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.
Let us know your favourite power-saving tips in the comments section below. If you would like to find out more about Eddy, visit Habidapt’s website. To learn more about our work in energy, head to our website.
Do you you think you eat enough vegetables to shame a goat? Does your self-restraint when it comes to curly fries make you a smug dinner companion? Or are you an unabashed chocoholic, throwing caution to the wind when it comes to all things cocoa? We all feel varying amounts of guilt and pride about what we eat, but how often do we make an honest assessment of our diet and think about what we could do better?
Well, now’s the time with our new online assessment tool that allows you to measure the quality of your eating habits. Introducing the Healthy Diet Score (HDS).
The HDS is a simple validated scoring system that we hope will help individual Australians measure the nutritional quality of what they eat. The score has been designed to measure whether a person is achieving the food recommendations from the Australian Dietary Guidelines for healthy eating.
Your score will be based on food variety, frequency, quantity and attributes like age and gender. You will receive a Diet Score between 1 and 100 and recommendations on how you can improve your diet.
The launch of the HDS follows more than three years of research by CSIRO and University of South Australia and is capable of providing a similar evaluation to other more complex diet assessment methods, such as weekly tracking of food intake
Research Director for Nutrition and Health and the co-author of the CSIRO Total Wellbeing Diet, Professor Manny Noakes, says that often most people overestimate how healthy their food intake is or may not be aware of what amounts of different foods are necessary for good nutrition.
“The online assessment aims to provide guidance on how to improve eating habits and to serve as a reminder that there is always room for improvement when it comes to making healthy food choices.
With most methods to assess eating habits being long and time consuming, we developed the Healthy Diet Score to provide an easy quick and reliable measurement for people to better understand the quality of their diet,” said Professor Noakes.
“A nutritious diet means eating a wide range of foods associated with a healthy lifestyle. However too often people will focus on a single food component or nutrient when looking to improve their diet. We know from previous research conducted that on average people are not eating enough vegetables, wholegrains and dairy foods and are eating too much junk food” said Professor Noakes.
You can watch Professor Noakes talking about the HDS on the Sunrise website.
We will aim to use the data collected from the HDS to help develop better ways to improve national eating habits and integrate it with other research into nutrition and dietary behaviour.
It only takes 10 minutes, so perhaps now’s the time to get your score?
Wouldn’t it be good if there were a spare ecosystem we could try things out on before making a decision about how we use resources? Sadly, there’s no Earth II, but at least we have Atlantis.
No, not the fabled sunken city, but a marine ecosystem modelling tool that lets resource managers and coastal planners test drive their decisions before they commit to them in the real world.
We’ve developed a model that encompasses oceanography, chemistry and biology, and simulates ecological processes such as consumption, migration, predation and mortality.
The United Nations rated Atlantis as the best ecosystem model in the world for looking at alternative management strategies for fisheries, and regional versions are being used in management strategy evaluation for more than 30 ecosystems in a wide range of places.
Before models like Atlantis were available, decisions about resource use were made in isolation. We’d make our plans about things like fisheries or water quality based on what we knew about fisheries or water quality, rather than on their effects on the entire system. And decisions like these – that don’t look at the system as a whole, interdependent web – can often be on the wrong side of the law of unintended consequences.
So Beth Fulton got to work and created Atlantis.
It gathers information including ocean currents, and the way the food system works, all the way up from phytoplankton – tiny plants that exist in oceans and underpin the marine food chain. They build up through to seaweed and sea grasses, different kinds of fish, to marine mammals like dugongs, sharks and seabirds. The modelling incorporates the ways people interact with the oceans and the Earth, and includes coastal industries such as ports and fisheries, along with the social and economic pressures that drive resource use decisions.
Atlantis has its longest usage history in south-eastern Australia. This is a marine area of about 4 million square kilometres, and home to Australia’s largest fishery. It’s also – literally – a hot spot for ocean warming. There the ocean temperature is rising faster than anywhere else, and the Australian current that extends down the eastern seaboard to Victoria is pushing further south to Tasmania.
The carbon dioxide that’s sucked up into the ocean is making the water more acidic. The balance of marine species, and their range, is likely to alter as the climate warms. We’ll still have fish and still be eating them, but there will need to be some major decisions made about how best to manage fisheries.
One of the beauties of the Atlantis model is that it can be re-calibrated with new data as the effects of warming oceans begin to be felt. This will be vital to making far-reaching decisions that can no longer be based on the old certainties.

How many insect specimens do you think are in the Australian National Insect Collection? A few hundred thousand? A million?
Actually, at the moment, it has about 12 million specimens, and it’s growing by about 100,000 a year. Like many natural history collections around the globe, the ANIC holds thousands of holotypes – each the single specimen of a species that is used to define its characteristic features.
There are all sorts of uses for these specimens, and a lot of people outside the world of entomology have very good reasons for looking at them very closely. But they’re fragile things, and many of them are tiny, so they can’t really leave their cases. And photographs don’t capture all the detail that’s sometimes needed.
So how to make the necessary information available to the people who can use it, while keeping the precious specimens safe and available for research work? Digital 3D colour modelling is ideal, but there have been some major barriers to doing that effectively. The system most used at present – Micro Computed Tomography (Micro CT) can create amazingly accurate models. But it doesn’t capture the object’s natural colour, which is vital information for species identification. It can take many hours. It’s X-ray based, so it needs special safety equipment. The machines also cost around $100,000, and they’re not portable.
Well, there had to be a better way, didn’t there?
So Matt Adcock and his colleagues did some lateral thinking, and came up with InsectScan 3D. This re-imagines 3D image-gathering in a way that doesn’t need custom-made or high-cost equipment (some of it actually came from the local hardware megastore), and the image is in full colour. The entire system uses standard components, and costs less than $8000 for the hardware and software. The digital 3D models come out in a file size small enough to be sent by email and used in web pages. And to make it even better, we can 3D print them.
The process uses multiple photographs of the subject, mounted on a disc marked with a pattern of dots. Using a standard DSLR camera and a 2-axis turntable, the insect is photographed at different angles and focus depths. These are then plotted by a computer, using the dot pattern to gauge the angle from which the picture was taken.
In some cases the 3D image is more useful than conventional microscopy. Obviously, the actual specimen provides all the information, but it has to be examined under a microscope for features like the mouth area and hair surface on the head. Out-of-focus effect and other physical restrictions makes using a microscope to view the actual specimen more difficult than viewing the 3D model.
The possibilities for this system are varied. Entomologists and taxonomists already have a massive backlog of insect types which have not yet been digitised in any form, and this system can provide what they’ve been asking for: a network of automated instruments that can clear the backlog by quickly and accurately creating 3D images of type specimens.
Schools and universities can use 3D models of insects as rich education materials, so students can interact with insects without endangering the fragile specimens.
But the most interesting use could be in quarantine and biosecurity. Invasive insects and the diseases they carry are an ever-present threat to Australia‘s environment, its agricultural industries and the health of the population. With this affordable, portable and accurate scanning technology, quarantine officers could carry a 3D gallery of invasive insects with them on inspections to help identify pests. Suspect specimens could be scanned in 3D and sent straight to an expert entomologist for examination. High resolution image libraries will mean we can quickly extract, analyse and share rich information, supporting biodiversity discovery, species identification, quarantine control, and unlocking the value of our biological collections.
Sounds pretty good, doesn’t it? This technology is a finalist in the Smart 100 innovation awards, and there’s a people’s choice category.

What came first – the chicken with the switched off allergen gene, or the allergy-free egg? Our scientists have been working with Deakin University to develop an egg that doesn’t cause allergic reactions, and it’s all about changing the chicken.
In a world first, the team has also created synthetic versions of all four egg white proteins in the lab.
Our own Dr Tim Doran, and Deakin University’s Associate Professor Cenk Suphioglu, said it was one of the first critical steps towards developing allergy-free eggs to make life easier for people with allergies and improve the safety of medications made with eggs, such as flu vaccines.
There are 40 proteins in egg white, but four major allergens that cause the majority of reactions.
Almost 9 per cent of Victorian infants have an egg allergy at 12 months of age, which can lead to dermatitis, asthma, vomiting or gut irritation.
Dr Doran, who has a daughter with such an allergy, said they were used in such a wide range of foods and products, including cosmetics and medication.
Associate Professor Suphioglu said they created all four versions of egg white proteins in the lab and switched off the allergenic response in one protein, which is responsible for the majority of allergies.
“We have developed the synthetic versions of the allergens, which are more pure and standardised than the natural extract, which would be useful for both skin-prick testing and immunotherapy,” he said.
Immunotherapy aims to give people tiny amounts of the allergen in a controlled medical setting to induce desensitisation or tolerance.
The advantage of switching off the allergenic part of the egg white protein would be that the patient would be less likely to have a dangerous allergic reaction during treatment.
Together with PhD candidate Pathum Dhanapala, the scientist’s ultimate aim is to modify the proteins in egg whites to produce chickens that lay allergy-free eggs.
Professor Mimi Tang, from the Murdoch Childrens Research Institute and Royal Children’s Hospital, said the synthetic protein could one day be useful in immunotherapy trials for allergies, but it was very early to be talking about clinical applications of the research.
“I think the major barriers to overcome with this product for it to be useful is to determine if it can be used to modulate immune responses and induce desensitisation or tolerance,” Prof Tang said.
The research is published in the journal Molecular Immunology.
So there you are, trying to take some pictures of the Aurora Australis, and there’s too much light. When there shouldn’t be. Blue light.
If you jumped to the conclusion that this was an alien invasion, you probably like science fiction. You’d also be right. But the aliens are from Earth, appearing in a place they don’t belong. However, they’re happily making it their home. Jellyfish expert Lisa-Anne Gershwin was in the right place at the right time to identify what was happening.
It’s a dinoflagellate called Noctiluca scintillans (which actually means ‘sparkling night’ in Latin). They’re phytoplankton – single-celled creatures, not strictly an animal, not exactly a plant. Seen separately, they look like tiny colourless lily-pads. But when the conditions are right, they look like something else altogether. Sometimes they bloom – countless tiny creatures, all massed together.
This was what the Aurora Australis photographers saw. All it takes is a good rain, which washes nutrients into the coastal water, combined with a gentle wind to concentrate these tiny creatures into a mass.
These blooms are almost certainly more common than we know, but most go unnoticed because they occur away from places where humans are likely to see them.
They make their own light, using a chemical reaction. Bioluminescence is found in almost every phylum, with different sorts of creatures having different colours of light, and using it for different purposes. It can be a startling effect to would-be predators, a warning to others, a call for help, or a way to recognise a potential mate. In this particular case it’s probably a startling effect, simply because the other explanations indicate greater cognitive function than is likely in single-celled creatures.
At South Arm in Tasmania, where a recent bloom occurred, the beach was blue for kilometres in both directions, glowing and flashing for most of the night. A band 1-2m wide along the beach was glowing quite brightly, and with each lapping wavelet it flashed a brilliant blue. The wave wash on the sand left behind a bed of twinkles.
Dipping your hand in it gave the skin an eerie Avatar-like appearance. A handful of sand thrown into the water elicited a brilliant flash of dots. And a piece of seaweed dipped into the water then flicked produced an amazing arc of light followed by an explosion of light when they hit the water. A kick of the water gave a similar arc and explosion, but even more brightly.
Sounds beautiful, doesn’t it? And it was, except here comes the ‘but’.
They’re an introduced species, penetrating the Southern Ocean, and they’re notorious for fish kills.
The majority of dinoflagellates are more plant-like than animal-like: they photosynthesise. Noctiluca doesn’t. Because it has no chloroplasts, it has to get food the old fashioned way, by eating something else. Mainly the ‘something else’ is other phytoplankton, but has been known to eat copepods (small crustaceans) and even occasionally tiny fish fry. Adjusted for scale, this is the equivalent of a human being eaten by a clam.
It’s been implicated in the decline of fisheries in other areas. Although it does not appear to be toxic itself, it accumulates and excretes high levels of ammonia into the surrounding area while it’s gorging itself on phytoplankton.
