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
Volta potential of the Volta potential. Volta potential The Volta potential (also called Volta potential difference, contact potential difference, outer potential difference, Δψ, or "delta psi") in electrochemistry, is the electrostatic potential difference between two metals (or one metal and one electrolyte) that are in contact and are in thermodynamic equilibrium. Specifically, it is the potential difference between a point close to the surface of the first metal, and a point close to the surface of the second metal (or electrolyte). The Volta potential is named after Alessandro Volta. When two metals are electrically isolated from each other, an arbitrary potential difference
