About
Two Dutch electrical engineers mapping Elon Musk’s companies as an engineering stack — plus a road trip in October 2026.
Harry de Groot (The Hague) and Bernard de Groot (Deventer) both studied at TU Delft and have worked in the United States. This site is technology and analysis, not politics. It is not affiliated with Musk or his companies.
Scope: factories, labs, launch sites, and the nine-domain roadmaps. Not stores, Superchargers, or every Starlink gateway. Sources are public (Wikipedia, Electrek, SEC filings, KeepTrack). Unknown figures are marked “—” or “~”.
The October trip is field notes and route audio on Journal (The Second Coming plus five rabbit holes). Insights are essays plus four Musk episodes.
