[ { "role": "user", "content": "The Cube is the world's first carbon concrete building. Its concrete is reinforced with carbon fibers rather than steel rods, making it four times stronger and lighter than traditional concrete. As carbon fiber doesn't rust, the concrete is more durable over a longer period. It also allows for the same structural strength while using far less material. Carbon concrete can reduce CO2 emissions from construction by up to 50 percent. A video outlining the construction process of The Cube is available in the article." }, { "role": "assistant", "content": "The World's First Carbon Concrete Building Is Under Construction" } ]

It only had a brief mention during the presentations where Musk described it as a super-powerful training computer that will be able to take in vast amounts of data and complete massive amounts of video training unsupervised. Current machine learning systems process videos frame by frame, but Dojo may be able to handle videos on its own.

Enamel was grown from a gel that was made from calcium and phosphate ions mixed with trimethylamine.
