    You'll probably find a more informative message in a log file or output file.

    Australia electricity grid Nov 27

    Tom is quoting the idiot-in-charge's justification for why renewables are cheap. Of course they still haven't come up with costing to support that.

    I think all 4 lines basically just saying the optimisation failed.

    Things are Starting to Heat Up - Part XIV

    Talking of islands vanishing under the sea, surveys find that the atolls are in general growing not sinking. But you knew that, you just declined to mention it. The Maldives are building 7 new runways.

    Flow batteries

    They've been a bit of niche product to date, but it looks like if you can't sensibly have pumped hydro, using pumped vanadium electrolyte is a somewhat lossy but easily scaleable alternative. https://www.yahoo.com/news/batteries-could-harness-wind-sun-172548718.html

    What cuased the Little Ice Age?

    One of the major embarrassments for hockey stick/ anthropogenic warming enthusiasts is the Little Ice Age (and the Mediaeval Warming Period), which demonstrates that massive shifts in temperature are unrelated to CO2. Well here's some people think they might have an explanation for the LIA at...

    BEV adoption rates and factors that enhance or detract

    I believe Tesla fines you if you overstay. I doubt it would be hard to include dynamic pricing for chargers, based on the number of vehicles waiting, and your SOC.

    Net Zero Crash test dummy #1

    From the WSJ. To be fair Australia is #1 in some ways, we can't import leccy from outside. ‘Climate Action’ Has California’s Energy Economy on Its Knees While posturing for coastal progressives, Gov. Newsom punishes Central Valley farmers and industry. By Edward Ring Nov. 29, 2024 1:05 pm ET...

    Things are Starting to Heat Up - Part XIV

    A heat engine must be driven by the delta between hot and cold reservoirs. Since the Arctic has been warming more than the tropics it seems unlikely that at least at a hemispherical level there is more energy going into the atmosphere.

    BEV adoption rates and factors that enhance or detract

    Some journo in the UK observed that the shortage of public chargers is exacerbated by the drivers who want to charge to 100% which takes much longer than 90%.

    Things are Starting to Heat Up - Part XIV

    Problem is that the IPCC says it has low confidence that there is any connection between global warming and any change in hurricanes, and as I've posted many times, there's no trend in the graphs. There is no strong evidence of century-scale increasing trends in U.S. landfalling hurricanes or...

    BEV adoption rates and factors that enhance or detract

    Well yes and no. Many things take half a decade to get into production even after they have been officially blessed. So to some extent they do have to crystal ball a fair amount. But yes the worst (possibly) thing that ever happened to US OEMs is quarterly reports to Wall St.

    BEV adoption rates and factors that enhance or detract

    "why are the OEMs still betting so heavily on EVs?" Sunk cost fallacy and a reluctance to admit their wisdom was limited. The boards drunk the Net Zero Kool Aid, especially VW and Ford, and deemed in the face of raised eyebrows of the mere minions that BEVs were the future. Having decimated or...

    Another mechanism found that they forgot to put in the models.

    As we know the climate models that make the scary predictions are heavily fudged, partly because they don't include messy things like clouds. So here is one aspect they are missing- sulphides emitted by plankton that inititiate cloud formation. Despite being among the most studied climate...

    So dik thinks a plot of temperature indicates something or other to do with the frequency or intensity of storms. So, on the dik fatuousness scale Irrelevant 10 No source 10 No logic 10 Wow 30/30 Well done dik - a perfect post. Keep it up.

    Vehicle Anti-lock brake rotor system, increase horsepower, Brake Rotor takes 175 ft-lbs, 36 Hp to spin up, really? free wheeling the brake rotor

    OK, I'm gobsmacked by the weight. Meanwhile the rest of the world is fitting carbon fibre wheels to save 10 kg? Yeah sorry the agony of working in imperial means I have no feel for the right answer. Wagging it In metric I is about .6 kg m^-2, T=21*.6=12 Nm Hence power is 115*12 W, about 1.5...

    Remote SE Work

    Not an SE but I have remotely mentored two overseas employees who joined our team (not simultaneously). That worked, but only because the first 6 weeks or so of any given gateway is fairly slack, we are gathering information, and so the mentorees, working on a different program with different...
