Fazit
- Bei der Qualität hebt sich Barilla kaum von der Konkurrenz ab. Im Labor wie alle anderen Nudeln top, geschmacklich landeten die beliebten Pasta in unserer großen Blindverkostung aber auf dem letzten Platz.
- Das Unternehmen ist beim Nachhaltigkeitsthema dank Zugtransport und spezieller Weizenzüchtungen für Vertragsbauern auf dem richtigen Weg. Bis zum Ziel einer komplett nachhaltigen Produktion ist es aber noch weit.
It’s a non-issue meant to deflect from real problems. It’s also summer, so there’s nothing going on and the news are blowing everything out of proportion.

Germany’s constitution protects certain parts from changed through regular legislation. This was done specifically to prohibit the rise of authoritarian governments.

That’s not how orbits work. You can’t just point at the sun, accelerate slowly for 10 seconds and then you will arrive in a few hundred years. If you did that, you would still orbit the sun, just in a slightly different orbit than before. To actually reach it or get near enough to it that the junk burns off, you have to expend a lot of energy.
Numerphile hat dazu vor einiger Zeit zwei Videos veröffentlicht, welche das ganze schön illustriert wird. Der Channel ist generell sehr zu empfehlen:

If you have a large stream of people constantly entering or leaving the building, both doors will be open all the time. In a rotating door, people can enter and exit simultaneously and constantly but you still have a working air lock that exchanges less air with the outside than a door that is open all the time.
As he mentions in the video, the field is lagging behind other (renewable) energy sources by a few decades. Many of our energy production methods are “make thing spin fast” and then turn that energy into electricity. Coal power plants burn coal, create steam, the steam drives a steam turbine and the turbine a generator. A nuclear plant works the same way, just by extracting heat from fission instead of burning the fuel. Wind turbines, too. The technologies for this, like metal forging and casting, handling of steam, steam engines and turbines have been around for a long time and we have become experts in them. Solar panels are an exception to this as they used a different mechanism to generate electricity. Nevertheless, all of these technologies can be safely developed and deployed on land. Handling harsh marine environments up to a point where you can reliably drive these generators for an extended period of time just doesn’t exist yet. Historically speaking, this has not been necessary. So not only have to figure out how to best design wave energy extractors, we also need to get better at adapting them to the environment.
