    My post is not in support of PC nor is it against PC; it is an observation of human behaviour. Darwin's theory is about the survival of the fittest, AKA every person for themselves. Any conclusions someone wants to draw from the observation of human behaviour are their own conclusions. By the way, civilisations rise and fall, there is nothing new about that. Nor is there anything new about the antecedents to the collapse of civilisations, which follow a regular path. Ignore history at your...

    Wasn't the election of Trump was the result of an overwhelming groundswell of anti-PC? That didn't seem to work out too well for many/most of its proponents. The anti-PC movement seems to be a exemplary example of Darwinian evolutionary theory unfolding in real time. What would be a lot more useful for the middle class is an anti-corruption groundswell, but that is probably too PC.

    In November 2020 Morrison said the guvmint’s Covid-19 strategy would put “Australia at the front of the queue for a safe and effective vaccine” and in January 2021 he announced four million would receive the vaccine by the end of March 2021. Sure there were hick-ups with supply but as late as March Health Minister Hunt was still saying “this does not affect the pace of the rollout” and was backed up by Morison along with the claim Australia would be "fully vaccinated by October". Now he isn't...

    The basic principles in acoustic damping are weight, volume and space; weight as in grams per square meter, volume as in depth between outer surface and wall (or window) and space as in square meters of cover. Natural fibres like wool, jute, linen, etc are more effective than synthetics, weight is gained by gather, as is depth. Natural fibre curtains at least double and preferably three or more times as long as the space they are covering in as heavy a cloth as possible, or multiple layers, are...

    Low-e glass is great for reducing radiative heat transfer through glass such as heating from direct sun in summer. Don't expect much reduction in internal heat loss in winter and you will not be disappointed. Fibreglass insect screens will also slightly reduce heat gain/loss in the absence of air movement AKA wind or breeze. Secondary glazing is often a great low cost upgrade, especially for timber framed picture windows. For a sash window it may be possible to install a second custom made sash...

    It should be easy enough to check the price of vlam glazing units. Although I am not familiar with pricing for IGUs four panes for $1200 doesn't sound excessive for a custom made product that will save you money and give you comfort until you die. My view is that the sooner you spend the money on IGUs, the sooner you reap the benefits. Prices for doubling glazing and energy for heating/cooling are only ever going to go up, and once you retire disposable income is only ever going to go down....

    It makes some difference to possible solutions if you trying to keep summer heat out or winter warmth in. Geelong? I assume you are trying to stop heat loss in winter. Also what type of noise are you trying to keep in or out, or absorb?

    The suggestion not to engage in conversation with others might not be bureaucratic subversion, but just something to do with aerosols being the main vector for transmission of Covid. There are other means of communication that don't require mutual sharing of pulmonary aspiration, such as phone, email, sms, twitter, etc.

    I don't know this model in particular but in general the Tastic's fans shake the lights and heater filaments until they fail prematurely, the extraction rate is poor, they are noisey, you can't see your face in the mirror as the light is useless downlight from behind you, the heat level is marginal and they soon become ghastly three-dimensional sculptures of spiderwebs and dust. Having said that, some people love them - go figure...

    When I scanned around on the topic I read that pure H2 isn't suitable for diesel engines, the problem being that H2 ignites at far too low a temperature to have high enough compression ratios for the diesel cycle to be worthwhile (efficient). A hydrogen/oxygen mix injected at the right time into a conventional diesel engine can improve performance and emissions.

    Where does the energy to produce this hydrogen for the revolution in ICE vehicles come from? The mechanics of creating, storing and using hydrogen for ICE engines means that around 2 times as much energy is required per kilometre compared to the energy used by BEVs from the same energy source. Range is an issue with hydrogen fuel requiring about three times the volume of petrol even when stored cryogenically at minus 253 degrees; so far the energy storage in batteries for BEVs is quite...

    Some electric cars have fake internal combustion engine sounds, now there is a fake petrol smell. A Ford-commissioned survey claims one in five drivers said the smell of petrol is what they’d miss most when swapping to an electric vehicle, “with almost 70 per cent claiming they would miss the smell of petrol to some degree”. “Petrol also ranked as a more popular scent than both wine and cheese, and almost identically to the smell of new books” among car enthusiasts, said Ford.

    So the death rate from Covid is running at about 10 times that of influenza, and unlike influenza 'recovery' from Covid often leaves severe health consequences including heart failure, respiratory problems caused by scar tissue in the lungs, strokes and increased risk of Parkinson's and Alzheimer's disease. Covid is more contagious than influenza and infected people remain infectious for much longer. Nope, can't see why it should be treated differently to influenza - NOT!

    Funny how all of the Dan Andrew bashers have gone quiet now that NSW is the epicentre. Perhaps the NSW premier's real name is Glandrew Berejiklidan. The reality is that just as poker deals hands, so goes the spread of covid. Politicians have sweet FA to do with spread, but everything to do with response. So where is our grandiloquent leader?

    The energy will be a small fraction of what the solar farm is going to generate and deliver or it simply would not be viable. It's several decades since the energy embedded in a solar panel was a significant proportion of what it would produce during its functional design life. Today's panels will produce as much as 30 times the energy taken to make them and even after that, when their output has fallen a little, properly made panels will continue to produce electricity for decades more. ...

    Which part? That a father died? That the deceased was asked what he wanted on his death certificate? Or that there is a conspiracy to inflate the numbers of deaths caused by covid, not just where covid is a co-morbidity? BTW it isn't stated whether the person actually had covid.

    I suspect it is not true that recording of of covid deaths in th US has impacted significantly on recorded mortalities from other causes, one reason being the number of covid deaths isn't big enough, another being how deaths are actually recorded as opposed to how a bunch of people on a renovating forum might speculate about how they are recorded. For a start, co-morbidities are routinely recorded whether covid is involved or not. Have a read here: ...

    Your explanation does not cover the circumstance of Marc's dubious post. But should I be disappointed then that neither I nor my 89 year old father was giving the option of what was recorded on his death certificate when he passed, or that of my sister who was also given no say?
