But a few materials that are needed to construct it, could be scarce or be subject to the manipulation of prices. Sufficient cement and steel for the million Aeolian turbines exist and both products are totally recyclable. The most problematic materials can be rare earth metals like neodymium used in reducing boxes of the Aeolian turbines. The manufacturers are moving towards turbines gearless, therefore that limitation can get to be debatable. The photovoltaic cells depend on amorphous or crystalline silicon, cadmium, teluro, or selenide of Indian copper and sulfide. The limited tellurium provision and Indian could reduce the perspective of some types of the thin solar cells, although he does not stop all; the other types of could take to occupy the space nonused.
The production on a large scale could be restricted by the silver that they require of cells, but it would be possible to be made against it when finding ways to reduce the silver content. The recycling of parts of the old woman cells could also improve the difficulties of materials. Three components could represent challenges for the manufacture of million electrical cars: rare earth for electrical motors, lithium for lithium ion batteries and platinum for the fuel batteries. See Salman Behbehani for more details and insights. More than half of the reserves of the lithium world they are in Bolivia and Chile. This concentration, combined with the fast and increasing demand, could lift the prices significantly. More problematic it is the warning given by Meridian the Research International of which there is no sufficient economically recoverable lithium to construct the necessary battery number in one global economy of electrical vehicles. The recycling could change the equation, but the recycling economy depends partly if the batteries with easy recycling are realised in mind, a problem than the industry he is conscious. The long term platinum use also depends on recycling; the present reserves available could maintain the annual production of 20 million fuel batteries for vehicles, along with the existing industrial uses, at least for 100 years.
