Smart Grids and The New Age of Energy   Smart grid requirements: Network planning Power electronics (HVDC/FACTS) Bulk renewable integration Energy Management System (EMS) Smart substation automation and protection Integrated Substation Condition Monitoring (ISCM) Communication Solutions Distribution Management System (DMS) Distribution automation and protection Distributed Energy Resources (DER) Decentralized Energy Management System (DEMS) Smart metering solutions Conclusion.                        1. Network planning Smart grid - A vision for the future, a network of integrated microgrids that can monitor and heal itself Building Smart Grids is a highly complex task that begins with a detailed quantitative assessment of the system requirements , definition of actual targets and their required performance levels, and specification of system concepts and equipment. As a result, a comprehensive strategy for building Smart Grids is necessary – i

Energy Harvesting ‘Piezo-tree’ Concept. As the leaves move in the wind energy is generated, this is then converted into electric energy. The flapping motion of the leaves is attributed to instability of the aero-elastic system. The “Piezo-tree” has been made using flexible piezoelectric material Polyvinylidene Fluoride (PVDF).     The device is able to convert the energy in wind into electric power whilst remaining light, low-cost, and easily scaled.   In the prototype, the flexible plate and film are driven to oscillate just as a flag or leaf might flap in the wind. The flapping motion is attributed to instability of the aero-elastic system. When creating the piezo-tree, researches used the flexible piezoelectric material Polyvinylidene Fluoride (PVDF) as the basic component, as it could withstand unpredictable wind strength. The basic design is to clamp one edge of PVDF element to a cylinder bluff body and leave the other edge free. When the wind crosses this bluff body,

 Airbia lets suburban commuters fly high                                     Airbia is an amazing airship designed by Alexandros Tsolakis and Irene Shamma . It is possible that such eco-friendly airships will replace in the near future today's air-polluting means of transport . Airbia infrastructure system will make it possible for people to travel from suburban areas to urban city centers fast and easy. The airships use helium and with overhead loading platforms the system will require a rather small amount of infrastructure. It is worth mentioning that each airship will have the possibility to carry up to 400 people and the average speed of travel will reach 93 miles an hour (150km/h). Airbia airships will fly at heights that will range between 30 and 500 meters above the ground. According to Tsolakis and Shamma, their system could replace vehicles and trains as a mean of transportation that helps people get from suburbs to city centers. Airbia represents one of 20 a

Google's driverless car    Google's driverless car has been proven, and Google has already got the state's of California and Nevada on board with them. They are now working with officials in these districts to develop laws for the implementation of fully-autonomous vehicles. Google says that it now needs to move forward as fast as possible with this technology, which I believe can be decoded as: "All our competitors know as well as we do that driverless cars are the soon-to-be future, because we've shown that it can be done and that we will continue to develop this technology. And most importantly, the key political barriers have been removed" . [note: This paragraph is not a literal quote]. In other words the race is on. No-one informed on this issue is second-guessing whether driverless cars are the future now. Even politicians, world over and in New Zealand, are starting to talk seriously about it. Good! What driverless cars mean: Most people t
