The power of salt

MIT study investigates power generation from the meeting of river water and seawater. Where the river meets the sea, there is the potential to harness a significant amount of renewable energy, according to a team of mechanical engineers at MIT.

New study on climate history: Arctic sea ice influenced force of the Gulf Stream

The force of the Gulf Stream was significantly influenced by the sea ice situation in the Fram Strait in the past 30,000 years. Scientists at the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) come to this conclusion in a new study that appears today in the journal Earth and Planetary Science Letters. On the basis of biomarkers in deposits on the seafloor, the geologists involved managed for the first time to reconstruct when and how the marine region between Greenland and Svalbard was covered with ice in the past and in what way the Gulf Stream reacted when the sea ice cover suddenly broke up. They concluded that when large amounts of Arctic ice drifted through the Fram Strait to the North Atlantic, the heat transport of the Gulf Stream declined noticeably.

Record decline of ice sheets

For the first time scientists map elevation changes of Greenlandic and Antarctic glaciers. Researchers from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), have for the first time extensively mapped Greenland’s and Antarctica’s ice sheets with the help of the ESA satellite CryoSat-2 and have thus been able to prove that the ice crusts of both regions momentarily decline at an unprecedented rate. In total the ice sheets are losing around 500 cubic kilometres of ice per year. This ice mass corresponds to a layer that is about 600 metres thick and would stretch out over the entire metropolitan area of Hamburg, Germany's second largest city. The maps and results of this study are published in The Cryosphere, an open access journal of the European Geosciences Union (EGU).

Ways of a new water policy 4/4

A vision for the future: if the Bundestag, i.e. German Parliament, passes a water conservation law that requires builders to install efficient fixtures, promotes private retrofits such as water-saving showers, toilets, washing machines and dishwashers and demands a water penny from large consumers, we will soon consume only half as much water as we do today. Every year 25,000 liters of water per capita would thus be saved, i.e. 250,000 liters in ten years. A family of four would save a million liters of water without sacrificing any comfort.

Water in trouble 3/4

Even in today’s water-rich Central Europe we are heading for a water shortage. Our water is being used, contaminated and wasted. Poison in water, chemical waste, fertilizers and air pollution threaten our most important means of survival.

So water is more than H2O 2/4

All founders of religions, philosophers and wisdom teachers from all periods and civilizations knew about that. The wonderful young man from Nazareth, an ecologist even 2,000 years ago, said, "Truly, truly, I say to you, unless one is born of water and the Spirit he cannot enter into the kingdom of God.” Responsible handling of water is religious service. And to those who wanted to follow him, ecologically-minded Jesus called out; “Be springs of living water.” He did not speak of impure or contaminated water. Parson Kneipp taught in the 19th century: “Aqua sanat – water heals!“
