美国橡树岭国家实验室(ORNL)的一位研究人员发明了一种可变工作容积液态金属(LM)发动机。据说该发动机装在汽车上可使车辆的燃料经济性达到42.5km/L。这种发动机输出的是交流电(AC)功率,该交流电是通过液态金属钾或钠在密封的管子里往复地经过一个
A researcher at Oak Ridge National Laboratory (ORNL) in the United States invented a variable-volume liquid metal (LM) engine. It is said that the engine installed in the car can make the vehicle fuel economy reached 42.5km / L. The output of this engine is alternating current (AC) power which is passed through a sealed tube of liquid metallic potassium or sodium through a
