Comments Off on Tesla just unveiled the world’s largest battery storage plant

Tesla just completed construction on what it claims is the largest lithium-ion battery storage project in the world. The facility is located at in Ontario, California and it consists of 396 Tesla powerpacks that can store 80 megawatt-hours of electricity – that’s enough to power over 2,500 households for a day or 15,000 households for four hours. Tesla nabbed the contract to build the battery storage facility for Southern California Edison in September 2016, and it was completed by the end of that year. The project consists of two 10 megawatt systems – each made of 198 Tesla Powerpacks and 24 inverters – connected to two different circuits at the Mira Loma Substation. Tesla Chief Technical Officer JB Straubel said “Storage is quite a new thing…and this is a different breed of battery. This is the tip of the iceberg of how much storage we’ll see on the grid .” Related: Solar homes with Tesla’s Powerwall 2.0 are already cost-competitive with the grid in Australia SCE said the facility would allow them to draw more on clean energies like solar power . When clean energy projects produce more electricity than the utility needs, it can now be stores and utilized during peak hours. The Tesla battery storage facility seems like the perfect answer to our energy issues, but MIT Technology Review points out lithium batteries are still expensive, and no one has said how much the facility cost. It’s also not clear how many cycles the Powerpack batteries can go through before they begin to degrade – MIT estimates 5,000 cycles, which would work well in a home but not as well in a grid setting. At the ribbon-cutting, SCE CEO Kevin Payne said, “This project is part of our vision at SCE to take advantage of the wind and the sun, and operate a flexible grid that delivers clean energy to power our homes, our businesses, and our vehicles. Standing here today among these Tesla Powerpacks is a great reminder of how fast technology is changing the electric power industry and the opportunities that will come with it.” Via MIT Technology Review Images via Ernesto Sanchez/Edison International

These new devices generate renewable energy from evaporation

Comments Off on These new devices generate renewable energy from evaporation

Click here to view the embedded video. Evaporation is a key component of the Earth’s water cycle, and one of the world’s most dominant forms of energy transfer—and it’s believed that as the climate warms, evaporation rates will increase and result in more moisture in the lower atmosphere. Yet the power of evaporation has rarely, if ever, been utilized for energy generation. But one lab at Columbia University is seeking to change that. By harnessing the natural properties of spores—and their responses to humidity—they have created two devices that generate renewable energy from evaporation , and the lab hopes that one day these devices could be scaled up to produce electricity from large floating power generators, or from rotating machines akin to wind turbines that sit above water.

Generador eolico: A vertical axis wind turbine system for greater efficiency

Comments Off on Generador eolico: A vertical axis wind turbine system for greater efficiency

DATTATREYA MANDAL: Generador eolico Designed by Miriam Petersen Statistically, power consumption from ‘clean and green’ wind has reached an all time high (almost 2.5 percent of worldwide electricity usage), with a whopping 197 GW nameplate capacity and 430 TWh of total energy production. And, with this righteous trend of large scale commercialization of wind power, small scale wind generators for micro-level usage are certainly becoming all the more important. Taking into account of this inherent flexibility, Argentine designer Miriam Peterson has conceptualized the effective Generador Eolico – a domestic vertical axis wind turbine system based on Savonius rotors. Picture Gallery Wind turbine – Generador eolico Wind turbine by Miriam Petersen Savonius rotors can utilize the force of the wind and convert it into a torque on a rotating shaft. In this system, three separately intricate Savonius rotors (connected to respective generators) will be fixed by sturdy cables to a central module. The central module in turn will be connected to a storing point with an integrated 12V, 220A battery pack. The basic design alludes to the intrinsic aerodynamic property of the rotors in their multiple forms, which will augment the magnitude of wind energy that is to be transformed into clean electricity. According to the designer, the generator can harness the wind at a paltry 4m/s, as this instills a whopping 50 rpm in the efficient rotors. The total output capacity of the setup can be marked at 3 KW. But the predicament lies with the safety factor, especially when high speed rotating blades are placed in a domestic environment. Hence, the designer has also adroitly thought of horizontally placed security wheels that can warn users by their conspicuous rotation. Moreover, with their perforations, the total lateral drag is cut down, thus accentuating upon the overall lightness of the mechanism. Via: Coroflot
