How A Brick & Rock Battery Is Changing Energy Storage

Grid-scale lithium ion batteries are our current go-to chemical energy storage solution, but they present their own challenges in safety, sustainability, cost, and longevity. However, the competition is … heating up. New forms of thermal energy storage systems built using abundant, cheap materials are on the rise. One company is aiming to sidestep the complications that come with chemical batteries…with a brick battery. And another company’s weapon of choice is a crushed volcanic rock battery. Talk about going back to basics to store massive amounts of energy. But is simple really best?

More homes using heat pumps as cheaper, greener alternative to fossil fuels

U.S. emissions fell during the height of the pandemic as people were stuck at home, but that changed as the pandemic eased. Many researchers, scientists and lawmakers argue that Americans need to reduce their use of fossil fuels much sooner than they may have planned. Miles O’Brien reports on an alternative for home heating that could reduce the use and costs of fossil fuels.

Why The Big Banks Created Zelle

Competition among peer-to-peer payment apps like Venmo, PayPal, Cash App and Zelle have been heating up for the past 10 years. The big banks tried to compete in the space when PayPal first came on the scene 25 years ago, but their business models failed. Now, Zelle, a seven-bank platform, is outpacing its rivals in average transaction value. But a rise in reported fraud activity recently got the attention of Congress, with allegations that the banks aren’t supporting those affected customers.

Watch the video above to learn more about why the banks created Zelle and whether the app can hold its own against the the battle to win in the peer-to-peer payment space.
