The EcoDrain uses outgoing hot water to heat incoming cold water

Generally-speaking, when there's something that we're trying to conserve, we don't just put it down the drain. For those of us who are trying to save power, however, that's just what happens when we let hot water from our showers or baths run straight into the sewer. The EcoDrain is made to address that problem, via a unique design that allows outgoing hot water to warm up incoming cold water.  Read More

The Illawarra Flame house was created by students from the University of Wollongong

A group of students from the University of Wollongong took a typical Australian "fibro house," and retrofitted it with technology which includes solar panels, climate control, and an energy monitoring system. The end result, dubbed Illawarra Flame, is a net-zero home which offers a potential starting point for transforming many similar properties into low-energy dwellings.  Read More

A new lightweight hoisting line known as UltraRope could double the current maximum height...

As architects continue to design taller and taller buildings, a certain limitation of elevators is going to become more of a problem – using traditional steel lifting cables, they can’t go farther than 500 meters (1,640 ft) in one vertical run. Any higher, and the weight of all the cable required is simply too much. Currently in the world's few buildings that are over 500 meters tall, passengers must transfer from one elevator line to another, part way up. Thanks to a new lightweight material known as UltraRope, however, elevators should now be able to travel up to one kilometer (3,281 ft) continuously.  Read More

How do you measure the life of a light source that could last decades? (Photo: Shutterstoc...

Just over a week ago we reported that Philips' 22 W LED light bulb, designed as a like-for-like replacement of a 100-W incandescent light bulb, was the first LED bulb of its type to receive the stamp of approval from Energy Star. But looking at the Energy Star requirements reported by Philips in its press release, it seemed a little strange that Philips' product is the only one to have been certified – given that products long on the market appear, at face value, to meet those requirements. Since then, Gizmag has spoken to LED light bulb makers Switch Lighting and other industry players to find out why they're apparently playing catch-up.  Read More
