  • I had to google it, undergrad dissertation apparently means bachelor thesis. It’s a joke to give a bachelor thesis the same name as a real dissertation.

    First off: nobody will cite a bachelor thesis in a well regarded publication. In fact, even real dissertations will rarely be cited. They are not considered peer-reviewed. If you can write a paper based on your thesis and get it accepted at a journal or conference, that’s where you get citations. Usually, that requires a major overhaul of the thesis, though. This definitely requires a support network in the form of a research group. Look into what your university is researching and contact the research groups that look interesting to you.





  • They are all enabling drug cartels, so no, none of them are good. We can’t go around and say companies if not by law are at least morally responsible for child labour and forced labour camps in their supply chain and at the same time ignore that every fucking dealer gets their shit from sources that do the very same thing. There might be exceptions for some drugs, I’m not that deep into it, but in general there is no moral way to sell illegal drugs.







  • There are definitely use cases for battery-electric trains:

    • We have these in Germany usually in areas with low traffic. E.g. if a train line is only serviced a couple of times a day, it’s more cost-effective to carry the batteries with you than to electrify the line.
    • Another use case are train ferries. They are the reason why Germany also had Diesel-powered high-speed trains for a while.
    • Another challenge in Europe is the lack of harmonization of power supplies of train lines between countries. In cross-border traffic, trains have to be adapted to work with different energy supplies. Battery-electric trains can add flexibility for these scenarios. E.g. Germany uses AC 15 kV 16.7Hz, the Netherlands DC 1.5 kV on low-speed and AC 25 kV 50Hz on high-speed lines. When a train goes from the Netherlands to Germany, it disconnects from the Dutch system and reconnects to the German system on the fly. For a moment in between, the train loses power. If the train lacks momentum or has to stop unexpectedly, the train is stranded and has to be pushed over the border by another train that is independent of the power supply.
