On the downvotes, I assume it&#x27;s because your point is not at all relevant to the article itself or the technology it discuesses. It could easily be copy-pasted to most any article about combustion engines. Technological improvement can be useful enough even if it doesn&#x27;t &quot;save the planet&quot;.<p>Hacker News comments are for discussion of the article content, rather than being a soapbox for your views and blogposts.
