Imagine being awake, trapped inside your body for 15 years... There's no coming back from that... Poor guy. I'm happy he gets the chance, but that is going to be one rough trip.
Yeah imagine waking up from that. You'll probably know nobody, and people who remembered you would know you as "that unconscious guy." I wonder if it felt like 15 years, or if it felt like just waking up from a nap. The whole world would be so different too... it would be cool to have a interview with him.
I hope he does an interview about his experience if he ever fully recovers.
The interview will be him asking more questions than answering any.
Descending that reminds me of "One" from Metallica, trapped inside your own body (i know the guy in one it is not in vegetative state, still...)
In before science proves the existence of a "soul" which left the guy long ago. Wouldn't that be insane?
I have a friend from Idaho, which is best known for growing potatoes. He grew up in a Vegetative State.
Master Therion you should be on stage, man.
and yet, he's not a vegetable :3
Such a beautiful Jewish story.
I live in Idaho and I can confirm that fact. (we grow 100 lb for ourselves every year)
that. was. marvelous. *light claps*
Unresponsive but awake for 15 years? You'd think that poor guy would be absolutely insane by now. I don't think I could imagine something worse than being trapped in your own body like that.
OneColdMonkey Judging by how he acts after being treated, he was probably not very capable of concious thought while unresponsive, so it probably would've felt more like... nothingness. You can't really go insane if your thoughts are inactive.
But now they are making him aware, whilst there remains no chance whatsoever of him getting up and having a fulfilling life. If he is awake to a reasonable degree, he is now being tortured by his imprisonment in his broken brain. Douchebag researchers in this case.
He might just be a semi conscious state. There's no way we can know without hearing it from the man itself.
But he wasn't that kind of responsive, ie the brain isn't working properly at all. It's not like you're still in your full mind when your brain isn't active, you're basically dead at that point. However if they start firing up the brain and actually get it to "work" but he's still stuck in bed without any control or real way to communicate - that would drive him insane. It's pretty sad to think about it, if they can start waking people up... it means that the doctors have been murdering people for a very long time.
Correctrix Well no, it's not like he's unable to move and his brain functions are normal. He can move fine, his brain doesn't function. He has consciousness, like a newborn baby or an animal, that doesn't quite mean he's capable of complex thought. He more than likely doesn't even remember what he was like. He's conscious but not necessarily self aware.
Awake and unresponsive? I've come across many people like that. LOL
electronicsNmore everyday, bro

I really like this narrator. He kills it with crash course philosophy too. Very interesting ideas.
These kind of new innovative power sources make me hopeful for the future :)
This is great! I've always thought that it was impossible to bring people back from vegetative states. Truly, this could be the start of something amazing.
Holy cow. I’ve recently been researching about persistent vegetative state and then this appeared. There was actually a case where a woman was giving her son ambien sleeping medication to her vegetative son and somehow that would activate or arouse parts of his brain that were initially inactive before. After 5 years, he’s been able to respond or be aware of his surroundings after several therapy sessions. This was on another video I watched. I’ve also read articles on using medication that was for Parkinson’s disease to create a similar effect. I think this is great that they’re finding solutions for this.
this is so exciting! i love how science continues to advance
I really need to write a living will, it will include something like this: "If I'm ever in a vegetative state for more than a month then please try anything, from electroshock to lap dances from attractive women, start with the lap dances."
And now for the serious part of the comment (I can be serious once in a while):
About using the water cycle, if you use the energy used by evaporation then doesn't that prevent or diminish the evaporation? If you do so to provide enough energy to be noticeable in an energy voracious country like the U.S.A. then doesn't that risk affecting the weather?
I hope this will be used to give conscience to cucumbers, pineapples and other veggies too! 🌵
Please don't! What am I gonna eat then? (Vegan)
L Galicki Band Pickle Rick!!!!!
pineapples are fruit...
Cucumbers are fruits, they have seeds
What even is a vegetable? (Botanical definition of a vegetable, please?)
Hey. That's pretty good
Best episode in a while. Nice job
The "evaporation engine" is certainly a cool idea from a scientific perspective, but I'm highly skeptical that it could ever be a viable source of large-scale energy. How could you possibly collect enough evaporation to do anything useful in an economic fashion? From a "physical footprint vs power produced" standpoint alone, I'd have to think that solar and wind are both orders of magnitude better. I'd like to see someone run the math, though.
My money's still on a combination solar, nuclear fission, and (eventually) nuclear fusion as our best bets to move away from CO2-producing energy sources.
Victor Smith What about tidal and wind? Also geothermal to heat homes
I agree. Just use nuclear, and launch all the waste to mars.
Yeah, and while he pointed out water chemistry issues associated with possible collectors, if you put something over the water that will affect it's evaporation rate. Also, this seems to rely on an up and down in the humidity levels, which do change but I don't know if they would naturally change at the correct rate required for this engine. The more energy you have to input into the process, the less efficient it is.
*+Wingedshadowwolf*
Forget evaporation rate, what about the ecosystem?
legacysage Yeah yeah. It totally wouldn't cost billions of dollars.
SciShow= showing how AWESOME science is!
The stimulation of the nervous system thing is amazing, and could revolutionize a whole section of medical science. I really hope it gets a *lot* more research, because it could impact a great many forms of neurological damage.
The Evaporation Engine? I expect big petroleum to strangle it in the crib, like they do every other form of alternative power generation.
Why do people in this comment section think the vegetable was thinking?
He wasn't thinking. Awake =/= thinking. The very idea is that his brain cells just don't 'click' anymore, so why do people even so much as assume that he was consciously thinking????
So he died?
Hello others On this website His brain was not completely dead. So he was not fully dead.
One in five people in vegetative states are aware and thinking so it’s possible he knows what’s going on
It's possible he could still feel emotions though depending on which parts of his brain were injured. Also, it's pretty offensive to him but mostly to his family to call a person who experienced something as awful as this a 'vegetable'
It’s interesting for one of my classes my teacher had me read a new scientific article and Analyse it each week and I read the one about that treatment! It had actually been used before, but that particular case found a non-invasive way to use it! Electrical stimulation requires inserting a probe into the body to touch the nerve and give it a direct shock, and seeing as it’s near a whole lot of really important parts of the brain you don’t really wanna mess with that! That particular case, they managed to stimulate the nerve with ultrasound waves, and see the same results as direct electrical stimulation! Ultrasound therapy can be done with no incisions and no entrance into the body, an ultrasound probe or wand is simply used above the skin over the area where the nerve is, set to a certain frequency to reach that specific nerve, and repeated multiple times over a series of weeks! It’s really incredible!
Why is a SciShow video giving me feels?
Round Pi coz knowledge
This guy makes science fun to learn again.
my grandma was in a coma from cardiac arrest then soon went into a vegetative state and with heavy hearts my family decided to take her off of life support. im so happy to see that maybe they can bring someone back from an unresponsive state, it must be such a nightmare.
Great ep guys
The original article said that they hadn't yet asked him if he was in pain. Why wouldn't that be the first thing they asked him?
Sarai Pope
Oops?
You know, because he’s a man with a family whose life he has missed the last 15 years of.
I think that the scientists were too excited to ask...
4:27 "178 megawatts of electricity a year" does not make very much sense. I would guess it's supposed to be either something measured in (mega)wattHOURS, or a yearly average (power).
Tommy Vaske , 178 megajoules per second per year...
Makes perfect nonsense :)
178 megawattyears? I hate when people use watts for anything other than power rates.
maybe he meant 178megawatts/year which would be ~1 559/terawattshours, LOL
maybe meant megajoules a year.
abdulaziz rushdi , hmm...
A megajoule per year is 0.03 Watts. Enough to dimly light a small LED.
This is amazing!
Thanks
My uncle was in a coma for one year. He is still strong and i know he really wants to survive. I was there taking good care of him but due to some complications, he died. His lungs and liver started to fail to the point where he cannot urinate anymore. It hurts me seeing him suffers more and kinda accept that he will go soon. It was hard. Until now i can't still get over it.
Wow, you really turned the derp up to 11 for the evaporation engine bit.
AMAZING!
Jesus imagine just *not being* for 15 years and being awoken. Falling asleep in 2002 and waking up in 2017.
Image that combined with somehow harnessing the energy of the rain
Sounds similar in concept to the downdraft towers potentially slated for construction in AZ. They also use evaporation to generate power, but by cooling air that then falls down the tower and turns windmills at the bottom.
“Getting.. a little moist” Oh hank, you are the perfect human
1:40 must've be pretty scary

Hello, SciShow! Do you think you could make a video explaining the current knowledge of cerebral aneurysms? I had one rupture at 19 and after learning so much about them, I would love for a bigger audience to learn of them!
phantasm1234 Ouch, that doesn't sound fun
phantasm1234
I asked your question on Patreon yesterday! I'm sure it will take some time, *If* they select it. I think they put question up for vote by the patrons (which takes a month.) But, maybe we got the ball rolling ^_^
honestly, how are you alive?
John Smith at least lol
phantasm1234 do you set up schedules for what time you need to post this comment everyday? Just asking.
i am liking the return of this Scishow news style video instead of QQ
It never went away.
Hankamania running wild today. Brother.
You've forgotten the most famous evaporation engine: the drinking bird!
Now that's cute.
One of the drawbacks to an evaporation engine is that it requires a large humidity gradient,. It would work best in hot and dry desert regions (where water is typically scarce) but would be useless in areas of high humidity (such as coastal areas where water is typically abundant). For bodies of water that can also generate hydro-power, it would be necessary to evaluate which process is more recefficient at that location, since the evaporation process would parasitically "steal" water from the hydro-turbine process.
Low-cost, high-output renewable energy source in development? That's gonna make the oil companies' hitmen a hell of a lot richer.
This guy is great at talking with his hands bro it's never to much of the same gesture and if you muted it you'd swear you still knew what hes saying
We human beings did this. Such amazements.
The first story makes me think of Victoria Arlan, who is currently on Dancing With The Stars.
Thanks for the very interesting video. I have a question. Are the spores not dying after an amount of time? I think, it is better, to invent durable, synthetical spore look-a-likes.
"A little moist" omg
ikr that cracked me up a bit
Wouldn't interfering with the evaporation of rivers and lakes and such affect our weather? If that water usually goes into the air and becomes our rain, would that not possibly be bad (though we certainly have had too much water falling this year!)
Would stimulation of the vagus nerve work in the case of Terry Ives from Stranger Things hypothetically work? She went into a wakeful vegetative state from 450 volts being sent into the temples of her head.
Isn't the interaction between cold and warm fronts what generate wind and different types of weather? If we take heat energy from warm fronts wouldn't that have a major impact on the weather?
It was not directly mentioned here, but. Could the Evaporation engine technology be deployed over a warm ocean patch of water (before it fuels, say, the next major hurricanes)? Wouldn't it be cool if in the future we control or prevent the natural catastrophe by preemptively collecting its energy? Instead, light houses or drive cars with etc.
Just a wishful thinking... I am no futurist nor scientist. :(
C. Sukapanpth The hurricane itself is a combination heat/evaporation engine that uses temperature and humidity gradients to produce mechanical energy (wind, waves, and storm surge). Warm, moist air is circulated from the ocean surface up to high altitude at the cloud top level where it cool and dries (condenses). You cannot counteract this because there is no way to neutralise or reverse the temperature/humidity gradients that naturally exist and impractical to build a competing heat/humidity engine on a large enough scale to make any difference.
bkm83442 Hey thanks. Figure it wouldn't be that simple.
Evaporation energy used for power grid -> less energy being dumped into formation of weather systems -> less hurricanes.
can some one explain how the bacteria used up the energy from evaporation?? what i have read is spores resuscitate in presence of water as enzymatic reactions kick start
Can the evaporators be put on top of ocean water? - that way the volume of power could increase and maybe have less impact on any eco-system. Or would it cause problems to the bacteria?
Can you believe his family kept him alive for 15 years?? Holy crap. That’s love
As opposed to what? Shooting him in the head? He was in a vegetative state, he wasn't on life support.
CJayin TV nah i think he would be netter of dead, he wasnt consious in 15 years and now he is still not consious for 95%. Thats not really a life i would be better off dead
What about injecting stem cells where the damaged area is? It worked for the clinical trials from Stanford for stroke patients, could it work for vegetative states?
Am I the only one that dislikes the 2-topic videos? The title and thumbnail only show one of them. So if I remember an old SciShow video that I want to rewatch due to a specific topic I must hope it is the main topic of the 2-topic videos, otherwise it's a pain in the ass to find them
My biggest pet peeve.
Yeah, I usually don't have any interest in the 2nd topic either.
So annoying!
Or just put the videos you find interesting in a playlist of yours...
By the time the second topic begins, I am reading the comments, paying little attention to the video. I only just paid attention to this second topic when he mentioned bacteria causing tape to curl.
Wait, how did we go from a vegetative state to getting power from evaporation?
That evaporation engine sounds like a bigger version of the scheme at the end of the 19th century to cover all of Niagra Falls with a power station and use the power of the falling water to generate electricity
Odin029 , currently, there are at least three hydroelectric powerplants at Niagara.
There was a plan to completely cover Niagara with a powerplant. They use a portion of the water to create electricity, but if some industrialists had their way it would have been impossible to see the falls from the outside.
Hi scishow I am your fan from a long time from now. Can you please make a video of nuclear reactions. I can't get it how nuclear scattering releases energy, but nuclear synthesis does as well. Keep on the good work!!!!
By nuclear synthesis, do you mean fusion? Then:
Some atoms are bound together easier than others. Iron is the most stable element, and all elements with atomic number greater or less than Iron have more energy in their state. So, when Hydrogen fuses, it releases some of that extra energy, and when Uranium splits, it also releases some of that energy, both tending toward iron. You could split Helium or fuse Uranium, but both would require energy put in.
I've actually had this idea in my head for a while. Think of a dam, or a water mill. What is it powered by?
Well, water, which usually is kept running through evaporation. Evaporation is the result of solar energy, gravity, and certain atmospheric conditions. An evaporation generator is basically like solar power, except gravity shoving it a long a little bit.
Evap engine on top of Desalinzation plants?
My dad is in the ICU right now he had a stroke he wake up sometimes but he's unresposive.
How come I can create clones from my succulents and cacti cuttings but not flowers or other plants?
Now we just need to figure out how to fix the Lake Meade shrinkage problem.
Wouldn't covering the entire lake.. stop evaporation though? Or at least significantly reduce evaporation from solely sunlight?
You see, the engine would have solar panels on top, to power its heaters, to heat the water :P
But really the evaporation engine sounds ridiculous to me. Not only do people not want a scenic lake to be covered by an enormous machine, they don't want to see those machines covering any body of water period.
Just stick more solar panels in the desert.
Solar panels in the desert will not power the whole US. Electricity cannot be losslessly transmitted over great distances, so places like the east coast in particular will always need something more.
My buddy told him if he ever fell into a coma, give home a bump and then a line. If he still doesn’t get up, he’s done for
My neurologist that I see for my Epilepsy never told me that the Vagus nerve did so much because I am getting VNS surgery and knowing what this nerve does now if they do something wrong during the surgery I can be screwed.
So it can be used to wake up on time for school?
Oh I was hoping this would teach me how to stop dissociating
What does "evaporation engine" have to do with "vegetative state"?
If you take the energy out of evaporation don't you get less rain to grow the plants and trees we need for are food and oxygen?
We need filters for CO2: Carbon13 which uses electrolysis to separate it into O2 and carbon deposits. we can then use the carbon13 soot for something.
I wonder just how much energy it would take to amass the resources to build the infrastructure to reap the power from evaporation and just how much energy it would take to keep that machine in working order.
How about a show that answers these questions for the wind turbines.
Fix that motor cortex and I'll be very interested.
I read about this on the news
I'll share with my friends... They will benefit greatly from this new discovery !
This is more interesting than the pickle Rick is possible theory.
I remember reading about this on ifl science
I love it when Lego is used to make practical things.
I love you hank green
"Just weight a little and lil bacterial spores are gonna power ur home when they get a lil moist..."
Best. Sentence. Ever.
DID SOMEONE SAY.... VEGETALS?
birthd wt tickle me

Mighty fine safari shirt.
Evaporation engine? I am extremely sceptical about that. I'd like to see Thunderf00t take a look at this, see if the math holds up.
4:29 getting watts per year? I don't think thats how that unit works.
Just saw a House episode, Son of Coma Guy S03.
He said "moist".
"getting a little moist" even better
mikeleeisback _moist_
So does "unresponsive wakefulness" mean the person is not aware of anything that is happening, or just not able to respond?
technically awake yet unconscious
What if we dig out a reservoir in and ideal location for evaporation below sea level, and siphon water from the ocean into it (with a giant siphon.) That way we have a source of water, we aren't harming an existing ecosystem, and it could double as a source of salt and other minerals.
Please make a scishow psych video with the same title!
I love you hanks
ok there are some weird audio sounds/fragments in the background that are really annoying, don't know if it's only my youtube player or if it's in the video but i thought i share it
couldn't we take advantage of the rising ocean levels to produce loads of energy and protect seaside areas in the meditteranean by building a big dam on the strait of gibraltar? and maybe in the daranelles too?
Is that supposed to be just megawatts? Not megawatts per year.
Wouldn't the evaporation engines also be subject to weather conditions, like wouldn't it generate more power when it's sunny outside? I guess the effect would be diminished because the water stores the sun's energy in heat even when it's cooler and the sun's not out.
Keep in mind that watts are a time-related unit. One gigawatt is the same thing as one gigajoule *per second.*
Why not use Orbeez ?
They also expand when moist.
Since evaporation is a solar process the evaporation engine is unlikely to be as efficient as straight solar collection methods. You also have the headache of trying to maintain the health of the bacterial colonies. What do you do when the bacteria mutate and evolve as a species into one that is less efficient at this process since there is no environmental survival pressure for them to perform this trick with evaporation for our benefit. What will be the maintenance cost of this evaporation engine when they by necessity have such a large surface area, larger even than a solar panel of the same power level. How do you deal with tornado damage, hail, birds nesting, vegetation growing on your collectors, soot, ash, and windblown dirt accumulating on the surface. These things all affect the health of the bacteria you are relying on to generate the energy. Washing it off also washes away your bacteria so what can you do?
A better idea would be to create artificial lakes in deserted areas and using them for the evaporation engine.
Oh wow! It looks like you guys figured out how to do green screen! Great!
Sorry, what? Are you new here, or did you not notice most SciShow episode have used green screen for 5 years, or are you making some other point?
Emajekral idk. Maybe he thinks it looked worse before
Maybe it's a bad vegetative state joke. You know, greens?
Emajekral Haha no I've been subscribed for years and there have been so many episodes where you could see the green screen any time the host would move their hands rapidly, or through their hair.
+Emajekral He's talking about how you used to be able to see a green edge around hosts because the chroma keying was done badly. Hank has no green edge around him now.
Dang we can power the flux capacitor with evaporation!
