Whether it’s someone outside a cafe stealing WiFi, or concerns about someone snooping or hacking into your home system, geniuses at MIT have developed a slick solution. Engadget.com says that in the past, it took multiple routers to triangulate in order to figure out if someone was outside a business or your home, but the MIT engineers calculate ‘time of flight’ for the signal and then multiply by the speed of light to get the distance. It’s 20 times more accurate than triangulation, and can pick out a correct room in a home 94% of the time and if someone is outside a cafe 97% of the time. It also works with drones with a 2 inch margin of error. There’s already a working prototype, so your next router may be much better at keeping out thieves or hackers.
Transparent wood? What are those Swedes smoking? Actually, scientists at the Royal Institute of Technology have found a way to make transparent wood that is suitable for mass production. It can not only be used for eye catching architecture, but could lead to cheaper solar panels and windows. According to gizmodo.com, they strip out the organic compound that makes the wood brown, then add a polymer to increase strength and provide transparency. Veneer can be made from the material, and it can be laminated to make load bearing panels and beams. Hail resistant skylights could let in more natural light, and lower your heating bills. You may be spending more on curtains or blinds, though!
