Are you in the car industry? i feel no one talks about refresh cycles so confidently unless you’re very tight.
I think 99.9% of people in the industry have no interest in shaking the equation that feeds. but,conversely, there really is nothing but upside for the consumer. cars have been “refreshing” for decades in a fashion that is not driven by function. I think ‘visually or recognizably new’ is a marketing cheat that wastes resources.
I think some believe the truck is ugly to draw attention but, and while i can’t rule that out, i think the weighting would be in the 10% realm. the remaining , at least originally,based on pushing the envelope as practically as possible. for instance, to be able to fold the metal of the car to simplify it’s construction.
Stainless steel holds a special place in many engineers’ minds. this truck is fundamentally cool because so many ideas got to come together under one hood. a truck is foremost a tool, like a hammer, and nobody tries to keep a top coat nanocermajama on their hamma!hehe
Lots of cynics here can’t separate the baby from the bathwater. You may need to get off your device and try driving one. Moreover, it’s an EV and i know reducing carbon emissions is a value that’s widely held here. It might be that you can’t have your cake and eat it too.
It just feels folks here want to align the people with the things with the beliefs and then let the negative opinion span across all of it as if it were one thing. It feels intellectually lazy. Or is it stereotyping?
i wonder if these detracting comments are meant to be persuasive or just score points with like the like-minded. Consensus indicates something, i suppose, lol.
I think it’s okay if people take responsibility for their actions, to take risks known or unknown. It’s okay to live in a world where we’re not entirely insulated from negative consequences. Ive always been bummed by how inaccessible chemistry is.
Most diyers are using LFP at this point and that’s considered quite stable. a smaller group try to reuse old ev batteries and those are generally considered more risky because of the runaway effect that’s possible- which still seems relatively low. regardless, more stable chemistries are always welcome and i agree with others that the discharge recharge and cycles would be amazing!
I don’t think it can be assumed. if the rain increased vegetation, i wouldn’t rule out an increased water cycle and greater amount of water in the area in general. Honestly, i wouldn’t be surprised if it benefited neighbors. I’m no expert and there are countless variables, maybe a high percentage of the rain used then sent right into the ground as waste water- never to have the chance to evaporate. or never taken up by vegetation at all. Time reveals all, despite whether this was a hasty experiment.
This is so peculiar. If the body plans to die then maybe you can interfere with it. eeveryone just assumes the body would live forever if it could but that would t agree with the value of sexual production.
Ben_bai said it pretty well. water is good but it can cause rust, pressure, freeze, leak, etc. sand avoids most of this. the big thing is that sand can be heated much much hotter and this helps make up for its shortcomings relative to water. they likely charge and discharge with air blowing thru stainless steel network of pipes thru the sand. this would require special tuning. as someone else mentioned, the thing with water is that the temp is uniform everywhere because water transfers heat within its volume easily. sand doesn’t, so you need pipes spaced out right.
i’ve wondered about insulation but, i think you can step it out with refractory bricks first then a mineral insulation, then something like perlite or fiberglass. the hot air would interface with heat exchanger to transfer the heat to whichever fluid that would go on to heat the home/s. since the sand can be heated to 1700F or more, a kiln or quartz heating element that can exceed this temp is needed. last, a thermally isolated heat temp tolerance fan would be required. i guess a slew of sensors in the sand and at the exchanger unit and output, i can imagine wanting sensors everywhere for tuning sake.
This is great technology, simple and effective. I’ve spent many hours reverse engineering to see how effective and expensive it might be. I’ve found it’s very cost effective but heat can be hard to calculate. i like that they did a prototype. i think i’ll do one at some point. for an individual house it makes more sense to improve my insulation but i think ill still build a small version for fun.
This is a rather one sided discussion here. Aside from the fsd hysteria, the camera set and current functionality for automatic breaking may significantly reduce front impact to pedestrians. I also feel it is disingenuous for no one to mention how dramatically lower the front “grill” is compared to other trucks and many cars. the sharp angle is a concern(see, give evidence of a balanced view). overall, the low and regularly sloped hood is probably a better situation than many here are guessing. unless your boots are stuck in the mud, people carry the majority of their weight above the bumper of the cybertruck- this really changes the dynamics, suddenly you’re sliding up a perfectly smooth slope. obviously still some questions about how the steel will respond and hardness is a concern still. but perhaps the equation changing doesn’t mean it its for the worse, many parts and pieces come together in something fairly novel here.
it is fun to watch the technology grow and morph- especially on the same daily route.
it’s also nice to have as an alternative to a knee when you need to do something awkward, like reach back or sneeze. there is always the heart attack scenario but overall i definitely trust it to drive for a short stint and to know it’s there to grab the wheel if i get in a bind.
on the highway it is excellent and really takes micro stresses out of a long drive. lane keeping is maybe 90% of it so i would weight this pretty low as a differentiator from other automaker offerings. still, i never had it on the car i came from- so it’s hard to sift that out of my impression.
these things are not intractable but nobody has made a comment that fully captures the complexity. some in building science talk about smaller diameter pipes but code opposes it. There is so much to discuss. i’m tempted to launch into all of it but i think one interesting thing is the focus on hvac in the wake of the pandemic but not hot water as much. when the protocol for hot water hand washing is like 2 min or something but who omwould do that when that equates to 4 minutes total for waiting and washing. hot water is usually a joke and not nearly enough is being done for the basic code- all we have are schemes for select few.
No one mentioned rolling resistance when increasing weight- i can’t say offhand where that loss becomes significant or not but i believe it’s worth consideration.
also, the energy doesn’t need to supplant the diesel engine but it could assist it.
the real math is “can it carry its self, and more” and if so, “can it’s assistance save the fleet money over the life of its service”. i have my doubts but it doesn’t sound like anyone here or there wants to show any math…
I live in the twin cities and have routinely made it to Duluth with 50% left (153mi)in the MY LR. The thing that’s not mentioned that has a dramatic effect is air resistance-the difference between 65mph and 75mph is startlingly and not shown in this data. I’ve also gone from duluth out to the middle of red lake in -20 F flying around 80. let me tell you, that was extremely poor efficiency!
the full picture never seems as news worthy as cherry picking sensational data. is narrow analysis intentional? i always wonder.
One trick gardeners use is to just bury the tag, often the one that came from the store. maybe a eighth of an inch or just under some wood mulch- keeps it from uv and let’s you check if you’re desperate.
You could have a method for locating like 4 inches from the plant stalk to the north.
the plaid, i believe, is sub 2s. it is a vanguard product. i believe they use the same motor in the semi- so, in hindsight, they started with impractical fun but had an eye on practical power down the way. This is rather smart, no?
I think the appearance is largely defined by its aerodynamics. people may be calling for them to make arbitrary changes in appearance but i’d rather they keep the functional shape.
It’s probably like mutual funds vs stock picking. some parents will do better and some will do worse. the child gains the interest money- if the parent is a bad stock then it’s bad in isolation…
schools are predictably mediocre but public/visible.
if the parent’s decision is driven by their own schooling experience and/or desire to change an aspect of society then i think it’s questionable to make the child an instrument of that.
somehow this answer reminded me of the good advice for starting to tighten a nut. first turn left till you feel the nut drop- then turn right. I feel there is a universal lesson here. Maybe going, as the crow flies, directly toward your goal isn’t always best.
How would this happen? can you give an example? are you saying the climate is getting closer or passing through our body temperature range and so they want to jump in to our regulated bodies?
The owner of nootropics depot has convinced me that, apart from theirs, maybe only 1% of the products in the supplements industry are what they say they are and/or remotely close the stated dose.
Aside from that, the website looks great!
It’s more common in roofs than walls. but is becoming more common on both. As people continue to take house performance more seriously, more aspects are being addressed. unsurprisingly, foil reflects radiant heat gain when you’re trying to cool. maybe directly from the sun and that emitted from hot siding.
I have autopilot, fsd and now fsd beta. i’ve read all the comments up till now. most of the opinions seem to come from a good place but not experience. before i say “ ask me anything” let me start out by saying, within 20 seconds of activating any of these features, you need to shake the wheel to prove you’re there. there are plenty of clues before that that indicate this is not a hands off affair, but this alone is where you know it’s not going to be a ‘set it and forget it’ . ok, ask me anything.
i dream for it as well. but, again, “united” is only incidental, right?? of course, it’s not coincidental that people,individually, jumped on the great utility that fossil fuels provided. now we are looking for people to see the benefit to prevent something fairly unintuitive and intangible- it’s a big ask. there’s room for plenty of approaches but i would root for the ones that dances around “greater good” but, rather, work within the framework of human behavior for what it is. altruism is in the mix but probably can’t be relied upon to be the primary driver for where we need to get.
This comment is a bit pithy for the reasons already mentioned and more. Humanity has never acted as one thing. There is no order to the activities required to turn things around for the world. Reintroducing a keystone species can draw more attention to an under appreciated ecosystem a la polar bear. conversely, it could make light of saving a species if we can simply reanimate it down the road. But again, there is room for all sorts of efforts. i doubt more tools and more species would be an overall detriment. i would love to see an ecosystem rev to full glory.
I’m surprised there has been only 1 or 2 comments on HRV ERV. There are many products available to help exchange indoor air with outdoor air while conserving heat and or humidity. here is a smaller solution that is somewhat expandable. LUNOS e². I was hoping i’d get some more ideas from this discussion.
