#4 Memristors will drastically change the world of electrical engineering

Sure the transistors, replacing big vacuum tubes, made the sleek gadgets what we hold in our hands possible. Imagine a new technology called memristors, a new electric circuit component that takes its name from "memory" and "resistor," can do to the gadgets. Hewlett-Packard is already doing big work in this space. HP Labs Fellow R. Stanley Williams said, "The memristor holds its memory longer. It’s simpler. It’s easier to make — which means it’s cheaper — and it can be switched a lot faster, with less energy.”

#3 Nanofiber salt filters could be used to harvest ocean water for drinking

Though 71 percent of earth is water in which 97.5 percent is contained within the oceans, while the remaining 2.5 percent is freshwater. Which means the world is most desperate for clean drinking water. The new technology called as Nanofiber, a fibrous material that's incredibly thin, can function very effectively as a salt filter since individual grains of salt are too big to pass through the holes in the nanofiber, turning salty water to drinking.
