Cashless Stores Alienate Customers in the Name of Efficiency

There’s been growing support from both consumers and retailers to move away from cash in favor of digital payment options .It’s one thing for luxury brands to self-select their customers on the basis of price point, but it’s another for a retailer to deny access to a person trying to buy a pack of gum.

New Designs Could Boost Solar Cells Beyond Their Limits

New Designs Could Boost Solar Cells Beyond Their Limits

This process is known as exciton fission and means that the solar cell is able to use high energy photons from the blue-green part of the visible spectrum. Baldo says that using tetracene could bump the theoretical energy efficiency limit up to 35 percent—higher than was ever thought possible for single-junction cells.
