Rather than "could", I would say "should" or more strongly, "must'. Establishing community batteries and maintaining a distribution network would cost money, no matter whose money it was. Who owns the distribution network at the moment? Is it government or private? Would it be acceptable for private companies to install community batteries and maintain them by charging a rent to "store" electricity for those charging the batteries with excess domestic solar generated electricity? The rent could be calculated on the amount delivered to the battery and the amount a household used when a premises' system was not generating. That withdrawal charge could also be applied to non-contributors in the same way that we pay for electricity at the moment.

A seemingly simple question, but one whose answer is incredibly complex. I think that Jerry has hit the nail on the head when he mentions "situational awareness", and consideration for others, which one could label as "courtesy". A practical definition of "speeding" has to include a reference to the environment in which a vehicle is moving. The speed limit in a carpark, or service station forecourt is the same as that applying to the adjacent road. However, 10 - 15 kph in a carpark can be taken to be a dangerous speed (toddlers running away; vehicles reversing out of parking spots). A speed of 118 on a freeway with a speed limit of 110 is much less dangerous to others. I believe that 100 kph is the correct limit for the open road, simply because it allows for good fuel consumption in most vehicles, as well as allowing for estimating arrival times at the next town. In urban areas, the frequent changes in speed limits is very distracting, especially if those changes are only of 10 kph. I'll accept 40 kph around schools and 50 kph in residential areas, then 60 and 80 on feeder and arterials. However I abhor 70 and 90 kph zones. As for a relentless policing of absolute adherence to speed limits, my opinion is that more acceptance of "herd mentality" should be made. What I mean by "herd mentality" is that when a platoon of vehicles is travelling along a road, the majority of drivers will travel at a speed which the consensus decides is "safe". That speed may be five to ten kph above the posted speed limit. It is the driver who tries to pass through the platoon and get further ahead who should be dealt with. The greatest danger to others on our roads currently is intoxication as a result of substance abuse. Drugs, both legal and illegal are present in more people now than in the past. One result of RBT has been reducing the number of persons driving with blood alcohol concentrations above 0.180 grams of alcohol per 100 ml of blood (High Range PCA). There are still people driving drunk, but not as drunk as people were before RBT. I repeat what I said in an earlier post - we need to recognise that operating a motor vehicle on a public road is as much a life skill to be introduced into the high school curriculum as being safe online, or dealing with interpersonal violence. Therefore, I say that driver education should be included as a part of the Physical, Health Education curriculum, even if that education only deals with the theory of motor vehicle operation.

I sin by driving in the right hand land of a stretch of overtaking lane - as long as there are no other vehicles about. Simple reason: the semis, B-Doubles and road trains make ruts in the left hand lane. They don't use the right hand lane, so the road surface is "smoother". I had sort of "sports' suspension, so avoiding rough surfaces gives me a smoother ride.

Do you get annoyed when you are driving Phillips head screw and your screwdriver slips? Leaving aside the effect of the amount of torque you are applying, there's another reason why the screwdriver slips. It's because there are three types of holes in the heads of the screws we typically call Philips head. I came across this video recently, and today I applied the information in it to select the correct driver tip to deal with screws in a tool made in England. After watching the video, can you tell me what type of screw I was dealing with?

A technical question. I looked up how a photovoltaic cell works at the photon level, and found that an electron is released when a photon strikes the molecules that make up the cell. I'm getting right down to the very lowest level of interaction. My question is: Photons are continually coming from the Sun, during the hours of daylight. Apart from things like sunspot activity, the concentration of photons should be constant for any given angle of the Sun above the horizon. Does that mean that the number of photons colliding with photoelectric cell is not diminished if it is a cloudy day compared to a cloudless day? To clarify my example. Suppose it is the moment of a day when the Sun is directly overhead a point on the Earth's surface. If it is a cloudless day, that should mean that the number of photons reaching the surface is a maximum. Now, at the exact same time the next day, it is cloudy. Would there be a difference in the number of photons reaching the surface? I wonder if the thickness of the cloud cover would make a difference.

G'day, mate!

FFS! Do you even comprehend what I write? Do I have to draw diagrams? I said that I wasn't attacking Albo. I was attacking the use of an Americanism in place of an Australianism. Because I have this obviously stupid love of a unique Australian culture, which I don't want bastardised by a foreign country which forces itself into places it is not wanted. I'm happy to see the culture evolve through the influences of those people from various cultures who choose to live here and contribute. I don't want to see that evolution thwarted by a culture which is a laughing stock and whose people don't have the sense to see how different reality is from actuality in their own land.

Well, he is the Prime Minister and that makes him the leader of the government. Say what you like about the truth or otherwise of his being the leader, but all I was trying to say that I hate the use of that particular phrase by Australians. If Valdemar used that American phrase, I would react in exactly the same way. Australians used to have a really good selection of appropriate phrases, but we seem to have lost the ability to free ourselves from the yoke of American culture, and are slaves to their terms.

I strongly support the introduction of Driver Education into our High School curriculum, with initial lessons, mainly theory relating to vehicle operation, beginning in Year 7. It's too late to begin this education when the kids are 16 years old.

John Marsden, Australian writer especially known for his young adult novel Tomorrow, When the War Began, which began a series of seven books, passed away this month (December 2024) - date not given. An English teacher at Geelong Grammar School's Timbertop, Marsden made the decision to write for teenagers, following his dissatisfaction with his students' apathy towards reading, or the observation that teenagers simply were not reading anymore. His first book, So Much to Tell You, was published in 1987. In 1993, Marsden published Tomorrow, When the War Began, the first book in the Tomorrow series and his most acclaimed and best-selling work. It was was adapted into a feature film of the same name that was released on 2 September 2010 in Australia and New Zealand. Marsden won every major writing award in Australia for young people's fiction. I well remember my daughter reading Tomorrow, When the War Began. She was n=more bookish during her teens, but I think my less bookish son also managed to finish it. I even think that I watched the movie.

And more water queueing up in the creeks waiting for a chance to flow in.

Not attacking Albo, but simply his use of the phrase. It's a terrible Americanism and could be replaced by something more in keeping with Australian language. For example, he could say, "Not while I'm running the show". That means the same, but is not a slavish following of a foreign style of speech. It shows a degree, however small, of independence.

I think that you have to get the 240V wiring in a caravan or RV signed off by a qualified electrician.
-
My guess is: Yes. Simply because a 240V electrical system can kill in a number of ways.

Doesn't he live in Southeast Queensland? If he does, he'd be too drenched to do anything.

I hate the insidious "not on my watch". Fair enough that it is a term used in the navy, and so it would be acceptable for it to be used by John F. Kennedy, Jimmy Carter, George H.W. Bush, Richard Nixon, Gerald Ford, and Lyndon B. Johnson, who all served in the navy. However, its use by politicians who did not serve irks me, especially when I hear Albo use it.

The problem with our democracy is that the majority of electors have the common sense, but their elected representatives (notice I didn't say 'leaders') do not.

Def'n: CONSERVATIVE: averse to change or innovation and holding traditional values. LUDDITE: a person opposed to new technology or ways of working. SYNONYM: a word or phrase that means exactly or nearly the same as another word or phrase. So are "conservative" and "luddite" in the consumable -v- renewable debate, synonyms?

Peeing.

It seems that the sensible answer for Australia is to concentrate on solar, which still works when the wind doesn't blow, and store the excess on battery farms. If we have a national grid, electricity produced in low demand places - mainly anywhere away from the major conurbations, can be transmitted through the grid to the high demand areas. It would cost money, but I wonder if creating battery farms would not be lots cheaper than trying to build thermal generating plants. Of course, my idea depends on advances in battery performance, which I do not doubt will happen.

War of the Worlds broadcast live at 8 pm ET on October 30, 1938, over the CBS Radio Network. The episode is infamous for inciting a panic by convincing some members of the listening audience that a Martian invasion was taking place.

Has anyone stopped to consider that the lights might be meteors? This time of year there are several well known, and well predicted meteor showers. Meteors contain a variety of chemicals which emit a variety of colours as they burn. https://earthsky.org/astronomy-essentials/earthskys-meteor-shower-guide/ If you view the web page you will see that this link describes Northern Hemisphere details for when to view the showers.
