Lemon battery Lemon battery A lemon battery is a simple battery often made for the purpose of education. Typically, a piece of zinc metal (such as a galvanized nail) and a piece of copper (such as a penny) are inserted into a lemon and connected by wires. Power generated by reaction of the metals is used to power a small device such as a light emitting diode (LED). The lemon battery is similar to the first electrical battery invented in 1800 by Alessandro Volta, who used brine (salt water) instead of lemon juice. The lemon battery illustrates the type of chemical reaction
Plug-in electric vehicle all-electric vehicle: it uses a gasoline engine and an electric motor for propulsion, but a PHEV has a larger battery pack that can be recharged, allowing operation in all-electric mode until the battery is depleted. An aftermarket electric vehicle conversion is the modification of a conventional internal combustion engine vehicle (ICEV) or hybrid electric vehicle (HEV) to electric propulsion, creating an all-electric or plug-in hybrid electric vehicle. There are several companies in the U.S. offering conversions. The most common conversions have been from hybrid electric cars to plug-in hybrid, but due to the different technology used in hybrids by each
