There 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.

The... thermodynamics? Surely you're joking?

For supply chains see particularly http://en.wikipedia.org/wiki/Simon-Ehrlich_wager

Interesting 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.

Not sure how well that's supported by the empirical evidence there buddy.

I agree, copper appears to be a major problem coming forward.
