The German company Solmove has developed a "solar carpet" that can be rolled out on cycle paths, roads, car parks and garage access roads. It consists of many small glass tile modules that serve as solar cells and are electrically and mechanically connected via a fabric. The break and non-slip safety glass has a nubby surface structure and drains the water much better than conventional road surfaces. The surface cleans itself. In addition, a nanocoating ensures that nitrogen oxides are decomposed.
Apple presented an updated version of the Safari browser at its developer conference to protect users from being tracked while browsing Facebook, among other things. Monitoring takes place, for example, through comment fields embedded by Facebook in external pages and like buttons that target the page visitor, even if he or she does not use these tools. The browser will be available within the "macOS Mojave" operating system and will open a pop-up window when the user visits certain websites. It informs the user about the data collection, so that he can then agree to it or prevent it.
Walmart has launched the personal shopping service "Jetblack" in the USA, which enables customers to order products such as gifts by text messages or with the help of a photo and have them delivered on the same day. The service uses artificial intelligence in combination with the experience of employees to suggest suitable products. If the choice of products is not the right one, the customer can inform by text message and have the products picked up again. The membership of Jetblack costs $50 per month and is only possible by invitation.
Researchers of the University of Minnesota have developed a portable, low-cost 3D printer that allows electronics to be printed directly on the skin. The electronics are printed with a silver flake ink that can cure and conduct at room temperature. A motion sensor prevents errors from occurring during printing when the hand moves minimally. If the electronics are no longer needed, they can be removed or washed off with tweezers. For example, sensors or solar cells could be temporarily printed on the skin.
