Limited water availability has regulators, water management districts and municipalities looking for drought-proof, reliable water supplies. Seawater desalination is a technically viable solution to the water shortages in the United States; however, this technical viability has to be considered along with the water costs associated with the treatment of seawater. Seawater typically has a feed water total dissolved solids (TDS) content of 35,000 mg/L. This translates into a higher feed pressure, as well as more expensive materials of construction for treatment systems.

With continuing State support , energy from the sea could be key to our economic future
IT’S KNOWN as the “Nokia” factor. Just as the mobile phone manufacturer is credited with rescuing Finland from its economic difficulties in the early 1990s, so ocean energy has been identified as a potential “lifebelt” for Ireland.
Ireland, Scotland and the southern ocean in Antarctica have some of the most energetic wave locations on the globe – “but we don’t want to be just watching others take advantage of that, while we supply the sandwiches out to the guys on the rig”, says Sustainable Energy Ireland’s (SEI) Eoin Sweeney. |

Inclined-Plate Lamellas Increase Water Treatment Efficiency for English City
By Steve Minett, PhD
A city in the north of England needed to increase its drinking water supply and decided to achieve this by upgrading an existing treatment plant. A more traditional/conventional method of sludge settlement was replaced by Nordic Water’s Lamellas, leading to very considerable increases in efficiencies of maintenance and operation. |

Diesel engine – unparalleled efficiency in the hunt to cut emissions
The environmental demands on trucks are becoming steadily tougher and already this autumn, emissions will be toughened still further in Europe. Pressure for the development of environmentally optimised technology is increasing, but the answer need not lie solely with electric and hybrid solutions. Tomorrow’s most energy-efficient engines are already more than a hundred years old. All the indicators are that the diesel engine still has a lot to give. |

New low-emission truck engine
Truck maker Scania can now satisfy the EU’s new exhaust directive better than competitors thanks to SEM’s skills and Höganäs’ SMC powder.
Scania has followed its own path towards satisfying new EU and US truck emission directives. Instead of cleaning emissions on their way out from engines using various types of catalytic converter, the Company chose to build a new engine that uses fuel more efficiently, generating less emissions in the ignition process. |

TransAlta Corp ., Canada’s largest investor-owned power producer, won a pledge from the Alberta and Canadian governments to support a carbon-capture project.
Alberta has signed a letter of intent with Calgary-based TransAlta to invest C$431 million ($420 million) over 15 years to capture carbon dioxide at the company’s Keephills 3 coal- fired power plant west of Edmonton, the province said in an e- mailed statement today. The carbon dioxide will be used for enhanced oil recovery in fields nearby or stored underground. |

Over the years , we have come to expect great things from the Lotus Engineering team, which they have been more than able to provide. The research and development they accomplish has been used in a myriad of applications extending far beyond their automotive realm. Recently, they unveiled a new range extending motor that will most likely follow the same path of global application. |

Advanced Storage Battery Market : from Hybrid Electric Vehicles to Cell Phones report ( http://www.bharatbook.com/Market-Research-Reports/Advanced-Storage-Battery-Market-from-Hybrid-Electric-Vehicles-to-Cell-Phones.html ) assess Whether it is a battery for the latest laptop, energy storage for a hybrid electric vehicle, or backup power for a remote telecommunications site, everyone wants a battery that has the highest energy density, best safety factor, and longest life in term of discharge cycles and ease of maintenance while still being environmentally friendly. These are the drivers behind rechargeable battery research around the world today. Rechargeable batteries, also known as storage batteries, are a continuing strong market, with worldwide sales of $36 billion in 2008. The rechargeable battery market will rise to $51 billion by 2013. Lithium-ion is the battery chemistry of choice for future generations of portable electronics and hybrid and plug-in hybrid electric vehicles. In 2008, lithium-ion battery research had more funding than all other battery technologies combined. Nanotechnology and chemistry advances in electrode design are the key research topics that companies are using to push lithium-ion to be the dominant energy storage technology in the future.

The wheel turns full circle - but with more sophisticated engineering Energy Secretary Steven Chu is an accomplished scientist, but he's apparently happy to use low-tech home energy-efficiency tricks, too.
Chu was one of the featured speakers at the opening ceremony of the Solar Decathlon, a contest among 20 colleges to create the best solar-powered home. Student teams from the U.S., Canada, and Europe build homes powered only by solar energy and reconstruct them on the National Mall where they are judged in ten categories and opened to the public for viewing. |

GE says it has acquired ScanWind, a developer of advanced gearbox-free drive trains aimed at offshore deployment. The company manufacturers and markets direct-drive wind turbines from its headquarters in Trondheim, Norway and a design-engineering center in Karlstad, Sweden. Direct drives connect the rotor to a generator that operates at low rotational speeds creating a simpler and more reliable drive train. The company has 11 of the turbines operating on the Norwegian coast.
