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

BALTIMORE, Md. — A mom walks into a bar. There is no punch line. Just a punch in the gut. A mom sold her baby, Marion Louise Smith, for cash and her older daughter for a car 51 years ago at a bar that use to be called Ken Tins. It sat right on the corner of Chester and Fairmount in Butchers Hill in Baltimore.Kenneth Suggs was asked if he wanted the baby for cash. Shocked and concerned for the child, Suggs used his whole paycheck to take Smith.Suggs, an electrician, and his IHOP waitress wife Gail took in Smith and raised her. Smith now lives with her family in Middle River, Maryland.But when her father died, his wish for Smith was to find her sister.  And that's what she's doing. 761

Bright colors paint the streets and sides of buildings across America, as murals are created as a symbol of solidarity for the black community.But many of the murals already have scars, vandalized with tar, tire marks, and words of hate."No, not surprised. Racism is still prevalent in Santa Barbara, as it is in the entire land, unfortunately," said Ron Paris Green, a musician who lives in Santa Barbara, California. When a mural paying tribute to George Floyd went up in the downtown area, Green jokes that he thought he was in a different city. Santa Barbara has strict rules on what signs are allowed on buildings. The town has a uniform architecture of red tile roofs and white stucco walls. "To have a Black man on the side of a wall, which is supposed to be white, is not something a lot of people want to see, especially in Santa Barbara," said Bix Kaufman, owner of EOS Lounge. After the death of Floyd, Kaufman broke the city's longstanding tradition, inviting an artist to transform the white wall outside his club. The overwhelming white community has a Black population of less than 2 percent."This is, I think, one of the strongest statements in Santa Barbara right now, and it feels really good. And there's been so much positive feedback," said Kaufman. Green visits the mural twice a day now, "I'm very optimistic, yes, because of the young people stepping for the cause."He's been marching with young activists and hopes to send some to a massive march planned for this August in Washington D.C., led by Al Sharpton and Floyd's family. Green's donating proceeds from his album, Ron Paris: "Soul Mate", which is available on Amazon. But the racism the mural was designed to combat resurfaced with a can of yellow paint. The words "All Lives Matter" sprayed over the words "I can't breathe."Vandalism of the Santa Barbara mural is far from an isolated incident. Similar headlines can be found across the country, from Vermont to Texas, Florida, Ohio, and Oregon."It should be a big wake up call for all of America, that there's a lot of problems that need to be fixed and it's not going to happen overnight. But we can start with having justice served," said Kaufman. But in the face of hate, artists and activists have grown more resilient.In Santa Barbara, the mural was not only repaired within hours but also granted permission by the city to stay up indefinitely, according to Kaufman. "We heard the word revolution during the 60s. this is a cultural revolution," said Stan Holder, a poet and activist. Holder has helped cover the Santa Barbara mural with stories of pain endured by generations."How many more innocent Black lives must be sacrificed for us to all realize we are all in this human race together?" Holder reads off the wall."People go back to their regular lives and sometimes forget this is still a problem," said Kaufman.He hopes the mural serves as a constant reminder of the years of work ahead needed to fight systematic racism and achieve equality for all. 3009
