1414 Degrees has developed storage technology using the latent energy characteristics of molten silicon which is scalable from a few megawatt hours to many hundreds of megawatt hours, is site agnostic, has no operational fuel costs, is environmentally benign during it's 25 year operating life cycle and has no environmental impact on decommissioning. The prototype plant has been running since September 2016 at the Tonsley Park Innovation Precinct in South Australia and the first commercial model will be installed in 2017. Power networks the world over can only fully rely on renewables generation when there is reliable, scalable and readily accessible energy storage available. http://1414degrees.com.au/

This lifesaving ring can be controlled by a lifeguard using a radio controller. The idea is to help make the rescue operation swifter and lessen the stress of the person in the water.?http://www.yankodesign.com/2011/11/29/radio-controlled-lifesavers/

My idea is about sharing electricity by Bluetooth. Bluetooth can wirelessly transmit relatively small amounts of data over a short range (<100m). Its networks use a master/slave model to control when and where devices can send data. What if these networks could also send electricity? A startup called Energous has been working on this. https://www.google.com.au/amp/www.theverge.com/platform/amp/2017/1/4/14124938/energous-truly-wireless-charging-apple-ces-2017

Volkerwessels say that their plastic road has a lightweight design, a fraction of the construction time, is virtually maintenance free, and has three times the expected lifespan. It consists of 100% recycled material which makes it a sustainable alternative to conventional road structures. https://en.volkerwessels.com/en/projects/detail/plasticroad
