The Download: deep diving, and virtual power plants in China

Feb 21, 2024 - technologyreview.com
The article discusses various technological advancements and issues, including the exploration of the deepest underwater caves by divers Richard “Harry” Harris and Craig Challen, who are testing the potential of breathing hydrogen to reach depths beyond 310 meters. It also mentions China's ambitious electric vehicle (EV) plans that involve the use of virtual power plants (VPPs) to manage energy consumption and supply, and the country's testing of programs incentivizing EV owners to charge their vehicles during off-peak hours.

The article also highlights the open-source AI boom, which is seen as a threat to Big Tech's dominance in AI, as smaller, cheaper versions of top AI models are being shared for free. However, the sustainability of this open-source boom is uncertain. Other topics covered include Alabama's Supreme Court ruling on frozen embryos, the EU's rules for carbon removal technologies, the use of mind-reading devices, and the proliferation of fake funeral livestream scams on Facebook.

Key takeaways:

  • Divers Richard “Harry” Harris and Craig Challen are exploring the limits of human diving depth, testing the use of hydrogen for breathing at depths beyond 310 meters.
  • China is leveraging Virtual Power Plants (VPPs) to manage energy consumption and supply, particularly in relation to the growing use of electric vehicles.
  • The open-source AI boom, with smaller, cheaper versions of AI models being shared for free, is seen as a threat to Big Tech's dominance in the field.
  • Researchers are exploring the use of mind-reading devices to restore functions like speech and movement, and to gain insights into how the brain works.
