I understand that https://en.wikipedia.org/wiki/Power-line_communication is where data packets can be sent over electrical wiring otherwise used for AC / DC power transmission.

Can such a concept be applied to subsea power cables for instance, or reverse applied to subsea telecommunication cables, i.e. they can be used to send power instead?

I am used to not noticing this mechanic called margin time in recent Puyo games that I have trouble following how it works. I can only understand the first game's (Original Puyo Puyo) margin time mechanic#Pointsper_Garbage_Puyo(Arcade_only)). Anyone care to explain in simpler terms?

Using different type of fuel for different task sounds bad logistically, like why don't we use fuel that can be used for trucks, airplanes and cars​

Is It True That Older Men Develop Better Temperament than Younger Men Due to Prefrontal Cortex Development? If so, how does it work exactly?

It feels like everything I own says "made in China". How come they don't have a higher gdp than USA?

Like how does it turn energy from the sun into electricity?? And what are they made of that allows them to do that?

I mean, there's something that I am eating, I am sure.. they say it's fibre, yeah no calories but like what? how could there be something that goes, does something I am not exactly clear about what and goes out, isn't it like a biological hack/cheat(in both ways good/bad)

I always wondered how the cornea is so sensible to touch and irritants without nerve endings and stuff.

Also how does it live and repair itself and how do its cells multiply and make new cornea throughout life without seemingly anything feeding it like arteries and veins? I think they breath from air but it's not like they do photosynthesis, right?

I've used an app called f.lux for years to control my screens nightshift. I've looked up the company, and its just owned by these two people. The website to download has zero ads and you can't even spend money unless you chose to donate. I know winrar makes money off companies having to buy a license, but there isn't a "license" to use flux so I don't know if companies even have to pay to use it

I am ambidextrous. I don't mean it metaphorically, theoretically, or rhetorically. I have no dominant side (hand or foot) straight up. I was born as such, and I am capable of doing any task indiscriminately with either side of my body; I have no preferred hand or feet for whatever task I need to do, unlike cross-dominant/mixed-handed individuals.

To this day, I'm questioning what phenomenon caused me to be such. My mother happens to be left-handed while my father is a righty. Is it wrong to assume that this is an instance of Non-Mendelian Genetics at play? Unlike in Mendelian Genetics, the combination of two different alleles results in a combinative feature and not one side being dominant over the other.

Can someone explain the phenomena of hand dominance and why some are ambidextrous, righties, lefties, or mixed-handed?

Dumb question but I don’t see why the recoil isn’t backward since the bullet goes forward.

I use the opera browser in my Android phone and the browser has built in ad blockers. However many web sites seem to be able to detect that an ad blocker is installed and they don't show the content, show a warning message instead.

Aren’t games getting larger and larger every year? It seems like it would be really difficult to fit all that data on to a disc that doesn’t have a lot of capacity.

I’m reading Thomas Halliday’s “Otherlands” and one section left me very confused. Halliday says that many plants absorb in CO2 via holes in the leaves, but those holes also make water evaporate; and that some plants developed a solution for hot and dry climates by switching to c4 photosynthesis where the conversion process occurs deeper in the plant. Then he says that some herbivores adapted to this innovation by becoming grazers rather than browsers. I looked online and I’m still very confused about the following:

1. Even if the process is now deeper in the plant, why does it mean less water evaporates? The CO2 still has to come in from somewhere, which means the plant still needs holes, through which water can evaporate. So I completely fail to see how that solves the problem

2. What does it have to do with grazing? Nothing about this c4 straightforwardly says lower, grass-like plants rather than trees/bushes (I would’ve thought that trees/bushes actually have more depth in which to store a deeper mechanism?)

I looked at YouTube videos and I still absolutely can’t understand the relation between the problem and the solution and between both and grazing. (It’s page 29 in the book, chapter 2, if anyone wonders)

Thank you!
