Environmental and Life Cycle No-one will deny that the environment is an important factor to consider when doing anything these days. Engineers are the ones largely coming up with the solutions.

The winner of the extremely exciting Re:Vision Dallas competition to create a completely sustainable community on a run-down city block in downtown Dallas was just announced yesterday – and it’s incredible! “Fowarding Dallas,” submitted by Portuguese-based architectural firms Atelier Data and Moov took the grand prize with their hillside-inspired design that consists of a series of peaks and valleys, runs completely on renewable energy, is covered in vegetation, and can even grow its own food. The coolest part? This mixed-use eco-community won’t just a concept – it will actually be constructed in Dallas in 2011! |

How can a wind-turbine OEM as well as their countless suppliers squeeze more power from the wind using already well developed equipment? Even a small efficiency increase would be welcome. The viability of the business depends on it.
The wind business is also counting on such gains to improve returns on investment, especially in times of economic uncertainly and the heighten demand for green energy. |

The ocean is a potentially vast source of electric power, yet wave-energy systems are rare as they generally offer limited efficiency, must withstand battering storms, and need to be tethered to the sea floor. But by applying the principles that keep airplanes aloft, a team of aerospace engineers is creating a new wave energy system that is durable, extremely efficient, and can be placed anywhere on the ocean, regardless of depth. |

Russian scientists developed a technology, which provides plasma processing of solid wastes into motor fuel components without emitting any toxic or hazardous substances.
Nowadays the most widely used technology for disposing of solid wastes is burning natural gas (or other combustible gases) in fluid-bed facilities under temperature of 850 degrees Centigrade. This burning temperature is relatively low, thus causing formation of extremely dangerous poisons, such as dioxins (p-dibenzodioxins) and furans (p-dibenzofurans), which concentrations in off gases may vary between 7000-45000 nanograms per cubic metre, while European Union standards provide a maximum of 0.1 nanograms per cubic metre. Apart from dioxins and furans, off gases may contain other substances, which can harm human health – aldehydes, phenols, volatile metal compounds and etc. Refuse incinerators have some techniques to get rid of aforementioned substances, but they require expensive components |

A new British-Dutch design for a deep sea turbine foundation that features a 'suction bucket' tripod has been shortlisted in a multi-million pound competition aimed at slashing the escalating costs of offshore wind installations in the UK.
The unique tripod concept features three up-turned bucket like structures that are 'sucked' into the soft sea bed, thereby doing away with 'pile driving', which has cost, speed, and environmental disadvantages. The asymmetric design, meanwhile, means the entire structure can be efficiently assembled quayside and transported to the site with the turbine already installed, avoiding the cost of installation cranes. The design is the work of Netherlands-UK partnership, Suction Pile Technology and Wood Group. |

A VISITING US expert on Monday underscored the importance of applying the “precautionary principle” (PP) to ensure a toxic-free and life-sustaining environment to protect people and the environment from harm.
Paul Connett, a specialist on environmental chemistry and toxicology who has gone to 52 countries promoting zero waste and chemical safety, told participants to a seminar on toxicology at the Occupational Safety and Health Center in Quezon City that precautionary measures should be taken whenever an activity raises threats of harm to the environment or human health “even if some cause-and-effect relationships are not fully established scientifically.” |

Americans have been burning coal for electricity for roughly 130 years with little understanding of what the process leaves behind. But before the end of the year, the federal government will decide whether the leftover ash from the coal-burning process should be considered a hazardous substance. |

The Middle East’s water supply depends heavily on the issue of wastewater reuse.
At a break-out session held during Frost & Sullivan’s recent Growth, Innovation and Leadership (GIL) Conference held in Abu Dhabi in September, senior figures from the region’s water industry were asked to list the most important issues that were currently prevalent in the wastewater sector.

When the campus placements happen in 2011 at IIT Kharagpur, these five students will give it a miss. They would have by then started their own company. They have developed a bio cell' (battery) that can not only treat sewage water but also generate electricity a that could offer a one-stop solution to the water and energy crises.

Solar manufacturing processes today commonly start as research and ramp up slowly to full production. Though software is not a major direct cost, it can have major effects on ramp time. Delays from enhancing or fixing control and automation software can stop floor progress for days at a time. A production line cannot tolerate unnecessary delays for software modifications. For these reasons, software for solar manufacturing must be agile in the purest sense: quick to evolve, yet reliable as soon as it arrives on the factory floor.

Engineers at the UC San Diego are developing control systems for herds of tiny robotic ocean explorers which might one day assist in predicting where ocean currents will carry oil spills. Researchers at Scripps Institution of Oceanography and the Department of Mechanical and Aerospace Engineering at UC San Diego are developing the underwater robotic ocean drifters. The autonomous robots are intended to help find and describe underwater ocean currents on the order of a few kilometres. Such currents are not well understood, yet they are important to the understanding of marine protected areas, algal blooms, oil spills, and the path sewage takes after it is pumped into the ocean. |

HONOLULU—The plan to pump frigid waters from the ocean's depths to air condition downtown Honolulu isn't a pipe dream, and it could reduce the state's dependence on fossil fuels while slashing power bills that are the highest in the nation.
The long-studied cooling project by Honolulu Seawater Air Conditioning would extend plumbing nearly 5 miles offshore, suck 45-degree water from 1,800 feet deep, circulate frosty water into buildings' existing A/C systems and then dump it back into the sea. |

Danish engineering group Ramboll has been commissioned to design a laboratory facility for testing the performance of full-scale building elements, as part of Bergen University College's research on sustainable building methods. In addition to being a laboratory, the facility, which is generally referred to as "the Climate House", will be used as a public showroom for the sustainable technical solutions that are already available in the market today. |
