Came across this:
https://arstechnica.com/cars/2018/03/can-you-build-an-environmentally-friendly-megatunnel-sweden-thinks-so/
The article is in English.
The video is in Swedish, but even without understanding a word, I'd imagine they're saying, "We are Swedish, we invented Wurm, and we build badass tunnels." Paraphrasing of course.
