Ten years ago, Musk wrote
about the «
secret master plan» for Tesla, which began with building a low - volume expensive
electric car, then using the profits from that to develop a medium - volume EV at a lower price, using the money from that
car to create «an affordable, high volume
car,» and to then «provide zero emission
electric power generation options» (solar).
The patent makes its statements in broad terms, speaking generally
about any portable device and vehicle, but of course the idea has direct application to Apple's
electric car project, which is an «open
secret,» according to Tesla founder Elon Musk.
