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

BIRMINGHAM, Ala. (AP) — Alabama voters have approved a measure that would begin the process of deleting racist language from the state's 119-year-old constitution. Voters in the majority white, the conservative state rejected similar proposals twice since 2000. With more than 1.7 million votes cast, the amendment passed with 67% support on Tuesday, the Associated Press reported.That means more than 585,000 people voted against it, the AP reported. 459

  

BONITA, Calif. (KGTV) -- Sweetwater Bike Park in Bonita is the first of its kind for San Diego County parks, and it was a long time in the making."As an organization, we have been advocating for over 10 years for this type of park in the county, so we're thrilled," says Susie Murphy, the Executive Director of the San Diego Mountain Biking Association.The park opened in January, and riders of all ages and levels showed up on two wheels."On opening day, I like to say the youngest rider was seventeen months old, and the oldest was seventy-four. It's for all ages, from tiny kids on their Strider bikes, up to teenagers from the neighborhood on their BMX bikes," Murphy says.And Murphy says she loves the design of the park. It comes with jumps, two flow trails, and a skills zone."Every day it puts a smile on my face," Murphy says. Unfortunately, soon after the park opened, it had to be shut down due to the COVID-19 pandemic. "We did not know what to expect, it was definitely a disappointment," added Murphy.The park was closed for a couple of months, but is now back open for business, but with a few rule changes."Right now we're only letting fifty people come in at a time," says Park Ranger Adair Flores. "They are required to wear a mask when they come in and they do have to stay six feet apart from each other. They can't group up in the gazebo areas when they are riding, and it's recommended they wear a mask, but you know, it's harder to breathe with it." 1482

  

BUFFALO, N.Y. — A Buffalo man seen in cell phone video being punched in the head repeatedly by a Buffalo police officer plans to sue the city, the police department, the police commissioner and both officers involved in his arrest.An attorney representing Quentin Suttles, 30, has filed a notice of claim in State Supreme Court. Suttles claims Buffalo Police Officers Ronald Ammerman and Michael Scheu used excessive force when they pulled him over and arrested him on May 10.The arrest, which was recorded on a bystander's cell phone video and police body cameras, shows one of the officers punching Suttles in the head repeatedly while he is on the ground.The claim also accuses the city, the police department and Buffalo Police Commissioner Byron Lockwood of not providing officers with proper use of force training and not providing adequate supervision of their actions.According to the claim, Ammerman and Scheu followed Suttles' vehicle for several minutes and pulled him over after he "committed a minor traffic offense." Police said Suttles was going the wrong way down a one-way street.During a search of Suttles after he stepped out of his car, the claim states the officers "had engaged in prolonged grabbing of his genitals while finding no contraband. The officers...then grabbed his hands and while throwing him to the ground advised that his hands need to be out of his pockets...while his hands were either against the car, or being held by the officers."Suttles' attorney said when a bystander recording the altercation asked why they were punching Suttles in the head, the officers responded by saying they were saving his life because he was trying to eat drugs.The claim also accuses the officers of not seeking medical treatment for Suttles until the following day, despite the fact that he suffered serious injuries.The police report from the incident states that officers noticed a strong odor of marijuana coming from Suttles' vehicle after pulling him over for driving the wrong way."While conducting a pat down, searched defendant did push off vehicle and fight with officers," the police report states. "Defendant continued to fight and reach in his pants, ignoring officers command to stop resisting."The report also says officers recovered a white powder substance from Suttles' left pocket.In an attempt to handcuff Suttles, police say he was taken down to the ground. In May, a police source said that Suttles had drugs on him and tried to destroy the drugs while officers were handcuffing him.In the video, one officer says, "let it go," and "I'm trying to get the drugs.""You're making this hard on yourself," another officer says in the video.A woman off-camera also told Suttles to "stop resisting." Suttles told the woman that he wasn't resisting.The Erie County District Attorney's Office is investigating the incident.Both officers remain on duty with the Buffalo Police Department.The lawsuit comes weeks after a 75-year-old protester was shoved to the ground by Buffalo police officers while peacefully demonstrating against police brutality after curfew. Those two officers have been charged with felony assault.This story was originally published by WKBW in Buffalo. 3218
