6 hypermiling cars that get over 100 miles per gallon
By Cat DiStasioFuel efficiency is one rating that can really set a car apart from the pack. Although you can't yet walk into just any dealership and drive away in a vehicle that gets more than 100 miles a gallon, there are some sweet rides out there that demonstrate just how incredibly efficient a car can be. To get a better idea of what the uber-efficient car of tomorrow looks like, we've compiled some of the most efficient vehicles on the planet, all of which exceed that 100-mpg marker. In fact, most of the cars featured here leave that rating in the dust, and several break into the quadruple digits.
Arctic drone is tough enough to monitor icy waters
Sure, there are already drones out there that can take a bruising, but can they survive the brutally cold Arctic Ocean? Laval University's Argo drone can. The newly developed robotic submersible can reach depths of 6,560 feet as it collects data about organisms in bitterly cold waters, and its laser scanning system helps it avoid ice whenever it returns to the surface to transmit data. Not that Argo needs to poke its head above the water very often -- it can run for up to four years at a time. The machine is still in testing at the moment. If everything goes well, however, the drone will be tracking the biological effects of climate change within a matter of months.
