The off topic bit was whether deck's hatred was dishonest or not. I personally think he is misguided and generalizing from some specific experience. I am not an oil company basher -- quite the opposite. Happy to have a discussion about the social and economic good that the oil and gas industry provides (and the occasions on which it falls short of its standards) compared to many alternative energy schemes.
However, I was trying to respond to the point about no loss of speed from regenerative charging rather than arguing with someone whose mind is obviously made up about why he feels the way he does.
