Last night, on a back lot at Universal Studios, Tesla unveiled the most promising facet of its impending merger with SolarCity — solar shingles as chic and efficient as their cars. These were paired with new Powerwall home batteries that have double the energy density of Tesla’s first Powerwall product. You can watch the full video of the presentation in Steve’s article or further down in this on. The event was primarily for Tesla owners, so it took me longer to get up the hill from the studio gate than it did to ride my Zero from Vernon at rush hour. But I did get to hitch a ride in a swanky Model X, which was a lovely way to start the Tesla world experience.
