Nearly two years comfort north builds a lot of fan in slippery county cornfield, campagna region sees rarely previously, still go before a few years on the road of Xinjiang, build on the desert beach of Gansu Province have a lot of fan. Fan is 120 meters tall, every wind leaf is as long as 50 metersThis is to be in construction advocate tower, wind-force generates electricity is to show the kinetic energy that keep watch turns for electric energy. Wind energy is a kind of cleanness do not have social effects of pollution but energy resources of second birth energy, early is used by people, basically be to pass the windmill to come pump water, grind a face wait, and now, what people is interested is how to use wind to generate electricity. | | | Use wind-force to generate electricity special environmental protection, and wind energy accumulate the amount is huge, clean environmental protectionLofty tower crane is assembling the part of fanThis is fan coping, secure the base of fan leafThe child is curious very, ask for those who get worker master worker to agree, look after children go fan interior looks after allThis is fan interior construction, the engineer is debugging equipmentThis worker master worker says, the telegram that the fan here sends, arrived directly national electrified wire netting, did not turn circuit, can send probably for two times report, but of fan make cost very tall, one needs probably 15 million the left and right sides, after building, if investment is used, subtract every year artificial and safeguard of fan daily, time also get 3 years originally, but after cost calls in, gain is very sizable, the service life of a fan is in 50 years of aboveThis is huge base, before the ground, it is a large hole, it is the concrete that is basket of reinforcing steel bar and high grade completely is cast inside rise, the expenditure of a foundation is in a hundred or so 10 thousand above
