Support strut probably caused failure

Makes Statement

Musk says a support strut holding one of the helium tanks likely fractured near a bolt attach point, and wanted to move to the top of the Falcon 9’s second stage. Several helium tanks, each pressurized to about 5,500 pounds per square inch, are mounted inside the rocket’s second stage liquid oxygen tank. The helium is routed through the second stage’s Merlin engine, where the helium warms up and injected into the rocket’s propellant tanks to pressurize the stage as the launcher burns fuel, keeping the tanks structurally sound. Musk:

It may seem sort of counterintuitive that, as the rocket’s accelerating, that something immersed in the tank would actually want to go up more, but that’s basically what happened. The buoyancy increases proportionate to the G-loading. At approximately 3.2 Gs, this strut holding down one of the helium bottles appears to have snapped, and as a result, releasing a lot of helium into the upper stage oxygen tank and causing an over-pressure event quite quickly…Within the course of a second, this caused enough helium to be released, we believe, to over-pressurize the liquid oxygen tank in the upper stage. You don’t really need to release a lot of helium because there’s only about 2 percent gaseous volume in the stage because the upper stage propellant is not being consumed.

Reveals timeline for Model 3

Makes Statement

in an earnings call Musk reveals a tentative schedule for the Model 3, which is expected to cost $35,000 before government subsidies, saying the company plans to unveil the model in March 2016, and a sale date of mid 2017, but probably later.

I mean, we are hoping to show off the Model 3 in approximately March of next year. Again, like, don’t hold me to that month, but that’s, like — that’s our aspiration.

Adds battery into DemandLogic system

Makes Statement

SolarCity incorporates the Tesla battery into its DemandLogic energy storage system to increase the utility cost savings customers can realize from using stored solar electricity. DemandLogic, which is being adopted by several of the largest retail, biotech and Internet companies in the U.S., allows businesses to reduce energy costs by using stored electricity to reduce peak demand, and can also provide backup power during grid outages. DemandLogic’s management software automates the discharge of stored energy to optimize savings on utility demand charges for customers.
