While building additional lines and power generation units to solve access to electricity, the values of reliability and efficiency are normally not on the top of mind for system planning. What if access to electricity is provided by renewable microgrids, would values like reliability and energy efficiency be achieved at the same time? Sigue leyendo →
The concept of the GravityLight is simple and yet very innovative. It consists in a light powered by gravity, it is charged by lifting a weight and letting its descent run the generator and the light.
Of course, it is only possible now thanks to the LED lights and other efficiency gains. With old light bulbs, the duration of the same concept would be ridicule, but now, a simple lift of 2-3 seconds can provide for almost 30 minutes of light.
