  • No disputes from me on your assessment. In principle I’m a big fan of EVs as a maturing technology and my only hangup with Tesla is its association with the person who is its CEO and the role he’s chosen to play in US politics.

    I’ll gladly champion a vehicle that has incredible efficiency in converting its stored energy into mechanical work, especially when that stored energy came from a source that’s 40-60% thermally efficient (for combustion-based processes) or derived from solar/wind/geothermal/hydro sources and can be partially recuperated via braking. It’s too bad there aren’t more EV options for people who want or need a 3/4 or 1-ton pickup (of which I happen to be a big fan for hauling/towing/plowing).

    The one area where I’m still dubious of electric vehicles is in cold climates, although I think I’ve read heat pumps are being used with success. Otherwise, I’d propose a small auxiliary tank (preferably propane, if infrastructure permits) and a “Chinese diesel heater”-type unit be installed simply for cabin heating/defogging. Few energy conversions make me cringe more than that of high-exergy electricity (derived from non-renewables) directly into thermal energy, convenient as it may be for the end user.

    Of course, it’d be nice if that combustive heat could be generated from sustainably-harvested hydrogen instead of an extracted hydrocarbon, but at that point, a fuel cell running a heat pump would be even better, with resistive waste heat from the FC an added bonus. But now it all feels a bit Rube Goldbergian…

    Anyway, what’s your take on EV use in climates with harsh winters (such as Canada/Alaska/Montana/Wyoming/Minnesota), especially when long range might be needed?
