The hybrid diesel locomotive is an incredible display of power and ingenuity. It combines some great mechanical technology, including a huge, 12-cylinder,  two-stroke diesel engine , with some heavy duty  electric motors  and generators, throwing in a little bit of computer technology for good measure. This 270,000-pound (122,470-kg) locomotive is designed to tow passenger-train cars at speeds of up to 110 miles per hour (177 kph). The diesel engine makes 3,200  horsepower , and the generator can turn this into almost 4,700 amps of electrical current. The four drive motors use this electricity to generate over 64,000 pounds of thrust. There is a completely separate V-12 engine and generator to provide electrical power for the rest of the train. This generator is called the  head-end power unit . The one on this train can make over 560 kilowatts (kW) of electrical power. This combination of diesel engine and electric generators and motors makes the locomo­tive a  hybrid vehicle . In t

Many people have probably owned a hybrid vehicle at some point. For example, a  mo-ped  (a motorized pedal bike) is a type of hybrid because it combines the power of a  gasoline engine  with the pedal power of its rider. In fact, hybrid vehicles are all around us. Most of the  locomotives we see pulling trains are  diesel-electric hybrids . Cities like Seattle have diesel-electric  buses  -- these can draw electric power from overhead wires or run on diesel when they are away from the wires. Giant  mining trucks  are often diesel-electric hybrids.  Submarines  are also hybrid vehicles -- some are  nuclear-electric  and some are  diesel-electric . Any vehicle that combines two or more sources of power that can directly or indirectly provide propulsion power is a hybrid. Most hybrid cars on the road right now are gasoline-electric hybrids, although French car maker PSA Peugeot Citroen has two diesel-electric hybrid cars in the works. Since gasoline hybrids are the kind you'll find at

Recently, the world’s largest solar-powered office building was unveiled in Dezhou, Shangdong Province in northwest China. The 75,000-square-meter office building bears a resemblance to an ancient sun dial and reminds visitors of the importance of renewable energy. Today, we have for you the world’s largest solar powered creations that amaze us with their size and purpose they’re built for. Hit the jump to see them all. World’s largest solar-powered office building The world’s largest solar-powered building has been unveiled in Dezhou, Shangdong Province in northwest China. The 75,000-square-meter office building is based on the sun dial structure and marks the urgency of seeking renewable energy to replace polluting fossil fuels. The building provides space for exhibition centers, scientific research facilities, meeting and training facilities and a sustainable hotel. Dubbed the Sun and the Moon Altar micro-row buildings, the architecture features the Chinese characters for sun
