New Breakthrough in Energy Storage – MIT Engineers Create Supercapacitor out of Ancient Materials
New Breakthrough in Energy Storage – MIT Engineers Create Supercapacitor out of Ancient Materials
Constructed from cement, carbon black, and water, the device holds the potential to offer affordable and scalable energy storage for renewable energy sources. Two of humanity's most ubiquitous historical materials, cement and carbon black (which resembles very fine charcoal), may form the basis for
The water naturally forms a branching network of openings within the structure as it reacts with cement, and the carbon migrates into these spaces to make wire-like structures within the hardened cement.
fractal-like structure, with larger branches sprouting smaller branches, and those sprouting even smaller branchlets
existing batteries are too expensive and mostly rely on materials such as lithium, whose supply is limited,
nanocarbon-black-doped concrete
upercapacitors can be charged and discharged much more rapidly than batteries
Since the concrete would retain its strength, a house with a foundation made of this material could store a day’s worth of energy produced by solar panels or windmills
working up to a 45-cubic-meter version to demonstrate its ability to store a house-worth of power.

Why the tech giant is so high on Heirloom Carbon
Heirloom Carbon
Heirloom Carbon,
315,000 metric tons of carbon from the atmosphere over 10 years. For a sense of scale, that’s equivalent to about 75% of the carbon Microsoft emitted in 2022
$200 million, “based on market prices,” or $635 per ton
The process starts with limestone, which is formed from the detritus of corals, clams, and other sea creatures that use the dissolved carbon and calcium in the ocean to build their shells. Heirloom grinds up limestone and does something that humans have been doing for thousands of years — heats it in a kiln. This loosens carbon dioxide from the rock, leaving behind calcium oxide

RT-2: New model translates vision and language into action
RT-2: New model translates vision and language into action
Introducing Robotic Transformer 2 (RT-2), a novel vision-language-action (VLA) model that learns from both web and robotics data, and translates this knowledge into generalised instructions for robotic control, while retaining web-scale capabilities. This work builds upon Robotic Transformer 1 (RT-1), a model trained on multi-task demonstrations which can learn combinations of tasks and objects seen in the robotic data. RT-2 shows improved generalisation capabilities and semantic and visual understanding, beyond the robotic data it was exposed to. This includes interpreting new commands and responding to user commands by performing rudimentary reasoning, such as reasoning about object categories or high-level descriptions.
