The CEO of Toyota Research Institute, Gill Pratt, had some good (albeit self-serving) points about the benefits of hybrids and PEVs to complement EVS a few years back that I bookmarked and keep coming back to:
> Maximizing the benefit of every battery cell produced requires that we distribute them smartly.
> This means putting them into a greater number of “right sized” electrified vehicles, including HEVs and PHEVs, instead of placing them all into a fewer number of long-range BEVs, like my model X. This is particularly important because presently it is difficult to recycle the kinds of batteries used in BEVs. If we are to achieve carbon neutrality, we must pay attention to all parts of the “3R” process — Reduce, Reuse, and Recycle.
> For example, we hardly ever put gas into our RAV4 Prime PHEV, which has a battery ⅙ as large as our Model X BEV. For the same investment in batteries as our single Model X, five other RAV4 Prime customers could reduce their carbon footprint too.
I'm not sure about this, because a smaller battery pack with fewer modules needs to work much harder.
PHEV batteries are discharged at higher rate (C) while a BEV can spread the load across many more modules. EV range of PHEV is so small that the battery gets fully cycled daily, while a BEV with similar commute distances and charging can easily keep batteries at a more comfortable state of charge.
The recycling thing doesn't make sense to me. For getting raw materials back the difficulty is the same (get the cells out and grind them), and having more cells per pack should amortize labor cost better.
BEV batteries aren't recycled at scale yet, because there aren't many to recycle. They're easier to reuse for grid storage, since BEV packs already have many modules hooked up to a single BMS.
So this sounds more like Toyota is just supply constrained on batteries.
> But research is showing that social media and smartphones have made us addicted to screens from a young age. It’s taken a toll on how much time we spend together
Agree completely, but it has also lead to widely held pessimistic beliefs like
> But how do we find meaning when the climate is warming, politics is broken, and technology serves profit over people? We can’t think about thriving; we're merely surviving.
I anticipate downvotes, but I seriously suggest reading https://en.wikipedia.org/wiki/Enlightenment_Now for some perspective about long term positive trends, and insights into why we over weigh short term negative news to the detriment of our mental health.
Assuming you go down the path of allowing online anything, seems like, after doing your best with parental controls, the most effective thing is time boxing screen usage. Only so much can happen in, say, 2-3 30 minute sessions throughout the day, and the chances of a kid deciding to blow their precious minutes responding to some random person seems much lower than if bored and checking messages idly. Being nearby during a healthy sample of sessions to have a pulse on what's going on helps too - usually pretty obvious what they are doing.
But I share the frustration of the author with how unreliable the controls are. Apple screen time controls routinely stop working - especially the one that only allows access to a finite list of websites. I need to check the browser history every week or so to confirm it is still working, and do some dance where I turn off controls, reboot, then turn back on every once in a while. The reason this particular control is important to me is that, even starting with something as pure as neil.fun, ads on that site have proven to be a few clicks away from semi-pornographic sites - it's terrible! And yet, turning off all internet access is such a coarse decision that limits access to things that are generally informational / fun / good (like neil.fun, or sports facts sites).
Seems like could be a good solution to using best rated (chinese) vacuum's while mitigating privacy concerns.
I am bummed that US robovacs aren't that competitive. Rooting for Matic, though currently don't seem to be as good as Dreame / roborocks [1] (can't go under furniture, apparently take longer to clean same area, tout "vision only" as a feature while charging more - you would think having fewer sensors / no lidar would bring costs down).
Yup, been using it on an older roborock s5 for several years now. It's excellent and works flawlessly with home assistant. Cannot recommend enough. The robot running its own webserver while it cleans my apartment is still so funny to me.
Less mass will yield longer range. I know you're referring to the battery accounting for a large percentage of the weight, but a smaller vehicle will get the same range with a smaller battery, and the weight savings compound. If the vehicle weighs less, then all the components supporting that weight can weigh less as well. Unsprung mass can be reduced significantly. Acceleration, braking, handling, and top speed all improve as a result. Components will also generally cost less, reducing the price of the vehicle and making it cheaper to maintain.
Neal.fun is good clean fun - my kids love it too. Neal, if you are listening, would pay for an ad-free version (I already bought you some coffees too).
The founder of Zingerman's (famous deli and family of businesses in Ann Arbor) description of servant leadership is a bit more complete and overlaps heavily with what the author of this post is advocating for:
If there is a primitive not currently supported (say running a temporal workflow service) is it possible to define a new primitive for this? Just wondering what it looks like if/when you need something not currently supported.
You can just use the resource as you'd normally would and then use e.g. secrets to define the connection settings per environment. You would however need to provision the resource yourself for all your envs. We have a terraform plugin to help you automate it.
