I don't have (nor do I intend to obtain) a VR system, but why do they all seem to default to clunky controllers instead of something like a power glove?

I think I've seen some "glove" interfaces, but why isn't that standard?

[Egan_BW]

The index is glove like. Think that's what it's named for actually.

Other ones are probably glorified wiimotes because that's what's easier to make most likely.

Welcome to the future

Valve index is the same kinda shape, and when I use my VR headset I keep wondering how one would move the other fingers... it's allready not allways easy to keep a grip on the controller in every imaginable scenario, while using only the 3 main fingers.

The thing you want most of all are analog joystick below each thumb, actually,  I only have an issue with those crunchy awful d-pads on htc controllers.

Glorified wii motes? In the sense that wii had 1 puny IR reference point for the controller fixed on top of your tv, whereas the WORST VR tracking is 4-5 IR cameras (big difference allready, them being cameras), but there is also tracking with color cams, and at the high end you can get lighthouse trackers, so reference points again but way fancy, not sure if they have cams or lidar or what.





All I can advise is prioritize getting a headset with a real display port / HDMI connection if you want to get into VR. The only standalone that I know of that has both standalone capabilities and a real (uncompressed) video-in is the pico neo link 3, it's what I bought, quality is ok, price is great but the FOV isn't great.

Under what conditions would ethanol be likely to degrade into methanol? Is there such a thing, or can methanol only happen at the initial distillation?

[Il Palazzo]

Afaik you can only get one from the other through a series of reactions with other, rather nasty, chemicals.

How reassuring, I'm an idiot when it comes to chemistry so I can only qualify it in these simple terms: man ethanol is such a tough and neat molecule.

I guess it would make sense since it can be used as sort of a preservant.

Ay yai yai, step 2 and we're already pulling out the osmium tetroxide. I think we can do better and cheaper.

To make methanol from ethanol we need to cleave a C-C bond which is a somewhat unusual transformation to do (usually, we're trying to form them). We could make ethene first as they said, but then do an ozonolysis (using ozone of course), to form a molozonide, then add some sodium borohydride to form two equivalents of methanol. These are all cheap reagents. The ozone you'd have to make by passing a stream of pure oxygen gas from a canister through a spark plug.

If you put air in an opaque jar, does that count as CO2 sequestration?

How "de-coupled" from the atmosphere does it need to be to make a difference?

[Egan_BW]

I mean, you're trapping the nitrogen and O2 and such as well, so the action doesn't decrease the overall concentration of CO2 in the atmosphere. I guess if you made sure to exhale into airless ziplock bags which you then seal, it would be sequestration.

[scriver]

Are you pondering a COČ sequestration scam, traveller? Because if so I am totally in.

[Il Palazzo]

I mean, you're trapping the nitrogen and O2 and such as well, so the action doesn't decrease the overall concentration of CO2 in the atmosphere. I guess if you made sure to exhale into airless ziplock bags which you then seal, it would be sequestration.

While the concentration doesn't change, the overall amount of CO2 available for interaction with radiation goes down. And it's the latter that matters for the strength of the greenhouse effect. The more molecules in the atmosphere, the more chances the outgoing radiation will interact with one or more on the way.
For illustration, if the entire atmosphere save for one jarful were so sequestered, the remainder would be causing negligible change in equilibrium temperature, even though the concentration would stay the same.

[Egan_BW]

So digging dark holes in the earth so that less of the atmosphere is exposed to light actually counteracts the greenhouse effect. Always knew that dwarves were truly eco-friendly.

[McTraveller]

Yeah I mean I'm trying to figure out how much I'd have to charge "someone" to be willing to just start "capturing" air to remove CO2.

I mean "all these people" are saying they're willing to pay for sequestration, why not try to get in on that?

Of course - this isn't even touching the fact that how do you value the investment here - this is not investing in something today to "have more of something" in the future, this is spending money today so that we "don't suffer the effects of something" in the future.  The latter is particularly difficult because the actual future cost is unknowable so it's hard to even do a discount model - at least for an individual basis.  I mean sure you could say "I totally lose everything I own" but how do you price that per ton of CO2 or whatever?

Note I don't mean "how do the goofy legislators or carbon markets price it" because those aren't based in reality so much as they are based on emotion and agenda.

I was reading about a start up company that was pumping anti-greenhouse gases into atmosphere.
