Following the sunlight, going into a new era!

Figure 1: Concentrated solar thermal plant [2]

“The harness of waterfalls is the most economical method known for drawing energy from the sun” stated the eclectic inventor Nikola Tesla. Both the Greeks and the Romans had realised that as they were already using hydraulic energy to grind wheat in watermills. This usage continued since up to the point that Western Europe and the United States are now ...

Will we suffocate in our waste?

“Humanity will not perish in an atomic nightmare – it will suffocate in its own waste” said the Nobel Prize winner Niels Bohr. Despite his thoughts that “it is difficult to make predictions, especially about the future”, he could not have been any more right. So are many countries realizing this now. While this has been a global issue for ...

In my previous blog post here, I talk about how circular economy works and how my Ph.D. works will contribute to achieving this emerging framework. In specific, producing hydrogen from gasification of landfill waste, and later on, using it as a fuel or chemical feedstock could be the best scenario for closing the economic cycle. Hydrogen has been named as ...

Company visit, data collection, and everything in between

My colleague ESR Giovanna and me keep smiling through our adventure.

“It must be very challenging to try to understand all these chains of processes”, said Daniel, an industrial partner from ScanArc Plasma Technologies AB, as he kindly drove us to the train station after our company visit. In this blog entry, I would like to bring you the perspective of a system analyst battling through one of the most tedious ...

Inversion – a mathematical problem

christin

Okay, the text immediately starts with a problem. It’s a mathematical problem, but it is also in a sense mathematically problematic: it is the so-called inverse problem. We, at Ghent University, work with such inversions almost every day, since their solution allows us to derive valuable results from our geophysical measurements. Let’s start with figuring out what the term ‘inversion‘ ...
