Electric Propulsion's Dirty Secret: Why Lithium Can't Fly (Or Float) Profitably

tldr: There's a lot of bullshit going on right now about Lithium propulsion boats and planes, don't trust the energy return on investment or viability of its profitability...it's fundamentally a net negative energy return on investment. Elon lies through his teeth and boldly in a room full of people. Physicists Get Too Much Street Cred and Access to Venture Capital I think the physicist mindset has infected a large swath of venture capital with delusions about what's possible with lithium ion battery technology. Long Live EROI analysis, even if I'm off, I'm not off by a factor of 10-100. Physicists more than any other field of people I've encountered make claims about subjects far beyond their max competency because of the cockiness induced when they were able to complete mathematical proofs that allowed them to grok logic puzzles, digital signal processing, and physics as an entire subject with ease. They never faced the analog realities. Alas...I digress. I've of ... Read full article.
