I’d be curious to see your numbers. Based on my electrical costs of about $0.35/kwh and 87 gas holding steady below $5 for nearly a year, 1000 miles driven in my real-world 45 mpg Camry hybrid costs about $110 while the same in Tesla Model Y costs about $95. Tesla however is $10k to $15k more.

The only maintenance my Camry will need for the next decade or so that does not exist in Tesla is regular fluid changes which amortize to about $200 per year

Ps in SF Bay Area and don’t qualify for tax incentives

> Based on my electrical costs of about $0.35/kwh

Definitely it's massively less compelling in areas with extremely high electricity costs. That's pretty much as expensive as electricity gets in North America, isn't it? I think it's significantly more compelling basically anywhere else. E.g. in Ontario where I live, if you're set up appropriately and charge between 11pm and 7am it's $0.028/kWh (CAD), i.e. less than 3 cents per kWh, or roughly 1/35th the price you're paying.

If I've done my math right, that's works out to be less than 2$ USD per 1000km? A difference of 108$/1000km is 1728$/year for the statistically average-driving Ontarian. Adds up pretty fast!

That's a lot of stereotyping. Has it occurred to you that not every Android user wastes time to "tinker" with their phone and they're just normal people who use it like you do your iPhone?

Android is not like Linux were it's exclusive to developers, geeks and tinkerers. The market share also exemplifies that it's just as much for average joes as iOS.

I have a hard time with threads like this because it feels like half the comments are straight out of an Apple ad. "It's simple", "It just works", "PC is some nerd twiddling bits but Mac is cool and gets things done". It feels like a cheap shot, but when "the nerds" are proclaiming Apple the one true OS the hacker ethic is really suffering.

My wife switched from Android to Apple, then Apple back to Android a couple times. Turns out they're really not that different, and the "simple" one is the one you're used to (noting in the Android ecosystem companies like Samsung really do a disservice by trying to stand out from stock in a different-but-no-better way).

As far as I can tell there are no hr monitors that can connect to chest straps. If one did then instant purchase. But I like the other tracking and sync of Apple Watch too, that would be a bonus.

I have a Garmin Fenix 6 that definitely can do this, I do it all the time. You can customize the display so that it only displays the heart rate, or e.g. the heart rate and heart rate zones. While the Fenix 6 is expensive, I think there are a whole bunch of watches in that segment at different price points that will do what you want.

I think the general category you're looking for is devices that support ANT+.

I think this is too loaded and subjective to form a useful conversation around. Maybe you can expand and get more specific answers? For example,

> Android phones still feel like cheap plastic to me

I personally think "cheap plastic" is often the dramatically superior choice for phones from a functional perspective. It typically implies easy and low cost to replace, as well as lightweight and durable. Permeability to radio signals is also a solid bonus. There are definitely tons of plastics that are not cheap feeling, unless one is of the mindset that plastic = bad in this context.

I cannot consistently qualify for majors, I have never been paid to run, and I’ve never entered a race that I had the intention of winning, and I have a normal job and social life. Perhaps you could qualify it by saying I’m a casual _endurance_ runner. But I am very much a casual. My lifestyle might be vastly different from a sedentary lifestyle, but it’s not so different from that of all the other casual marathon runners out there.
abstract_put · 3 years ago
Yeah, I get that. I think just a terminology thing. It seems like you're using "casual" to describe your mindset whereas I'm understanding "casual" to be offhand, or without significant investment. Forgetting about the absolutely massive time investment, spending > 2000$/year on running shoes alone is a distinctly not-casual thing to do.

> it’s not so different from that of all the other casual marathon runners out there

Maybe this is the disconnect? People who have ever run a marathon at all are < 1%, and people who continually run marathons casually are a niche within that niche. If the audience is "people who run more than 50km per week" then I think "casual" probably gets the right idea across, that's just a teeny tiny audience.

I typically get around 400-600 kms out of a fresh pair of running shoes before the tread is completely gone and the energy return structure stops returning energy. I typically run about 100km/week. A bit less if I’m tapering, or injured (not very often), or on holiday. I also walk a lot, which I have different shoes for, but that adds an extra few pairs to the annual shoes bill as well.

Edit: I probably go through shoes slightly faster than most runners, because I weigh a bit more than most runners. But I don’t think that’s a huge factor.

> I’m more-or-less a casual runner

> I typically run about 100km/week

This feels pretty naive or disingenuous. I'm pretty sure vanishingly few people understand 100km/week to be "casual". While you may not feel like you're a "pro" or have a competitive mindset, I'd argue averaging more than an hour a day at pretty much literally anything moves you out of "casual".

I'm just waiting for a "green building" code to specify "all windows shall open."

Imagine the panic that would cause in the construction industry.

abstract_put · 4 years ago
I think generally "green building" (at least the mainstream stuff) focuses on insulation + air tightness, and then mechanical ventilation. In that context, operable windows would be mostly be a "just in case of overheating" or similar, and the expectation would be CO2 et al would be managed by the ventilation.
abstract_put commented on Heat pumps are efficient and eco-friendly. So why are they so rarely used?   washingtonpost.com/techno... · Posted by u/woldemariam
dublin · 4 years ago
My parent tried heat pumps twice. They are incapable of even handling the usually not-very-severe winters of central Texas without resorting to turning on their pathetically weak resistance heaters, an those can cost nearly $100/day to run! Their second Gen system was much newer and more expensive, but not much better.

The definitely are not capable of handling any subfreezing temperatures. Natural gas is, overall, FAR more efficient for heating when the supposed efficiency of the heat pump gets slammed by the inefficiency of electric heat.

So that answers the OP's question of why we don't use them: They're fiddly, expensive to buy, and both don't work in, and are insanely expensive to operate in the cold.

abstract_put · 4 years ago
Is it possible your parent's house is not well insulated/sealed? Potentially _really_ uninsulated? I've talked to people here (45 degrees latitude) who are happily using their heat pumps and we're looking at models for ourselves. One caveat being the people I'm talking to live in above average performance homes (in terms of insulation and air sealing).

You know what else would make cooling your home energy efficient? If your home was not absorbing as much heat from the sun. Most roofs are black petroleum product, because oil everything! For not a whole lot of money, the cost of some digging, running pipes, and a pump, one could encase their home inside a closed loop 5mm tall waterfall during summer, which would drop their energy bill significantly. The idea is a little water runs over all outside surfaces of your home, taking whatever heat the surface of the home has with it (but also taking heat through evaporation) back down under the ground surface where it exchanges the heat. Add water as it is lost through evaporation. Really, if civil engineers and builders had made everything a water wonderland instead of heat absorbing black top, it would be a lot fn cooler.

Is this an actual construction technique in real life (beyond DIY-ers)? Is there a name for it?
