TOP 2 INVENTION OF THE MONTH----
1- Charged In 30 Seconds: High school student Eesha Khare created a new kind of super-capacitor energy-storing device that could eventually lead to superfast battery charging for phones and other devices (including car batteries). Khare’s device (which netted her a $50,000 scholarship from the Intel International Science and Engineering Fair) has a special nanostructure that makes it last longer than the average battery and charge up quicker -- though at present, it stores less energy than a comparable battery. But the Harvard-bound teen will have plenty of time to perfect her invention in the years ahead.
2- Bladeless Windmill: Wind power without spinning blades? Impossible, you might say -- but you’d be wrong. The Dutch architecture firm Mecanoo installed this powerful, curious-looking contraption at the Delft University of Technology in March. Instead of translating the mechanical energy derived from the movement of large blades rotated by the wind, the bladeless turbine lets wind move electrically charged water droplets against the direction of an electric field, increasing the potential energy of the particle. A collecting system then harvests that excess energy. The lack of large moving parts means the turbine is quieter and creates much less vibration, making it much better-suited to urban envir
