Ethanol fireplaces: the underestimated risk

Ethanol fireplaces are becoming more and more popular. However, they are not only highly combustible – in the past, severe accents have occurred repeatedly with decorative fireplaces. The devices also pollute the air in the rooms. This has been proven by a recent Fraunhofer study. Wood-burning ovens are also on the testing block.

Researchers observe the phenomenon of "lithium plating" during the charging process

Live from inside a battery. Lithium-ion batteries are seen as a solution for energy storage of the future and have become indispensible, especially in electromobility. Their key advantage is that they are able to store large amounts of energy but are still comparatively light and compact. However, when metallic lithium forms and deposits during charging it can lead to a reduced battery lifespan and even short-circuits. Scientists at the Technische Universität München (TUM) have now managed to peer into the inner workings of a battery without destroying it. In the process, they have resolved the so-called lithium plating mystery.

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.

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!“
