- From Lawrence Berkeley National Labs to Silicon Valley, researchers are manipulating particles at the atomic level, ushering in potential cures for cancer, clothes that don't stain, and solar panels as thick as a sheet of paper.
KQED's Quest explores the future of Nanotechnology.
This really makes me want to have a career in this field. Time to change my major!

I'm not sure if I should actually respond because I don't think you'll understand regardless. They are talking about the energy of the electron, and how quantum confinement can elevate that energy. The energy of a nuclear bomb comes from the binding energy of the nucleus. That energy is not increased here.
this teck kills evolution reasoning. to complex for random chance to happen. too meany moving parts.
Hi Everyone:
I've just removed a large number of nasty comments (and their users) that focused solely on religious differences. Please keep the discussion here on topic. Trolls will be blocked.
Thanks in advance for your help -

Hi Everyone:
Reminder from the editor: discussions about promoting / bashing Christianity or other religious views are considered off-topic, and will be removed.
Commenters who make personal attacks or offensive posts will be blocked.
Thanks in advance for keeping the conversation civilized and on-topic.
Here is a way that a residential house could effectively store solar energy during the five hours of good sunshine, to last for the full twenty-four hours in a day. Use a hydraulic elevator system lifting a very heavy weight, where the energy is stored by the gravity of the weight. When the sun goes down,or when more power is needed during the five hours of good sunshine, the very heavy weight movement is reversed and the hydraulics is used to generate power. Maybe more days could be stored.
Berkeley ! WOO WOO!
I think you missed my point. Sony bought several laboratories to develop chips for the PS3, and they're obviously going to wait a few years until they release the PS4 since the PS3 has hardly even started selling yet.
Sorry, but I am a Mechanical Engineer at Cal Poly, I have a 4.0, and I really don't care about other peoples attacks on my religion. I have my beliefs, you have yours. When people attack eachother's beliefs, it simply means they are insecure about their own.
We have already isolated the triggers for aging. Although nobody has yet replaced them. It's not that we can't do it, it's just that some people find it unethical.
nanotechnology will be an evolutionary step in tech.
I was just accepted to UC Berkeley's undergraduate engineering program. If I decide to go there, I would very much like to do research in nanotechnology.
2020 anyone?
1984 was written in 1948, he reversed the years. he worked for a period of time in the government, which may have been the reason he was particularly "on the money."
its annoying to think that were so close to having technolagy that would enable the whole world to live with what they needed, yet due to the systems we live in it will be packaged and sold to us for a high price, leaving many without.
anyone who's interested in this area would also enjoy a film called ' zeitgeist addendum'
Damnit, I accidentally rated one :(
Thanks for this video! This is way above my level of intelligence, but nanotechnology fascinates me! Thanks again!
this tuff is amazing.... shows just how much more is possible that we have no idea about today...
Thanks everyone!
I think Star Trek was based on the writers informed vision of the future, the space ships not really that interesting but the on-land parts look really cool.
Real technology is the medatitve study of how your consciousness effects reality, that's the future.
can you like take the little molecule that creates light because it hits the "walls of the box" and put ALOT of them in a room and turn on the machine that transforms the energy of light into electric energy and you got perpetual energy :P
the key to reversing cryonics suspensions in the future....:)
If you want to know more about the potential of nanotechnology I suggest reading "The Singularity is near: When humans transcend biology" by Ray Kurzweil, it will blow your mind away.
But going back to the molecule in the box.
These molecules look colored because of the visable light radiation to which the electrons absorb.
If the source of visable light radiation is taken away then these molecules will not look colored.
basically atoms need a source of energy to excite electon from a low vibrational electron energy level to a higher electron level.
For example.A substance looks blue because it has absorbed mainly the orange wavelength in the visable light spectrum.
perhaps the comments have gotten slightly off topic? not that people on the internet ever stay on topic for more then 30 seconds anyway....
any way, nice video not really any new information but a good way to present it
Yes, we are working very hard. You're welcome. :)
any body guessed why all the images we see are black and not in color well it is because light waves dont come in the measurements of atoms the only electromagnetic wave that comes in that form is gamma radiation but you dont want a lot of that in a room they use electron microscopes to shoot electrons as they reflect they see the image electron size wide, long, high which is very small.
this video fails to explain what nanotechnolgy is. So what is it and how has the research come. Is nano technology control of a compund or element, how do they actually get something as small as a nano, and how can they computers in nano form?
Make nanobots that constantly repair and up keep human insides for eternal life. I would love to live forever!!!! I don't care if I out live my friends and family....ill just make nu ones.
Science is the holy sprit when love is in the equation.
seriously. we should stop doing science
Good vid. Thanks for uploading.
@Tommyfmx Money is just the trade/labor reciept for stored energy...another words its a just a usefull accounting mechanism...the real value underneath it all is the stuff we make and the services we render...things and services are whats desired by all biological organisms...weither they have paper reciepts or not. Desire for things isnt bad..in fact it motivates...and is why the squirrle works hard to store his nuts. Greed is exclusively seperate and instead desire unchecked by morality
I am a christian, and let me tell you that you people are hilarious. You have such a strong belief in NO BELIEFS! How does this even make sense? You make descisions based on "right and wrong". So you must believe in a set of moral guidelines, which is basically a religion. So when you make fun of other peoples beliefs, just remember that your beliefs are only followed by you, and our beliefs are followed by millions. Who do you think is right, you or the rest of the world?
exactly you are a genious you have vision yep be as we call GOD and know everything by simply have a computer at the size of an atom inside your eyes and with that i can answer anyquestion you make to me since the hardrives of teh future will be so big that you can put all the info in the world inside that and know any history any language anything i really want to live to see all that i can see it already no need to work or learn
finally i found an inteligent person is ovoius were we are going is ovoius sorry for my terrible spelling i speak spanish but our race can think so we create something that can help us thing faster i got a surprise for you but yes we wont work we learn today but someday not too far we have no need to learn anymore
Larva Aetheriust : stupid remark, as God is a meme, an idea, a way of life . God did not exist, period.
You can help others without believing in a dream ghost. You can be good without expecting to go to a pink sky with a loving father made of clouds.
Awake, please.
maybe but what amazes me the moust is when we can play to be god literaly and dominate adn and all taht we will perfeccion our race the way of looks everything outside inside nanoc cirgury no marcks no cuts is like been od some how in short EVERYTHING will be possible
wow watching how bodies does have just a bunch of different motors, we really could have been created, like a perfect clock that doesnt need to be wined for a long time, any by wined i mean death.
think about that for a second, youll see what im saying.
I think it will have a huge impact on the human race, technology beyond our dreams, but we'll definitly have to watch out for the risks and ethical problems! It will change things in EVERY field of science.
Wow I like that last bit. It's really unethical to not act yet at the same time it should be the public's obligation to at least now a little aout nano tech, so thy can be an active part of the debate. Wow that speaks volumes.
money isnt evil...greed is! Or the human application of profits for evil. However profit appeals to the cost benefit trade mechanisms that drive all biological organisms and evolution itself.
Nanotech is potentionally a powerful technology, but as is the case with any tool it is a double edge knife, you can make a meal with it and you can also use it as a weapon ti kill somebody
@ThirdRomeAquilo It could also help Africa, you know? Say for example they manege to create very efficient and very inexpansive solar panels with the technology. It would compete with biomass as an energy source which in turn would lower food price and this is great for any country with starvation. And of course it's perfectly possible that they would eventually develop and benefit more directly from our tech.
A big part of why people learn to be "bad" is in the current system where they've come to expect their lot in life (and that of their children) to be one of poverty. Do you doubt that nanotechnology can change that? When people can make what ever drugs they want right inside their bodies to you think there will be any drug related crime?
What happens when a youth in Uganda can manufacture oscilloscopes or computers or hamburgers or vaccines at home?
@hede88 Such a world would be one without scarcity;a logical paradox. This must include the removal of time as scarce in the human life. people economize choices according to time and preference, exchange with others, and the most marketable goods emerge as mediums(money-taken over by gov unfortunately). It is all the function of the pursuit of one's preferences. While he may not have meant it, such a comment necessarily implies knowledge of others preference ordering-a psychological phenomena.
@sibko Applying this technology to social phenomena--e.g. economic systems--is about the biggest mistake humanity could make. Heizenberg already discredited the concept of determinism decades ago. Why should this apply any less to people's actions? What scientific technology could reveal individual preferences? What an arrogant notion this is; achieving it would mean man has accomplished God-like omniscience.
@sibko with all respect, I'd have to disagree. You seem to have the idea that by creating a non monetary system we can enhance the lives of people. The only way that a non monetary system that doesn't look for profits is put in place is via the government.
If the government is needed to subsidize nano technology in order for nano technology to be successful then nanotechnology is no more efficient than any other means of cleaning water or creating clean energy.
your statement creates quite a conundrum. If our theories have *already* been "proven wrong" as you say then why would we have to cut down other theories for fear of being proven wrong?
we cut down theories because science is like evolution itself the strongest theories with the most evidence that can overcome intelligent criticism survive.
great theories thrive under scrutiny just as an athlete thrives on game day the trial makes you stronger and only the weak cry when put to the test
You mean the experiment where they apparently wanted to cloak a battleship? Hell, even the existence of such an experiment is highly disputed. And what does it have to do with people reading thoughts and materializing things with their mind? If they really could do that, the whole world would have been theirs a few million times over now. Imagine creating something with your thoughts alone; only your imagination is the limit. That's Godhood in its own right. Do you even read what you write?
Yes Mwermaidinheaven.
you are absolutely right.
the commmentator always sexes up the story for the listeners to become `fixated`.
Just because it is nano technology it doesn`t mean that the laws of physics in relation to the way the atom behaves are completely new.
Sure we will find some amazing new uses for this technology but I`m afraid that if want to find a new law of physics then we have to dig a lot deeper than just making things a lot smaller.
they sad that when they take a little piece of the element it glows a color
and the energy it uses to create the light is as I understood the energy from the molecule bouncing in the walls.
and you know solar energy can be turned into electric energy so why wouldn't the light from the molecule be turned into el. energy?
I see you confused so watch the part of the video from 3:15 to 3:30
That's quite a spiteful response. It's interesting that someone visiting a webpage about science would assume absolute knowledge ("there is no God") in a retort to someone they consider deluded ... The fact is that science is limited, and it is far more logical to state something could exist than does not exist.
You seem very set in your thinking, though, so I don't think any further reply would do either of us much good. God bless.
Well I'm no scientist but I can see two possibilities for this kind of technology
1-We get to use it right and the world becomes heaven itself, with no hunger, disease, need to work or study, where energy comes from natural sources and there won't be any more pollution, where we could be able not just to fix our ozone layer but create one for other planets and live there, where we all get to live well and explore science even more and achieve some kind of god-status lifestyle
Not quite Bauggio-
Imagine if one kid from a college university had access to a nano machine and could produce a single layer of a substance. That he could then go to another machine and copy-past like crazy and build his own nano-design & print machine from parts. He could then produce as many of these as he wanted and give them to whomever he wished. And if he charged, someone else can do the same.
I expect nano tech to help clean the environment, create kick ass gadgets and scare others...
Ill prove god dosent exist. When god created things he saw that they were good. As aposed to bad. Had god saw something was bad, It would have meant that his creation was flawed. Meaning he is capeable of failing. So since god could fail that means he isnt in control of nor does he know everything there is to know. Meaning god is not omnipotant, thus proving he if he was anything he definatly wasn't a god. So god negates his own existence in his own words. GET OVER IT.
@alexandradeyl well you see I'd have to do something as incredible as Tesla and formulate something entirely new in a year, It took10 years to master velcro,in a year I would have to come up with space age tech alone. I like sleep man, I dont need that kind of stress.
I'll do it when my degree is done and im bored
i was thinking of doing something nano for my thesis, but my lecturer advises against it because its still so very new, and information is difficult to find, and he has a point there, and i'd need years to figure out something epic. but im still very into it, Its my main goal, nanorobotics.
yay science and Engineering
Wish I could be as optimistic. History is full of tech advances that have been redirected for commercial or military use, co-opted and made economically exclusive, suppressed or even destroyed, regardless of their potential benefits for the common good. The power of greed trumps altruism - sad but historically true.
anyway, I'd like that somebody would tell me a video which talks about actual results in
nanotechnology like: Self-powered smart windows, trap captures cancer cells in blood...
I found articles but they're hard to understand due to I'm not english-speaking.
thanks!
I have researched what I know, backed up by people who have spend their life researching these matters. Blind faith does not please God. He said My people are destroyed for lack of knowledge. Wisdom is the principal thing, so therefor get wisdom, and in all your getting get understanding.
We can do that now without nanotechnology. It's called electrolysis.
However, removing the hydrogen from water produces only oxygen. Air is a combination of nitrogen, oxygen, carbon dioxide, and some minor constituents.
The point is that you don't need nanotechnology to split water.
A Christian accusing someone(falsely, may I add) of believing in fairytales is ironic. "Origin of Life", which just happened to have been written by none other than Darwin, disproved it. It just happened that Darwin managed to disprove not one, but two fairytales.
You're wrong yet again, but nice try.
lol am i the only one that thought of the risks this might bring? sure its breaking news and interesting what the future has in store for us.. but if you have biological weapons now.. think what they might be able to do with nano technology?
man.. this discovery is like the greatest gift and curse.
I like how that scientist keeps wanting to talk about God, but instead says nonsense like, "It's fascinating, the mechanisms than Nature builds," as if Nature is a sentient being ...
Man, this video kind of makes me want to change from Medical Physics to Nanotechnology ...
This technology should be used for the pleasure and benefit of those who made it. The people who spent a large portion of their lives dedicated to making a better tomorrow for the ignorant, whiney, peanut gallery, children, deserve to have opulent present.
The natural man can not understand the things of God, they are foolishness unto them, neither can he know them because they are spiritually discerned.
You are left brain mind controlled leaving you right brain spirtual/ wisdom side under developed.
? Big Bang Theory, Singularities, Expanding Universe....all these theories derived from people like einstein n hawking all point to a creator. Hence why they all believed in some type of god.....so designed, ya science points to it
You could only look back into time, not travelling. And looking back into time will be a result of time space bending and will not have anything to do with traveling nearly the speed of light or faster (which is impossible).
But then who would the wealthy exploit? This could ruin their fun. Expect this technology, like all others to be employed to promote the status quo, or more fully entrench the entrenched and further enrich the rich.
Job shortages in some areas and not enough houseing and then they would build more and it looks crappy when all u can see is apartments and condos everywhere and ur all packed in i like the country so but you do have a point
Whatever they super-human abilities they gonna promise you to gai", please don't take the Verichip when the time comes. It got strong similarities with the "Mark of the best" in the bible..
The polymer-based solar cells are great. They are not as efficient (currently) as monocrystalline silicon, but they are cost effective. I used a few to power a model of a hydrogen powered car.
@utoostrict
Academic research creates the knowledge and modelling systems to allow for real engineering to take place.
Academic research allows source materials so that education can advance.
who wants to go to college for nanotechnology create our own nanos that make our muscles super human and repair ourselves faster and live forever! im serious im going to be like fucking wesker
well I was stoned all the way from Thursday to Sunday.... but if you just focus enough on my comment you might see the light... well you might realise what I have meant with perpetual energy
description-
"and solar panels as thick as a sheet of paper."
it's "as thin as a sheet of paper", not thick, you are trying to describe how small it is compared to the original or prior version or form.
This technology should be used for the benefit of all human beings.
Not for PROFITS or ETHICS and SUPERSTITIOUS values.
This is the next step to a non-monetary system, let's not fuck up.
what if they make a robot not to kill you but to kill the robots inside you that are designed to kill the robots that are going to kill you and then send in the robots to kill you.
lolz but time machines will never be possible space stations on mars will lol only way for time machine is staying in space for a long time ex:5yrs in space =50yrs on earth einstien.
You have it all wrong. Instead of explaining Darwin's theory to you, I'll just have you think about this.
If "Something Else" created us, then why do we have tailbones and appendixes?
Well at least now even the smallest motor we've created is still pretty massive compared to, say, a human platelet. I'm sure by the time nanotechnology becomes a weapon I'll be long gone.
The Lord is my Healer!
would anyone be able to tell me which television programme this is from, im using it as a source in and essay and need to know the origin of the vid.
thanks in advance
Indeed. One day it will kill today's semiconductor technology. Thinnest deposition I worked with was about 40nm but it was only one layer...
Yes,nanotechnology is amazing.
our heart would be the pendulum. or what ever, the thing that swings back and forth in the clock. you see what im sayin
@presbarkeep I like the way you laugh with people to loose your frustration because you don't understand a shit of what they say ... don't worry, me neither :D
So to which molecules do you talk of ?
And where do such molecules obtain there energy from in order to create light ?
What is the machine that you speak of ?
MeckelBot study chemical engineering, course: chemistry and material engineering; then take Engineer's degree in nanotechnology. after that your in the game.
As a man of quantum confinement I challenge
you, man of reason, to see who can knock
themselves out first by bouncing our heads
off these padded walls. You first.
please leave tinkerbell, santa, god and the tooth-fairy out of any classroom, science book, or any serious discussion. fairy tales belong in children's books.
that could be you if you spend your time helping with the advancement of science and technology. But I forgot, XboX will save the world from itself, right?
Ya, I read Prey. But there is a lot better one called "NANO" by John Robert Marlow. Its a fucking trip ! Its the best answer yet to the Fermi Paradox.
if you'd like to see a mind blowing example of a near utopian nanotech future read The Golden Age, (but don't bother with the next two in the series.)
What's curious is how so many of these nano-experts have their left shoulders depressed..
If a human were to live 300 years we would overpopulate the world even more than we already do. And more people means less food per person.
I love this shit! I consider myself so fortunate to be alive during these times. I hope that we make a quantum leap in this field.
damn, this stuff is like something straight out of Star Trek or the Terminator. It's kinda scary even.
@Face2nutts Like what? I rather know the unknown then not know it all. At least I will be prepared if something bad happens!
its already been dubbed as the cure for cancer :P a good thing,, bad side, the doomsday scenario called Gray Goo, look it up.
For everything great man achieves, religion has to come along and stomp on it and bring us back down to a primitive level.
