Notes Today: 

  • The world’s largest battery manufacturer CATL has announced a new “condensed” battery with 500 Wh/kg which it says will go into mass production this year." Batteries with 400 Wh/kg energy density  could enable competitive commercial airplanes. 

  • China raised its gold holdings by about 8.09 tons in April, according to data from the State Administration of Foreign Exchange on Sunday. Total stockpiles now sit at about 2,076 tons, after the nation increased reserves by about 120 tons in the five months through March.
  • The U.S. self-reported rate of mental health distress is similar to Canada’s (27%) and Sweden’s (24%). And yet… Annual gun homicides: Canada: 300 Sweden: 60 United States: 15,500 It’s the guns.

  • Meanwhile:  Texas has banned more books than *any* state in America.
