The Sonar
The sonar then versus now is one of the most important functions of a ship. Reginald Fessenden was a Canadian Engineer and Inventor, he is the creator of the sonar in 1915. Fessenden made the Sonar system, so that it can use underwater sound waves that can reflect off of a surface of an object to detect and find it. It can find stuff like submarines, other boats or even mines. -
The Process to Extract Helium From Natural Gas
In 1915 Sir John Cunnungham Mclennan was a physician in Canada and he was working on a way to extract helium and finally figured it out. The way Cunnungham found out to do it was by using a cryogenic process. Where the gas is cooled to very low temperatures, causing other elements to liquefy or become solid, leaving helium as a vapor that can be separated and then purified. Later Cunnugham then gave this info to the Canadian government and started making extraction plants to help with the war. -
Lewis Light Machine Gun
The first weapon that Canadians first went to war with was 3 different Colt machine guns. The Colt machine gun good, it was immobile and often jammed after a large amount of rapidfire shots. Replaced in 1916 by the Vicker machine gunheavier and immobile. However, it was a more reliable machine gun. Lastly, the Lewis Light machine gun It was a reliable light machine gun and it could be carried around. It helped advance some of Canada's war tactics and helped them on offence as well as defence. -
Ontario Hydros Queenston-Chippawa Hydroelectricity Power Generator
Ontario Hydro's Queenston-Chippawa power generator project was under construction for 4 years (1917-1921) and was one of the largest engineering projects since the Panama Canal. It was made by Nikola Tesla, (yes he did make or more like made the plan to do it, plus he died in 1943) This Hydroelectricity power generator not just powered basic things like light in urban areas and factories, it helped to link to mining and resource creation like aluminum or even paper. -
The Variable Pitch Propeller
A New Brunzwick Engineer named Wallace Turnbull was the first to make the Variable Pitch Propeller. He showed his invention to the government which showed interest in it. However, it was burned in a fire, but remade again in 1925. 2 years later it was successfully tested in the Canadian Air Force and was sold to 15 different manufacturing companies. This
propeller is good because it can change its adjusted to the use, for example it can be used for lifting off the runway or cruising in the sky. -
The discovery of Insulin
Scientists always thought the key to preventing diabetes and controlling a normal metabolism was some kind of internal secretion of the pancreas. However, finnaily in University of Toronto a team of doctors and researchers led by Dr. Frederick G Banting, did multiple tests of trying to make something in a different angle in 1921 spring of 1921. Then finished the invention of insulin in 1922 after failing to make it pure enough. -
The Snowmobile
The creator of the snowmobile was created by Joseph -Armand Bombardier, who was a young Quebecois inventor, who created the first snow vehicle prototype. He was known to play with machines, which he started playing with a ford engine and some wood. That was how the first snowmobile prototype was ever made. However, once Joseph had turned 15 his father made him dismantle it because it had a giant open propeller that could have hurt him badly. -
The Battery less Radio
Edward S. Rogers Sr. was a Canadian Inventor who was the first person to create the battery-less radio. The reason why this radio was such a hit in sales, is that it can simply be connected to an outlet and it took such little electricity that the bill didn’t even change. Therefore, it was sold throughout and everywhere in Canada. -
The Snow blower
Arthur Sicard the inventor of the snowblower. He wanted to make this invention to help farmers get snow off their fields in an easy and quick way. After 31 years to create this machine, he finally unveiled it in Montreal, Quebec. The first snowblower was very different, it was a truck with a scoop and a snow throwing chute. It threw the snow up to 90 feet or put it in the back of the truck.Interesting realization: in the present day the snowblower truck really looks like a wood chipping machine. -
The Expansion of the Hudson Bay Railway
Canada's railway system was one of the best however, they weren’t done with it after WWI. The construction of the Hudson Bays railway was finished and officially resumed in 1929 (phase 3). It was built to provide access to a saltwater port. The companies that were making the railway were the Winnipeg and Hudson's Bay Railway and Steamship Company. There were different phases of the railway, Phase 1 1875-1886 and phase 2 3 1909 1936. Phase 3 was most likely started in 1929.
