Wind Power for Electricity!   2 comments

This world is rapidly gaining its momentum and meaning of our basic needs growing exponentially over time. Without technology, no one can survive; in fact, people have been mechanized and it is the only one way door to breathe in changing world. In the run for Science & Technology adaptation in Nepal, the most remarkable first hydro-electricity generated was the 500kW turbine at Pharphing, built in 1911 to supply electricity to Kathmandu city. After almost a century of development in electricity generation; electrification was seen as a development tool which would bring social and environmental benefits to rural communities and to the nation as a whole. The pragmatic implication of electricity on a household basis would relief a woman’s heavy duty and physical workload pressure. Water, Water and Water everywhere virtually in Nepal and we are unable to scoop it for electricity from hydel (hydroelectricity).

It is absolutely a grim situation of Nepal that two days back; the NEA (Nepal Electricity Authority) announced eight hours of ‘load shedding’ where various industries are shutting down. On the other hand, in the name of environment preservation, we still are depending upon hydel where our neighboring countries like India are increasing the number of other alternatives like Nuclear Power Plant and Wind Power for perpetual flow of electricity.Nepalhas no exploitable fossil fuel resources and dependence on imports has become both a strain on the economy and a point of vulnerability, as the trade dispute with Indian in 1989 revealed. Ever since then, the government of Nepal has given energy supply a high priority in its plans for the country’s development, and, since the oil crisis in the 1970s, has shown increasing interest in and support for hydroelectricity as an energy source. Should we still live in the dark or augment our nations with advancement in Science & Technology? The choices are in our hand? Else, the water resources should be exploited enough to flow electricity perpetually around Nepal meeting the increasing demand no matter it is the most remote village.

Our neighbor India has a space satellite and nuclear industries which led us to ponder their capacity in Science & Technology where our nation is still following conventional hydel system and have become a perfect parasite for fossil fuel products. Now, it’s a time to generate our own independent system in electricity. The government should invest 50 paisa a liter of gasoline utilization for green and clean energy resources research & development that self sustains Nepal. Power generation from wind has emerged as one of the most successful programmes in the renewable energy sector, and has started making meaningful contributions to the overall power requirements of some States.

Renewable energy produced from the wind has garnered much attention and support in recent years but is often criticized for its low output and lack of reliability. But now a super power wind turbine has come along that may be just what the renewable energy industry needs. The MagLev wind turbine, which was first unveiled at the Wind Power Asia exhibition in Beijing, is expected take wind power technology to the next level with magnetic levitation. Magnetic levitation is an extremely efficient system for wind energy. Here’s how it works: the vertically oriented blades of the wind turbine are suspended in the air above the base of the machine, replacing the need for ball bearings. The turbine uses “full-permanent” magnets, not electromagnets — therefore, it does not require electricity to run. The full-permanent magnet system employs neodymium (”rare earth”) magnets and there is no energy loss through friction. This also helps reduce maintenance costs and increases the lifespan of the generator.

Maglev wind turbines have several advantages over conventional wind turbines. For instance, they’re able to use winds with starting speeds as low as 1.5 meters per second (m/s). Also, they could operate in winds exceeding 40 m/s. Currently, the largest conventional wind turbines in the world produce only five megawatts of power. However, one large maglev wind turbine could generate one gigawatt of clean power, enough to supply energy to 750,000 homes. It would also increase generation capacity by 20% over conventional wind turbines and decrease operational costs by 50%. If that isn’t enough, the maglev wind turbines will be operational for about 500 years! Construction began on the world’s largest production site for maglev wind turbines in central China on November 5, 2007.


Zhongke Hengyuan Energy Technology has invested 400 million yuan in building this facility, which will produce maglev wind turbines with capacities ranging from 400 to 5,000 Watts. In the US, Arizona-based MagLev Wind Turbine Technologies will be manufacturing these turbines. Headed by long-time renewable energy researcher Ed Mazur, the company claims that it will be able to deliver clean power for less than one cent per kilowatt hour with this new technology. It also points out that building a single giant maglev wind turbine would reduce construction and maintenance costs and require much less land than hundreds of conventional turbines.

Establishment of such technology will definitely reduce the natural resource consumption. Therefore, maglev wind turbine is so far the best option to Nepal. Even if, Nepal seeks technology-transfer; an endeavor should be the renewable resources adaptation methodology with continuation in Research & Development for greener and cleaner utilities in Nepal. Shall we start?
