His story has become a myth, and myths must live on. After all, they can't even be touched by time. The notoriety of the famous aviator was also preserved due to Păstorel Teodoreanu’s poem, made into a song by Gherase Dendrino in the summer of 1941: \"He went hunting, Agarici / He went to hunt Bolsheviks...”1, a fashionable hit between 1941-1944, a period during which Romania was leading a crusade against communism! Broadly speaking, Horia Agarici's life was accessible to the general public after 1989, and it appeared, in part, even on the ultra-publicized Wikipedia [1]. But most of the details were brought to light, naturally, by post-communist newspapers. Horia Agarici (born April 6, 1911, Lausanne, Switzerland, d. 1982, Constanţa, Romania) was a major aviator in the Romanian Air Force, one of the elite aviators of the Romanian Army during the Second World War, a poet and a Romanian author [2].

Due to the vast amount of carbon dioxide released in the atmosphere by conventional power plants and the negative influence on the climate, new ways of producing electricity must be developed. A gyroscope consists of a spinning flywheel of mass m mounted in a suspension frame that allows the flywheel’s axle to point in any direction. In this analysis, one end of the axle is supported by a pylon situated at a distance R from the center of mass of the spinning flywheel. In order to generate electrical energy at this low speed, the same approach should be used as in wind power electrical generators. In this case, the wind and propeller are substituted by a gyroscopic system and gravitational attraction. Based on the conservation of angular momentum, the gravitational attraction can be used to create a precession strong enough to provide the energy and torque necessary to activate an electric generator similar to those in wind power generators. Instead of recovering the energy from this kinetic energy, we can use the precession rotation created by gravitational attraction to create the necessary kinetic energy.","PeriodicalId":158636,"journal":{"name":"Review of the Air Force Academy","volume":"104 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133877651","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
