The Bay Area's SkyCool Systems is developing a technology that one day might be used to significantly cut energy demands from air conditioning, one of the U.S.'s major draws of electricity, per MIT Technology Review.

  • How it works: SkyCool has developed panels that reflect sunlight at a specific infrared range that allows heat to slip through the atmosphere, allowing their surface to cool — while also cooling the water used in traditional air conditioning systems. Recent results suggest existing buildings can be retrofitted with the technology.
  • By the numbers: The panels could cut energy use in buildings by 10 to 70%, depending on conditions.
  • Why it matters: Should SkyCool's proof-of-concept test pan out (they're currently in field trials), the technology could have a serious impact at hotels, supermarkets and other places that require massive amounts of climate control.

Trump tightens screws on ByteDance to sell Tiktok

President Trump added more pressure Friday night on China-based TikTok parent ByteDance to exit the U.S., ordering it to divest all assets related to the U.S. operation of TikTok within 90 days.

Between the lines: The order means ByteDance must be wholly disentangled from TikTok in the U.S. by November. Trump had previously ordered TikTok banned if ByteDance hadn't struck a deal within 45 days. The new order likely means ByteDance has just another 45 days after that to fully close the deal, one White House source told Axios.

In her first sit-down interview since being named Joe Biden's running mate, Sen. Kamala Harris talked about what she'll do to fight for women if elected VP, and how the Democrats are thinking about voter turnout strategies ahead of November.

What they're saying: "In a Biden-Harris administration women are going to be a priority, understanding that women have many priorities and all of them must be acknowledged," Harris told The 19th*'s Errin Haines-Whack.
