#RoadsThatHonk works by alerting speeding drivers to avoid collisions with the help of SmartLife poles that use radar technology across accident prone turns. The poles are installed at key intersections, and use an advanced networked device to combine wireless technology, radar systems, and an anti-collision warning system, all powered by solar PV modules. http://www.thedrum.com/news/2017/04/27/hp-and-leo-burnett-collaborate-anti-collision-tech-roadsthathonk-campaign

IIT Madras students have developed a house than can be folded up and transported anywhere. It's a two-storey house made out of metal frames and iron panels that can be unfolded and fixed to accommodate 20 people at a time. It can be set anywhere that's flat; all you have to do is unfold its metal frames and start fixing the panels which will be the walls for the house. There are provisions for electricity and water supply as well. This construction should be especially useful when natural disasters render many homeless.
