Toyota concept vehicles (2000–2009) Fine-S and was shown at the October 2003 Tokyo Motor Show and the January 2004 North American International Auto Show. The Fine-N uses a hydrogen fuel cell electric hybrid system which drives four independent 25 kW electric motors - one in each wheel. The hybrid system uses a Lithium-ion battery under the seats. Control is by drive-by-wire. The Alessandro Volta is a concept car developed in the collaboration of the Japanese manufacturer Toyota and the Italian design company Italdesign Giugiaro. The concept vehicle named after Alessandro Volta, the Italian physicist who invented the battery (and the namesake of the volt
Georg Ohm Georg Ohm Georg Simon Ohm (; ; 16 March 1789 – 6 July 1854) was a German physicist and mathematician. As a school teacher, Ohm began his research with the new electrochemical cell, invented by Italian scientist Alessandro Volta. Using equipment of his own creation, Ohm found that there is a direct proportionality between the potential difference (voltage) applied across a conductor and the resultant electric current. This relationship is known as Ohm's law. Georg Simon Ohm was born into a Protestant family in Erlangen, Brandenburg-Bayreuth (then a part of the Holy Roman Empire), son to Johann Wolfgang Ohm, a
