Summary: News: Researchers run a gas turbine on pure hydrogen in world first | New Atlas (01:51) Gas turbines are found in aircraft, trains, ships, generators, pumps, compressors and all sorts of other places. 90% currently run on natural gas, which produces carbon dioxide when you burn it In the race to zero emissions by 2050, several organizations, including General Electric, have been looking into transitioning gas turbines to burn green hydrogen as a clean fuel source.As of now, GE has more than 100 turbines running on at least 5 percent hydrogen fuel by volume, and they say they are on the path to 100 percent. Researchers at the University of Stavinger in Norway say they've beaten everyone to the punch, claiming that they've had a 100 percent hydrogen-burning gas turbine running since mid-May this year.Runs its own micro gas power plant, and its gas turbine produces heat, electricity and hot water for hydronic heating. Professor Mohsen Assadi, leader of the research team, states:“We have set a world record in hydrogen combustion in micro gas turbines. No one has been able to produce at this level before … The efficiency of running the gas turbine with hydrogen will be somewhat less. The big gain though, is to be able to utilize the infrastructure that already exists.” Eventually, these kinds of projects will lead to conversion kits that can keep old turbine equipment alive while moving it to zero-emissions fuel sources.But this process needs to become economically viable, which means the price of green hydrogen needs to come down substantially. First successful treatment of severe pulmonary hypertension with umbilical cord stem cells | MedicalXPress (05:27) Clinical researchers at Hannover Medical School (MHH) have succeeded for the first time in stopping the usually fatal course of pulmonary hypertension thanks to a novel therapeutic approach. Pulmonary hypertension is a type of high blood pressure that affects the arteries in the lungs and the right side of the heart. Pulmonary arterial hypertension (PAH), blood vessels in the lungs are narrowed, blocked or destroyed. In some people, pulmonary hypertension slowly gets worse and can be life-threatening. A three-year-old girl suffering from so-called pulmonary arterial hypertension (PAH) was treated a total of five times with mesenchymal stem cell products obtained from a human umbilical cord. The researchers' analysis showed that the products of the stem cells from the umbilical cord were able to improve regeneration in the damaged blood vessels, inhibit inflammation of the blood vessels and curb damage to certain parts of the cells. Professor Dr. Georg Hansmann, head of the Translational Cardiopulmonary Biomedicine research group, talked on the treatment’s success:“The treatment led to a significant improvement in growth, exercise tolerance and clinical cardiovascular variables and reduced the number of plasma markers in the blood that can be detected in vascular constriction and inflammation." After six months, not only was there a clear improvement in health, but there were also no undesirable side effects.First time there is a therapy for people suffering from pronounced forms of pulmonary hypertension The team assumes that such a therapy must be repeated at regular intervals in order to be successful long term, in the case of chronically progressive, often therapy-resistant pulmonary arterial hypertension (PAH). Japan Is Dropping a Gargantuan Turbine Into The Ocean to Harness 'Limitless' Energy | ScienceAlert (08:53) Japanese engineers have constructed a true leviathan, a beast capable of withstanding the strongest of ocean currents to transform its flow into a virtually limitless supply of electricity.IHI Corporation – has been tinkering with the technology for over a decade now, partnering with New Energy and Industrial Technology Development Organization (NEDO) in 2017 to put their designs to the test. In February, the project passed a major miles
