| Posted: 12 May 2017 09:00 AM PDT Doing research on buying electricity from a 100% renewable source supplier (via REC) in my state and came across this note(two studies linked): https://en.wikipedia.org/wiki/Renewable_Energy_Certificate_(United_States)#Additionality
This seems to indicate that a decision to choose a supplier with 100% renewables may not have any meaningful market impact, and may simply be a "feel good" purchasing choice. Is this a problem of scale, with not enough homeowners voluntarily opting to purchase from renewable suppliers? [link] [comments]  |
| Posted: 12 May 2017 06:43 PM PDT I know theres ocean currents, but are there smaller more localized temporary occurrences underwater? Obviously precipitation is out, but are there any sort of weather events? Strange eddies or localized currents where warmer and colder waters meet, the equivalent of a a windy stormy day under water? Are there ever the equivalent of dust storms along the ocean floor? Anything that could reasonably be called weather? [link] [comments]  |

| How do relativistic effects impact fast rotating pulsars? Posted: 12 May 2017 08:16 AM PDT Some pulsars, like PSR J1748-2446ad are rotating at almost 25% the speed of light. Given that the object is only 16km across that means there is a huge differential between the seed of the core, and the speed of the surface of the pulsar. In what ways do time dilation, frame dragging, and other relativistic effects impact the pulsar and its behavior? [link] [comments]  |

| Why does a rapidly spinning ellipsoid turn vertical? Posted: 12 May 2017 05:32 PM PDT Based off this video. Initially the ellipsoid is spinning in an orientation that we'll call 'horizontal'. Then it 'flips' and starts spinning in a 'vertical' orientation. My understanding is that objects tend towards a ground state of lowest energy. So why is the vertical orientation one of lower energy at that particular moment? Is that even the right question? What's going on here? Basically my question is this. What causes the ellipsoid to flip like that? Additionally, why does the vertical orientation appear to be more stable? [link] [comments]  |
| How does AI work if computers can only do what they are programmed to do? Posted: 12 May 2017 03:57 PM PDT I don't really understand AI. How can a computer or something like it learn when the only thing they can do is what they are programmed to do? Wouldn't all the learning be expected by the person that programmed it? Can the AI really do thinking? [link] [comments]  |
| What is the difference between human and fish blood? Posted: 12 May 2017 04:09 PM PDT At first I wondered if fish have blood like we do. They do, at least it's red (unlike insects). But when I looked at the images google gave me I noticed that their blood cells look different. Fish blood (Rainbow Trout) seems to have nuclei in their red blood cells. Whereas human blood does not. Are there any other differences between human and fish blood? And what is the purpose of these differences? [link] [comments]  |

| Is there a best shape for a radiator in space? Posted: 12 May 2017 11:37 PM PDT If you have an object in space that is generating heat and need to cool it, is there a general rule for the shaping of the radiator? For instance, if the cooling element is shaped like a traditional air cooled radiator, will it be less efficient due heat transfer to other fins on the radiator? Or is there another element of radiation heat transfer that produces a net benefit for more surface area in a set volume? Thanks! [link] [comments]  |
| What was the speed of glacial retreat prior to the 1900's? Posted: 12 May 2017 07:50 PM PDT I got into a discussion about climate change with a friend, and hes skeptical about the recent speed of glacial retreat being faster than the retreat prior to modern tracking methods. Is there information about glacial retreat speeds prior to the 1900's? Thanks! [link] [comments]  |

| How does altitude affect plant growth in plants that have specific altitude requirements? Posted: 12 May 2017 04:16 PM PDT Take coffee for instance, it doesn't NEED altitude but is definitely limited by it. Is there a property of altitude other than temperature and day length that I don't know about? [link] [comments]  |

| Can nuclear weapons be made of fissile material other than U-235 or P-239? Posted: 12 May 2017 01:46 PM PDT If so, has this been attempted and were there any tests? Are there any advantages or disadvantages? [link] [comments]  |
| Why is there no radiative correction to the photon or gluon mass? Posted: 12 May 2017 12:21 PM PDT Radiative corrections add to the bare mass of particles. This is often illustrated with feynmann diagrams involving loops. I can also think of loop diagrams for a photon flying around. So why do we not observe a correction to its mass? [link] [comments]  |
| What would terminal velocity have been in dinosaur times? Posted: 12 May 2017 11:16 AM PDT "Dinosaur times" is stupid vague, I know. I'm sorry. But it covers millions of years and I don't have a specific time period I'm asking about. Just the idea that when there was more oxygen in the air to support huge mosquitoes, the air must have been thicker, right? Therefore increasing friction and decreasing falling velocity. But I was curious what the difference was, whether it was an appreciable amount or not. [link] [comments]  |
| Posted: 12 May 2017 01:02 PM PDT We've heard of planets where it would rain liquid methane or liquid iron, i was wondering could it be possible to have full oceans of methane on a planet and so just like on earth where there would be a cycle that transfers water from oceans to moutain tops ? Could it be possible or is this just a property of water ? [link] [comments]  |
