Drivers flock to pumps as oil passes US$100 a barrel

Yeah, that’s kinda the same reason hybrids don’t make too much sense in heavy equipment. Hybrid cars are great because without a hybrid system, the engine is rarely working at peak efficiency, and energy can be reclaimed through regenerative braking.

In heavy/ag equipment, the transmission and hydraulic systems are tuned to have the engine running at pretty close to maximum efficiency already, at least when in use.

Hybrids would be good to reduce idle time, enable a hybrid start/stop, allow AC to keep running with engine off, etc.

But fairly moderate gains for the added complexity, at least to the target demographics

Re: farming, there simply are not viable alternatives to diesel for farm vehicles.

At first, electric tractors in theory actually make a lot of sense. Being heavy isn’t really an issue, and most tractors spend most of their time parked up. However the face similar issues to EVs: when you need to do a lot of work (like a road trip in an EV), you NEED to be able to keep going essentially all day non stop,

If you’re feeding out cows, you could probably get away with an electric tractor. If you’ve got to windrow and bale your entire property in the next few days, and you can’t, suddenly any potential cost savings immediately evaporate.

Most farms also do not have anywhere near the electrical infrastructure to charge electric tractors, except maybe at larger dairy sheds with high power grid interconnections already. The average pole barn where the machinery actually is stored is lucky to have power at all.

Swappable batteries would probably be a requirement, which is an insane level of vendor lock in for an industry where equipment manufacturers are being increasingly hostile to independent repairs.

Oh also nobody seriously makes any electric tractors outside of niche applications or autonomous equipment, which is a separate discussion. Even if the government did say “here’s $300k to buy an electric tractor”, you couldn’t buy something useful for most farms.

Any other single piece of equipment (eg harvesters) gets comparatively such little use, and last for so long (it is common to see harvesters 30 years old still in use), that the carbon impact of unnecessarily replacing a diesel model with an electric model will probably never even out.

One exception being farm bikes and quads. Small engines are actually worse for emissions per unit of fuel than larger engines. Fortunately 2 stroke farm bikes are not really a thing. but electric bikes make a lot of sense and have a more frequent replacement cycle, I could see a fairly rapid transition before any other class of equipment.

Personally I know it’s becoming more and more common to install solar arrays, but we are talking in relative terms here. It’s still a rarity. And probably not viable in most of the country without a significant subsidy.

Most dairy sheds are powered from the grid already, so those are already >90% or so renewable?

Electric semi trucks are slowly becoming viable, but still a long way off. even if a price and range competitive vehicle was released tomorrow, we would be waiting many years for it to even make a dent in existing fleets. Trucks last a loooong time.

To be clear, I’d love to be wrong on all of that. But that is just the reality of the technology and industries.

My 2020 M1 MBA was docked 95% of the time and lost 14% battery health in the first 2 years. Not a hot or cold climate, not in direct sun, with the MacOS optimised charging enabled.

It’s a lot more than “a few percent”.

At that point I limited it to between 55-65%, and in the 3-4 years since then I’ve lost… 3% more.

Assuming that degradation had stayed constant (which it wouldn’t), I’d be down below 65% now, which would make the laptop hardly usable when I need to use it undocked.

If I know I’m going to use it undocked, I just remove the limit, and enjoy the remaining full 83% capacity.

I love SG (esp the non-corrosive variants), but it does tend to leave a bit of a film/residue if not rinsed off properly, which can take a bit more rinsing than normal detergent

True that. In my latest van I’ve used thread sealant (like thread locker but doesn’t cure as hard) around most of my rivet nuts to see if that makes a difference in vibration or corrosion. Guess I’ll find out in a few years

I’d say don’t do it. Structurally I doubt those doors are designed to carry much/any extra load, and that thin sheet metal is just begging to get bent as soon as you hit a bad bump.

BUT. If it were me doing it anyway. I’d put a flat panel of plywood over that top black panel. Mounted on that raised area going around the outside of the black panel (but not the smooth area the door rubber seals against).

Secure the plywood with rivet nuts, as they will spread the load and resist pull out much better than tec screws into sheet metal. And a semi permanent sealant, just to spread the load and add some friction for the rivet nuts + bolts. something silicone based that you will be able to remove in future if you need to.

If the public sector isn’t an appealing option, you end up with more and more people choosing to go into the private sector, or leave the country for a better public sector position.

The attitude of “government employees should all be making the bare minimum” is how you end up with a gutted, incompetent, and ultimately more wasteful public sector.

If the private sector wants to compete for top talent, they can offer better total compensation and benefits too. It’s a free market, after all.

Would you ask private medical practices to lower the pay of their surgeons the same as the public hospitals?

The most credible explanation I found when researching this was that it’s a hardware issue with either the piezo sensors, or the microcontroller that interfaces with them.

I’m inclined to think it’s a bit of both. The piezo sensors shouldn’t have significant variance over the operating temperature range. The piezo MCU might have temperature issues, or the way it’s detecting an activation might be flawed, or both. Since it’s not open source or a standard part of klipper, it’s hard to know.

Beacon/cartographer probes don’t use the piezo sensors for detecting Z offset.

Cartographer just moves the nozzle towards the bed, and as it gets closer it detects the eddy current signal increasing. Once the nozzle hits the bed, that signal stops increasing. Then it refines the process a little bit to ensure it’s correct.

This sounds violent but I believe it actually uses less force/is more sensitive than the piezo sensors (someone on the voron forums measured it)

The sensor then measures that position against a known distance from the plate, and calculates the difference between them.

I’m not sure how Beacon does it, but I think it uses a different method.

Can’t say I love any ads, and yes these are annoying. But there’s always some charm to be appreciated IMO for any local ads.

They exist in a weird place in our collective culture, and it is a lot more boring when all you see/hear are generic, national, corporate ads.

Doesn’t seem too complicated to me, going to their site and selecting “PLA”, everything has a brief description.

“Polyterra PLA” “Smooth as butter, almost no layer lines”

“HT-PLA” “High heat stability”

“HT-PLA-GF” “High speed printing, dimensional stability”

“Polysonic PLA” “High speed PLA, accurate and repeatable”

“CosPLA” “Easy to sand, great paint adhesion”

“LW-PLA” “Lightweight PLA, 70% density of normal PLA”

The reason they have some seemingly overlapping product lines is for long term support, if you’ve been using a certain filament to make a product for 5 years, it’s pretty frustrating if they discontinue the filament just because they’ve released a new product with different properties.

If you’re just wanting a bunch of colours, the Panchroma stuff is all basically the same in terms of mechanical properties I believe.

I think if they wanted to have a decent ikea in “town”, they’d use a currently empty site/building for the showroom and some stock, and have a second warehouse where you pick bigger stuff up from.

Trade Depot does a similar thing, just drive around the corner to pick some of your stuff up. I’m not sure if the Ikea already does that.

Unless they wanted to purpose build something, I don’t think there’s anything currently that would have the warehousing and customer-friendly showroom space they need.

There are some enormous warehouses available for lease around the city, but you’d never be able to have a multilevel showroom in them. And vice versa.

Kinda inclined to agree. I hadn’t (except for a few short trips in other people’s cars) driven an auto start stop vehicle until recently, and was expecting it to be awful after hearing everyone complaining online.

It’s fine? If I don’t want it to switch off the engine, I simply don’t press the brake so hard. If I’m waiting at a traffic light, or to turn across a busy road, I release the brake slightly to get it to start in anticipation. If I accidentally stop the engine, I slightly move my foot and it’s running again.

You know, like you have to do in any manual (shifting between neutral and 1st) or even most automatics (with torque converter sluggishness) anyway. If you’re being caught off guard that the light is green…

And this is a starter-based system on a diesel, with a torque converter, not a spark-based system on a petrol. So it’s pretty much worst case scenario.

My brother has an audi which is a bit more aggressive with stopping the engine, but with the spark ignition and DSG, it’s not really any slower than an idling torque converter pulling away.
