Pick-up ions are carried along by the solar wind, the stream of charged particles flowing continuously from the sun. (This flow is blocked by the interstellar medium to form the boundary of the heliosphere.) Pick-up ions are much hotter than the particles that make up most of the solar wind, which contributes to the heliosphere's weird shape, study team members found. … [Read more...] about Is our solar system shaped like a deflated croissant?
Tackling the challenge of making clean water accessible, a Colombian team proposed a ready-to-assemble device for solar water desalination augmented with an education strategy to assure social appropriation of the technology for the Parenskat-Wayuu ethnic community in the arid region of La Guajira, Colombia. Desalination, not surprisingly, was at the heart of proposals from teams from Ecuador, the U.S., and Germany, as well. An entrant named Daniel Hodges from the U.S. proposed a wind-powered vacuum distillation system to help water-stressed coastal small families around the world. … [Read more...] about Finalists chosen in global engineering challenge to save humanity
That problem is solved by the Stick Up Cam Solar, which connects its battery pack to a mountable solar panel. This model will keep its battery topped off as long as it's outside and getting enough sunlight. Finally, there is the Elite Stick Up Cam, which costs twice as much as a regular Plug-In Cam. This version must plug into your router through an Ethernet cable, and comes with an improved FOV and a mounting bracket that lets you place it on the wall or ceiling. The non-Elite Ring Cams can be mounted on your wall but require an add-on mount to affix to your ceiling. … [Read more...] about Eufy Indoor Cam 2K vs. Ring Stick Up Cam: Which should you buy?
To Battery or not to Battery The new Ring Stick Up Cams are back and better than ever, but before you snatch up one — or four — for your home, you should be aware that not all Ring Stick Up Cams are created equal. We've looked beyond the names and the power sources to see the differences you need to know about before you buy. Ara Wagoner and Jeramy Johnson … [Read more...] about Ring Stick Up Cam Plug-in vs. Stick Up Cam Battery: Which one is right for you?
Located on the northwestern coast of Ellesmere Island in Nunavut, the Milne Ice Shelf is about 4,000 years old. Signs of the impending breakup were spotted by Adrienne White, an ice analyst at the Canadian Ice Service, Environment and Climate Change Canada (ECCC), according to WIRL. On Aug. 2, the Canadian Ice Service shared satellite images in a Tweet, reporting that "above normal air temperatures, offshore winds and open water in front of the ice shelf are all part of the recipe for ice shelf breakup." … [Read more...] about Canada’s last intact ice shelf just collapsed
