As an engineer, I do NOT believe EVs can ever be viable. The thermodynamics doesn't work. The supply chains do not work for either energy or manufacturing.
I will never buy an EV because of the engineering analysis of this.

- TheLoafOfBread 4y agoI agree, copper appears to be a major problem coming forward.
- scythe 4y agoThe... thermodynamics? Surely you're joking? For supply chains see particularly http://en.wikipedia.org/wiki/Simon-Ehrlich_wager http://en.wikipedia.org/wiki/Simon-Ehrlich_wager
- WalterBright 4y agoThere was a popular HN article a few days ago that claimed EVs had a drivetrain with 100% efficiency. My replies showing that was absurd were not well received :-) The article turned out to be written by a ski instructor. I emailed her with the math errors in her article, but received no reply. My conclusion is there's a lot of wishful thinking around EVs, although I agree that eventually EVs will be most of the market.
- sib 4y agoInteresting that the two in my garage seem quite real and manage to transport us quite effectively. My brother-in-law with the PhD in physics hasn't yet proven anything wrong with the thermodynamics. 10.0 for viability.
