Well that's depressing, if hardly surprising: hurricanes can pick up microplastics from the ocean surface (probably via seaspray from the violent ocean surface, and possibly also some from bubble bursting) and dump them back on land:

FullOnElectric,

@mackaj @helenczerski “Microplastics haven’t just gone airborne, but have become a fundamental component of Earth’s atmosphere.”

Always buy the more expensive wool sweater, or cotton clothing that you wear until it wears out because you love them so much. And paper bags for the odd time you really need them.

A friend made us a cotton bag lined with a thin coat of beeswax to keep bread in. Much better than hermetically sealed plastic bags.

There are solutions.

So the cybertrucks apparently have a neat design feature where all the electrical systems are run through a single cable. As opposed to the more common way of doing things which is to have all the lights, displays, windows, etc have their OWN cables. Muskrats are touting this as a design innovation since it cuts down on the car's complexity and saves on copper.
Why is this important?
Because the cybertrucks have a massive built-in single of point of failure. In a normal car, your windows shorting out or your display short-circuiting means your windows don't work or your display doesn't work. But the cybertruck runs ALL the electrical systems through the same cable. One shorts out, everything shorts out. EVERYTHING. Doors, windows, power steering, the works. That cable gets damaged, and nothing will function.
Sure, in engineering, you want to keep things simple if possible to cut down on maintenance and make things easier to fix... but sometimes you NEED that complexity.

OP is bragging otherwise.

FullOnElectric,

@mikemathia CAN bus (component signalling and control) has been used since the 1990’s. Nothing new there. What is new is setting the low voltage system to 48V vs 12. That’s what saves copper, and the trade off is that you cant tap into virtually every other automotive component built for 12V.

But 48V is the clear path to save on wiring cost. With higher insulation values required the risk of a short is negligible without acute mechanical intervention.

FullOnElectric, to Electricvehicles

Practical, low cost solutions always the best in the long run. North America needs to leave the supersized automobile behind.

The world will eventually run out of fossil fuels, so our choice is really between stopping their use on our own terms now or being forced to find alternatives in the future while having a terrible climate, tens of millions of deaths from air pollution and climate disasters, higher sea level, etc.

FullOnElectric,

@petergleick
Exactly. The problem is we've just released a 100 million years or so of the earth's stored carbon in just 100 years. There's still a billion or two left in the ground.

Fortunately electrification makes everything 4x as efficient, and there is an unlimited supply of free renewable energy. Sure, it's an infrastructure change, but how hard was it to go from landlines to smart phones?

If You’ve Got a New Car, It’s a Data Privacy Nightmare
"Bad news: your car is a spy. If your vehicle was made in the last few years, you’re probably driving around in a data-harvesting machine that may collect personal information as sensitive as your race, weight, and sexual activity. Volkswagen’s cars reportedly know if you’re fastening your seatbelt and how hard you hit the brakes.
That’s according to new findings from Mozilla’s *Privacy Not Included project. The found that every major car brand fails to adhere to the most basic privacy and security standards in new internet-connected models, and all 25 of the brands Mozilla examined flunked the organization’s test. found brands including , , , , and collect about drivers including race, facial expressions, weight, health information, and where you drive. Some of the cars tested collected data you wouldn’t expect your car to know about, including details about sexual activity, race, and immigration status, according to Mozilla."

FullOnElectric,

@autonomysolidarity has anyone pulled together on how to disarm these techniques and devices? It appears that mozilla simply did a legal review of policies. That’s the easy part.

    I saw so many people with folding phones today that it has given me total tech envy.

    My OnePlus 5T is approaching 6 years old. Has a replacement battery and flashed with Lineage in order to get modern features.

    I'm fully aboard the Reduce, Reuse, Recycle train. So I'll wait until it gives up the ghost and then buy a 2nd hand fold.

    Looks like only the Pixel has 3rd party ROMs. So that's another good excuse to wait.

    But I want a new toy!

    FullOnElectric,

    @nwp @Edent
    After 6 years, my Blackberry Key2 is finally nearing an end. Prolonged camera use causes overheating shut down and lack of updates past Android 8.nnnn is now affecting some functionality.

    With today’s state of @pluralistic “enshitification” I’m happy to have fewer apps and stay out of tech databases everywhere.

    So what’s the masto equivalent phone hardware to purchase today? Do we have to be beholden to perpetual planned obsolescence?

    FullOnElectric,

    @nebula @Rodeo

    Here’s how to compare baseboards to heat pumps.

    Baseboards create heat through resistive loads. As all the energy creates heat, you can say they are 100% efficient, but that is misleading if you take that to be good.

    Heat pumps simply move heat, in either direction, to heat, or cool, and they do this using 1/3rd the energy.

    Today’s heat pumps work at much lower air temperatures, can also use ground loops, or exchange heat from water bodies.

    FullOnElectric,

    @Lockpro @ajsadauskas @technology oh, it isn’t unique, but X.com has been in Elon’s head since 1993 when he worked for the Bank of Nova Scotia for a summer job assistant to the VP Strategic planning. It was’nt BNS’s plan, but Elon’s to put every banking function online. A few years later was operating in SiValley, but Elon’s Board lost confidence in his grand design, and removed him as CEO. ../2

    FullOnElectric,

    @Lockpro @ajsadauskas @technology

    Instead they focussed on payments only, which was the plan of a failing startup that merged with X.com a few months earlier - it was operating down the hall from X.coms small 2nd floor office. The name of that startup ended up replacing X.com’s — PayPal.

    In 2003 PayPal was sold to EBay and Elon’s share of the sold company funded his investment in two new startups, Tesla, and SpaceX. His share after tax was USD $300M.

    mzedp, to Hydrogen Spanish

    Hydrogen bus project cancelled in France once it was realized that they could accomplish the same for 1/6th the cost using Electric buses.

    I mean... it's just common sense. We already have an electrical grid, not a hydrogen distribution network.

    Plus, Converting energy to electricity to battery potential to motion is WAAAY more efficient than converting energy to hydrogen and then converting it back.

    FullOnElectric,

    @Hypx I studied business opportunities in vehicles (MHD) a couple of years ago, based on the weight savings of H2 systems over battery weight for large trucks and buses. H2 has some advantages, especially in cold climates, because of heat cogen.

    However the conclusion was that the cost of H2, efficiently diastributed (straight from production plant) was about the equivalent cost of diesel fuels.

    ... 2

    FullOnElectric,

    @FullOnElectric Maintenance of H2FC and lifespans of pressurized vessels all contribute to higher cost. Energy efficiency doesnt matter as long as there is no carbon impact - its just cost.

    The gains would be from the more revenue payload per trip v battery weight. (Think cement trucks).
    ...3

    FullOnElectric,

    @FullOnElectric

    However -- recent developments in battery energy densities, doubling or tripling, will end the cost benefits of H2FC.

    Will these new chemistries be here before hydrogen takes off? If they do, H2FC will be dead in the water, except for cogen applications.

    Hydrogen storage and distribution just too costly.

    FullOnElectric,

    @Hypx target densities of 500Whr/KG already claimed by CATL. Other solid electrolyte companies are targeting 1,000. Sure they are not TRL9, but the yearly increase of energy densities is about 5% and we’re nowhere near market maturity. These are technologies on the move.

    The problem with hydrogen is storage and distribution. If you know of how this will be fixed do tell!

    FullOnElectric,

    @Hypx if you want to talk fuel cells, they do have severe efficiency limitations. They become more inefficient the closer you get to maximum output - about 30% less efficient at 100% output than at 50%

    Steady state is the best way to run fuel cells, which means having larger battery packs on board so that the fc does not have to respond to the variable load requirements of vehicles. As i said earlier, the best case is when you also need heat, such as cold climate operations.

    FullOnElectric,

    @Hypx of course, at 700 bar. About 10x the operating cost of BEV.

    FullOnElectric,

    @Hypx you dont know what you are talking about. It was never about torque. If it was, electrics would have won out.

    It was the fact that lead acid batteries were not advanced enough, and the fact that in 1912 the cost of electricity was about 33 cents/kWh, and gasoline was 5 cents a gallon. Standard oil could set up a network of fuelling stations faster than utilities could build electrical grids. Electricity was only in cities back then.

    FullOnElectric,

    @Hypx i know steam cars existed. Of course they had excellent torque - that’s why their main application was as a locomotives. But as cars they took too long to warm up, and driving around streets with a pressurized boiler led to some horrific accidents.

    They couldn’t compete for a number of reasons - but the steam whistle was a fantastic announcement of your arrival or departure!

    FullOnElectric,

    @Salty @Hypx the leading use case for H2FC is large that operate against GVWR where the trade-off is more payload each trip for less battery weight. Cement & dump trucks, for instance. Shorthaul aircraft might be another application, including wherever heating is required, as that’s 50% of the output of fuel cells.

    Agreed, in LDV there is no cost effective use case. But what will come first, buildout of the vehicle supply chain, or better ?

    FullOnElectric,

    @Hypx @Salty As to when:

    … they can take rare metal catalysts out of fuel stacks? ,,, stack maintenance is zero, as are over their lifetime (measured in decades)? … hydrogen distribution and pricing is equivalent to the electricity grid? … when they can store safely at high densities at ambient temperature and pressure? … when the production of vehicles rises above 100’s per year?

    Yes, of course then.

    Used EV prices tumble as overall pre-owned market levels off

    https://www.autoblog.com/2023/07/11/used-car-price-drop-electric-tesla/

    FullOnElectric,

    @Hypx the new problem of the industry is that electric cars will last 3-5x longer than ICE, and used EVs will be in circulation for generations.

    This will mean that automakers will have constant pressure on keeping new car prices low, because, why pay for the depreciation when a used car drives like new, with the same reliability.

    The only differentiator to support new car sales and prices will be the classic appeal of the latest styling and tech.

    I had no idea that VIA was capable of nearly 150km/hr!

    FullOnElectric,

    @jfmezei @chad yes, electric, fast or high speed rail is such an expensive undertaking for governments that have interests that align with election cycles, and also flies in the face of car culture and the aviation industry embedded in NA.

    Seems to me that the dual purpose of building an East-West rail line and energy corridor at the same time would make sense. Then there’s financing and ownership, always political. Every rail line in this country is also a real estate play.
