Think of a traditional hybrid and you probably think of a Toyota Prius. Then, after you've woken from your nap, you probably envision some complex system of batteries and electric motors and gears to capture power when braking and spit it back out when accelerating. Chrysler is now looking to deploy a different way, a seemingly much simpler way that's all based on hydraulics. The vehicle is outfitted with a low-pressure reservoir of hydraulic fluid and a high-pressure chamber filled with nitrogen gas. When braking, pumps move the fluid into the nitrogen chamber to compress it and then, when acceler
