I know that nobody likes going to war. It's bloody, causes conflict, love ones get hurt, people die, and the list just goes on and on. Though due to the wars countries get into they end up inventing things that have now become apart of everyday use for common citizens.
Sun lamp
Tea bags
These were invented in 1908 during WW1. An American tea merchant started to send small bags to his customers. One point they ended up either on purpose or accidentally dropping the bags into water and well you can figure what happened after that. :D
Vegetarian sausages
I know this one is probably making you scratch your head on why they would make this due to war. During WW1 when the British blockade of Germany began, starvation set in badly in the city. The mayor of Cologne, Adenauer, got a great idea about ways to substitute available materials for scarce items, such as meat. After his long hard work he made the soy sausage that ended up a success.
Microwave Oven
This invention was invented during WW2 by an engineer named Percy Spencer, who was testing a high-powered radio set. He only discovered what he had made when a chocolate bar melted in his pocket while he was working.
Internet
The Advanced Research Projects Agency (now DARPA, the US military's R&D department) played the biggest part of coming up with the internet. Yeah a lot of people took part in it but ARPAnet stands out as the forerunner. ARPAnet expanded quickly to include research from institutions and universities. That lead them to be the testbed for a lot of the infrastructure underlying the internet, like the crucial TCP/IP protocols.
GPS
This one is all thanks to the military which was designed during the Cold war. It was to provide a navigation system for the Polaris submarine-launched intercontinental ballistic missile. The platform for GPS consisted of 24 satellites, this was to allow a receiver anywhere in the world to calculate its accuracy down to just a metre or two. They didn't always let civilians be able to use this system until after May 2nd, 2000. This allowed civilians to get accuracy down to centimetres rather than metres.
Canned Food
In 1809, Napoleon and his army went across Europe. He then reached a point where he needed a way to deliver enormous quantities of good-enough food to the front lines. The French government then held a contest to find anyone that could solve this problem. The cash prize for the winner ended up being 12,000 francs. The man who ended up winning the contest and solving the issue was Nicolas Appert. He designed a sealed glass jar that could be produced a large quantity in factories. Nicolas then used his prize money to build such a factory, sadly the British burned it down during their rampage through France in 1814.
Digital Photography
During the Cold war, one of the most popular inventions to come from this conflict is the Digital Photography. Due to the military having to drop rolls of film out of the sky from spy planes. That became tricky due to the high altitude of the drops and having them float down by a parachute. This invention was first employed in the NASA-Air Force KH-11 satellite in 1976. After that solved the problem the spy planes could then transmit the components back to earth by using encoded radio signals.
ANTIBIOTICS
In 1928 a Scottish scientist by the name, Alexander Fleming, was working on a anti-bacterial agent. To his misfortune it became unusable until WW2 thanks to the infectious diseases that plagued the wounded soldiers. Once the war ended this became a common part of Western medicine, now it's to the point that the overuse of these medicines have become a major health problem.
AMBULANCE SERVICES
The first time this became a thing was in the late 15th century, in the Spanish army. Though the concept of our modern ambulance wasn't until Napoleon’s army. This all became standard issue for Union troops during the Civil War, and in 1869, Edward Dalton, who was a former Army surgeon. Introduced to the Commercial Hospital of Cincinnati the first large-scale ambulance service. At the end of the following year the service had answered 1401 emergency calls.
TAMPONS AND PADS
Kimberly-Clark who ran a lumber company and papermill came across an interesting new application for wood pulp in 1914. She then mixed this material into a fluffy material, which ended up having the ability to absorb 5 times the amount of what cotton can do. She then started to sell her cellulocotton to the military, this providing the soldiers of WWI an efficiently new material for bandaging and sealing wounds. Once the war ended Kimberly Clark was stuck with factories making cellulocotton. Civilian doctors and surgeons weren't making any demands for her new product compared to the military. She ended up thinking most of her factories would end up closing which would have cost hundreds of jobs and millions of dollars. After Kimberly-Clark heard a rumor concerning Army nurses that had served or near the front lines of the war. How the nurses were embarrassed by the cloth flaps that they had to wash and then re-use them. So being on the front lines of battle to help wounded soldiers was a nightmare having to keep them clean. Thanks to this invention that nightmare was over.
Even though nobody likes war and what it brings, it's still good than we did for we wouldn't have any of these inventions if we didn't.
