Tsung Xu's personal blog at tsungxu.com covers hardware, economics and science. Since 2022, 10 different Hacker News readers have linked it 15 times, most often “The Clean Energy Transition, a Guide”. It is still writing: the last post was on 2026-06-14, and you can follow it by feed.
Too few sampled comments (6) to say how often HN recommends it.?
Why HN links it
Long-form essays by Tsung Xu on clean energy and materials transitions, including a clean-energy transition guide and a biomanufactured materials series. HN readers cite it as a reference and recommend reading it.
Summarised by Claude from a sample of 6 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.
Thoughts as I build Vight to make door-to-door flights as normal as driving. Starting with two-seat eVTOLs for rural property owners and flight schools anywhere.

HN discussionBatteries are not produced at a scale nearly large enough to be impactful. The world consumes 2,500 TWh of electricity per hour. And that's set to increase as less wealthy countries develop and start demanding A/C, street lights, etc. And on top of that, electricity production is only ~40% of carbon emissions (meaning, electrifying heating, transport, metallurgy, etc. will drive up electricity demand even further).…

HN discussionI don't think Space Based Solar Power is going to be economically viable, even if Starship can launch for $2M per. It's not because Charlie is wrong, it's because ground based solar and storage batteries have gotten incredibly cheap and Wright's law is going to make them even more incredibly cheap in the future. https://www.tsungxu.com/clean-energy-transition-guide/ The headline is right, though. fossil fuels are de…
