Scientists fear that even before one of the last frontiers of exploration, the ocean deep, has been properly studied it will already have been exploited by commercial deep-sea mining looking for rare euronews knowledge brings you a fresh mix of the world's most interesting know-hows, directly from space and sci-tech experts.

Oceans cover 70 percent of the earth's surface, but only a fraction of the undersea world has been explored. On this episode of TechKnow, Phil Torres joins a team of scientists on a special expedition to explore and uncover the mysteries at the bottom of the ocean floor. "What we are doing is similar to astronauts and planetary scientists just trying to study life on another planet," says Beth Orcutt, a senior research scientist. The journey begins in Costa Rica aboard the R/V Atlantis, a research vessel operated by the Woods Hole Oceanographic Institution. From there, Phil gets the chance to take a dive with Alvin, a deep-water submersible capable of taking explorers down to 6,000 metres (20,000 feet) under the sea. Commissioned in 1964, Alvin has a celebrated history, locating an une...
The world’s first ever deep sea mining operation is scheduled to begin offshore from the Pacific island nation of Papua New Guinea in early 2018. In this short film we explore how the two Pacific Island nations of Papua New Guinea and Vanuatu are working together with their communities to manage the future opportunities and impacts associated with this emerging industry. While deep sea minerals could provide much needed revenue for several Pacific Island nations, questions remain about the impacts of mining on the marine environment and the many communities that depend on it for their livelihoods.
This video shows how colonists make use of modest, pressurized outposts to mine vast deposits of precious minerals on the bottom of the oceanic trench.
The development of the BMT System®, which makes materials containing lignin (like e.g. straw and wooden residues) economically digestible in biogas plants, is an extraordinary success of MWK Bionik® GmbH. For many microorganisms, material containing lignin is difficult or not at all digestible, and thus not used when applying current technologies - it remains as solid fermentation residue. Within the BMT System® bacteria are being used to crack the complex and robust structure of lignocellulose. This video shows LignoX®-bacteria which have already cracked the lignin coating of the straw cells and are now visibly moving inside the cells. This is the visible proof for pre-digestion of lignocellulose. The highly efficient microorganisms and bacteria of LignoX® originate from extreme biotopes ...
Gold became highly concentrated as the result of global forces operating over hundreds of millions of years. Volcanoes, tectonic plates and erosion all combined to concentrate billions of dollars' worth of gold in the mountains of California. During the California Gold Rush, gold-seekers known as "Forty-Niners" retrieved this gold, at first using simple techniques, and then developing more sophisticated techniques, which spread around the world. Geologic evidence indicates that over a span of at least 400 million years, gold that had been widely dispersed in the Earth’s crust became more concentrated by geologic actions into the gold-bearing regions of California. Only gold that is concentrated can be economically recovered. Some 400 million years ago, rocks that would be accreted onto wes...

The natural mineral product MagnaDense provides high density and heavy weight to offshore constructions such as platforms or wind parks ensuring a stable foundation or to keep these floating and stable for wind and sea.
This robotic deepwater seabed geotechnical drill can investigate seabed conditions in up to 3000m (10,000 ft) of water, and bring back sediment core samples from up to 150m (500') in the seabed. It can be used by engineers to help in designing underwater structures for offshore wind farms and oil and gas platforms, as well as exploring the seabed for minerals or scientific research.

During ONS 2008, Andreas B. Larsen from PG stopped to talk to Techni about the linear actuator and its possible use as a pump driver. This talk lead to a joint development project between Ing. Per Gjerdrum and Techni to make a more compact subsea membrane pump. Using the combined knowledge from the pump industry (PG) and the permanent magnet drives (Techni), a new product emerged. The PG-MAPS (Multi Application Pump Solution) was born. Using the solution in a Quad configuration, a ripple free, high volume and high pressure pump was realised. The quad pump is currently (December 2010) under testing at PG's premises in Asker, Norway. http://www.pergjerdrum.no
