{"title":"Cool running heat engines","authors":"W. Courtney","doi":"10.4024/12co20a.jbpc.21.03","DOIUrl":"https://doi.org/10.4024/12co20a.jbpc.21.03","url":null,"abstract":"Newcomen invented the atmospheric steam engine in 1712. This employed steam at one atmosphere pressure and a temperature of around 100 ° C. In the following century, by the time of “The Great Exhibition of the Works of Industry of all Nations” in 1851, materials technology had advanced sufficiently for engineers to build far more efficient steam engines. These operated at several atmospheres of pressure and temperatures well above 100 ° C. It was only later, however, in the second half of the nineteenth century, that the science of thermodynamics reached maturity and engineers were able to further improve on steam engine design by using science instead of experience. The fact that thermodynamics only emerged long after powerful steam engines were being employed to help us conquer nature and build empires has left us with several questionable legacies: (i) we have learned to live with several terms and concepts that do not make thermodynamic sense, but have been tolerated because they do not seem to do any harm either; (ii) there is a common belief that we human beings should use technology to overcome nature, rather than forming a partnership with it; (iii) cool running heat engines that recycle energy can be found in nature but humanity has chosen to move in the opposite direction, building ever hotter and higher pressure heat engines in order to increase their power. In this paper we discuss some of the accepted terms and concepts that do not make thermodynamic sense, and then use this fresh insight to propose a new class of cool running heat engines for generating electricity. Based on these insights, the author has filed patent applications describing clean cool running heat engines. However, mindful of the climate emergency facing our planet, these patents have been allowed to lapse. This means that university researchers, commercial enterprises and others are free to develop them as open source technology, without seeking the author’s permission or paying him royalties.","PeriodicalId":88911,"journal":{"name":"Journal of biological physics and chemistry : JBPC","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45686377","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}

However, concerns of contamination of the natural habitat by these crops to produce mutant “Triffid” like strains have not materialised. The modifications were introduced to make the crops tolerant to weed killing herbicides and in the last 20 years it is becoming apparent that these herbicides containing glyphosate are the real cause for concern. Glyphosate is now classed by the International Agency for Research on Cancer as \"probably carcinogenic in humans\" but the last 20 years have seen the advent of food costs rising less than inflation and greater productivity for farmers. For most people the cost of organic (grown without hebicides) crops makes them totally impracticable and only the wealthy in Western nations can afford such food over a longterm basis. We all take risks in everyday life and eating is just one of them; the issue then, is how much of a risk are we taking?","PeriodicalId":88911,"journal":{"name":"Journal of biological physics and chemistry : JBPC","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44361481","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}
