    Health care works better when there's electricity around. About a

    Do you have solar cells and a Powerwall and an electric car in your

    AI Overview
    Natural sources account for roughly 40% to 45% of global methane
    emissions. The largest contributors are wetlands, where microbes
    decompose organic matter in oxygen-poor environments. Other
    significant natural sources include termites, thawing permafrost,
    oceans, wildfires, and geological seeps.

    Earth did just fine when CO2 was 5000 PPM.

    And the sun was a bit smaller.

    The last time there was massive global warming - about 56 million years
    ago - there were mass extinction events.

    https://en.wikipedia.org/wiki/Paleocene%E2%80%93Eocene_thermal_maximum

    I keep on posting this link, and it never seems to register with you.

    We need more. 700 or so would be great.

    You wouldn't like it if it happened. None of the crops that feed you -
    that have been selectively bred to do well at atmospheric CO2 levels
    around 270ppm - would like it either. There are bound to be weeds that
    would like it better, so you would probably starve pretty rapidly but
    natural variation would ensure that some species would do reasonably
    well (and adapt like fury to optimise themselves for the new conditions). >>
    Veggies and flowers are grown in greenhouses at 1000 PPM and more.

    Greenhouses supply all the water and fertiliser the plants need, kill
    off weeds and insects, and supply an expensive product.

    It's not the whole agricultural industry, just the boutique end of it.

    Crop yields have increased dramatically in the last hundred years.
    Selective breeding is fast and getting faster. Some of our favorite
    things didn't exist 30 years ago.

    Selective breeding for a new environment is tricky. You've got a find a >place for your test plots in the new environment that doesn't actually
    exist yet.

    Slow breeding species like human being wouldn't do well.

    Mammals were invented in the PaleoceneuEocene thermal maximum.

    Don't be silly. They were around and quite diverse before the dinosaurs
    got killed off 66 million years ago.

    They'd expanded into most of the dinosaur niches during the previous
    eleven million years, and diversified again after the PETM had made a
    total mess of the ecology.

    Of course the primates showed just up after the PETM, so they replaced
    whatever had been occupying our ecological niche before the PETM.

    Plants love CO2.

    But our plants are well adapted to 270 ppm of CO2 in the atmosphere.

    They are hungry for CO2 and would like more. Something around 180 is
    plant starvation.

    What a load of nonsense.

    Cold kills.

    So does heat, as Europe is demonstrating at the moment.

    The cold/heat death ratio is estimated around 10.

    For what environment?

    The euros should get more a/c, if their power grid could handle it.

    It's hard to get people to invest in air-conditioning that can handle an >unpredecented heat wave.

    It's not difficult nowadays to make a variable-frequency 1-
    PPM-distortion sine wave. The problem is measuring it.

    It would be an interesting hobby.

    Did you ever build your low-distortion oscillator? I wouldn't trust a
    Spice sim at that level.

    Sure I talk to him. We take care of one anothers houses when someone
    is on vacation. We have door keys. We swap baked goods. He stays in
    our cabin in Truckee, as do some other neighbors.

    He has a fancy digital front-door lock that stopped working a few
    weeks ago. Dead battery? Code crash? I let him into my back yard, he
    jumped the fence, climbed up to a deck, and got in the back way.

    His solar panels don't make much power in our climate at our latitude.
    And they need maintanance.

    He parked the entire array on our roof when he had his roof repaired.
    That was crazy expensive.

    We don't have many hurricanes or tornados here, but panels get ripped
    off roofs where people do.

    Electric car and solar panel purchases are mostly driven by government financial incentives here. China is the main beneficiary.

    Car makers are getting tired of losing gigabucks on electric cars.

    Ford, GM, Honda, Porsche.

    Not to mention the Jaguar suicide. Apparently a 95% drop in sales is a
    clever marketing strategy.

    Maybe electric cars are a novelty buy. Like Miatas and PT Cruisers.
    Once the fans have all bought one, the sales die, and nobody wants a
    used PT Cruiser.

    Do you have solar cells and a Powerwall and an electric car in your
    residence? Are you off the grid? Post some pix.

    I live in flat in Sydney. There's no roof that I could put solar panels on. >>
    Australia hasn't got a nation wide grid - the gap between western
    Australia and the rest of the country is too big to be worth bridging -
    but the two halves of the country have both had grids for more than
    century now. Australians who live in house with roofs mostly do have
    solar panels, and anybody who has them and has the capital to buy a home
    battery (they aren't cheap) has got one. My oncologist friend and his
    statistician wife moved house recently to a place without stairs (they
    are as old as I am) and their new house has both solar panels and a
    battery. They bought the battery.

    My electric car is going to have to wait until the little Mercedes my
    wife bought in 2011 wears out. It is still doing fine and I don't use it
    often enough to worry about the carbon dioxide it emits.

    My next-door neighbor bought the house with solar panels. He hates
    them.

    Get him to add a power wall or something similar, and his electricity
    bill will go down at lot. That makes the solar panels a lot more attractive. >>
    You probably don't talk to your neighbours about that sort of stuff. You
    don't know enough to do it well.

    <snip>

    Sure I talk to him. We take care of one anothers houses when someone
    is on vacation. We have door keys. We swap baked goods. He stays in
    our cabin in Truckee, as do some other neighbors.

    Sure. You just don't have technically informed conversations.

    He has a fancy digital front-door lock that stopped working a few
    weeks ago. Dead battery? Code crash? I let him into my back yard, he
    jumped the fence, climbed up to a deck, and got in the back way.

    His solar panels don't make much power in our climate at our latitude.
    And they need maintanance.

    But the power that they do make more than covers the interest on the investment they represent. Finding somebody to buy it when they are
    making power is difficult - the utility companies don't like doing it
    for you, and won't pay much for it.

    Putting in a couple of kilowatt hours worth of battery can mean that you
    buy a lot less power from the utility company, which means that you get
    the retail price for the power you do generate, which is a lot hogher
    than the feed-in rate.

    He parked the entire array on our roof when he had his roof repaired.
    That was crazy expensive.

    We don't have many hurricanes or tornados here, but panels get ripped
    off roofs where people do.

    You have to design the mounting arrangements to cope with the worst
    cases stresses they are likely to see. Tornado take off roofs, so it
    seems that Americans don't bother designing for them.

    Electric car and solar panel purchases are mostly driven by government financial incentives here. China is the main beneficiary.

    That's not true in Australia. The fossil carbon extraction industry has
    a vested interest in lying to you about that, and we know that you are gullible sucker for their propaganda.

    Electric cars run at less than half the cost per mile of their combustion-engined equivalents. Hybrids - which run their combustion
    engines close to maximum efficiency- also offer useful savings.

    The batteries are expensive and don't last forever, but don't come close
    to cancelling out the advantage.

    John Larkin claims to be able to think, but isn't all that good at it.

    You substitute insults for thinking, and aren't very good that.

    You experience uncongenial intellectual insights as insults. They aren't
    designed to be insulting, no matter how much you dislike them. so you
    are judging them against an inappropriate criterion.

    Discuss some electronics. That's the topic here.

    I do that quite often. Much of what I do post does seem to go over your
    head. Your contributions to the very long low distortion sine wave
    oscillator thread weren't impressive.

    It's not difficult nowadays to make a variable-frequency 1-
    PPM-distortion sine wave. The problem is measuring it.

    The aim wasn't to make a variable frequency source, though it is
    possible to move the frequency a bit by feeding back a quadrature
    element in the same way you feed back an in-phase element to get the
    amplitude right. It is clearly possible and I have simulated it, but I
    don't know of anybody that has done it.

    Fourier transforms pick out the harmonics of the fundamental that are
    the distortion, making measurement relatively easy. Very sharp notch
    filters to get rid of the fundamental would do the same sort of job, but
    you probably would have to tweak them non-stop to keep the notch at
    exactly the right frequency.

    One ppm isn't a hard target to hit with a low distortion op amp.
    Jim Williams did better than that in one of his application notes using
    a FET as a variable feedback resistor as his gain control element. The
    main point of that exercise seems to have been to demonstrate how good
    the low distortion op amp really was.

    It would be an interesting hobby.

    Not all that interesting.

    Did you ever build your low-distortion oscillator? I wouldn't trust a
    Spice sim at that level.

    Never got around to it. I've still got the bits. There do seem to be
    people around that built similar circuits that did validate the Spice
    models.

    How about you? Do you enjoy 3D motion and acceleration? I think the

    A decent engine. Some units have a forged crankshaft and are very
    popular for modding. With the addition of aftermaket forged
    pistons/rods and a turbo it can achieve over 800bhp with a remap.

    Yikes. It's dangerous already. An it's true that bulls and cops don't
    like red cars.



    Most mass market cars with V6's and above have been taken off the UK
    market in recent years.

    Right. I don't like the turbo feel. "Nothing displaces displacement."

    I bought the Audi used with less than 20K miles on it. It was custom
    built for a guy who had six cars and then lost his job. His wife cried
    when he had to sell it.

    I wouldn't want to be stuck on the upgrade to Donner Summit, in a slow
    line, at 15 deg F, in an electric car. With the heater off.

    Why would you turn the heater off?

    To save battery energy in hopes of passing the summit at 7200 feet. It
    might take 20 hours to get a tow truck in a blizzard.


    Teslas are rarely seen in Truckee in the winter.

    Their owners are more nearly sane than people who buy Audi's?

    Batteries don't work well at low temperatures, and charging stations
    are far apart. If you park at a ski area all day, things cool off.

    We have seen some Teslas in clusters, looks like mutual aid convoys.
    Sort of electric wagon trains.

    Shoppers at the Truckee Safeway park in the charging stalls, since
    they are rarely used.

    Since you aren't much good at visualising circuit dynamics, this
    probably rates as one of your bad ideas.

    I played field hockey for decades and there's a lot of 3-d motion in
    that - I played goal-keeper quite a lot and the incoming ball does tend
    to be moving in all three dimensions. It didn't strike me as having
    anything to do with visualising circuit dynamics, where my time scale
    was a lot slower.

    I did say "the rational approach". Being rational is hard work, and few
    people bother.

    There aren't all that many of them on the streets in Australia. There
    are welfare services that look after people who need support, and
    begging is frowned upon as way of making a living. The UK and the
    Netherlands worked the same way.
