My understanding is this is rapidly being replaced by NFC phone tapping, at least that's what Hyundai is swapping to. Annoying though, I've really enjoyed not having to dig through pockets to open the car :(

What model vehicle stalls if it can't find the key? That seems like a severe safety problem - you mean it would brake if the battery dies on the key dongle? At least in the two Hyundai's I've owned with this type of system -

Some car brands sell vehicles that open with a button push on the door, if the key is just nearby. Standard kit now is you get an RF extender that bridges the distance from a key inside someone’s house to the car; then the car just lets you

This is that, and the exact same vibe, except: it promises to keep being that simple even after you add threads, and locks, and network calls, and disk accesses and.. With this, if you write a test for a function that makes a network call a

IMO it does not, but maybe I’m just making it wrong.. It’s notable that places like French Laundry explicitly dry their home made pasta before cooking with it, IMO the al-dente texture is way better in dried pasta than freshly made. I guess

The thing is you need the lab - if you don’t have the incubator and the air filtration systems and the autoclave and the centrifuge and the… then the cells will die or you can’t extract the viruses etc. You need the lab to do this, and for

My wife is doing her PhD in molecular neurobiology, and was amused by this - but also noted that the question is trivial and any undergrad with lab access would know how to do this. Watching her manage cell cultures it seems the difficulty

It's extremely opinionated though - and sneaky because it looks like Trello (cards-in-lanes), but it really isn't; it took a lot of frustration to realize it's more like one of the older tools where the "canban board

> EV charging is 100% new generation capacity and doesn't take any of the existing load off the power grid. All the more important to ensure this additional demand is flexible. Shaping it to match renewable production and low-usage

This is rapidly changing worldwide though: as more variable production comes online, the value of shaping demand grows. Missouri is moving to hourly rates this year IIRC. EU already is on 60-min day-ahead prices and pushing hard to get to 1

Recall your entire house is a thermal battery too! In fact, all the four major energy loads in a house - Heating/Cooling, Water heating, EV Charging, House Battery - are extremely flexible. But we're still lacking good standards f

This is true and important - but subtle and easily misunderstood as simply outsourcing emissons . There is a fundamental pollution that occurs in a coal plant: its purpose is to combine carbon and oxygen to produce heat and CO2. There is no

Nah, I think I just posted late, so this ended up below the fold and got almost no eyes on it. HN has a huge early-mover bias in the comment field

Data: EV sales up 50% YoY. Business Insider headline: “Fewer people are buying electric cars”. A useful discussion for HN might be: Why are they choosing this framing? Some discussion in Electrek about why the record growth is framed as if

Our customers use their HVAC to “pre-cool” or (more often, pre-heat) their homes when rates are low.. but you need a house with enough thermal mass and insulation that it can go 4-5 hours just “coasting”, which I guess is more common in col

This was tried in Texas though, and my understanding was the capital costs were too high to not run the units constantly. More likely the sink will be - as it already is in commercial steel projects like Hybrit - electrolysis.

I have a cabin with no grid connection. It has solar panels, batteries, and a gas generator. Last year, I used the generator one time, for four hours. So, with a half gallon of gasoline, I ran a 1000sq ft home for 365 days. We can build a g

Negative prices happen constantly? Especially if you’re trading intraday and similar faster markets. It’s partially a useful thing - large generators paying to avoid stopping - but largely it’s because peoples rooftop solar doesn’t curtail

Have you done any road tripping in an EV? my experience of the app-based charging landscape has been complete horror; apps don’t work, chargers don’t start, payments don’t through.. Just last month was a new app at McDonalds in Sweden, that

Did some DIY in the US (PEX and PVC), now live in nordics; water pipes here are copper (or PEX). Expensive, but basically just really tiny EMT conduit, so totally fine to DIY.

Do you have examples of what kind of DIY work is hard? I haven’t done a ton of work on newer cars, but at least adding wiring for a hitch on my Kona EV was just as easy as any wiring I’ve done on my old truck. Is a job like adding amps and
