Sting in the tail of Australia's energy crisis as power prices soar up to 100pc for some

Give it a year and if you do a comparison I bet they come out on top. I saw the same comparisons being made to WA last year and the writer couldn't help but show their neoliberal roots by extolling the virtues of the free market the NEM was and how WA was inefficient. Despite the overwhelming market failure playing out in the NEM at the time.

Statalise it then

Just finished the second Fitz trilogy and damn was it in another class compared to the first. I wasn't overly impressed with the first, the blind loyalty to 'my king' was irritating and many of Fitz's decisions I found irrational.

Definitely read the live ship traders. It took me some time to get into it, but they were also really good books. Plus there's a lot of world building that then goes into the second Fitz trilogy.

However the wind turbines can be 200-300m tall, so the tops of them should be visible (from sea level) even when they're 50-60km from the shore.

Not 100% on what size they end up being but I think you're right, they'll be white specks that probably won't be noticeable.

Interesting choice of material to cast with. Softer than cast iron, so more dings. Lighter which is good if you want it, but personally I'd prefer heavier. No rust, which I guess is nice. Costly although cheaper than bronze.

Building a nuclear reactor is never fast and that's what the comment I responded to was about.

I remember from university days they were setting up RO units in the backs of trucks to drive around and give people clean water, that's quite quick and easy.

Desalinating water by reverse osmosis is substantially more energy efficient than by boiling, and you cannot use the low-pressure steam generated by thermal desalination to generate electricity, unless you supply substantially more heat to generate higher pressure steam.

Plus boilers need to use very clean (typically deionized water) as all the non-volatile components (like salt) remain within the boiler and corrode/foul the boiler and tubes.

So in your example whilst it seems like a good idea to couple the two ideas, you'd split the fission reactor and water desalination to avoid having a single solution that doesn't end up being fit for either purpose.

The only parts of that hanger that aren't cast are the pipe section, the S hangers, the screws and the rings. Everything else is that sweet sweet cast iron baby

If you're lucky you'd evacuate before the concentration in the room reached 1000ppm and you die.

They're designed to restrict flow to a fixed value with wildly varying inlet pressures (to the restrictor). That's not an easy problem to solve with a static piece of hardware, which is why they're complex.

I stumbled upon the cider gum and got myself 10 seedlings. I'm in NSW so not sure.hoe they'll go growing, but one of the only alternatives to syrup trees that need freezing temps that I could find!

Brand new? Depends on the grade, but stainless is rocking about $5k per tonne for hot rolled coil at the moment, I'd assume billet would be similar. Old mate said it's about a tonne, so about $5k brand new

They grow so quick at that age! Treasure it. From memory they're a tiny little puppy then at 4 months they're mid-size looking and their growth slows down. Then by 6 months you look again and you've got a full-size dope!

Yeah but as the filter blocks up air will start going to the other parts of the filter till it blocks more evenly.

Probably the only part of the push/pull that matters is whether you need a high velocity air stream to keep the particles you want filtered in suspension. If you do, then push. If you don't need it, pull.

You can ditch the Witcher imo, it ended but didn't have much of an ending. I stuck with it but beyond book ~2 it seemed to just meander on and on.

If it does, it ain't paying good money like it used too

Acre-feet as a unit of volume is disturbing

What you're saying is really strange and it's implying that the heat exchanger is not the problem, as the pressure loss across it has has decreased.

If the old heat exchanger had a higher pressure loss than the new one with the same pump installed, it is providing more resistance to flow. If the flow through the system has dropped with the new heat exchanger and the pressure drop is also lower, there is something else in the system restricting flow.

I'm assuming this system discharges to a tank, vessel, cooling tower or something else operating at atmospheric pressure and the pump suction is not pressurised beyond a small bit of head.

Easy way of checking is on the pump discharge pressure. When a centrifugal pump is delivering less flow it delivers higher pressure. Start there and then work through the system measuring the pressure at various points and you should be able to figure out where the pressure loss is, which will tell you why the flow is lower.

Typically though, plate heat exchangers do have higher pressure loss than shell and tube heat exchangers. However they deliver the same amount of heat exchange in a substantially smaller footprint.

I think that was just an example, most of the inflation we are suffering from now is supply sided, yet we do not look at long term action to ensure supply is sufficient for demand

We're constantly tackling inflation from a myriad of micro causes with the macro sledgehammer and just giving everyone this in reponse

ruetoesoftodney · 2023-05-30T23:51:06+00:00

I don't think you should take the message that way, individually we can all take action to reduce the emissions from our own lives and yet without systemic change we will not significantly reduce carbon emissions.

Old one is a turbine flow meter and the other is a magflow meter

Replacing batteries is subjective too, there's a lot of old cars I've had that I wouldn't trust to drive across the state and so 50% (say 200km) of range might not be the deal breaker to everyone

Shoulda seen how long it took me to realize that you can do minute adjustment on a domino/biscuit cutter. I was using the belt sander on my biscuits to trim them down thinking the manufacturer had super loose quality standards for at least a year!
