Like going to the dentist, mineral exploration and discovery can involve a lot of drilling and a fair amount of (financial) pain. And much like your friendly neighbourhood dentist, the longer it takes to understand what’s happening, the more it costs.
When it comes to getting information about the minerals and chemistry of a single drill hole, the process can take up to three months. This is because a typical setup involves: setting up the drill site, drilling, extracting rock cores, sampling and logging those cores and sending the samples to a laboratory (which is often a considerable distance from the exploration site) for analysis. Then there is the process of entering and analysing the data, popping the findings into a database and getting it back to the company, so they can make a decision – it’s more complex than a root canal and much more expensive.
To speed up the process of understanding the mineralogy and geochemistry of drill hole cuttings we developed a portable lab, one that can be fitted to the exploration drill rig and analyse in real-time.
Instead of taking three months this process now takes about one hour – that’s more than 2000 times quicker than the current arrangement.
We’ve called this technology Lab-at-Rig®. Developed in partnership with Imdex and Olympus Scientific Solutions Americas, this onsite lab can be fitted to a diamond drill rig and a solid recovery unit to drastically speed-up the process of analysing an exploration site.
The lab includes a sample preparation unit that collects solids from drill cuttings and dries them; X-ray fluorescence and X-ray diffraction sensors to provide chemistry and mineralogy of the sample respectively; and the capability to upload that data to the cloud for analysis, in less time than it takes to watch a movie.
The project came about back in 2011, when a group of researchers were watching a diamond drilling operation near Adelaide and asked a simple question: ‘what if we could analyse the cuttings separated from that fluid in real time?’ We now know the answer: we can save a lot of time and money.
And now, after two years of research and development we’ve just announced that we will be commercialising Lab-at-Rig® and bringing this technology to the world, with the help of our commercialisation partner REFLEX.
With the prototype becoming a reality, perhaps we should turn our attention to making dentist visits quicker.
The Lab-at-Rig prototype was developed under the Deep Exploration Technologies Cooperative Research Centre (DET CRC).
CSIRO, Imdex, Olympus, University of Adelaide and Curtin University are now working on the $11m collaborative DET CRC Lab-at-Rig Futures Project, which will build the next generation system to cover: new sensor technologies, improved data analysis and processing for decision making, and development of the system for new applications and drilling platforms.
Did you know we’re exporting our solar technology to the world?
Fresh from setting a world record last year, our solar team continue to see great demand for our heliostat technology. We recently took this tech and our expertise to Cyprus to help the island nation with its transition to renewable energy, and now we are off to the ‘land of the rising sun’, Japan.
Mitsubishi Hitachi Power Systems (MHPS) are establishing a field of 150 heliostats in Yokohama, for running research projects using CSIRO-designed heliostats. MHPS recently received funding from the Japanese Ministry of the Environment for the purpose of reducing carbon dioxide emissions, and we are delighted that this global leader in energy has chosen our technology; it’s a great vote of confidence.
But it’s not all about success overseas, our solar tech is making a difference to the local car industry as well.
We’re not talking about solar powered vehicles (though we are a fan of solar cars, in fact we’ve developed technology for solar powered cars and tested it at the World Solar Challenge). We’re talking about this technology empowering local companies to transition from the automotive industry to renewables.
We’ve been working with Adelaide-based company, Heliostat SA (HSA) to harness the same skills and equipment they perfected making car parts to manufacture our heliostats. It’s a perfect fit for a company looking to transition its skilled workforce into a new and lucrative industry.
Our heliostat design is unique. It’s smaller than conventional heliostats, and uses an advanced control system to get high performance from a relatively inexpensive design.
Heliostats are of course the linchpin of solar thermal technology. Consisting of a single mirror hooked up to a computer controller, heliostats work together in large groups – or arrays – to track, reflect and concentrate the sun’s heat onto a single receiver point. It’s sort of like using a magnifying glass to focus the sun’s heat to a point, except we’re not melting toy soldiers and ants. We use this heat to generate electricity, in this instance by heating steam to supercritical (550 degree plus) temperatures to drive a turbine.
This energy can then be stored cheaply as heat in solar thermal systems, giving this technology great potential for medium to large scale power – even when the sun isn’t shining.
This project is another example a decade of solar thermal research coming out of from our energy centre in Newcastle. The continued success and international demand for our technology continues to make a strong case for exporting our solar technology and creating more value for the Australian economy.

Being recognised as one of Australia’s ‘foremost visionaries’ for your work is, understandably, a pretty big deal.
But when you’re the brains behind an exploration tool that’s utilising superconducting quantum interference devices (or SQUIDs, for short) to locate more than $10 billion worth of mineral ore discoveries across the globe, it might help explain a few things.
This was the case last week for two of our very own researchers – Manufacturing Flagship deputy director, Cathy Foley and research scientist Keith Leslie – were awarded the prestigious Clunies Ross Award for innovation and commercialisation, thanks to their LANDTEM exploration tool.
This was a particularly momentous occassion for Cathy, who became only the fifth woman to win the award since its inception in 1991.
LANDTEM is a portable exploration tool that’s valuable for detecting highly conductive ores like nickel sulphides, gold and silver. LANDTEM uses the SQUIDs technology to differentiate the target ore from other conductive material or overburden, even for deeply buried ores.
It’s a far less invasive and more targeted technology then, say, drilling, so it’s more environmentally friendly. It’s also incredibly efficient: one company in Canada cut its exploration costs by 30 per cent using LANDTEM.
So, why do we care? Because valuable minerals are found almost everywhere, and they are essential to our life as we know it today. To put it in context, every smartphone contains about 40 different minerals; the average medium-sized car contains 19 kilograms of copper amongst a heap of other metal; and rare earths are needed for green energy products such as solar panels and wind turbines.
Minerals are also an important contributor to our national economy, and are our most valuable export business, worth about $119 billion.
While we have a wealth of mineral resources, these are finite and most of our deposits near the surface have already been discovered. That’s why we’re developing new efficient tools like LANDTEM to help explorers make valuable mineral discoveries needed for the future.
Cathy and Keith are continuing their valuable work by significantly enhancing the sensitivity and functionality of LANDTEM. Most recently they developed a new and improved version that will be able to detect ore bodies even deeper underground.

Electricity prices, poles, wires, peak demand. Pick any combination of words and you’ll find a raft of news pieces, heated debates and public protests. ‘Poles and wires’ was an issue that led the NSW state election this year, and bill woes led to 58,000 properties in Victoria being disconnected in a single year.
It’s an inescapable cost for the consumer and the environment. But it’s also one that can be managed, by quite literally taking things into your own hands.
That’s why we’ve developed a new system that takes smart metering a step further, allowing consumers to monitor their electricity consumption in real-time and control high-drain devices remotely using an online interface – on a computer, smartphone or tablet.
The system, known by its friends (and the market) as “Eddy”, is being commercialised by Australian company HabiDapt. Eddy will send consumers personalised insights and recommendations about their electricity use, and take part in demand management schemes with incentivised pricing for additional savings. Think of Eddy as your own efficient energy consultant.
This is a terrific example of the Internet of Things (IoT) – where real world items are made smarter by connecting to the internet – sadly not all IoT ideas are a winner: Wi-Fi diapers anyone?
We think Eddy is one of the more grounded systems to come out of the IoT trend. Using cloud-based software and mini smart meters, Eddy allows you to control your appliances remotely. You could even automate the process using the online interface.
The technology is based on our sophisticated Energy Management System, which has also been adapted for use on King Island’s Smart Grid.
The research group behind the electricity management system was led by Brad Sparkes (nominative determinism anyone?), who points out that houses with solar PV installations stand to gain even more, as Eddy can be programmed to prioritise running high-drain devices like pool pumps when the house is generating excess power. If the sun doesn’t shine for a few days, the pool won’t go stagnant, as the system is smart enough to recognise when to use grid power instead.
HabiDapt is currently trialling the technology in homes with solar PV systems in Perth, and is also rolling the system out with Ergon Energy in Townsville, where it is being offered to customers as ‘HomeSmart’.
While Eddy isn’t available to all our readers during the trial phase, we thought we would share some of our favourite energy savings tips:
- Use the Green Savings calculator to make your house greener. Use the tool to identify a variety of ways to save on energy and water costs plus a whole lot more.
- Use the cold cycle in your washing machine. Heating water during a washing cycle accounts for 90% of the energy use of the appliance.
- Be smart about using your dishwasher. Run the dishwasher during off-peak times (often overnight). Ensure that it is full and the dishes are stacked efficiently.
- Try not to use the dryer. Opt for a clothes airer or clothesline.
- Ditch the beer fridge. Sacrilege I hear you scream! But it will save you a heap of money.

Blessed with beautiful beaches and plenty of sunshine, it’s easy to argue that Australia is the lucky country.
Of all our major cities, Perth takes the cake as the sunniest with an average 3200 hours of sunshine annually. Even well-seasoned Melbournians, who live in our least sunny city, get to enjoy an average of 2200 hours of sunshine a year.
So it might not be so hard to believe that Australia is home to the highest solar radiation per square metre of any continent. Not only does this reinforce why ‘slip, slop, slap’ should be every local’s mantra, this high degree of sunshine means that we have some of the best solar energy resources in the world.
Right now, only 1.1 per cent of our electrical energy comes from solar, but this could soon change as new technologies come to market.
Solar cells – like the flexible kind we’re printing – are fast becoming an important player in the renewable energy mix. Thin and lightweight, solar cells can be plastered to almost any surface to harness the sun’s energy and bring you sustainable power.
Solar energy is a business opportunity for Australian industry that’s projected to be worth about US$160 billion internationally by 2023.
We’ve been working with Dyesol, a local small-to-medium-sized enterprise (SME) to tap into this growing market and help them become the first to commercialise a new kind of solar cell based on perovskite material.
Dyesol develops cutting edge, clean energy generation solutions for consumers and hopes to be able to offer perovskite solar cells as a competitive alternative to the more widely-used thin-film photovoltaic (PV) cells.
Perovskite solar cells are an attractive option as the material cost is low and they are highly efficient to manufacture. Yet, at this stage it’s uncertain whether the product would have stability and durability over the long-term compared to other solar cells currently on the market.
Together, we’re working to investigate this limitation and improve the process for making perovskite solar cells so that Dyesol can produce a high-quality, sought after product.
We’ve undertaken two Department of Industry projects together, where our flexible electronics experts were brought into Dyesol’s business to help them identify the best way to take the technology forward.
Now, through a longer term partnership, we hope to help Dyesol capture the opportunities that this technology – and our great solar potential – offers Australia and turn their idea into a profitable and globally competitive business.

Have you ever wondered what it would be like to see a solar field constructed in less than three minutes? Of course you haven’t, but what the heck, here it is.
This timelapse footage was taken on the south coast of Cyprus, where our team recently designed and installed a solar thermal field of 50 heliostats (mirrors that reflect the sun’s heat to a central tower) which could generate enough heat to boil a kettle in less than five seconds.
Super quick cups of tea aside, solar energy has enormous potential for Cyprus.
Being the southern-most member of the EU, the country is blessed with abundant sunshine. However most of the island nation’s electricity is generated – expensively – using oil, making solar an attractive option for power generation.
This is good news for Cyprus which, under European legislation, is required to derive 13% of its total energy consumption from renewable sources by 2020.
These are just some of the driving forces behind the Cyprus Institute’s decision to establish a solar thermal research facility at Pentakamo on the south coast, a stone’s throw from the Mediterranean Sea.
For the team in our Energy Flagship, this project was a big step, as it’s the first time we’ve deployed this cutting edge technology outside of our own backyard.
“We’ve developed a lot of confidence building our own fields,” said our solar research leader Wes Stein, “but we were glad to step out of our comfort-zone for the Cyprus Institute because we shared a common goal. They’ve been a fantastic partner, and in fact we’ve just signed a MoU to further the partnership and undertake joint solar research with them.
“The project has given us a strong understanding of how to deploy these projects outside of our own safety zone and into other environments. And that’s where we want to go, we want solar thermal to be commercialised by building on the good research that we’re doing now.”
With a unique and smaller than usual design, our high-performance heliostats are well suited to the rugged terrain on Cyprus’ south coast. They also give the user more control over the intensity of the solar concentration and versatile installation.
Solar-thermal tower technology uses many mirrors (heliostats) that accurately track the sun, reflecting light towards a receiver on top of a tower which heats a fluid. The heated fluid is then used to drive a turbine for generating electricity and, in the case of the Cyprus Institute’s research, also powering a sea-water desalination plant.
As thermal energy can also be stored relatively cheaply compared to other technologies, there’s great potential for large-scale power generation regardless of when the sun is shining.
The experimental facility in Cyprus will be used for demonstration purposes by the Cyprus Institute. In the longer-term, we will be looking into the commercial use of the technology for other Mediterranean islands and the Middle East.

On a sandy bank of north-western Australia, a flock of monstrous birds stride about in the shallow water — squishy, silty mud oozes up between their toes. Among their feathered numbers is a Woodstock of droppings, downy feathers, and clashing footprints. These birds are fearsome, toothed, tailed, and not birds at all, but their forebears: theropod dinosaurs, the group that contains the Velociraptor and T. rex.
The muddy sands that these animals walked in is now stone, and their tracks can be found up and down the 100 km stretch of the Dampier Peninsula coastline, also known as the ‘Dinosaur Coast’.
Those three toed bird-like theropod tracks are by no means the only prints around the coast. Some were also left behind by sauropods with feet that were 1.5 metres in diameter — that is 5’. At least 16 different types of dinosaurs left their impressions with thousands of tracks, even some from ghostly species for which there is no other evidence.
To garner all we can about these spectacular fossil tracks, the Walking with Dinosaurs in the Kimberley research project was born, funded through the Australian Research Council Discovery Project scheme. Headed up by Dr Steve Salisbury from The University of Queensland and Associate Professor Jorg Hacker from Airborne Research Australia at Flinders University, the project brings together an array of experienced and skilled groups including two of our researchers: Dr Robert Zlot, head of Robotic Perception, and George Poropat, Senior Principal Research Scientist in our Energy Flagship.
Together with Dr Mike Bosse from ETH, Zurich, the team is working closely with Goolarabooloo Traditional Custodians and Yawuru Native Title holders to help locate and map the tracks.
Our researchers have been helping the palaeontologists by documenting the 130 million year old tracks using sophisticated 3D imaging technology developed here in our Energy and Digital Productivity Flagships. They have also trained the Queensland team to use the equipment for independent expeditions with the resulting data being sent back to our scientists for processing.
Since GPS data are imprecise, other more specialised devices and techniques are also required. The highest resolution data are gathered by a modified photomapping technology called Sirovision and extensions to some commercial packages. These data can be used to generate high-quality 3D outputs of the subject providing sub-millimetre scale models of footprints.
On a larger scale, Assoc. Prof. Hacker scans the tracks using a specially equipped low-flying aircraft, soaring just 10 m over the rock platforms. The aircraft captures mapping data (high-resolution photos, video, and lidar imagery) as it flies overhead. The data captured by this aircraft can be georeferenced with those from the Sirovision device, enabling data of different scales and resolutions to be integrated.
And at yet another scale, we have the amazing Zebedee.
Zebedee is a handheld lidar (portmanteau of light-radar) that maps the environment as you walk. You simply meander through a site holding Zebedee as it beams out 2D ‘sheets’ of laser up to 15 metres into the environment. As it does so, it eagerly rocks back and forth on a spring, making those 2D sheets of information overlap again and again to form a dense and accurate 3D map of the environment. Zebedee initially arose from research into 3D mapping for autonomous robots.
As well as using our nifty Zebedee, Dr Salisbury and the team have also been using a drone to map the prints from above, a perspective on the animals’ movements impossible from human height.
The tides along the coastline are extreme, at some points drawing back 10 metres down the rock platform before creeping back again. The team must do their work in just a few hours before the tides rise up.
As well as recreating the tracks with high fidelity, Zebedee and the other tools and techniques are integral for preserving these wonders. The tracks are ephemeral and are constantly being eroded by the relentless sea. “A number of tracks that we have documented last year have disappeared as a result of sand movements during the 2014-15 storm,” said Steve.
The Walking with Dinosaurs project is science at its finest: palaeontological rigour, traditional insight, and sophisticated aircraft and imaging equipment. By using these cutting-edge technologies, scientists are simultaneously preserving and recreating an ancient world that would be otherwise unimaginable.
