At 14:23 Lars explained that they said in the Tesla quarterly report that the nuclear power plant including the safety zone land around it is big enough to hold a solar plant that will generate the same amount of power. So why not build solar farms instead of nuclear power plants? This brings to mind the SONGS – San Onofre Nuclear Generating Station in So. California that is now being decommissioned. SCE et. al. should build a solar farm on the land.
At 12:55 Lars showed a photograph of the inside of Gigafactory Texas, with all the robotic arms being installed. The walls (green in the background) are being installed, so soon the insides will no longer be visible to the drones flying outside.
