Last year when I went to Disney, I had asked one of the cast members there and she said that she really wasnt sure but she thought there had to be over 50,000 people who work for disney. Walt Disney World Employees.
Methane is just used as a fuel for a gas turbine (can also be used to drive an internal combustion engine coupled to a generator). The turbine is coupled to a generator, which generates electricity.
Turbines will be used to force air which is heated by the sun through a 2,600 foot chimney in order to generate huge amounts of natural power. It is estimated that more than one million megawatt hours will be produced by the huge building, providing enough electricity to power 150,000 homes.
