Translation Clip "a" : S: The most beautiful parks of this campus are behind these walls, on each side of this road. They are covering a large drain system for filtering the waste water coming from the population and equipment of this campus. Do you know that? S: Yes, Professor! Clip "b" : S: Inside this testing tower, there is a tall and huge confinement room within which we can create the vacuum and cryogenic conditions of the outer space. It has 10 meters in diameter and 100 meters tall. S: I am seeing a chimney above the dome that covers this test tour. Clip "c" : S: This ionic chimney, it looks so short. Is it really able to let out the exhaust propulsion ions, without letting in the ambient air? S: Yes, Ionivka, but it can be used only once during a test. We have to replace its internal mechanism after each test; it takes 3 days to replace it. During a propulsion engine test, you may increase its propulsive force gradually, but you may not reduce it; you may only stop the propulsion suddenly. This chimney will close itself within 0,1 sec. Clip "d" : S: This is huge! Clip "e" : S: Within this huge white dome, beyond that truck, there is a cylindrical shape containment room, providing the vacuum and cryogenic conditions, like the one of the test tower. Within this room, there is a small HeLiPReFNu-P that I made it delivered here, 2 years ago. We will test that containment room in 2 days. Then, you will have to resolve a serious stability problem of this reactor when it is operated beyond 20% of its capacity. The larger fusion reactor of Dr. Wong has the same problem. ... That truck is delivering liquid hydrogen for the purpose of reaching cryogenic temperature within the containment rooms. Oh! I am seeing the administrator who is coming out of the office and walking towards us. S: Professor! Clip "f" : S: Here is Bianca Della Cyrano, she is the administrator of this area. You should always get her approval before coming here. The reason is for avoiding accidents with various machinery here. There is also a doctor, in the office of this site. You understand, Ionivka? S: Yes, Professor. Hi, Ms. Della Cyrano. S: Welcome, Ionivka! I have heard about you.
