Beyond the beaches of the world, lies the potential for oceans of energy."I'm very excited about this because it's a very renewable energy-based technology,” said Professor Bruce Logan of Penn State University.Logan and university researchers recently created a device that removes salt from seawater in a cheaper way, allowing that water to then be used to create a renewable form of hydrogen fuel.“There's a lot of interest in renewable hydrogen,” Logan said. “Most of the hydrogen made today is made from fossil fuels, and so, we're interested in making that hydrogen from water.”That involves splitting water molecules into oxygen and hydrogen. The problem? Seawater also has salt, which needs to be removed first and that’s expensive to do.However, the “seawater electrolyzer” that Logan and his team worked on takes care of that issue cheaply by using a special membrane and without requiring expensive desalination plants. The findings were recently published in the Journal of Energy and Environmental Science.“Hydrogen is a great fuel,” he said. “It's been examined as a fuel for many decades now.”About 97 percent of all the water on earth is in the ocean, which means if it could be used efficiently to make hydrogen fuel, it could be a game-changer.“As we look to de-carbonize our fossil fuel infrastructure, we also can use it primarily for heavy-duty vehicles,” Logan said. “Airbus is looking to actually make airplanes that fly on hydrogen.”For now, though, their device would need to be scaled-up to a much larger version.“There are many nations and companies and nations across the world looking to do this. One of the biggest proposed hydrogen plants is in Saudi Arabia -- billion,” Logan said. “I would hope to convince them that it might be cheaper and better to use seawater directly, you know, in a system like this.”It’s a possibility that might one day create a bridge between our energy needs on land and the power in the sea. 1962

Because of my strong focus on the China Virus, including scheduled meetings on Vaccines, our economy and much else, I won’t be able to be in New York to throw out the opening pitch for the @Yankees on August 15th. We will make it later in the season!— Donald J. Trump (@realDonaldTrump) July 26, 2020 308

  

Baltimore Police confirmed a man was hit by a light rail train and cut in half at 8:35 a.m. Thursday.The accident occurred at North Howard and West Lexington Street, roughly a block south of the Lexington Market Light Rail stop. Police believe the incident occurred somewhere between Mulberry Street and Saratoga Street, with the person's body ultimately becoming dislodged from the train near West Lexington Street, Baltimore Police Chief Spokesman T.J. Smith said in an update around 10:30 a.m. There were passengers on the train at the time of the incident, Maryland Transit Administration Public Information Officer Paul Sheppard confirmed. Investigators are operating in a large scene that spans Howard Street from Mulberry Street south to Baltimore Street. "It's a large scene that spans several blocks," Smith said.  856

  

Before he crashed and died, the airline worker who stole and flew a passenger plane in the Seattle area Friday had a wide-ranging discussion with air traffic control -- at one point expressing confidence in his flying ability because "I've played some video games."In audio recordings posted on Broadcastify, the man can be heard both resisting and seeking help as a controller and others tried to guide the otherwise unoccupied Horizon Air plane to a landing.The Pierce County Sheriff's Department described the man as suicidal but did not elaborate. At times he was apologetic, expressed his desire to fly toward the nearby Olympic Mountains, worried about lightheadedness and expressed shock at his fuel level's rapid decrease. 738
