Soon drivers will be able to plot eco-friendly routes. Engineers from Audi of America Inc.'s California Research Labs are working with three California universities to reduce CO2 emissions through intelligent interactions between the driver and the car. "The path between two points can be measured in distance, but it can also be measured in the amount of carbon dioxide that our vehicles emit," says Daniel Rosario, Audi's manager of Connected Vehicles. When drivers choose a route with the lowest CO2 emissions, they can improve fuel efficiency by 20 percent. Rosario notes the technology exists today — it just needs to be integrated into an "intelligent vehicle network."
A make-your-own Star Wars Sith Lightsaber hilt is heftier and better-looking than most others out there, according to its maker, Sean Charlesworth. You can 3D print it from free source files, and there's even a hardware kit available -- not free -- so you can build one just in time for Halloween.
