Businessman's patent

Edison was a scientist, and he really made a lot of contributions to the progress of human civilization. At least we can enjoy the night with light today, because of Edison's contribution, because he invented the electric light. Of course, Edison was not entirely a scientist who did not pay attention to personal interests, but devoted all his money. At the same time, he also created huge benefits for himself.

First of all, Edison invented direct current, which created great benefits for him personally. In Edison's personal company, the patent fee for direct current is not a small sum. As another great scientist at the same time, Nicholas? Tesla, whose invention of alternating current is improved on the basis of direct current, is safer, more stable and more energy-saving, but as two opposites, Edison has always denied the fact that alternating current is safe.

Edison mostly published articles in front of the media or newspapers to boycott Nicholas? The insecurity of Tesla's alternating current, therefore, Edison's practice was also commented by everyone. He became an interested businessman, and it was indeed the case. Tesla is a very talented scientist, but he put more energy into scientific research all his life. Although its fame is not as high as Edison's, I personally think that Tesla has contributed and surpassed Edison to some extent.

Indeed, in modern life, alternating current has completely banned direct current. And Tesla has a lot of academic research, which is a very advanced science today. If Tesla can be produced in another era and protected accordingly, then Tesla can make more extraordinary achievements in this scientific field.
