Showerthoughts

A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The most popular seem to be lighthearted clever little truths, hidden in daily life.
Here are some examples to inspire your own showerthoughts:
- Both “200” and “160” are 2 minutes in microwave math
- When you’re a kid, you don’t realize you’re also watching your mom and dad grow up.
- More dreams have been destroyed by alarm clocks than anything else
Rules
- All posts must be showerthoughts
- The entire showerthought must be in the title
- No politics
- If your topic is in a grey area, please phrase it to emphasize the fascinating aspects, not the dramatic aspects. You can do this by avoiding overly politicized terms such as "capitalism" and "communism". If you must make comparisons, you can say something is different without saying something is better/worse.
- A good place for politics is c/politicaldiscussion
- Posts must be original/unique
- Adhere to Lemmy's Code of Conduct and the TOS
If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.
Whats it like to be a mod? Reports just show up as messages in your Lemmy inbox, and if a different mod has already addressed the report, the message goes away and you never worry about it.

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?
My partner and I backcountry ski, iceclimb etc. One of the reasons we went with the Ioniq 5 was that we can sleep in the back and use the heat pump to keep us warm.
We recently did a weeklong ski trip with it. We drove from from Golden, BC back to Calgary, AB (250km/150mi) in -16C (3F) and used 70% of a charge. One day on that trip, we were backcountry skiing in similar weather and the car sat outside in that weather for 8 hours. No loss of battery.
One of the unexpected features I really enjoy is that I never pump gas in the cold any more. I programmed my work schedule and the car pre-warms for my commute. I get home, plug the car in, and it's always ready to go.
Thanks for the great beta! When it finally comes time for me to retire the ol' 14 y/o flat-4, I'll keep your advice in mind.
