| What happens to electricity pushed onto a grid beyond that grid's capacity to use it? Posted: 13 May 2017 06:00 PM PDT With the ascendancy of renewable or otherwise privately generated electricity, many electric companies allow electricity produced in excess of private use to be 'pushed' back onto the wider grid, even paying for that generated electricity in many cases. It makes sense to me that, most connected users being net-electricity-consumers, whatever electricity I push onto the grid is just used by someone else connected to the grid. My question is, what happens once private generation exceeds grid usage? Where does 'unused' electricity go? What method or mechanism is used to shed excess energy in an electrical grid?

| Could dark matter be explained by neutrinos? Posted: 13 May 2017 08:49 PM PDT Okay, there has to be a gap in my knowledge. Which, as an armchair science enthusiast, does have many such gaps. But here's my thinking, and please let me know where I've gone wrong. 1: Dark matter interacts gravitationally, but not with the electromagnetic force. 2: Neutrinos have mass, but don't interact with matter. The only way we can detect them is when they break light speed through a material. I was also under the impression that they wouldn't interact electromagnetically, since they don't have electrons to absorb/emit photons. 3: So, if we have a bunch of neutrinos, maybe even slow-moving (is that even possible?), would they exhibit the characteristics of dark matter?

| How do you clean up a natural body of water? Posted: 13 May 2017 04:21 PM PDT This is something that's always perplexed me. Once you stop the dumping, what comes next? Does the surrounding land cleanse the water? Are there chemicals and filtration processes that clean the water? How do you clean the water without destroying the ecosystems within?

| Posted: 14 May 2017 01:08 AM PDT I'm aware of lenticular clouds that easily form above mountains, but are there areas in the world where you couldn't see typical clouds like this or any clouds at all? [link] [comments]  |

| Does leaving the A/C on waste less energy than turning it on and off? Posted: 13 May 2017 09:57 PM PDT I live in a very hot city (like 90+ degrees hot), and my apartment uses central air conditioning. Someone told me it's less wasteful to keep the AC on at a reasonable temperature (around 70), than turning it on at night and then off during the day. Supposedly the energy it takes to bring down the temperature from 90 to 70 is higher than just keeping it at a constant 70 throughout the day. Is this true? [link] [comments]  |
| Are blood transfusions ever necessary to save a life? Posted: 13 May 2017 05:47 PM PDT That might sound absurd, I know, but that's where I found myself yesterday. My wife's family are Jehovah's Witnesses and a new mother was explaining how she will refuse blood for her kid no matter what. Their reasoning wasn't that their religious beliefs trump the medical necessity, but rather, that there isn't actually any medical necessity. They have convinced themselves through their own "research" that there is never, in fact, a need to have a transfusion, in any circumstance. I said what about a gunshot wound where the kid is bleeding out? Nope, apparently transfused blood doesn't even "work" for 24 hours so obviously it's not a critical intervention. I'm honestly frustrated and baffled at this kind of thinking, maybe more so because they're claiming to base their thinking on science when as far as I can tell that couldn't be further from the truth. But they did repeatedly point out that I'm not a doctor, so, I'm curious how others, maybe even medical professionals, would respond. [link] [comments]  |

| Posted: 13 May 2017 04:47 PM PDT My curiosity was peaked by this r/earthporn post. It seems amazing that such vertical cliffs have such deep 'bites' taken out of them. And there's clearly a periodic nature to the repetitive pattern. I'm an earth science novice, but I was wondering 1) what is the underlying current that causes this and 2) is this caused mainly by water erosion, or does the wind play a significant role? Thanks [link] [comments]  |
| Posted: 13 May 2017 04:10 PM PDT My country is in the process of implementing laws to allow law enforcement to essentially do random breathalyzer tests. I'm curious if this will result in a significant increase in false positives since the population they will be testing will have a much lower probability of being impaired. [link] [comments]  |

| How can the body organize and transport different nutrients and vitamins, while flushing out waste? Posted: 13 May 2017 01:33 PM PDT How does the digestive system recognize that riboflavin is going to A and potassium is going to B while proteins go to C, transport them to the appropriate locations and dump the waste?
