We all know we should turn off appliances at the wall to reduce fire risk as well as our carbon emissions, but the truth is most of us can't be bothered or think to flick the switch. The eco-switch could be the answer: it’s a simple and inexpensive energy-saving device that lets you relocate the power point switch to a more convenient spot where you can turn multiple appliances on and off – with the flick of a single switch.  Read More

The Solaqua uses UV and infrared rays from the sun to kill pathogens in contaminated water

Eye-drops may be a simple way of medicating the eye, but patients don't always get the right dose at the right time. Eyenovations has developed contact lenses that can deliver drugs to the eye in measured doses for a month or longer. The start-up company’s initial focus is developing a lens to help glaucoma patients. However, it believes the technology can be used to help other eye conditions and deliver antibiotics following surgery.  Read More

Australia’s ‘Black Saturday’ in February claimed 173 lives and countless homes and livelihoods. The country’s worst wildfire tragedy, this horrific disaster was an extreme example of an annual threat faced not only in Australia but also North America and South Africa where similar dry conditions are experienced. As the survivors struggle to come to terms with their losses and begin to rebuild their lives, questions are being asked about what could have been done, and what must be done now to better protect populations. Tougher building standards for homes in fire-prone areas will be introduced, but another option under scrutiny is fire resistant shelters - are they safe, should governments play a role in their development and how should they be designed and built? Entering this debate is the Bushbunker, a dedicated fire shelter design which aims to maximize the likelihood of survival regardless of the intensity or type of fire.  Read More
