The world is entering a new era of instability. The climate crisis will put great pressure on the (relatively) peaceful balance of world politics. But the field of open source intelligence (OSINT) provides us with a new and unique way to map, study and predict these flashpoints. This talk will look at several technical approaches for using these techniques and include several example studies.

Sonnenenergie deckt heute erst etwas über 2% des weltweiten Energiebedarfs durch Umwandlung von Sonnenlicht in elektrische Energie. Eine der Möglichkeiten, um diese zu speichern, ist die Elektrolyse von Wasser, um Wasserstoff zu erhalten. Was aber wäre, wenn man Wasserstoff direkt gewinnen könnte? Eine schnelle Übersicht über Sonnenlicht, das Prinzip hinter Photovoltaischen Solarzeiien, und wie photoelektrochemische Zellen, die flüssiges Wasser in seine Bestandteile Wasserstoff und ...

This talk will give an introduction into the general concepts of power-to-x and then go more into detail on carbon capture and utilization (CCU). CCU is the idea of building up a closed carbon cycle, where CO2 is recycled, towards fuels and base chemicals, under the use of renewable energy. The talk will give insight in the technology, chemistry, possibilities and challenges.

Climate change and the discussion about reducing CO2 emissions to ensure matching the Paris agreement currently is the most important topic in our political and economic discussions. We all agree reducing emissions is a necessity, but how can we possibly achieve this in a world that consumes more energy than ever before? And which price are we willing to pay for it?

To tinker with receivers for space-signals, its good to know the different space communication standards. And to understand space standards, it doesn't hurt to get an overview of how to transmit data in the first place.

The beautifully complex structures often found in Nature arise from the collective interaction of huge numbers of particles moving under very simple forces. Starting from this fact, I will present how we can encode simple physical properties into large scale networks in a way that mimics a physical system and leads to elegant structures in 2d or 3d space. After introducing some basic concepts, a large part of the talk will consist of animated demonstrations of network evolution towards a final ...
