In the decade of the seventh decade of the last century, the basic field of electrical use was telegraphic era.
The 8th century is the era of electric lighting. The development of cities, the emergence of blocks and massive buildings, factory buildings and factories urgently worsens a new, more powerful, livelier source of light that can be distributed in many places. Lighting thus becomes the primary field of application of electricity. On this occasion, industrial generators and power plants have been set up, which have opened the road for electricity as a force in the powerful drilling industry.
These victories of elctricity since the beginning of development are largely due to Edison's work.
In October 1879, Edison obtained a vacuum (a rare balloon) near a million atmospheres (much less than the vacuum the technique can get today, a very great achievement at that time).
