| Would a fusion reactor be affected by earthquakes? Posted: 10 Apr 2018 02:50 AM PDT I couldn't find any sources on which effect earthquakes would have on a reactor. Obviously, the structure could be ruined by a high magnitude, but i was wondering if smaller ones would have any effect on either the safety or efficiency. [link] [comments]  |

| Posted: 10 Apr 2018 07:00 AM PDT This is a video that was posted in /r/whoahdude. https://i.imgur.com/d3hLJFQ.gifv Why does the potential equalize between the helicopter and the power line? Shouldn't, with every flip of the phase, a new potential difference rise between the helicopter and the power line, keeping a permanent, 50 or 60Hz alternating current flowing between the two?

| What does a 392 MW capacity in a solar plant mean? Posted: 09 Apr 2018 11:24 PM PDT According to https://en.wikipedia.org/wiki/Ivanpah_Solar_Power_Facility it says The plant has a gross capacity of 392 megawatts what does that mean. does it mean it generate 392 power in year or day ?

| How close to a perfect vacuum is space? How do satellite radiators work? Posted: 09 Apr 2018 04:35 PM PDT I've continuously heard space is not a perfect vacuum, however how good of a vacuum is it? Context and additional questions: I'm in a course dealing with geostationary satellites. Their heat rejection mechanism is a set of simple radiators. I asked if space is a vacuum how would the radiators work. I thought the point of a radiator was to expose the heat to a fluid to carry it away. How exactly would that work in a vacuum or near vacuum? The only answer I received was space is not a perfect vacuum. For reference if it makes a difference geostationary satellites are 35,786 km above the equator. [link] [comments]  |

| Posted: 10 Apr 2018 01:30 AM PDT Fallout is a great example of what I'm talking about. For example, in Fallout 3, the sky is a permanent greenish yellow colour because of background radiation, and the water is green too. Highly radioactive objects and creatures also often glow this greenish yellow colour. In real life, I know radiation has no odour or taste and is invisible, but can gamma radiation actually make objects appear greenish yellow or even glow? [link] [comments]  |
