in india with a new order for 10 of the most efficient container ships to date, the company is levitra overnight delivery well on sale online viagra ie its way to achieving its goal of a 25 percent reduction by 2020.

The new ship built by Daewoo Shipbuilding & Marine Engineering company and called the cialis pills cheapest price worldwide Triple-E, emits half the carbon of the industry average for its class of container ship and 20 percent less carbon than the current title-holder, the Emma Maersk.

The ship is expected to use 35 percent less fuel than smaller ships.  The ship is larger than the Emma Maersk, but has a slower top speed to increase the fuel economy.  Other efficiency features include a waste heat recovery system that reduces fuel use and CO2 emissions by 9 percent and the ability for sulphur-scrubbers to recommended site buying levitra online be fitted to the ship.

The ship was also designed to be 90 percent recyclable.  A so-called "passport" outlines and locates every component used in the ship so that all of the materials can be easily reused in future vessels.

The $190 million ships will start traveling between Asia and Europe in 2013 and the contract with Daewoo allows for 20 more ships to be ordered in the future.

Obama Administration Investing $53 Billion in High Speed Rail

Yesterday, Vice President Joe Biden announced that the Obama administration is investing $53 billion in high speed rail development over the next six years.

The money will go towards building new high speed rail corridors and outfitting existing lines for high speed.  In the State of generic cialis cheap the Union address, the president discussed his desire to give 80 percent of Americans access to high speed rail by 2025 and it looks like he's ready to get moving on that goal.

The administration already dedicated over $8 billion for high speed rail development in the stimulus package, but this new announcement is a much bigger commitment to making it a reality.

The details of the plan should be announced next week, but 11 major corridors have already been identified by the administration as optimum routes for high speed rail.  A similar, but more extensive plan was unveiled by the US High Speed Rail Association last year.

Bloom Energy Offering 10-Year Electricity Contracts

Bloom Energy is now offering companies 10-year electricity contracts for its Bloom Box fuel cells, without an upfront payment for the Bloom Box itself, which can cost up to $800,000.

Companies like Walmart, Staples, Coca-Cola, Caltech, Kaiser Permanente and BD have already signed up for the program called "Bloom Electrons" that promises cleaner electricity at prices lower than standard power from the grid.  Lux Research has done the math and figured with government incentives and subsidies, the cost of electricity from a Bloom Box over ten years would come out to $0.08/kWh to $0.10/kWh compared to visit web site non prescription cialis the average retail electricity costs of about $0.11/kWh, but in states without heavy subsidies, the costs would be more expensive at $0.13/kWh to $0.14/kWh.

The Bloom Box fuel cell uses methane from natural gas or biogas to produce electricity.  Check out our previous posts on Bloom Energy for all the cialis online fda details.
