The Bushbunker: last resort wildfire protection

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

Smarter wind technology looks to improve turbine workrate

Clean, renewable energy is freely available – in the form of wind, sun and water. However, harnessing it reliably and cost-effectively remains a barrier. Wind power is one of the fastest growing alternative energy markets and researchers at Purdue University and Sandia National Laboratories in West Lafayette, Indiana, are working to make wind turbines more efficient, reliable and resilient.

Orbita Sparta Mini watchwinder - one for the ladies?

As the name suggests, automatic or self-winding watches wind themselves using a moving weight mechanism inside the watch. All well and good if you are wearing your watch everyday, but if you happen to have a collection, you'll often find yourself faced with the fiddly task of manual winding and resetting features like perpetual calendars - a difficult job for large unwieldy fingers (men) and delicate fingernails (women) - which is where watchwinders come in. This one, the Sparta Mini from Orbita, is for the ladies.Read More

The CellScope: transforming the cell phone into a mobile microscope

The CellScope is a revolutionary attachment that turns a standard camera-enabled cell phone into a clinical quality microscope, with magnification up to 50X. Health workers in developing countries, where expensive equipment, facilities and on-the-ground physicians are scarce, will be able to use the mobile microscope to quickly and easily capture images of blood cells, lesions and infections and transmit them via the cell phone network to remote experts for analysis and diagnosis.Read More
