After storming out of an infrastructure meeting with House Speaker Nancy Pelosi (D-CA), Senate Minority Leader Chuck Schumer (D-NY), and other congressional Democrats, President Donald Trump took to the Rose Garden for a press conference.

Trump railed against the multiple investigations into him and his administration, also targeting the reporters present for covering the investigations. Trump then asserted that, as long as there are investigations against him, he will not work with Democrats on infrastructure funding:

The electric car is picking up speed as consumers and governments around the world embrace these greener, cleaner high-tech vehicles. Battery technology has evolved to the point where the top-performing EVs can operate for 110 to 150 miles on a single charge — a very respectable range for a commuter. But for someone who is traveling an extended distance, finding a place to recharge remains a challenge in many places.

A countrywide EV charging infrastructure is slowly rolling out in commercial and public places.  Drivers in many places can now charge their car while they are getting groceries or get a quick charge at a gas station. (How quick? The world’s fastest charger gives drivers 120 miles worth of energy in just 8 minutes.) In Sweden, however, drivers need only change their route.

Giant blobs of hardened fat and grease  — “fatbergs,” as they are known to the wastewater industry — are forming in our underground sewer networks.

The New York Times reports that Amtrak train number 188 was carrying 243 people when it crashed in Philadelphia on Tuesday evening. At least eight people were killed and dozens more were injured, several of whom are reported to be in critical condition. According to the Times, the train was travelling at 106 miles per hour when it derailed—more than twice the speed limit on that section of the track—suggesting that the tragedy likely could have been prevented by the installation of a safety system called ‘positive train control.’

Positive train control is designed to prevent human error, such as allowing trains to travel at their maximum speed. CNN reports that such safety systems have been tested and implemented since 2007. After a 2008 rail accident that killed 25 people in California, Congress mandated that safety systems be installed on most heavily travelled passenger rail lines by December of 2015.
