Seven “clean energy hubs” will receive a total of $7B to develop forms of hydrogen production with minimal carbon emissions. And, ahead of the US Grand Prix, an aerodynamicist breaks down the recent engineering changes to F1 cars.<h2>Department Of Energy Announces ‘Clean Hydrogen Hub’ Awardees</h2>The Department of Energy announced seven “clean hydrogen hubs,” which will receive a cumulative $7 billion. Each group will use a host of different approaches to produce hydrogen fuel with little or no emissions.SciFri producer Kathleen Davis talks with Casey Crownhart, climate reporter for MIT Technology Review, to break down <a href="https://www.sciencefriday.com/segments/clean-hydrogen-hub-awardees/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank">the details of this announcement</a> and other top science news of the week, including seals helping map a canyon in Antarctica, the number of living cells in the world, and a very spicy pepper.<h2>Formula One Cars Are Stripping Off Paint To Save Weight</h2>Formula One is known as the pinnacle of motorsport, with cars that can reach speeds of 230 miles per hour. Thanks to the Netflix series Drive To Survive, the sport is more popular than ever.As engineers prepare for the U.S. Grand Prix in Austin, Texas, this Sunday, <a href="https://www.sciencefriday.com/segments/formula-one-paint-weight/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank">teams strive to make their cars as fast as possible. </a>To do so, they try to reduce the ultra-fast cars’ weight by altering the construction of the frame of the car, or finding lighter engine parts. But recently, many teams have been stripping the paint off the cars instead.Even though paint on an F1 car only adds up to about three pounds, <a href="https://www.sciencefriday.com/segments/formula-one-paint-weight/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank">races can be won by milliseconds</a>, so every ounce counts. In the last couple years, many teams made the decision to pare down the amount of paint used on the cars, exposing the natural black color of the carbon fiber below it. It’s why the cars on the grid look darker overall, compared to previous years.Kyle Forster, a former aerodynamicist for the Mercedes-AMG F1 team and a lead aerodynamicist for JKF Consultants, breaks down the engineering changes made to F1 cars in recent years, the newest in paint science, and what aerodynamic changes he hopes to make in the years to come.To stay updated on all things science, <a href="https://www.sciencefriday.com/newsletters/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank">sign up for Science Friday's newsletters</a>.
