Two people who meet this requirement were introduced by the same person:
Thomas Michili
He is a talented mechanical and chemical engineer who plays an important role in preventing gasoline engines from "knocking". This problem is caused by inferior fuel, and it is pre-ignition (! ), leading to engine wear, damage and premature death (engine) ... The antidote designed by Little Midgley is to improve the octane level of gasoline, which is the root of the problem:
Tetraethyl lead, as a booster, is added to fuel to form "leaded gasoline" (leaded gasoline). The effect is very remarkable, but there are also obvious disadvantages:
Lead is a cumulative poison that affects many body systems.
lead is distributed in the body to the brain, liver, kidneys and bones. Over time, it will be stored in teeth and bones. Human exposure to lead is usually assessed by measuring lead in blood.
During pregnancy, lead in bones will be released into the blood and become a source of contact with the developing fetus
Any known level of lead exposure has harmful effects.
exposure to lead can be prevented.
Due to shocking bad luck-or maybe he was cursed *-Thomas Midley Jr. played a major role in the development of the first batch of chlorofluorocarbons (CFCs), and his brand name is better known as Freon.
It is also doomed to be banned, but this time it is not out of concern about its direct impact on human health.
(Unless Freon is used as a fire prevention measure to immediately flood sealed rooms with very expensive computer systems, when it happens, anyone who is unfortunate around will suffocate immediately. )
It was found that at about the same time, a huge hole was observed in the ozone layer of the Arctic, and air pollution was in the form of wireless chlorofluorocarbons (CFCs), the market leader of Freon, now from air-conditioning aerosol cans, which (at that time) was considered as a harmful greenhouse gas than carbon dioxide or methane.
Not only is it incredibly stable, so it lasts for a long time, destroying the ozone layer that protects most habitable areas of the earth from harmful radiation, but-at least in theory (according to the understanding of environmental damage at that time)-the ongoing destruction may be permanent ...
Thomas Mediglie Jr. won more than 1 patents in his career, and the disastrous side effects do not seem to be the same as the progress of conventional science and technology.
