Been saying these same things for at least 15 years as well as taking a systems approach to our architecture, heat, water, cooling...basic needs. Flexible solar has been around since Jimmy Carter who didn't support it back then. It seems we always have to be in crisis mode before things can change. Glad to see this presentation, but wish there were more details on production costs and output efficiency...so people could get it. Thank you Hannah, your passion is shared by an old engineer.
It's not a crisis perse we have to be in. There also needs to be a good cost-efficency ratio, as well as a market/customers. And even a crisis wont make it magically possible to just change something. There are still poloticians who take bog steps in restricting green energy as much as possible for other big corps and/or because they are (please input your personal favourite word to describe people you hate). Germany for example has laws in palce how far away you can palce windmills from towns/cities and from one another, to not disturbe tha natural view. Which in comparrison how close you can place coal mines to towns (much closer) and destroy nature, is just a freaking joke. And this even while earth is (currently literaly) burning and there a re more catastrophes every year
The cost of solar energy is dropping to the point where it's cheaper than coal and nuclear already. Those are not the only questions that matter, however.
Durian - no. not necessarily. If you're on the Titanic, and you have a choice of using the lifeboats you have or waiting to build a better lifeboat, you're going use the less developed lifeboat. At some point you run out of time and options, and have to use the less than ideal solution.
The widespread rollout has little to do with efficiency, and everything to do with politics. The US is really one of the few advanced economies failing to roll out solar. China, the EU are all driving hard toward solar.
It lacks a lot of informations. She could have condensed it into one paragraph. It would be awesome to have details on how it works, about the amount of energy it can bring to buildings, about the maintenance, the environnemental and economic aspects, the way the cells are produced... Anyway.
Lalks ' yes, this would be interesting to us, but probably irrelevant and boring to the general public. I think the talk was excellent for conveying the new idea to gain public support. And to inspire people who are interested in this work to do extra research. ☺️
Look up 'Organic Solar Cell'. The solid state physics gets complicated... but be patient and sit through it; it is really neat -- but it can't supply power for a country at 100% without a huge number of high energy density battery arrays.
It's interesting. I have a few questions : how efficient is the conversion of light to electricity ? How polluting is the creation of that ink ? How do these panel age ? Once we dispose of those OPV, are they polluting ? Currently, silicon PV are relatively energy consuming to produce, relatively low efficiency, not so great of an aging material, and not recyclable and polluting once disposed of. Still better than charcoal.
Ben Saber oh, there's a good chance that's the case, but when I hear of a brand new technology supposed to save the world, I tend to be extra cautious, just because of things like "solar roadways" and other way people have found to exploit the need for environmentalism to con people out of their money. It's always good to ask about the downsides, the cost-benefits and the long term viability before jumping into something new. On what has been presented here, it seems a plausible thing that could exist and be beneficial, but this is TED, where companies go to make their promotion, not a science paper with details. they come to tell you how wonderful they are, not what are also their flaws, how far off they are from commercialisation, etc. Understand me well. I'm not saying it is bullshit, as I heard about them literally an hour ago. I am just cautioning that bullshit exist, and offer some axes of reflection regarding that. But it could be the next best thing since sliced bread, for all I know, and it sound promising.
Roger Toledo the "organic" she uses is the same one of "organic chemistry", the field of study of things based on carbon, including the fuel that power cars and polute through gigantic oil spills in the see. Beware of "organic" things. The term is almost as tricky as "natural". Uranium is natural, too. Same caution.
Even if the current produced is less it is still a more efficient power source. Through ease of production and weight alone will make these cells more efficient and cost-effective. I would really like to learn more. Yes, the presentation was superb.
What is the efficiency of the ink? How much power does a square metre produce in direct sunlight? Given the thin layer, how much energy is absorbed at uneven angles? Can I coat the arms of a windmill with this to produce a hybrid unit? I feel the clumsy shoe analogy could have been replaced with some answers to these important questions.
The efficiency of (pure) organic solar cells is around 8% - 10% when it comes to comerce. Roughtly you get from one 1m² something around 50 - 60 Watt/h. Important here is, organic solar cells work better with less light then perovscites or Silicon based ones. Also, organic solar cells can be (technically) placed nearly everywhere on nearly every shape you want. So the area you can use to generate current is vastly bigger. Further whats in development are clear solar cells who could be used as windows. You can place organic solar cells on the tower of a windmill (Which has also been tested already). Wings I am unsure, cause you would need to think how to run the circuit over the moving parts
The speaker failed to touch on the two main ingredients for a successful wide adoption of this technology; cost and efficiency. Lots of people are not willing to do massive investments that take a seriously long time to justify itself. And even more people are unable to do so. Solar panels still have a fairly low efficiency and require large and expensive installations to cover the power need of a normal home.
There is also the fact/problem that areas surrounding Solar Farms have increased heat levels. Sometimes even to a scary amount. What would this effect have on a large scale Building that has 70% of its windows paneled. it may be shaded inside but what about the land around the building.
Hi. I do a bit of research in this field and wanted to answer your questions. Firstly cost: Organic solar cells currently cost almost the same as silicon solar cells. But that mostly due to lower demand. If production were to increase on the same levels as the current silicon solar cell industry, they would be much cheaper. Secondly efficiency: Organic solar cells have the drawback of not being as efficient as their silicon counterparts. You could say it's a trade-off from being more flexible, thinner, lighter and easier to manufacture. The other drawback is that they have a shorter lifespan than silicon solar cells. Additionally: The time it would take to get back the investment on organic solar cells have been estimated to be much lower (a couple of months) than silicon ones assuming the production scales up.
It's fascinating stuff and all, like many other TED talks inspirational, but I think solar cell companies have to shift the tone from an environmental standpoint - which is of course important but people are kinda tired of hearing -, to a more economical one. Because that's the thing building owners and construction companies will be convinced by and will invest on. It's a sad reality, but it is what it is. And I think the entire solar cell industry is mature enough and has been around for long enough to just put it out there. Put simply: how much investment we're talking about for a standard size building, how much more production has to scale to bring prices of those processes down, what sort of savings will those buildings have on a daily basis, what's the ROI, how much extra in construction costs we're talking about, what are the numbers for examples given, what's the maintenance cost, etc etc. And I know there are trappings in solar power production. It simply cannot generate as much power as more traditional technologies, but if it gets to a point where it makes sense to invest, then it should be enough for lots of people to adopt it. But it has to be presented in hard numbers. You need to get hard realistic studies of effects out there. Yes, solar is less poluting and all, but by how much? How poluting are the processes of creating said cells? How it's expected to scale with mass production? What are the advantages of having buildings producing solar power (like in an outtage, building will retain the ability to produce some power). What about batteries? And then stuff like, how much less CO2 is being put out by building a city full of buildings with solar panels? What jobs will it generate? What systems people are using to connect to the grid? Even if the answers are not totally great or favorable, people need to know. I think lots of people wouldn't mind a less efficient paradigm, and/or something that costs a bit more, given the benefits.
Smaragdwolf less prize? Rectangle solor panels that you see everywhere on roofs put out now about 300-375 watts per panel a string of 10-20 grid tie can power an American house .(and sometimes sell to the electric company) You need 100 - 200in organic cells, on a house and there is no space for that
Production of silicon and the production of silicon solar cells is expensive and needs lot of energy and partly hightoxic substances (my education was in that field). These OPV here are insanely cheap to produce in comparison! Even if the efficiency would be only 1/5 of silicon solar cells, it would still be a great cost/efficiency rate.
Julia, i don't want to be rude, but if you have no clue about the costs and the current efficiency of organic solar cells, then why are you making these nonsense claims?!
If the tech is older, and the only people who knew about it (eg, yourself, who saw the video) haven't put it into use, then obviously more people need to be told about it... and err... that's what this video is... it's telling more people so more people can find out about putting it to use Or, maybe the tech isn't the exact same tech, maybe there were issues that arose that needed to be worked out... you're not going to get a full history of development in a 10 min talk
maybe the new info is....that there already companies who producing this solar cells my Friend ;) Have to know.....in a few weeks i could start working for one.
Smaragdwolf I worked for a solar cell company for a year. Absolutely loved it, but our major investor pulled out for an oil company instead. Good luck!
I don't remember how many times I've heard the promise of printable or even paintable solar cells. I hope they become a reality but a business plan speaks louder than a nice tech demo.
What you are talking about was solved years ago. China just put a new solar plant into operation it can generate 40 megawatts of energy and power 15,000 homes, maybe 5000 US homes.
TOSStarTrek what next gen batteries? All of them i heard about are just prototypes that never reach commercial market. Would you mind tell me which ones you are talking about?
The two front-runners right now are solid state batteries and Graphene batteries but there at least ten different types or subtypes being worked on right only one needs to make to market.
TOSStarTrek well my point exactly, all of them are just in prototype mode and couldn't make it to the market for years. This tech is not new, it's years old, i heard about ss battery and graphene batteries at least 2 years ago. Don't tell me 2 years wasn't enough time to even make a first generation to be released on the market.
I'd like to see when they came up with their ink, because a few years ago someone else came up with the same ink and actually discovered it and it's been making supercapacitors out of it.
Dude from the future here. The edging is real, we still create reaource intensive solar panels as cutting edge technology which contributes heavily to pollution.
Now if you took that ink and you made the solar cell and then you made a supercapacitor out of the same ink using thin aluminum and the ink itself, you could probably produce a panel that's flexible and does not need a battery and can run at a low milliamp for quite some time.
What's the efficiency? Presumably it's less than 20% which silicon cells provide, though these may look prettier. Very efficient solar cells use multiple layers to harvest different wavelengths. The cost per watt could make these cells useful.
I only copy/paste the following from a company: "We already hold the world record of 13,22% cell efficiency for opaque (non-transparent) organic solar cells. In production, we currently achieve 7-8 %. The latest development allows transparency levels up to 30% with an efficiency of 6%. The intrinsic lifespan of our small molecules is >25 years (extrapolated)."
So what's the product/technology called? Can't really go look for it if I don't know what vendors would be calling the stuff. I could see myself put sun to hot water things on the roof, and the foil things on the windows, but not without knowing what it's called.
Very interested in this topic. It will be more efficient to extract the energy directly from the sun but there is the problem of the rotation of the earth.
*Wow. For the first time in awhile, I find myself currently reading several physical books at once, and the main one is "Design Professional's Guide to Zero Net Energy Buildings" by Charles Eley, rather relevant to this talk.* *Also, I am kind of drunk. Typing is hard right now. (shrug)*
10 years ago I remember a guy spearheading solar ink and he bought an old newspaper printing press to produce flexible panels in high volumes. It looked so promising but dissapeared. He shoe analogy was terrible because we all know her little designer shoe is not comfortable and it costs a ton more with no practical use besides "it matches my dress"
I opened this video in a tab, began listening to it prior to opening the tab. I was compelled to open the tab to verify I was no listening to a text to voice video. There is a lot of issues with material degradation to any laminate material, delamination, environmental ingress and mechanical damages etc. Better to genetically engineer a bio accumulator; skin a tree with organic technology from the DNA level, build into the tree a storage cell akin to electric eels and fish, then harvest the accumulated energy. Plant your solar generators where-ever there is soil and water and be confident that it will always face towards the best sun and will perform continual maintenance and repair to itself.
Ubiquity of solar, fully distributed power, is the key goodness for society over time. Centralized power is never good, even when it's electricity or tyranny.
I wonder how efficient it is today compared to current tech. It's less that's a given but how much? Tech is great though, can do stunning and sustainable architecture.
How effective is this technology? How many percent of the suns energy can it use? Most current photovoltaics cannot make use of more than 20 percent I think - is this better? If solar becomes more widely used, we definitely need to increase percentage of the suns energy that can be used! The technology does sound pretty versatile overall and should indeed open up new uses
she says normal solar panels make aesthetics a challange, but i think the houses at 3:14 look much better with the panles, less boring, like a designe.
Organic Photovoltaics are a cool concept but are not a new technology and are not commercially feasible at this point. According to the DOE: "The low efficiencies of OPV cells are related to their small exciton diffusion lengths and low carrier mobilities. These two characteristics ultimately result in the use of thin active layers that affect overall device performance. Furthermore, the operational lifetime of OPV modules remains significantly lower than for inorganic devices." Silicon based solutions are still our best option, as the presenter admits at the end.
Hi, I am interested in this technology, and I want to setup 1000 sq metres of these solar ink panel so please give me some information regarding imports of these panels in large quantity..
sounds great...BUT now it is 2019 and in 2015 it was commercially put to use... why isnt it still not mass produced..... ooh let me guess.......indeed .... the commerce.... the big bucks greed comes first.....
She seemed quite robotic. Great idea though. At MIT I saw a presentation where they could make solar cells with a 3-d printer. Maybe this is the future. Imagine designing your own solar cells.
- The introduction lingers a bit, I know the enviroment is an issue, don't depress me now. - The Prius Effect suggests that aesthetics is a minor problem. People like evident bulky solar panels because it signals that they care for the enviroment. - You say cost effective? My family just cannot afford to install solar panels. I computed the return of investment and it is in the decades. In fact, an hybrid solar and wind power solution for the house is better, we just don't have the space for the wind turbine. Waiting for cheaper technology makes more economic sense at the moment. - Would this be cheaper? I don't know. Perhaps where you are. As I said, it makes sense to wait. At least my city uses geothermal energy, but a the country in general uses fossil fuels as main energy source. You can try selling me the idea that we can change the wolrd starting from our homes... but no, I do not have the resources to produce cheap solar panels in my house. And politics? Teach me to dismantle the corporations behind fossil fuels and corruption, and hopefully without creating a militia. That's a dislike from me. Fight me.
OPV's have been around for a while. the efficiency of OPV is very small (20%. another issue is photochemical decomposition. you put any polymer under the sun, and it will decompose over time, much faster than existing solar cells. it may have its place for aesthetic architecture or neat consumer goods, but it's a tough sell for actual power generation. if you want the building to be off grid, you need silicon.
I believe the majority of this and all ted talk audiences know enough about man’s devastating effect on our earth and it’s atmosphere in the last 100 yrs compared to anytime in earth’s natural history. We just need to apply the solutions NOW.
My lil brother sells solar for a living so naturally, I asked him about Elon Musk and solar cities beautiful cells. He told me they may look good but as far as bang for your buck they are terribly inefficient. For now they're just for people with more money than brains. Unless they are greatly improved they'll remain a toy for the rich. I couldn't help but notice her presentation failed to mention anything about their effieciency. Great Sales pitch
This amazing invention may be a nice improvement in environment, but the true solution is to change american consumist lifestyle, that spreads through he world.
Nobody and I mean nobody talks about the construction processes, including materials used to create that building, those materials in constructing solar cells in solar panels or the type of metal used to create a wind turbine, until we have that conversation all of this talk is meaningless and nothing will change.
Points at a leather shoe...REALLY sustainable ! XD Doesn't even tell you that most perovskites are using lead and that "inks" are actually deadly solvents... Whatever...
3:33 Skip introduction

Indeed!

How much does it cost and how efficient it is and how easy is it to produce? The only questions that matter.
I quote you. Totally
The cost of solar energy is dropping to the point where it's cheaper than coal and nuclear already.
Those are not the only questions that matter, however.
No. Not the only questions that matter. Not in this time. Unless you want to redefine cost.

yup
the main thing is "idea", no prototype or technical information, as usual

The reason It is Not used is it put out 10% (in watts) of what silcon based panels and cost just as much. But a good idea that needs work. FYI
Production of flexible solar cells with organic layers needs MUCH less effort than silicon panels. Less production cost -> less price
Smaragdwolf less prize? Rectangle solor panels that you see everywhere on roofs put out now about 300-375 watts per panel a string of 10-20 grid tie can power an American house .(and sometimes sell to the electric company) You need 100 - 200in organic cells, on a house and there is no space for that

Can we use it in mobile phones? Install a thin layer of OPV under the display so the battery could be charged when exposing display to the Sun?
I'm confused no less than 8 years ago I watched a video of this technology...... what's new other than the fact your still not doing it....
If the tech is older, and the only people who knew about it (eg, yourself, who saw the video) haven't put it into use, then obviously more people need to be told about it... and err... that's what this video is... it's telling more people so more people can find out about putting it to use
Or, maybe the tech isn't the exact same tech, maybe there were issues that arose that needed to be worked out... you're not going to get a full history of development in a 10 min talk
It's funny, if everybody argued this way, noone would ever start using it.
maybe the new info is....that there already companies who producing this solar cells my Friend ;) Have to know.....in a few weeks i could start working for one.
Smaragdwolf I worked for a solar cell company for a year. Absolutely loved it, but our major investor pulled out for an oil company instead. Good luck!
ouch that´s hard....thank you and good luck for you too :o
Very interesting. Looking forward to see people incorporate this technology in their designs for buildings and various items.
Long overdue. Great and inspirational work by the solar energy researchers.
That is amazing! Solar can be everywhere without people even knowing! She's so pretty and smart I think I'm in love haha
She seems like AI a robot... So not human. Scarry...
tzunammi shadai
Lol you might be right
I don't remember how many times I've heard the promise of printable or even paintable solar cells. I hope they become a reality but a business plan speaks louder than a nice tech demo.
small info: some companies already selling solar cells made out of PET-foil and organic layers ;)
If the next-gen batteries do what they are saying they will be a major game changer and they talking a huge leap over the current batteries.
What you are talking about was solved years ago. China just put a new solar plant into operation it can generate 40 megawatts of energy and power 15,000 homes, maybe 5000 US homes.
TOSStarTrek what next gen batteries? All of them i heard about are just prototypes that never reach commercial market.
Would you mind tell me which ones you are talking about?
Pirate Me Lord i don't think "next-gen batteries " = double A battery ( the decades old battery)
The two front-runners right now are solid state batteries and Graphene batteries but there at least ten different types or subtypes being worked on right only one needs to make to market.
TOSStarTrek well my point exactly, all of them are just in prototype mode and couldn't make it to the market for years.
This tech is not new, it's years old, i heard about ss battery and graphene batteries at least 2 years ago. Don't tell me 2 years wasn't enough time to even make a first generation to be released on the market.
I'd like to see when they came up with their ink, because a few years ago someone else came up with the same ink and actually discovered it and it's been making supercapacitors out of it.
relax it's at least 5-year circulating scam
I have been waiting for this video! :)
You know what is even better? Solar Paint 🎨 images painting your house and never have to pay an electricity bill again
Dude from the future here. The edging is real, we still create reaource intensive solar panels as cutting edge technology which contributes heavily to pollution.
When is it available ? Price ? Any facts ?
Now if you took that ink and you made the solar cell and then you made a supercapacitor out of the same ink using thin aluminum and the ink itself, you could probably produce a panel that's flexible and does not need a battery and can run at a low milliamp for quite some time.
Does any one else hear Siri when Hannah speaks?
What's the efficiency? Presumably it's less than 20% which silicon cells provide, though these may look prettier. Very efficient solar cells use multiple layers to harvest different wavelengths. The cost per watt could make these cells useful.
I only copy/paste the following from a company:

It feels like this is just an advertisement of the solar panel without any description.
So what's the product/technology called? Can't really go look for it if I don't know what vendors would be calling the stuff. I could see myself put sun to hot water things on the roof, and the foil things on the windows, but not without knowing what it's called.
I'm thinking you could print this on some massive plastic sheet, and you could just roll it out on the ground, and back up into a compact shape
Printable cells and printable magnets could do great things together.
For "organic photovoltaic" , see "next way to have the knobheads over with something that cost 20x more than it needs to be ."
Very interested in this topic. It will be more efficient to extract the energy directly from the sun but there is the problem of the rotation of the earth.
Amazing... Thanks Ted Talks
It's a good idea for architectural design for sure. Though 8 years... means the cost of it is pretty damn expensive. Nice one!
Where can we see a demo of this technology, in action?
*Wow. For the first time in awhile, I find myself currently reading several physical books at once, and the main one is "Design Professional's Guide to Zero Net Energy Buildings" by Charles Eley, rather relevant to this talk.*
*Also, I am kind of drunk. Typing is hard right now. (shrug)*
Insane work, thats a right step into the future.
10 years ago I remember a guy spearheading solar ink and he bought an old newspaper printing press to produce flexible panels in high volumes. It looked so promising but dissapeared. He shoe analogy was terrible because we all know her little designer shoe is not comfortable and it costs a ton more with no practical use besides "it matches my dress"
Buenas como están disculpe, los vídeos en ingles será que pueden estar subtitulador por favor gracias
Imagine getting a tattoo with that ink.
BOI
and then use it to charge lightshows on your skin like onee of those deepsea animals!
Hammock assuming it isn’t poisonous
at worst case you could augment yourself with a small surgery like prostetics in a small tattoo type fashion
what a bright idea. you'd be the shining star at every party.
Is there a direct link to their research?
I opened this video in a tab, began listening to it prior to opening the
tab. I was compelled to open the tab to verify I was no listening to a
text to voice video. There is a lot of issues with material degradation to any laminate material, delamination, environmental ingress and mechanical damages etc. Better to genetically engineer a bio accumulator; skin a tree with organic technology from the DNA level, build into the tree a storage cell akin to electric eels and fish, then harvest the accumulated energy. Plant your solar generators where-ever there is soil and water and be confident that it will always face towards the best sun and will perform continual maintenance and repair to itself.
Ubiquity of solar, fully distributed power, is the key goodness for society over time. Centralized power is never good, even when it's electricity or tyranny.
The equasion is, how much energy do you need (X) to produce energy (Y). Right now X is aways bigger thant Y.
If we made it at home where we have to join the positive and negative terminal .Plss tell
I wonder how efficient it is today compared to current tech.
It's less that's a given but how much?
Tech is great though, can do stunning and sustainable architecture.
I want to use it for my self.. If the product is already in the market
How effective is this technology? How many percent of the suns energy can it use? Most current photovoltaics cannot make use of more than 20 percent I think - is this better? If solar becomes more widely used, we definitely need to increase percentage of the suns energy that can be used! The technology does sound pretty versatile overall and should indeed open up new uses
Very nice presentation
It’s nice to meet the lady that does the Sally computer type to Voice.
she says normal solar panels make aesthetics a challange, but i think the houses at 3:14 look much better with the panles, less boring, like a designe.
Does it scale?
Leather is a sustainable resource. Boots have there place to protect the foot. Therefore your opening point is mute.
Organic Photovoltaics are a cool concept but are not a new technology and are not commercially feasible at this point.
According to the DOE: "The low efficiencies of OPV cells are related to their small exciton diffusion lengths and low carrier mobilities. These two characteristics ultimately result in the use of thin active layers that affect overall device performance. Furthermore, the operational lifetime of OPV modules remains significantly lower than for inorganic devices."
Silicon based solutions are still our best option, as the presenter admits at the end.
What part of WestWorld is this?
excellet info keep it going
Hi, I am interested in this technology, and I want to setup 1000 sq metres of these solar ink panel so please give me some information regarding imports of these panels in large quantity..
Gonna have to rewatch because I was trying to pronounce her last name the whole time lol
Great talk
How about we put this on all our vehicles?
How efficient is it?
Where can I get my hands on a sample?
they don't know, it's a fake
Amazing robot!
SaintTrinianz as a german, that was my thought exactly
I just commented the same... So, it's not just me...
What does the free market say about solar?
let s do this now
sounds great...BUT now it is 2019 and in 2015 it was commercially put to use... why isnt it still not mass produced..... ooh let me guess.......indeed .... the commerce.... the big bucks greed comes first.....
Is TED becoming a product selling platform?
She seemed quite robotic. Great idea though. At MIT I saw a presentation where they could make solar cells with a 3-d printer. Maybe this is the future. Imagine designing your own solar cells.
- The introduction lingers a bit, I know the enviroment is an issue, don't depress me now.
- The Prius Effect suggests that aesthetics is a minor problem. People like evident bulky solar panels because it signals that they care for the enviroment.
- You say cost effective? My family just cannot afford to install solar panels. I computed the return of investment and it is in the decades. In fact, an hybrid solar and wind power solution for the house is better, we just don't have the space for the wind turbine. Waiting for cheaper technology makes more economic sense at the moment.
- Would this be cheaper? I don't know. Perhaps where you are. As I said, it makes sense to wait. At least my city uses geothermal energy, but a the country in general uses fossil fuels as main energy source.
You can try selling me the idea that we can change the wolrd starting from our homes... but no, I do not have the resources to produce cheap solar panels in my house. And politics? Teach me to dismantle the corporations behind fossil fuels and corruption, and hopefully without creating a militia.
That's a dislike from me. Fight me.
Listening to her speak, all it comes to mind is: "ve iz zi mikrofilm?" #germantalk
So 5 years later, where are they?
OPV's have been around for a while. the efficiency of OPV is very small (20%. another issue is photochemical decomposition. you put any polymer under the sun, and it will decompose over time, much faster than existing solar cells. it may have its place for aesthetic architecture or neat consumer goods, but it's a tough sell for actual power generation. if you want the building to be off grid, you need silicon.
She reminds me a lot like Shuri from Black Panther. Something about her.
I wonder what the life span is for this technology
she puts her shoe bacc on
If a solar cells stops working you do what? Take part of your building apart?
I think I'll stick with the modular panels for now thank you.
as simple as changing a window. Surely you dont need the specialists to do that.
I hope those are more efficient than solar panels made by sunpower.
And now put it in my phone
3:40 to 8:00 skip preachiness
I believe the majority of this and all ted talk audiences know enough about man’s devastating effect on our earth and it’s atmosphere in the last 100 yrs compared to anytime in earth’s natural history. We just need to apply the solutions NOW.
Notice how all the stock blunders appear on TED Talks lol..Remember Theranos
guys share something!!
About comparison with the credit at the begining... well.. greater part of the world is actually doing just that in their personal economics :P
EVERYONE LET'S WEAR UNPAIRED SHOES!!!
Wait...
Material efficiency is not equivalent to energy efficiency.
Looks AMAZING!
And if i understood correctly its carbon-based!
I want to cover my whole house with it!
Plastics are also carbon based so you might want wait for more information.
Nice pres using different shoes!
That's amazing

Elon Musk: **breathing intensifies**
... and loud laugh. No technical information provided so it can be considered as a scam
Cool idea, but one hack of a sales pitch
My lil brother sells solar for a living so naturally, I asked him about Elon Musk and solar cities beautiful cells. He told me they may look good but as far as bang for your buck they are terribly inefficient. For now they're just for people with more money than brains. Unless they are greatly improved they'll remain a toy for the rich. I couldn't help but notice her presentation failed to mention anything about their effieciency. Great Sales pitch
Dayuuum!!! these ladies in ted talk are so damn heavenly beautiful and intelligent. #TheSortOfLadiesIDreamOf
don't be gay dack
This amazing invention may be a nice improvement in environment, but the true solution is to change american consumist lifestyle, that spreads through he world.
Nobody and I mean nobody talks about the construction processes, including materials used to create that building, those materials in constructing solar cells in solar panels or the type of metal used to create a wind turbine, until we have that conversation all of this talk is meaningless and nothing will change.
Shut up and take my money!
and no questions about efficiency, cost, usability?... Oh, regular human being "I don't want to think, just rob me "
Points at a leather shoe...REALLY sustainable ! XD
Doesn't even tell you that most perovskites are using lead and that "inks" are actually deadly solvents...
Whatever...
