Tesla PowerWall & Gigafactory

從幾個數字看中國2015年預計装17.8Gega 

Tesla 目前在蓋一個用太陽能及風能力自己足的35Gega W 工廠 (2020)。
1)比現金全球鋰電池廠加起來還大
2)鑽石形狀,充分利用地形,設備GPS
安装
3)近日開啟家用電池市場, Tesla Power Wall,10MW只要USD3500. 
解决石化燃料污染及長遠短缺(提及太陽是每日及週而復始可用而且最潔淨)
另外解決傳統電池大不美觀問題。

此一夢想太大,但是Elon已經開啟先河。

Tesla Gigafactory

Tesla’s mission is to accelerate the world’s transition to sustainable transportation. To achieve that goal, we must produce electric vehicles in sufficient volume to force change in the automobile industry. With a planned production rate of 500,000 cars per year in the latter half of this decade, Tesla alone will require today’s entire worldwide production of lithium ion batteries. The Tesla Gigafactory was born of necessity and will supply enough batteries to support our projected vehicle demand.

Tesla broke ground on the Gigafactory in June 2014 outside Sparks, Nevada, and we expect to begin cell production in 2017. By 2020, the Gigafactory will reach full capacity and produce more lithium ion batteries annually than were produced worldwide in 2013.

In cooperation with Panasonic and other strategic partners, the Gigafactory will produce batteries for significantly less cost using economies of scale, innovative manufacturing, reduction of waste, and the simple optimization of locating most manufacturing process under one roof. We expect to drive down the per kilowatt hour (kWh) cost of our battery pack by more than 30 percent. The Gigafactory will also be powered by renewable energy sources, with the goal of achieving net zero energy.

The name Gigafactory comes from the factory’s planned annual battery production capacity of 35 gigawatt-hours (GWh). “Giga” is a unit of measurement that represents “billions”. One GWh is the equivalent of generating (or consuming) one billion watts for one hour—one million times that of one kWh.
