The Download: AI “mind-reading” and creative uses for small batteries

This edition of The Download explores fascinating advancements in artificial intelligence and battery technology. A groundbreaking AI tool is able to "mind-read" by analyzing brain scans and reconstructing images or predicting brain activity based on what a person is looking at. Researchers hope this mind-reading tool could provide valuable insights into brain function, assist locked-in individuals in communication, and potentially even recreate the content of dreams.

However, experts warn that such technology could also be misused to reveal people's inner thoughts and mental imagery without their consent.

Meanwhile, the quest for smaller, more distributed batteries is gaining traction as traditional large-scale battery installations face opposition in densely populated areas due to fire risks. Startups are innovating by using compact batteries in unexpected applications, such as induction stovetops and food carts, to help consumers cut pollution and power bills. As these small batteries become more prevalent, they could collectively contribute to a significant increase in energy storage capacity.
