The invention of electricity , or rather the development of the science of electrification phenomena, was materialized by Coulombs law (1785), allowing Volta to create the first electric battery (1800) then to Thomas Edison to light up factories and homes (1879). If the electrical phenomena have alw
The electric battery is a direct current generator device discovered and invented by Count Alessandro Volta , Italian physicist. Starting from a phenomenon discovered by Galvani, Volta studies the electrical tensions which are established between different metals and develops an accumulator capable
The wind was with water the first source of energy exploited by man. The first windmill first appeared in the East, in Ancient Egypt and in Persia where it was exploited for irrigation from the year 600 BC. The wings are arranged radially on a vertical axis. The idea of this type of mill will be t
