Yes that is true. The comment I was addressing was this: So lets see what is going on with mining vehicles and machinery. For many mines, getting renewable electricity for crushers, conveyors, processing plants, camps and offices is relatively straightforward. The really difficult challenge is replacing the huge diesel haul trucks, loaders, trains and other heavy equipment. Where the industry is today Processing plants Many Australian mines are already running a large portion of their fixed equipment on renewable electricity because the power comes from the site's solar, wind and battery systems. This includes: Crushers Conveyors Mills Pumps Processing plants Workshops and accommodation facilities These are the easiest loads to electrify. Haul trucks The giant haul trucks are the biggest diesel users. A single large haul truck can burn millions of litres of diesel per year. The major miners are now trialling battery-electric trucks: BHP and Rio Tinto are jointly trialling 240–250 tonne battery-electric Caterpillar haul trucks at Jimblebar in the Pilbara. Fortescue has developed its own high-power charging systems and expects its first operational 240-tonne battery-electric haul truck to enter service in 2026. Fortescue is probably the most aggressive 5 Fortescue's strategy is not just to build renewable power stations but to electrify the fleet as well. The company is: Building more than 1.4 GW of solar generation in the Pilbara. Installing large battery systems. Deploying battery-electric haul trucks. Operating electric excavators. Testing electric dozers, graders and loaders. Their goal is to eliminate fossil fuels from their terrestrial iron ore operations by 2030. Mining railways are also beginning to electrify. BHP has taken delivery of Australia's first purpose-built battery-electric heavy-haul locomotives for testing on its Pilbara rail network. These locomotives use large battery packs and regenerative braking. How much diesel is still being used? For most Australian mines today: Equipment Renewable/Electric Status Processing plants Often 50–100% renewable electricity Site buildings Often 50–100% renewable electricity Conveyors and crushers Often renewable-powered Light vehicles Increasingly electric Excavators Early electric deployment Haul trucks Mostly diesel, some electric trials Trains Early battery-electric trials Drill rigs Limited electric deployment So when you hear that a mine is "80% renewable", that usually means 80% of its electricity, not necessarily 80% of all its energy use. Diesel trucks can still account for a very large share of total energy consumption. This is one reason critics sometimes argue that mining companies overstate their progress, while the companies respond that the technology for replacing 250-tonne haul trucks is only now becoming commercially viable. The next five years will probably determine whether battery-electric mining fleets become mainstream in Australia.

The trolley wire Kiruna trucks were quite popular in Europe. But they failed at Mt Isa as they produced too much heat from braking downhill. They did not have batteries, just produced the braking effect by sending the power into big resistor banks. Many mines in Europe and Canada have heaters at the surface just to stop the intake shaft from freezing up.

This is pretty impressive: an electric mining truck that does not need to be charged. Note, though, that it only works in a specific setting. The trick is that it travels uphill empty and downhill fully laden. Through regenerative braking, it generates more than is required to travel uphill again (empty)

Trailing cable electric excavators have been around for fifty years at least.all the really big shovels and draglines are electric. Also the bucket wheel excavators in the Latrobe Valley. Electric wheel haultrucks, with diesel engines driving generators, were developed in the 1960s and widely used. Underground, we had trolley wire electric haul trucks from Kiruna at Mount Isa in the 1980s. The first trolley wire electric locomotives were used in Victorian gold mines and at Broken Hill South from 1902 onward.

Don't be ridiculous, it obviously means keyboard players 😁

Does it matter OT? Personally I am proud of our mix of historic British words and the historic indigenous words that make Australia different from the US or Canada or NZ or Britain.

Excise is to Make and repair roads. If you don't go on roads, why should you pay the excise? . Nev

I guess what is new are battery-powered trucks and autonomous trucks, such as in China and Canada.

I believe there are electric vehicle operating in mines in Australia right now. Battery-electric mining vehicles are operating in Australian mines today, but battery-electric haul trucks are mostly still in the trial or early deployment stage. Already operating today Fortescue is operating: 16 electric excavators in the Pilbara Electric drill rigs Various smaller electric mining equipment being tested and introduced into service Fortescue says each electric excavator saves about one million litres of diesel per year. Battery-electric locomotives are also now being commissioned on Fortescue's Pilbara railway. These are not prototypes sitting in a workshop—they are being prepared for operational use on the rail network. Giant haul trucks (the really big ones) This is where things get interesting. BHP, Rio Tinto and Caterpillar are currently trialling two battery-electric Cat 793 haul trucks at the Jimblebar iron ore mine in the Pilbara. These are 240-tonne-class trucks operating in real mine conditions, but they are still part of a formal trial rather than routine fleet deployment. Fortescue has fitted out its first battery-electric Liebherr T264 haul truck and has commissioned a 6 MW fast charger capable of charging a truck in about 30 minutes. However, Fortescue has stated that its first operational battery-electric haul truck is expected to enter service later in 2026. So the answer is: Equipment Operating in Australian mines now? Electric excavators Yes Electric drill rigs Yes Battery-electric locomotives Yes (commissioning/early operation) Small electric mine vehicles Yes 240-tonne battery haul trucks Trialling now Large battery haul truck fleets Not yet The biggest surprise for many people is that excavators may electrify before haul trucks. An excavator works in a relatively fixed location and can be supplied power more easily, whereas a haul truck may need to climb several hundred metres carrying 200–300 tonnes of ore, making battery size, charging speed and mine-site power infrastructure much more challenging. If you're wondering whether these trucks actually make economic sense, the answer appears to be increasingly "yes" for remote mines. A large haul truck can consume several million litres of diesel over its life, so even expensive batteries can be worthwhile if charging infrastructure and renewable power are available. That's one reason companies like Fortescue are pushing so hard—they believe electrification will eventually reduce operating costs as well as emissions.

"Does it matter OT" Sorry OT I meant OME

There's Hundreds of different aboriginal Languages and No one could know all of them. Nev

Of Course. Farmers don't pay it either on farm use vehicles. Nev

Yeah, but the Maori language is still a living language. I don't think that any of the indigenous languages of the Greater Sydney Area are still spoken.

Excise is sent to general revenue and should be paid by all. My boat does not use roads, should I be exempt? No.

Only half of petrol tax is going back into roads say motoring groups, amid calls to cut fuel excise

It reminds of when we visit our son in NZ. One of our favourite places to visit is Te Papa Tongarewa which is Wellington museum. The literal translation is "container of treasures" I think it is a great name being both an understatement and a name that is quintessentially NZ.

The words identifying places in the map that PMCC posted are not locality names. They are the names identifying galleries in the Art Gallery. Got nothing to do with actual indigenous people. There's nothing wrong with applying an existing indiginous name to a locality. "What's in a name?" Romeo and Juliet (Act II, Scene II). The name Gilgandra originates from an Indigenous word meaning "long water hole", which is a waterhole in the Castlereagh River alongside the main street. There are plenty of places in the local area that are of indigenous origin. Say the name and people can identify the location.

There's probably 100's of Aboriginal place names already.. Nev

Update your data, GON. The Yanks want to create a massive arsenal storage in the middle of Victoria, and they are servicing their subs in W.A. Don't forget Tindall and Pine Gap. What's going on around Townsville?

The economics would quickly change if they paid excise on fuel like they should..

The Fed govt said there'll be no US bases in Australia ... but look what we've got now, thousands of Yanks and their military equipment stationed up north. Or does every one of them piss off at the end of a joint training exercise? I don't think so.

I wonder how many people in the vicinity of the Art Gallery of NSW speak the Gadigal dialect of the clan that occupied that particular area in the past. I suspect none, and that any descendants have long since moved away.

I read where Twiggy went to Caterpillar and asked them to build him a fleet of battery-powered big haul trucks. But they refused, saying the idea wasn't practical. So Twiggy went to Liebherr and asked the same question, they said "Yes" - so Liebherr are building the electric haul trucks for Twiggys operations. But 240 tonne trucks are only modest-sized trucks in the scheme of things. 400 tonners are common in numerous big mines. Cat did develop the "hybrid" diesel/electric D7E tractor in 2009, and have sold quite a few of them, about 10,000 units I STR. But the electric D7E has a diesel engine driving an alternator, which then drives a big electric motor, which drives the tracks - similar to diesel-electric locomotives. Essentially, the only savings with a diesel-electric crawler tractor or haul truck is in the transmission cost, with reduced costs as regards manufacturing and repair costs - and a fuel saving from the engine running at a set speed. The cost savings have to increase in the long run with all-electric power, although the up-front costs for electrification are massive, and the battery costs are also horrendous. It's yet to be revealed what battery technology Liebherr are going to use in Twiggys haul trucks - whether it's Lithium or Sodium. The Sodium batteries are starting to catch up to Lithium as regards power output, and they're much cheaper. But the Sodium batteries are heavier. In a mining truck application, the weight factor may not be such a problem as one might envisage.

Is that someone doing the ironing? Busy place.

It's obvious then. You're language-deficient, and need more training in obsolete languages and cultures. We'll book you in for a course in reading Sumerian cuneiform next week, so you can keep up, when they start using it for directions and nomenclature as well.

And this is the sign on the dunny door. It means one in all in and you can identify a anything you want.

Visiting the art gallery to see the Archies. Map they gave us is not all in my language.

Don’t confuse site power with total power which includes loaders, trucks etc.

Australia has quite a few mines that either run partly on renewable energy or are among the world's leaders in renewable-powered mining. Very few large mines operate on 100% renewables all the time, but several are regularly achieving 50–90% renewable penetration and occasionally reaching 100% for extended periods. Major Australian mines using renewable energy Mine Commodity Location Renewable Energy System Renewable Share Agnew Gold Mine Gold WA Wind, solar, battery, gas microgrid Typically 50–60%, up to 85–95% at times (Australian Renewable Energy Agency) Bellevue Gold Mine Gold WA Solar, wind and battery hybrid system Designed for ~80–90%; achieved 155 consecutive hours on 100% renewables (Reddit) Kathleen Valley Mine Lithium WA Solar, wind, battery, gas hybrid Around 60–80% renewable energy (The Australian) Mt Weld Mine Rare earths WA Renewable hybrid power system Reportedly exceeded 95% renewable share during one quarter (Reddit) St Ives Gold Mine Gold WA Large solar and wind project under development Expected to provide over 70% of site power (Reddit) DeGrussa Mine Copper/Gold WA Solar farm with battery storage One of Australia's pioneering renewable-powered mines (Australian Renewable Energy Agency) Weipa Mine Bauxite QLD Large solar installation Partial renewable supply (Australian Renewable Energy Agency) Tropicana Gold Mine Gold WA 24 MW solar, 24 MW wind, battery system Significant renewable contribution to mine power (Solar Now) The leaders Agnew Gold Mine Often regarded as the pioneer. It was the first Australian mine to use large-scale wind generation as part of a mine microgrid. The site combines: 18 MW wind farm 4 MW solar farm Battery storage Gas backup It typically obtains 50–60% of its energy from renewables and can reach much higher levels under favourable conditions. (Australian Renewable Energy Agency) Bellevue Gold Mine Currently one of the most ambitious renewable mining projects in Australia. The mine recently reported operating for 155 consecutive hours (over six days) entirely on renewable energy with diesel and gas generators switched off. (Reddit) Kathleen Valley Lithium Mine A good example of a new-generation mine being designed around renewables from the outset rather than adding them later. It uses a large solar-wind-battery system and has reportedly achieved renewable shares above 80% in some periods. (The Australian) An interesting pattern Most of Australia's renewable-powered mines are in remote Western Australia. That's because: Diesel fuel is expensive to transport. Many mines are off-grid. WA has excellent solar resources. Wind and solar can often generate electricity more cheaply than diesel generation. As a result, renewable energy is often adopted primarily for cost savings and reliability rather than environmental reasons alone. The economics can be very attractive for remote mining operations. (Australian Renewable Energy Agency) If you're interested, I can also list the major iron ore mines (BHP, Rio Tinto, Fortescue) and explain how far they have progressed toward running on renewable energy, because the Pilbara iron ore sector is currently undergoing a huge transition.

I can recall one wartime aviation hero, he survived the very worst of battle, and came home unscathed. Before he even went to War, his Anson and another, collided in mid-air, locked together, and he brought both crippled aircraft down to a safe landing, earning many kudos for his skill. Then, after returning from War with a DFM, he was sent to a training unit at Sale. But he collided with a bus on his pushbike in March 1944, and was killed. His name was F/O Leonard Graham Fuller.

A lot of industries are already exploring renewables and some are already off grid such as parts of the mining industry. As solar and batteries get cheaper, it will be irrational for households to connect to the grid merely to support the grid for the benefit of industry.

We had our local show this weekend. I got the chance to speak to representatives of the mob which is in the process of gaining approval for an eighty-tower windfarm within 20 kms of my place. Eighty towers seems like a big crowd, but when I was shown to proposed location of each tower, I saw that they were separated from each other by close on a kilometre. My first thought when I heard of the proposal was that teh towers would be visible from the Newell Highway which is located to the east of the proposed area. I learned that the closest tower woulod be about 5 kms from the highway, with a line of low "hills" between them. So that's no longer a concern to me. I think I've whinged before that around here it can be pretty windy, nd said that it would be ideal for a wind farm. Seems I'm right in some ways and mistaken in others. I experience wind as air movement within about 10 metres of the ground surface. That air movement is very turbulent compared to air movement 100 metres above ground where the turbine blades are. That turbulence, caused by the moving air particles colliding withthe ground and trees and ricocheting into air particles higher up. These collisions rob the air particles of energy due to loss of momentum. If the air movement is free of the turbulence, then there is more energy for the collision between the moving air and the turbine blades. That's why the towers are so high. I was also told that studies locally have shown that the most consistent air movement begins at these heights after sunset and stay pretty good until just before dawn. That means the turbines are best able to produce electricity at night in complement to solar panels. That sounds good. What about the effects on farm incomes? The builders don't resume the land they need like the government does when it wants to build roads etc. It seems that the land is rented from the landholders at a rate determined by the generating capacity of the turbine. An example was that of a property with two towers on it. Based on the generating capacity of the intended turbines, renting the land for two towers would return $100,000 p.a. CPI-indexed for a contract period of thirty years. That's got to provide a degree of stabilisation of farm income. I bet any landowner would love to get that sort of money, especially in the present circumstance when it looks like a drought is on the way. Why does it take so long to get a windfarm up an running. Would you beleive that it is in part due to the very people who pursue a renewable world? One of the environmental reports required deals with the effect of the turbines on bats and birds. Getting the data required a study lasting two years. Then there are the Native Heritage studies and gaining clearances from the local indigenous community. Then there are the geo-technical studies, planning permissions yadda yadda. We should consider the economic benefits. It is said that the workforce required to create the windfarm complex is about 500 persons. These people will be newcomers who will have to be fed, housed and entertained for several years. Already the local Council has allocated an area for an accommodation camp. Someone has to build it. An extra 500 people will hopefully boost local trade, although the proximity of the City of Dubbo, about 30 minutes' drive away might not do good for my town. Still, it's money coming into the district. In my opinion, there is nothing wrong with this project. Really, it is going to be 'out of sight, out of mind' to teh majority of the population. And kn owing what I know about smart crows and blind bats, I don't envisage too many mid-air collsions with revolving turbine blades.
