Fuel Cell:
Currently, the use of renewable energy has increased in the world. And fuel cell is one of the means of this renewable energy. But how was this fuel cell discovered? Fuel cells are devices that generate electricity through a chemical process. In 1838, the German scientist Friedrich Schubian invented the first fuel cell principle. In February 1839, the amateur scientist and barrister Sir William Robert Grove was able to implement the idea of power generation through the Fuel Cell. However, the first commercial use of fuel cell began in 1956. The chemical component of the fuel cell can be used every time. Because, fuel cell is a kind of renewable fuel medium. The main chemical components of a fuel cell are hydrogen and oxygen from the air. Moreover, among other chemical elements, hydrocarbon compounds such as alcohol are used. Different types of fuel cells are currently available and it depends on the chemical composition. Variations in the chemical composition of the fuel cell
Plant life:
Although scientist Sir Jagadish Chandra Bose studied physics, he started researching physics as well as biology. At this time his deep interest in plants can be noticed. He was able to understand in one phase of research on different plants, that plants also feel and respond to excitement in the flow of electricity. And it is not at all correct to say that not only animals have the ability to respond, but also plants. Scientist Jagadish Chandra attended the International Conference on Physics held in Paris in 1900. The theme of his lecture here was ‘The Unity of Electrical Response to Organisms and Inanimate’. There he spoke at the Bradford meeting of the British Association on the relationship between organisms and matterOn the basis of scientific research, scientist Jagadish Chandra wrote ‘Responses in the living and non-living’ in 1902. In his two books, published in 1908, he proved that the same response is found in any way to stimulate plants or animals. He went to England and America. American scientists were quite interested in his discovery. Scientists in England were slowly acknowledging the veracity of the research. Returning to the country, Sir scientist Jagadish Chandra started the third phase of research. To prove how plants can respond to different conditions, scientist Sir Jagadish Chandra Bose continued his research activities on several types of plants including eggplant, cauliflower, carrot, radish, almond, turnip. During this time he did extensive research on plant life and reproduction. At this stage of his research, he invented his famous instrument, the Crescograph. He invented a special device called a crescograph to detect the growth process of plants. With this instrument he was able to measure the growth of the tree. Again in 1914 he went to England for the fourth time. This time, during the journey, he only took his scientific instruments with him, along with the Lajjavati and Banchallar trees. These trees can respond easily. He proved at Oxford and Cambridge universities, as well as at the Royal Society, with the help of his invented instruments, that trees, like living things, have life, they too are resonated with the excitement of injury. In 1910, the scientist Sir Jagadish Chandra Bose published the full results of his research in the form of a book, Response in the Living and Non-Living. The research of the best scientists of the subcontinent is worthwhile. The results of his research spread around the world. He was the first to realize the existence of life in plants and was able to prove it.
Steam engine:
Scottish scientist James Watt invented this steam engine. He had an innovative ability. He became interested in steam engines while studying at the University of Glasgow. James Watt observed the repair of the engine invented by Thomas Newman in 184. From this he came up with the idea of inventing a more advanced engine. In 189 he patented the first steam engine. That engine had separate cond
