I'm sorry, what transplants?

Woovie ,

people with certain medical issues in their bowels can be cured of them by a fecal transplant from someone who is a good donor. It usually means a family member. The purpose is to treat bowel infections. Pretty neat shit.

PrettyFlyForAFatGuy ,

neat shit

Actually i think it's usually pretty diluted

ReeferPirate ,

South park aired an episode about it with a Dune twist.

Still the best adaptation.

barsoap ,

It's about the microbiome, lots of critters living in your bowels breaking down stuff for you. Some conditions or treatments (e.g. chemo) can fuck with that severely up to completely obliterate everything so you need a donor to get it started up again.

rekabis ,

Most of your body’s mass does not have a human genome, it represents other living things existing in symbiosis with your body. And your digestive tract is nearly 100% reliant on these microbiota to break down food and provide it to the small intestine. If you don’t have the right mix/balance or you have too many of the wrong species, you can suffer extremely deleterious health effects. If you have none at all, you starve pretty quickly regardless of how much food you eat.

Fun facts:

  1. Almost all of your excrement that isn’t visible remnants of unchewed food are the remains of gut bacteria that died.
  2. Scientists have recently confirmed that your appendix acts as a “safe room” for your good, beneficial gut biome to retreat to when the rest of the intestinal tract is suffering from catastrophic environmental issues or another bug is running rampant and dominating in a destructive manner. Once things calm down, the intestines are re-colonized by good bacteria from the appendix.

Not enough power. A car is not a 1500 watt appliance.

Wasn't really a car, though, rather

a small one-person battery electric recumbent tricycle, technically an "electrically assisted pedal cycle".

And a micro car wouldn't be able to have even a 750 watt panel on it.

It's way more effective to collect the solar energy from a station to charge batteries than to cary the whole thing around unless your car is a drone on some remote planet

unless your car is a drone on some remote planet

Which is about as ineffective as personal transport gets. And also not a car.

They're not—as long as the PV cells are a supplementary charging solution, in addition to wall charging, to the batteries. You'll get a bit more range out while driving, especially when the car is a lightweight low drag design and PV cells may be the only thing needed to keep the constant 90 km/h speed in a sunny day. And when not driving the cells might be enough to get the 10...20 km or so commuting range back over your 8-hour workday.

But putting PV cells on a 3 ton electric SUV or pickup truck is stupid, it won't do jack all due to the inherent inefficiency of such vehicles.

biddy ,

Let's worry about the inefficiency of SUVs and pickup trucks for transporting one person to work. Compared to that solar panels are a drop in the bucket.

rtxn ,

Solar cells of comparable scale don't provide nearly enough power to propel any kind of useful mass, and their output is only a trickle compared to even the slow-charging current of a classical EV. A solar-powered car would have to save mass everywhere, including safety devices (goodbye, crumple zones), backup propulsion, and batteries. No batteries means that the car would be limited by weather, time of day, and day of the year (winter -> sun at lower angle -> reduced solar cell power). Solar cells would have to be flush with the car's body lest they turn into sails/wings/airbrakes, which makes tracking the sun for better efficiency impossible. Driving through a city, a wooded area, or inside a tunnel would cast shadows on the car, especially at dawn/dusk.

I could go on.

frezik ,

The sun gives you around 1500W per m2. If sun shines at maximum brightness for 24 hours, you get 36kwh per day. That's enough to fully charge a small EV every day. That's a spherical chicken estimate.

Bringing this to numbers that exist in the real world, the sun will only give you about 20% of that over the course of the day, and the panels are around 20% efficient. You'll get more like 1.4kwh per day per m2. You can double or triple that, depending on how much surface area you can cover. An EV can get around 3 miles per kwh, so tripling that number will get you 12 miles. Considering the extra costs involved (both in buying the panels and adding weight), it's not even worth it as a supplementary source.

There's some possibilities for RVs, which have a lot of roof space for panels, tend to sit in one spot for days or weeks, and have other power usages that are a lot less than driving. Otherwise, put the solar panels over the parking places and roadways, not on the cars.

jmiller ,

The benefits increase as the efficiency of the car increases though, check out Aptera. They say they get 10 miles per kwh, and they have a lot of surface area for panels. Enough that in ideal conditions they say they get 40 miles per day from solar. It is a bit different looking though.

frezik ,

It's also a three-wheeler, which gets around US safety regulations. It gets registered as a motorcycle or autocycle (depending on how your state handles it). However, it's still an enclosed metal box. There's not a lot of good data, but it's arguably better to be sitting loose on a motorcycle with a helmet and safety gear as opposed to being crushed inside a sardine can.

There's a certain point of shrinking cars where you have to ask "why not use an e-bike?", and this is that point.

Fenrisulfir ,

Cuz you can haul more, camp inside of it with the tent mod, travel further and faster.

They’re planning 250, 400 and 1000 mile versions. I’m also not taking an e-bike on the highway.

frezik ,

I'm not sure you can haul more. Cargo e-bikes can do a lot more than you think.

Fenrisulfir ,

Ya I saw that cybertruck to cargo bike comparison. I automatically went to the mountain bikes. We don’t have the same cargo bikes the Dutch have but there is a guy around here with a cargo e-trike. I bet it’d be close. But the car can also take a second passenger not in the cargo space.

jmiller ,

Well, it has a carbon fiber frame with a crumple zone in the front. They are going to put it through 3rd party safety testing. It won't be as safe as a big SUV, sure, but I think it will be safer than an ebike. It also protects you from weather and has 35 cubic feet of storage in the back. I think ebikes are great too, but this does have more of the advantages of a car.

frezik ,

You know how the Internet made fun of Stockton Rush for using carbon fiber in a sub, which is a compression structure? Similar thing going on here. Carbon fiber is a great material for tensile strength and lightweight. It can be used in compression structures, but it needs more careful engineering to pull it off. The benefits do not always outweigh the costs.

As a more general issue, if a car the size of a Geo Metro or smaller can't be safe on roads, then motorcycles and bikes can't be, either.

jmiller ,

Well, I just said carbon fiber, but to be more exact it is forged carbon SMC, so yeah, careful engineering involved. Same stuff Lamborghini is using for some structural components, so probably fairly fit to purpose.

zeekaran ,

The energy one can get from a panel the size of a car roof is tiny and not worth the added weight.

daltotron ,

They're not. If you make your car light enough, and potentially aerodynamic enough (things which should already be done to electric cars/cars in general), it makes sense, especially for the real life practical application of people who don't have outlets they can run to their car. Aerodynamics is mostly just an efficiency increase, but decreasing weight gives a myriad of benefits, potentially including increased power to weight ratio, decreased road wear, decreased road noise at speed, increased efficiency, improved crash safety as a result of decreasing the total amount of weight you have to stop, which can actually improve the efficiency of the interior space as you can now make things like roof pillars less thick. Could also lead to increased parking space, better maneuverability, and better visibility, if you make the car itself smaller as a result of decreased weight.

Cars should be like1/3rd of their current size. Clown cars ftw.

rekabis ,

I… am strangely ambivalent and conflicted about soup.

I recognize logically and rationally that it should be lower or to the left, but would personally place it higher or to the right.

Maybe smack dab in the centre gives us the worst of both options.

mightyfoolish ,

If anyone else is also curious on why "putting mold on infections" is more good than crumple zones:

They [molds] also play important roles in biotechnology and food science in the production of various pigments, foods, beverages, antibiotics, pharmaceuticals and enzymes. - Wikipedia

grue ,

My beef with the placement of that item is that it isn't even further down the "actually a good idea" axis. Penicillin -- perhaps the most important medical innovation of the 20^th^ century -- rated less "actually good" than mere laser eye surgery and fecal transplants?! C'mon, Randall!

refalo ,

Yesterday I heard a conspiracy theory that the reason lead was added to gasoline was to keep the Pouge carburetor from becoming viable because it allegedly used pre-heated gas vapor to achieve 100-200mpg efficiency, but the lead clogged it up instead.

Here's my own counter-conspiracy on that... if everything we read says that it didn't actually work, why did Breen Motor Company claim it worked when THEY tried it? And why did Pouge suddenly disappear?

EnderMB ,

Hmm, I had never thought of it...but soup is absolutely a neutral experience. Even a good soup on a cold, winter day is still slightly above neutral, and is improved by non-soup add-ins.

Maggots on wounds is a thing too. They only eat dead tissue

EmoDuck ,

Wouldn't maggot poo or the eventual maggot corpses cause problems?

leftzero ,

Not as much as necrotic tissue still attached to the patient, I suppose.
(The idea is that these maggots are extremely good at debridement, that is, at eating only the dead tissue and leaving the still healthy ones alone; other methods, like scalpels, can't be so discriminating, and force the doctors to remove healthy tissue to make sure there's no necrosis left).

SomeAmateur ,

The maggots do the hard work cleaning the wound. Cleaning up the maggots and poo is easy by comparison. But yeah you don't want to leave them there forever, just enough to remove the dead stuff.

Why not? I thought they were pretty popular.

grrgyle ,
@grrgyle@slrpnk.net avatar

I don't know. I think it's because they're practical?

Spur4383 ,

It's because they are not practical. They do not work inside cars, they transition super slow in winter, they are clear when you need sun glasses and dark when you need to see.

captain_aggravated ,
@captain_aggravated@sh.itjust.works avatar

They worked pretty well when I was in high school marching band. I didn't drive yet so I didn't need road vision, they darkened while out at practice and were clear elsewhen. Got an actual pair of prescription sunglasses in flight school though.

BearOfaTime ,

They transition just fine in winter, even down to 10f or lower.

They have a version that works in cars now. But that's an issue with the car windshield blocking UV. So leave a magnetic "clip on" shades in the car. They look exactly like your frames, with them attached you can't tell they just stick on from the front - they look just like your glasses.

Crozekiel ,

Then just use the clip-ons all the time and not pay for mediocre sunglasses? I'm not a fan, I've tried them and hated them. Super slow to go back to clear and unreliable. I don't want my lenses deciding when I need tinted lenses or not when I can just carry around either clip-ons or a complete second pair of prescription sunglasses. IMO Transitions are a bad solution to the problem.

BearOfaTime , (edited )

Because I don't have to carry the sunglasses with me all the time?

98% of my time I'm not in a car, and my not mediocre sunglasses work better than the clipons, since I prefer the color, they already block UV and aren't too dark.

Why should I carry something else?

As it is, I put my glasses on when I wake up, and most days only take them off to clean them or go to bed. They're almost hassle free, unlike carrying around sunglasses, putting them on, taking them off, yada yada , like I did for 10 years before I got transitions.

Why do you carry a smartphone, instead of a laptop, tablet, feature phone, GPS, mobile access point, multiple credit cards, rolodex, checkbook, etc?

It's funny you trying to tell me that I'm wrong to choose what works for me.

Crozekiel ,

Calm down and quit shilling for "big-transitions".

limelight79 ,

Yeah, I've used mine while cycling in freezing temperatures without an issue.

Takumidesh ,

So the scenario is
A) you have transitions that work 90% of the time and a pair of prescription sunglasses for the times they don't
Or
B) you have regular glasses, and still have prescription sunglasses.

Option a means 90% of the time you don't need to carry an additional pair of glasses with you.

I used transition lenses for a decade, they are great.

You know, we're generalising, but you've got a point. None of my male friends have glasses in any kinds of shapes other than "boring grey ovoid."

Obi ,
@Obi@sopuli.xyz avatar

I have to wear them every day with any outfit at any occasion, it sounds silly to choose something flashy.

EncryptKeeper ,

It’s not the shape, it’s just the transitions themselves. Aesthetically, sunglasses have a handful of popular styles. Whatever frames you have for your regular vision correction, most likely aren’t one of those styles.

Spur4383 ,

They work based on UV light. So they will not transition inside cars. They also will not transition in cold weather, so you'll walk in snow with clear glasses and have dark ones for 5 minutes once you go inside.

BearOfaTime ,

Never had them not work in cold. They change even during heavy snowfall when it's well below freezing and well, no sun, heavy clouds. It's great because they help with the glare from snow.
