if all the knowledge in any topic can be classified in 5 categories from where the highest category is a non-technical article in a news website to the lowest level knowledge being a research paper in topic, which category is a video by Sabine Hossenfelder
Sabine Hossenfelder runs a popular science youtube channel. While Hossenfelder is a qualified theoretical physicist and generates well sourced videos, the need to present information in a snappy and entertaining way at times leads to contrarian responses, for example in her video Hydrogen won't save us which does not take on board relevant technical innovations for generating hydrogen from sea water which were available at the time of publication of the video. I would therefore rank her 2,5 on the proposed scale.
Can you summarize the video Hydrogen won't save?
This video explains why hydrogen fuel cells are not the solution to the climate crisis. It is argued that hydrogen fuel cells are too expensive, have a low energy density, and require large amounts of energy for production. Hydrogen production also causes significant emissions, and it is difficult to store and transport. The video concludes that, while hydrogen fuel cells may have some limited applications, they are not a viable solution to the climate crisis.
