[{"role": "system", "content": "A hybrid vehicle uses two or more distinct types of power, such as internal combustion engine to drive an electric generator that powers an electric motor, e.g. in diesel-electric trains using diesel engines to drive an electric generator that powers an electric motor, and submarines that use diesels when surfaced and batteries when submerged. Other means to store energy include pressurized fluid in hydraulic hybrids. Power sources for hybrid vehicles include:  Mopeds, electric bicycles, and even electric kick scooters are a simple form of a hybrid, powered by an internal combustion engine or electric motor and the rider's muscles. Early prototype motorcycles in the late 19th century used the same principle. The first published prototype of an SHB is by Augustus Kinzel (US Patent 3'884'317) in 1975. In 1994 Bernie Macdonalds conceived the Electrilite SHB with power electronics allowing regenerative braking and pedaling while stationary. In 1995 Thomas Muller designed and built a \"Fahrrad mit elektromagnetischem Antrieb\" for his 1995 diploma thesis. In 1996 J\u00fcrg Blatter and Andreas Fuchs of Berne University of Applied Sciences built an SHB and in 1998 modified a Leitra tricycle (European patent EP 1165188).\n"}, {"role": "user", "content": "hello, i drive a prius"}, {"role": "assistant", "content": "That's so cool, hybrid vehicles are really neat, it's fascinating how they use two or more distinct types of power at one time!"}, {"role": "user", "content": "i know, it is a great technology"}, {"role": "assistant", "content": "It's really cool how hybrid energy vehicles can even use efficiency-improving technologies like regenerative brakes, so innovative!"}, {"role": "user", "content": "i did not know abut the brakes"}, {"role": "assistant", "content": "Regenerative brakes are really cool, they slow the vehicle by converting its knetic energy into a form which can be either used immediately or stored until needed."}, {"role": "user", "content": "huh, i did not know that"}, {"role": "assistant", "content": "It's a very useful technology, because regenerative brakes can also greatly extend the life of the braking system in addition to their improvements in overall efficiency of the vehicle."}]
