Quite right about the skin effect, but most of the world uses 50Hz (which makes the skin effect even more negligible)...don't know if this project envisions 60Hz or 50Hz or some other frequency.
lol even just playing the song "Thunderstruck" over drone footage flying over that gigantic NT solar farm would be a great promo video! The proposed solar farm allotment shown at timestamp 2:03 is 12 MILES long and 6 MILES wide (or 20 kilometres by 10 kilometres). Bigger than Manhattan Island! I want to see the drone footage!

The skin effect is miniscule at 60hz. The reason why they use DC is because of AC capacitive coupling. Basically, AC can conduct through non-conductors, but this effect is proportional to surface contact with another closely positioned conductor. This is a small but non-negligible issue when AC is transferred over long distances over land, where AC couples with the semi-conductive ground. It is still manageable, and is not much of a concern outside safety. Its only a big of a problem when these wires are placed in the ocean, where everywhere is extremely conductive salt water. Electrical power transfer over sea is always via DC to prevent this sort of capacitive losses.
THANK YOU! I was just about to comment on this. First time I see asianometry making a mistake :). All of Europe is one massive synchronous grid, but the UK is not connected due to the sea. They're connected with HVDC instead. As that's just a short distance, using HVDC would make no sense going by the videos explanation.
Was he right about the small losses using HVDC? Also, I'd no idea the Chinese were using HVDC above ground with power transmission from the 3 Gorges dam. I heard they were using giga-volt potential. Gigavolt DC equipment must be pretty impressive.
It's strange that the price tags of these monumental and important mega projects are in the same dimension as the acquisition of some app that gets aquired by some tech giant. Prices really are a strange thing. But II need help! I've been bingewatching this great channel for hours now!
@@rayhans7887 if the numbers are correct, you might might be able purchase a single aircraft carrier and perhaps a few F-35 aircraft for the cost of this project.
All acquisitions like that are priced based on future performance and not current current or past costs, especially in tech this has been a self-reinforcing spiral making everything crazy priced. These projects have costs based on actual real world things like resources and man hours, rather than fantasies of perfect performance over many years to come.
Enjoy your binge. The awesome thing about this channel is that there’s a lot more to come. Unlike TV shows that either get worse over time or just end.
The main issue with running AC underwater, is from induction losses since salt water is a good conductor, the cable acts as a large capacitor. This isn't an issue with DC
It can be develop to ferroresonance right? And i think main issue is Singapore is not friendly to Malaysia and Indonesia , then Singapore turn to Australia which make higher cost.
I like the idea of using a desert area as a major source of solar power. However, did I miss any mention of the risks of placing an undersea cable directly along the line of some of the highest seismic activity in the world?
There is also a plan to build a huge solar array near Pilbara in Australia and use its output to electrolyze water into green hydrogen. This will be liquified and shipped to other Asian countries, where it can be used to generate green electricity among other things. So there is an alternative way to eliminate the fossil fuels and not have to transmit electricity long distances. If you're reading this, I guess you should make a video about this plan.
For those interested, that project is called "Asian Renewable Energy Hub" and was originally another submarine power cable project (from Pilbara, Western Australia not central Northern Territory)
liquified hydrogen for export is nonsense, it takes huge energy to liquify it, their are no ships capable of transporting it and no infrastructure to burn it upon arrival. For less energy you can just synthesize hyrdocarbons from the hydrogen and ship that. Or utilize the hydrogen to directly smelt Australian iron ore into steel and export that.
If Australia wants to become co2 neutral using solar panels they would need a land area four and a half times the size of their country; professor Ian Plimer has crunched the numbers. I hope he sees this video he will have a good laugh.
@@Johnsmith-zi9pu a house can be fully self sufficient from solar just make it compulsory to build a house without it , but the government can’t steel your money so they would try to charge u tax for your panels yearly
@@trentbrady8829 Fully self sufficient???? A fully self sufficient house and that includes cooking, heating etc.would require a quarter of an acre of solar panels and a shed full of toxic batteries.It's clear you have no understanding solar.
Another big advantage of HVDC between countries is that you don't have to synchronise their grids which you can't even do if you're going between a 60Hz and 50Hz country.
As an Australian engineer the thing that I find most curious about this project is that they propose to export the electricity to Singapore - rather than use the electricity locally to convert it to other useful things (hydrogen, aluminium, fresh water, cement, steel.. etc). I think we'd do better exporting energy-embedded materials than simply the electricity.
It is a proposal from Singapore to import. It clearly says so in the description and content. Australian governments have been extremely hostile towards renewable projects. There is a lot of coal in Queensland. This kind of project would be out of character for any Australian government.
Well, if this project proves to be economical despite the extensive cable lengths, it could open up further possibilities. For example a nuclear plant in Alice Springs providing electricity for the entirety of the mainland so that Tasmania can then keep its hydroelectricity for itself
@@spdfatomicstructure Nuclear?? There would be too much opposition in Aus. As the video shows Aus has an abundance of solar and hydro, adding wind installations and related proposals, "big" batteries going in all over the country, nuclear is not needed.
@@TheHsan22 Solar does not produce power through the night. Coal power is still going to be needed for the night, and I doubt hydro would be sufficient to replace all the coal power. Nuclear power is the best solution, and everyone i've ever spoken to all agree. I live in Australia btw and i've never met anyone as far as I know who opposes nuclear power. I think it's the mining companies lobbying to keep coal power the dominate source of power because I don't think there is that opposition among the general population.
Thank you for your effort in delivering such a good presentation! Allow me to point out a minor detail, in that ABB did not exist in 1954. ABB is the result of a merger of Swedish ASEA and Swiss Brown-Boveri companies much later in the twentieth century. Cheers!
not just borderline insane, but truly insane. still, if it happens, some people will get very rich while the Australian taxpayers will suffer the consequences, though they wont suffer as much as the Uyghur slaves in the Chinese solar panel factories. No one in their right mind thinks this will use Australian made products.
An important point you miss here is that the per km transmission losses for an HVAC cable are much higher undersea than they are on land, which is not so for HVDC. So the breakeven distance for HVAC vs HVDC is FAR shorter underwater than on land. Basically noone builds underwater HVAC cables for more than a few kms - more than that and you need HVDC.
The Tasmanian cable failed because Bass Link cooked it by pushing it to it's limits to sell Hydro power to the mainland when prices were high. We would usually be OK for our power here in Tassie as we have heaps of hydro and wind power, but there was a drought on and they had run the damns down to risky levels. Although we have a backup gas generator it would not have coped, so Hydro Tasmania had to import a heap of contingency generators to guarantee supply (I knew the guy who was organising all this and it nearly killed him with the stress). Singapore would be well advised to have a workable back up plan if their cable from Oz failed.
I think they said 20% of total power so it actually would improve the diversity of the sources of supply but they would need some excess capacity to allow for failure in any of their sources including this one.
That is why the Gordon below Frankiln should have gone ahead. And it will sometime, when idiot Brown is dead, you watch, if you are still alive by then! How grows the Tassie population ?
So, all the Hoo Ha surrounding the Dams issue ( '"'Let the Rivers Run Free".... B. S. ) will, sooner or later be overuled by some 'progressive' govt. some day wanting to generate clean power for a burgeoning population of immigrants who won't care a twig for all Browns bull !
A good book on laying underwater cable is by John Steele Gordon, "A Thread Across The Ocean" on the first laying of the Atlantic telegraph cable, about 170 years ago. Same problems with cable and deep seas.
I think a bigger problem with AC, especially underwater, is that the cable forms a capacitor with the surroundings and thus there is an AC current to ground. The longer the cable, the bigger the capacitance, the higher the loss.
Australia vast desert is the perfect fit for solar farm, hot and dry help keep the maintenance low. And of course Australia is friendlier than muslim countries.
_" possible to have the solar/battery farm built in nearby Malaysia or even Indonesia?"_ I agree, it sound "complicated" and really Australia could use all "green energy" they can produce by themself and not export it, Australia have the highest CO2 emissions/capita in the world among "major" countries, even worse than the USA
this project delivers 20% of Spore total demand. Malaysia and Indonesia could also have similar projects to contribute some share and spread the risk and enhance regional integration. great topic.

A Q: If SG imports from 10 GW NT plant, what will happen to the local gas fired plants?
"A few rooftop solar panels on residential buildings. That is about it." - this statement is absurd. You certainly have not heard of Singapore's largest floating solar farm covering 45 football fields on our reservoir. It is also expected to reduce carbon emissions here by around 32 kilotonnes per year, the equivalent of removing 7,000 cars off Singapore's roads.
@@juniornutshell Geopolitics as in Indonesia would be the problem... if ever there's one. Otherwise, the only other foreseeable problem is the ever present islamic terrorism which has been wrecking havoc worldwide.

@@MoonLiteNite I honestly have no idea where you're getting your sources from. In regards to the 'murdering', the death sentence has always been reserved solely for drug traffickers(large amounts). Those found in possession(minor quantities) are always sentenced to rehabilitation instead. Drug traffickers are aware of the risks involved but choose to do so regardless due to higher prices in Singapore
Considering that Australia is basically the prime source for uranium in the world, it would’ve made a lot more sense for Singapore to invest in small modular reactors instead.
I stack my solar panels electrically to double the voltage and minimize transmission losses. Probably not making a huge difference even with my extra long coiled wire that needs to be trimmed to a reasonable length, but at least they kick on earlier and off later.
If anybody is interested, Singapore is supposedly not well-suited to wind power, with low-to-intermittent wind speeds (2 meters per second) where commercial turbines supposedly operate at 4.5 meters per second. Also the waters around Singapore are busy shipping lanes, so there supposedly aren't actually that many places to put the wind turbines.
On another note. Yes Singapore would not have the land mass to implement solar panels but it is surrounded by water. Makes a lot more sense to develope tidal currents to develope power. The water is always moving
Make.you wonder that's why hydro Tasmania sent a guy to Sarawak for this 20 dams they plan to build. Seems easier to build a massive cable than using illegally run govenrment to build massive dams
How expensive are either 1) Singaporean electricity, and 2) Indonesian land to make this economical? You'd think it would be far easier to make a profit from supplying solar to Australia, or building solar plants in Indonesia (it's not cloudy all the time), or to sell the electricity to Java and save thousands of miles in undersea cables
Exactly, coupled with aboundand Geothermal Energy in Indonesia there shouldn't be a problem for a shortend Sea Cable. Except, politics. Maybe Singapur doesn't like Indonesia OR it's a media stunt. Singapur and Australia are far more advertisable than Indonesia.
@@juliane__ Recently a Singapore public media published an anti/pessimistic Indonesia nuclear power source propaganda video. Instead of supporting their neighbor country or providing neutral insights from technology view, they just went stamped whole nuclear power technology as bad and all Indonesians as incompentent developing country people from politics and conservative environmentalist views. Little did they know, Indonesia is going to harness the safe thorium nuclear energy commercially by 2028 according to the current blue print. The nuclear power plant will be built in Bangka Belitung area which is really short to Singapore. In that video, they also worshiped solar energy as an only viable option. They neglected the geothermal potential completely. It's clear that they don't like us. Also the estimated electricity selling price from the thorium molten salt reactor is 0.7 cent/kWh and the current existing geothermal plant's is 6-9 cents/kWh. I wonder how cheap this Aussie solar electricity from the so-called Sun cable, not even counting the high sabotage risk on this long cable. The line must be very hard to break and very efficient to transport the electricity in 4500 km distance eh
Singapore gets its water from Malaysia right now and 81% of its natural gas (and thus its electricity supply) from Malaysia and Indonesia. See Asianometry's video "Singapore's 50 Year March Towards Water Independence" for more information on the water side of things... That reliance is already should be a **massive** national security concern. Given Singapore is a small city-state it realistically can't do everything within its borders. Even continent sized countries follow the economic principle of "competitive advantage" (not every country needs to make its own clothing, or cars, assemble its own electronics). So it comes down to diversification: never be overly reliant on the United States, China, Australia or the Middle East (for oil). Also Singapore has also passed a law saying no one source can provide more than 25% of Singapore's energy, and Sun Cable suggest they will only power about 20%
Singapore could become very dependent on this distant power supply, and if the cable is damaged, it could take months and millions of dollars to repair.

Sounds unbelievable. The cable costs must be horrendous. Unless Singapore has thrown its lot in with the 5-Eyes and Canberra sees Singapore as its forward post.
@@sampono1962 turns out the costs of climate change will also be borne by consumers... Singapore has to reduce carbon emissions somehow. Not a lot of good options besides this and maybe setting up more partnerships with Malaysia/Indonesia.
Singapore has reportedly passed a law that no single source can provide more than 25% of Singapore's electricity. That spread your risk approach seems to be how they approach international relations. They try to make sure their economy and security is not overly dependent on either the United States or China. Whether they are getting the balance right can be debated, but that's their strategy.
@@UltimateAlgorithm Traditionally , no one wants a nuclear power plant in their "backyard" and all of Singapore would be the backyard .

The big issue isn't transmission but storage. The video skims over nightfall. So what happens when the sun sets in Australia? Zero electricity traveling down the Sun cable. Singapore will still need power. Despite skimming over this, it is simply not possible to build any lithium battery large enough to cover for Singapore's nightfall sorry. Adelaide Australia installed the then world's largest battery in 2017 (Hornsdale Power Reserve). That battery can only power the city of Adelaide for 10 minutes. Singapore is 4 times the population of Singapore.
Great video explaining from the technicalities to the economics of the project. Seeing that Indonesia is along fault lines, any idea how earthquakes might affect it?
The Asian Renewable Energy Hub (a different proposal to the Sun Cable) is suggesting something similar after they changing from their original submarine cable approach. Solar + wind farm in the Pilbara region of Western Australia to produce ammonia and ship that over for "green hydrogen". The Sun Cable company is pursuing the (much cooler in my opinion) HVDC approach. Right now it's all private investors betting on these renewable energy megaprojects, so it doesn't hurt you if their investments fail. I'm glad there are people with the capital and risk tolerance to invest in these really exciting solar farm and HVDC submarine cable approach! For the sake of our carbon dioxide levels I hope they succeed :)
Maybe in the future when Hydrogen can be generated, stored and used more efficiently. Right now the entire process is much, much less efficient that simply transmitting the power directly.
That looks crazy, aren't Indonesia and Malaysia much closer? Wouldn't it be easier to produce energy in, say, Borneo ? Maybe it couldn't be solar, but there would be other alternatives, no? Like, say, hydro or wind.
Indonesia doesn't have a desert to create a solar farm and their waterfalls are not that large to create a surplus of electricity. Also Indonesia is more population dense than Australia, so electricity surplus is harder. Australia has a lot of advantages, in addition to other political reasons. Also Indonesia might buy electricity from Australia this way. Note that the proposed route also intersects the places that Australia has major interest. Indonesia still have had to agree though*. Edit: it's Singapore that hasn't permitted, not Indonesia
We have trial to import energy from Malaysia. www.channelnewsasia.com/news/singapore/singapore-importing-eletricity-malaysia-power-energy-13775308 Not one word from our government have been said of this. Other then mediaouts around the world tripping themselves making articles and interviewing the CEO, earning him free PR hype and potential investors.
Just goes to show, an insanely complex, expensive and highly risky project like this, is entirely unviable until people start yelling about climate change.
Importantly, Australia is politically stable and has a long history of supporting Singapore thought it's history. Importantly, support for Indonesia, has always been strong.
Indonesia has lots of geothermal electricity potential and it's way closer to Singapore than Australia. And geothermal runs constantly so no storage would be needed. Wouldn't that make more sense?
This whole project will never fly! The cost vs return will make it not viable. I work in the power industry and you would need massive load to return a profit to the investors. The skin affect is complete rubbish, this only happens at higher frequencies. Low frequencies at 50 Hz donot have significant skin affect. The capacitive/impedance losses with corona discharge issues with EHV are why AC will not be viable over this distance. Plus solar and batteries have not reached a real return for investment currently plus you need to transmit this energy for 1000s of kilometres. Complete pie inthe sky idea.
Very interesting report. In Sweden the government is realizing the big electrification by windmills all over the country and especially in the north. Beside destroying ”the last wilderness of Europe” it needs huge powertransmission to the south and to the European grid. We now know that sun and wind cannot save us due to the needed backup when wind and sun low - cold and dark winter neither works. The EU had forecasted 90.000 windmills around the Baltic Sea in their latest. Technical Report. Global players backing investments in “green tech” and generate a political fear in climate crisis. Lobbying/corruption. Renewables are not fossilefree if you study their lifecycle demand mining, manufacturing, installation and decomissioning. So why not use the small modular nuclear plants derived from the many hundreds you find in military vessels. They can consume old nuclear waste - no mining, compact in space, prefabrication, easy transport, safe cooling with air convection, placed where needed, heat for heating/cooling/desalination/waste Ideal for Singapore and others. Please do a video about this Kind regards Torbjorn Sjodin, Sweden
Not very likely, lots of practical problems. When Basslink got damaged by a dredge, the power went out for better part of year. Singapore would likely be better off building a nuclear power station, as reportedly Indonesia is planning.

Singapore is very aware of security issues and this piece of infrastructure is too easy to cut. Batteries and solar is a very expensive means of providing base load. As seen by the fact that it is none done on a large scale anywhere. Therefore This is not going to happen. It is only a publicity stunt by some billionaires. A better option is some hydro power stations on Borneo. Or a nuclear.
1 million VAC subsea is the way to go. It's been implemented onland from Moscow to Siberia in 1989. The challenge is subsea earthquake around Indonesia Island. If I was a Singaporen investor, I would invest in Kalimantan Indonesia instead.
Others have suggested that too, I suggest checking out the video at 14:13 and comparing the amount of sunlight Kalimantan receives compared to Australia, then Googling "Kalimantan weather report". To talk the investors out of building that undersea cable you have to convince them it is more expensive than building the solar farms five or more times bigger to produce close to same amount of energy. Earthquakes _might_ damage the cables, daily tropical storms _will_ cause problems for solar and wind power. Maybe they should look into geothermal and tidal energy instead.
1. Subsea cables cross tectonic boundaries all over the world. 2. And put the rainforests in Kalimantan at further risks when they are already in great danger? No way.
@@huaiwei Oh yes, that too. Australian Outback can easily fit these huge solar farms and the local environment would probably thrive with the shade they give. On Kalimantan you not only have to cut down the forest, but because the tropical weather reduces the amount of available light you actually need to build at least two farms to match the one proposed for Australia, meaning more forest needs to be cleared... But it gets better, as just about only way to calm down the people who would protest this project is to promote how it produces clean energy... Oh, wait... So next you would have to cut down even more rainforest to build more solar farms so the locals can get clean solar power too. Also, cutting down rainforests tends to cause erosion so the solar farms might get washed away by floods or destroyed by a landslide.
So, Singapore is going to run an extension cord to Australia. We did that in Connecticut. Long Island refused the construction of a power plant. So instead, they ran an extension cord from the power plant in New Haven to Long Island.
Why is Singapore not invest in nuclear power? Even if their source of electricity is derived from natural gas (95%), that is reliable and cost effective. There is great opportunity for them to invest in blue hydrogen coupled with CCUS if they are worried about carbon intensity. Blue and green hydrogen could easily use the same natural gas infrastructure (minor modifications).

This is an absurd project, the environmental damage in building the transmission infrastructure to Singapore, then you have the high voltage DC transmission. Just utterly dum. Singapore needs to get over its allergy (or disdain) to its neighbors and fund local solar, and wind and energy storage solutions.
what makes me absolutely furious is not the fact that "foreigners are stealing our power" or "foreigners are stealing our land" it's not that at all *takes a deep breath* It's the fact that our PM is doing his absolute best to push for gas to be used in our country when it's at the highest price recorded and we are trying to phase out coal, a major pollutant and there's Singapore, a small (by land size) saying "yes, F that stool sample" and going with what Australia is really known for, a lot of sunshine in baron hospitable land that grows nothing but twiggy stuff. I want our country to tax them (fairly) and use that revenue along with bonds and grants to build our own and power our nation and probably New Zealand with this idea, if they are prepared to pipe in electricity from a country that is further to them than China then we should be prepared to have one state sacrifice vast land and get revenue from other states as we connect a resilient grid. I am embarrassed for my nation, this should have been something that we offered them AFTER WE BUILT THE THING!

Australia's government can't even organise solar energy for its own people properly so I'll be very surprised if this projects gets up and running anytime in the near future
@@adrianhelyar3186 The problem with people advocating for solar power is that they are usually only thinking of home use. Industrial machinery in agriculture, manufacturing and various processes across the industry require massive amounts of power. Industry relies on industry, from construction materials, pharmaceuticals, electronics, metals etc. One tonne of aluminium requires the same amount of electricity that an average family uses in 20 years, then think of the power used by a metropolitan train or tram network, elevators etc. All the things that you put in your home and the home itself comes from an industry that requires this power. The sunlight might be unlimited, but the land for solar panels or wind generators and the materials to build them is not. The amount of land needed, even if every rooftop in any country was covered in solar panels is far larger then is realised. The construction of solar or wind generation is so large, that before we have finished building these facilities, 20 years or so on we will have to start replacing the earliest facilities. The idea that wind and solar can produce enough power for any industrialised country is only thought possible when you don't really understand the scope of what is required and those promoting this as the future are taking advantage of you.
The choice between AC and DC: Transformation of voltage in quantity needs AC, but this is changing. Until recently AC transformers were the only practical way. Switching generally easier under AC with large voltages and currents - AC has natural changes of direction. Large single conductor cables under water needs DC due fluctuating voltage and elec characteristics of water.. Small three phase cables with earthed shields are OK for short water crossings. Conversion DC/AC or vv very expensive, so economic only in big plants. When pushing insulation to it limits (ie for high voltages), DC makes better use of available maximum voltage and hence reduces line cost. AC systems have to run at the same frequency. Connecting two of them with DC allows each to be controlled separately. HVDC is attractive for 1. long distance at high voltage with minimum switching, 2. for large underwater cables, and 3. for connecting together two independent AC systems. Conversion is expensive, so if you can use all three reasons together, so much the better. New Zealand has a DC link between two main islands. Necessary for the water crossing, but taken advantage of for a long overhead line connected to it. Also allows separate frequency control in each island.
Japan is working on a similar project, but the electricity generated in Oz is first converted to Hydrogen, then compressed, and shipped to Japan. There the procedure is reversed to supply electricity. I wonder how Australian folks feel about the potential destruction of their homeland over these types of projects. A quote I learned years ago definitely applies to these types of projects: "The Law of Unintended Consequences."
@@MsEverAfterings Exactly, while not all of them are remote as the one in the video, most are in the middle of nowhere and are usually built on depleted and nonviable ex farming land for the ones somewhat near population. Nearly all the big ones are out in the middle of whoop whoop. My friend has worked on a number of these solar farms in Aus and most are literally nowhere on inhabitable land.
Have you ever been to Australia? Obviously not; if you had you would know that there is a whole lot of nothing outback with no people and thousands of square kilometers of semi-desert ! If anything, those solar panels will provide shade and moisture for a little more life to form/colonise the area !
Batteries take a lot less room than solar farms, so you would expect Singapore to have plenty of them to buffer the incoming power. Of course if the outage goes on for months (as in the case of Basslink) there's nothing that can be done short of having a redundant cable available. Or maybe they keep some of their old power stations around "in case of emergencies" and use it like backup generators.
Anything to do with transboundary is very difficult to do. For Singapore there are many available sources of renewable nearby. They are unable to tap it. There was a similar plan to tap into the Sahara Desert to supply energy to Europe, Never get the go ahead. It is cheaper to get energy source nearby. You have not take into consideration how much Singapore is willing to pay and the type of arrangement, take and pay etc. Singapore is not going to guarantee you take or pay. A power company in Singapore went bankrupt as a result of fluctuating in demand. A dream.
So this is basically, we want the power but not solar in our back yard. So lets spend big to stick it over there where we don't live. I got an idea...lets move the people to where the power is.
great video on a really interesting yet unexplored topic! I'm from Singapore and rooting for the success of these renewable energy projects - hopefully we can sort out the technical and political issues.
I've spent a fair bit of time in Singapore over the years, and loved it. However, maybe Singapore can start using less electricity...? Maybe Singapore could import cheap electricity from its neighbours instead....?
@@cerealport2726 If Singapore thinks it is more economical to import solar power from all the way from Australia instead of its neighbors, I think that says all you need to know how "cheap" the electricity is from its neighbors.
@@exoticredtadpole2713 They mostly use gas to generate electricity now, imported from their neighbours. It's cheap, certainly cheaper than building an interconnecter many times longer than the longest ever built, and only able to deliver 2.2gigawatts. You're obviously of average to low intelligence, and certainly not an engineer or scientist if you think this project is viable financially, or logistically.
I agree, but while Australia exports so much raw commodities, iron ore, aluminium ore, bituminous coal, anthracite, wheat, etc., it makes niche industries really difficult. We do not have a big enough market to support major manufacturing industries but high value high tech niche exports are what we should be aiming at. But that requires high levels of education. The average Aussie is so dumb. Finland is a good example of highly educated high value niche exporter. Twiggy's idea of exporting renewable electricity to Singapore was the spark for this post. It would make so much more sense to use the electricity to refine the raw materials.
