0:00:01.480,0:00:06.016 I thought I would start[br]with a very brief history of cities. 0:00:06.040,0:00:10.616 Settlements typically began[br]with people clustered around a well, 0:00:10.640,0:00:13.974 and the size of that settlement[br]was roughly the distance you could walk 0:00:13.998,0:00:15.936 with a pot of water on your head. 0:00:15.960,0:00:19.456 In fact, if you fly[br]over Germany, for example, 0:00:19.480,0:00:22.480 and you look down and you see[br]these hundreds of little villages, 0:00:22.504,0:00:24.240 they're all about a mile apart. 0:00:24.264,0:00:27.056 You needed easy access to the fields. 0:00:27.080,0:00:30.456 And for hundreds, even thousands of years, 0:00:30.480,0:00:33.056 the home was really the center of life. 0:00:33.080,0:00:35.656 Life was very small for most people. 0:00:35.680,0:00:41.776 It was a center of entertainment,[br]of energy production, of work, 0:00:41.800,0:00:43.016 a center of health care. 0:00:43.040,0:00:46.336 That's where babies were born[br]and people died. 0:00:46.360,0:00:51.216 Then, with industrialization,[br]everything started to become centralized. 0:00:51.240,0:00:55.256 You had dirty factories that were moved[br]to the outskirts of cities. 0:00:55.280,0:00:59.616 Production was centralized[br]in assembly plants. 0:00:59.640,0:01:03.216 You had centralized energy production. 0:01:03.240,0:01:04.935 Learning took place in schools. 0:01:04.959,0:01:07.920 Health care took place in hospitals. 0:01:09.000,0:01:11.016 And then you had networks that developed. 0:01:11.040,0:01:13.656 You had water, sewer networks 0:01:13.680,0:01:17.536 that allowed for this[br]kind of unchecked expansion. 0:01:17.560,0:01:21.176 You had separated functions, increasingly. 0:01:21.200,0:01:22.936 You had rail networks 0:01:22.960,0:01:25.776 that connected residential,[br]industrial, commercial areas. 0:01:25.800,0:01:27.416 You had auto networks. 0:01:27.440,0:01:30.696 In fact, the model was really,[br]give everybody a car, 0:01:30.720,0:01:32.056 build roads to everything, 0:01:32.080,0:01:34.536 and give people a place to park[br]when they get there. 0:01:34.560,0:01:36.256 It was not a very functional model. 0:01:36.280,0:01:38.656 And we still live in that world, 0:01:38.680,0:01:40.816 and this is what we end up with. 0:01:40.840,0:01:42.896 So you have the sprawl of LA, 0:01:42.920,0:01:45.096 the sprawl of Mexico City. 0:01:45.120,0:01:48.216 You have these unbelievable[br]new cities in China, 0:01:48.240,0:01:50.576 which you might call tower sprawl. 0:01:50.600,0:01:51.936 They're all building cities 0:01:51.960,0:01:54.896 on the model that we invented[br]in the '50s and '60s, 0:01:54.920,0:01:56.936 which is really obsolete, I would argue, 0:01:56.960,0:01:59.246 and there are hundreds[br]and hundreds of new cities 0:01:59.270,0:02:01.326 that are being planned all over the world. 0:02:01.350,0:02:05.376 In China alone, 300 million people,[br]some say 400 million people, 0:02:05.400,0:02:07.736 will move to the city[br]over the next 15 years. 0:02:07.760,0:02:10.256 That means building the equivalent 0:02:10.280,0:02:13.096 of the entire built infrastructure[br]of the US in 15 years. 0:02:13.120,0:02:14.336 Imagine that. 0:02:14.360,0:02:19.016 And we should all care about this[br]whether you live in cities or not. 0:02:19.040,0:02:22.616 Cities will account for 90 percent[br]of the population growth, 0:02:22.640,0:02:27.416 80 percent of the global CO2,[br]75 percent of energy use, 0:02:27.440,0:02:29.936 but at the same time[br]it's where people want to be, 0:02:29.960,0:02:31.536 increasingly. 0:02:31.560,0:02:34.376 More than half the people[br]now in the world live in cities, 0:02:34.400,0:02:37.096 and that will just continue to escalate. 0:02:37.120,0:02:40.736 Cities are places of celebration,[br]personal expression. 0:02:40.760,0:02:44.056 You have the flash mobs[br]of pillow fights that -- 0:02:44.080,0:02:46.176 I've been to a couple. They're quite fun. 0:02:46.200,0:02:47.416 You have -- 0:02:47.440,0:02:48.696 (Laughter) 0:02:48.720,0:02:51.536 Cities are where most[br]of the wealth is created, 0:02:51.560,0:02:55.256 and particularly in the developing world,[br]it's where women find opportunities. 0:02:55.280,0:02:58.696 That's a lot of the reason[br]why cities are growing very quickly. 0:02:58.720,0:03:01.336 Now there's some trends[br]that will impact cities. 0:03:01.360,0:03:04.256 First of all, work is becoming[br]distributed and mobile. 0:03:04.280,0:03:07.896 The office building is basically obsolete[br]for doing private work. 0:03:07.920,0:03:12.296 The home, once again,[br]because of distributed computation -- 0:03:12.320,0:03:14.336 Communication is becoming[br]a center of life, 0:03:14.360,0:03:18.536 so it's a center of production[br]and learning and shopping and health care 0:03:18.560,0:03:21.336 and all of these things[br]that we used to think of 0:03:21.360,0:03:24.176 as taking place outside of the home. 0:03:24.200,0:03:27.176 And increasingly,[br]everything that people buy, 0:03:27.200,0:03:28.536 every consumer product, 0:03:28.560,0:03:31.496 in one way or another,[br]can be personalized. 0:03:31.520,0:03:33.936 And that's a very important[br]trend to think about. 0:03:33.960,0:03:36.576 So this is my image[br]of the city of the future. 0:03:37.059,0:03:39.416 (Laughter) 0:03:39.440,0:03:41.696 In that it's a place for people, you know. 0:03:41.720,0:03:44.416 Maybe not the way people dress, but -- 0:03:44.440,0:03:45.869 You know, the question now is, 0:03:45.893,0:03:49.336 how can we have all the good things[br]that we identify with cities 0:03:49.360,0:03:51.176 without all the bad things? 0:03:51.200,0:03:52.416 This is Bangalore. 0:03:52.440,0:03:56.496 It took me a couple of hours[br]to get a few miles in Bangalore last year. 0:03:56.520,0:03:59.056 So with cities, you also have[br]congestion and pollution 0:03:59.080,0:04:01.736 and disease and all these negative things. 0:04:01.760,0:04:03.976 How can we have the good stuff[br]without the bad? 0:04:04.000,0:04:06.572 So we went back and started looking[br]at the great cities 0:04:06.596,0:04:08.696 that evolved before the cars. 0:04:08.720,0:04:13.056 Paris was a series of these[br]little villages that came together, 0:04:13.080,0:04:14.976 and you still see that structure today. 0:04:15.000,0:04:17.953 The 20 arrondissements of Paris[br]are these little neighborhoods. 0:04:17.977,0:04:22.696 Most of what people need in life[br]can be within a five- or 10-minute walk. 0:04:22.720,0:04:25.936 And if you look at the data,[br]when you have that kind of a structure, 0:04:25.960,0:04:27.656 you get a very even distribution 0:04:27.680,0:04:31.056 of the shops and the physicians[br]and the pharmacies 0:04:31.080,0:04:32.976 and the cafes in Paris. 0:04:33.000,0:04:35.936 And then you look at cities[br]that evolved after the automobile, 0:04:35.960,0:04:37.696 and it's not that kind of a pattern. 0:04:37.720,0:04:40.736 There's very little[br]that's within a five-minute walk 0:04:40.760,0:04:43.056 of most areas of places like Pittsburgh. 0:04:43.080,0:04:44.336 Not to pick on Pittsburgh, 0:04:44.360,0:04:48.896 but most American cities[br]really have evolved this way. 0:04:48.920,0:04:51.096 So we said, well,[br]let's look at new cities, 0:04:51.120,0:04:55.336 and we're involved in a couple[br]of new city projects in China. 0:04:55.360,0:04:57.816 So we said, let's start[br]with that neighborhood cell. 0:04:57.840,0:04:59.736 We think of it as a compact urban cell. 0:04:59.760,0:05:03.336 So provide most of what most people want[br]within that 20-minute walk. 0:05:03.360,0:05:06.896 This can also be[br]a resilient electrical microgrid, 0:05:06.920,0:05:10.496 community heating, power,[br]communication networks, etc. 0:05:10.520,0:05:12.296 can be concentrated there. 0:05:12.320,0:05:15.176 Stewart Brand would put[br]a micronuclear reactor 0:05:15.200,0:05:17.176 right in the center, probably. 0:05:17.200,0:05:18.656 And he might be right. 0:05:18.680,0:05:22.216 And then we can form,[br]in effect, a mesh network. 0:05:22.240,0:05:25.856 It's something of an Internet[br]typology pattern, 0:05:25.880,0:05:28.376 so you can have a series[br]of these neighborhoods. 0:05:28.400,0:05:29.856 You can dial up the density -- 0:05:29.880,0:05:32.376 about 20,000 people per cell,[br]if it's Cambridge. 0:05:32.400,0:05:34.936 Go up to 50,000 if it's Manhattan density. 0:05:34.960,0:05:37.056 You connect everything with mass transit 0:05:37.080,0:05:41.336 and you provide most of what most people[br]need within that neighborhood. 0:05:41.360,0:05:44.576 You can begin to develop[br]a whole typology of streetscapes 0:05:44.600,0:05:47.656 and the vehicles that can go on them. 0:05:47.680,0:05:50.096 I won't go through all of them.[br]I'll just show one. 0:05:50.120,0:05:54.016 This is Boulder. It's a great example[br]of kind of a mobility parkway, 0:05:54.040,0:05:56.776 a superhighway for joggers and bicyclists, 0:05:56.800,0:05:59.324 where you can go from one end[br]of the city to the other 0:05:59.348,0:06:01.096 without crossing the street, 0:06:01.120,0:06:04.896 and they also have bike-sharing,[br]which I'll get into in a minute. 0:06:04.920,0:06:07.096 This is even a more interesting solution 0:06:07.120,0:06:08.336 in Seoul, Korea. 0:06:08.360,0:06:10.776 They took the elevated highway,[br]they got rid of it, 0:06:10.800,0:06:14.416 they reclaimed the street,[br]the river down below, 0:06:14.440,0:06:15.816 below the street, 0:06:15.840,0:06:18.176 and you can go from one end[br]of Seoul to the other 0:06:18.200,0:06:21.856 without crossing a pathway for cars. 0:06:21.880,0:06:25.200 The High Line in Manhattan[br]is very similar. 0:06:26.360,0:06:30.536 You have these rapidly emerging[br]bike lanes all over the world. 0:06:30.560,0:06:32.216 I lived in Manhattan for 15 years. 0:06:32.240,0:06:34.496 I went back a couple of weekends ago, 0:06:34.520,0:06:40.096 took this photograph of these fabulous[br]new bike lanes that they have installed. 0:06:40.120,0:06:42.936 They're still not to where Copenhagen is, 0:06:42.960,0:06:46.376 where something like 42 percent[br]of the trips within the city 0:06:46.400,0:06:47.616 are by bicycle. 0:06:47.640,0:06:51.416 It's mostly just because they have[br]fantastic infrastructure there. 0:06:51.440,0:06:54.136 We actually did exactly[br]the wrong thing in Boston. 0:06:54.160,0:06:56.216 The Big Dig -- 0:06:56.240,0:06:58.736 (Laughter) 0:06:58.760,0:07:02.776 So we got rid of the highway[br]but we created a traffic island, 0:07:02.800,0:07:07.496 and it's certainly not a mobility pathway[br]for anything other than cars. 0:07:07.520,0:07:10.256 Mobility on demand is something[br]we've been thinking about, 0:07:10.280,0:07:13.576 so we think we need an ecosystem[br]of these shared-use vehicles 0:07:13.600,0:07:15.696 connected to mass transit. 0:07:15.720,0:07:18.776 These are some of the vehicles[br]that we've been working on. 0:07:18.800,0:07:20.456 But shared use is really key. 0:07:20.480,0:07:24.376 If you share a vehicle, you can have[br]at least four people use one vehicle, 0:07:24.400,0:07:26.256 as opposed to one. 0:07:26.280,0:07:31.200 We have Hubway here in Boston,[br]the VĂ©lib' system in Paris. 0:07:32.760,0:07:37.016 We've been developing,[br]at the Media Lab, this little city car 0:07:37.040,0:07:40.216 that is optimized[br]for shared use in cities. 0:07:40.240,0:07:43.616 We got rid of all the useless things[br]like engines and transmissions. 0:07:43.640,0:07:45.616 We moved everything to the wheels, 0:07:45.640,0:07:47.016 so you have the drive motor, 0:07:47.040,0:07:49.536 the steering motor, the breaking --[br]all in the wheel. 0:07:49.560,0:07:52.736 That left the chassis unencumbered,[br]so you can do things like fold, 0:07:52.760,0:07:58.416 so you can fold this little vehicle up[br]to occupy a tiny little footprint. 0:07:58.440,0:08:01.896 This was a video that was[br]on European television last week 0:08:01.920,0:08:07.536 showing the Spanish Minister of Industry[br]driving this little vehicle, 0:08:07.560,0:08:09.376 and when it's folded, it can spin. 0:08:09.400,0:08:12.656 You don't need reverse.[br]You don't need parallel parking. 0:08:12.680,0:08:14.296 You just spin and go directly in. 0:08:14.320,0:08:15.896 (Laughter) 0:08:15.920,0:08:18.696 So we've been working[br]with a company to commercialize this. 0:08:18.720,0:08:21.816 My PhD student Ryan Chin[br]presented these early ideas 0:08:21.840,0:08:24.496 two years ago at a TEDx conference. 0:08:24.520,0:08:27.016 So what's interesting is, 0:08:27.040,0:08:29.856 then if you begin to add[br]new things to it, like autonomy, 0:08:29.880,0:08:32.655 you get out of the car,[br]you park at your destination, 0:08:32.679,0:08:36.496 you pat it on the butt, it goes[br]and it parks itself, it charges itself, 0:08:36.520,0:08:41.096 and you can get something[br]like seven times as many vehicles 0:08:41.120,0:08:44.456 in a given area as conventional cars, 0:08:44.480,0:08:46.056 and we think this is the future. 0:08:46.080,0:08:49.776 Actually, we could do this today.[br]It's not really a problem. 0:08:49.800,0:08:53.336 We can combine shared use[br]and folding and autonomy 0:08:53.360,0:08:56.656 and we get something[br]like 28 times the land utilization 0:08:56.680,0:08:58.336 with that kind of strategy. 0:08:58.360,0:09:00.218 One of our graduate students then says, 0:09:00.242,0:09:04.376 well, how does a driverless car[br]communicate with pedestrians? 0:09:04.400,0:09:06.576 You have nobody to make eye contact with. 0:09:06.600,0:09:08.736 You don't know[br]if it's going to run you over. 0:09:08.760,0:09:10.336 So he's developing strategies 0:09:10.360,0:09:12.936 so the vehicle can communicate[br]with pedestrians, so -- 0:09:12.960,0:09:14.376 (Laughter) 0:09:14.400,0:09:17.336 So the headlights are eyeballs,[br]the pupils can dilate, 0:09:17.360,0:09:21.536 we have directional audio,[br]we can throw sound directly at people. 0:09:21.560,0:09:23.016 What I love about this project 0:09:23.040,0:09:26.656 is he solved a problem[br]that doesn't exist yet, so -- 0:09:26.680,0:09:29.616 (Laughter) 0:09:29.640,0:09:33.496 We also think that we can[br]democratize access to bike lanes. 0:09:33.520,0:09:37.416 You know, bike lanes are mostly used[br]by young guys in stretchy pants. So -- 0:09:37.440,0:09:38.816 (Laughter) 0:09:38.840,0:09:42.656 We think we can develop a vehicle[br]that operates on bike lanes, 0:09:42.680,0:09:47.656 accessible to elderly and disabled,[br]women in skirts, businesspeople, 0:09:47.680,0:09:50.256 and address the issues[br]of energy congestion, mobility, 0:09:50.280,0:09:52.536 aging and obesity simultaneously. 0:09:52.560,0:09:53.776 That's our challenge. 0:09:53.800,0:09:56.656 This is an early design[br]for this little three-wheel. 0:09:56.680,0:09:58.176 It's an electronic bike. 0:09:58.200,0:10:01.936 You have to pedal[br]to operate it in a bike lane, 0:10:01.960,0:10:04.576 but if you're an older person,[br]that's a switch. 0:10:04.600,0:10:08.376 If you're a healthy person, you might[br]have to work really hard to go fast. 0:10:08.400,0:10:10.696 You can dial in 40 calories[br]going into work 0:10:10.720,0:10:13.376 and 500 going home,[br]when you can take a shower. 0:10:13.400,0:10:17.656 We hope to have that built this fall. 0:10:17.680,0:10:21.056 Housing is another area[br]where we can really improve. 0:10:21.080,0:10:23.256 Mayor Menino in Boston says 0:10:23.280,0:10:26.216 lack of affordable housing[br]for young people 0:10:26.240,0:10:28.976 is one of the biggest[br]problems the city faces. 0:10:29.000,0:10:31.736 Developers say, OK,[br]we'll build little teeny apartments. 0:10:31.760,0:10:36.016 People say, we don't really want to live[br]in a little teeny conventional apartment. 0:10:36.040,0:10:40.096 So we're saying, let's build[br]a standardized chassis, 0:10:40.120,0:10:41.456 much like our car. 0:10:41.480,0:10:46.576 Let's bring advanced technology[br]into the apartment, 0:10:46.600,0:10:49.136 technology-enabled infill, 0:10:49.160,0:10:54.136 give people the tools[br]within this open-loft chassis 0:10:54.160,0:10:55.976 to go through a process of defining 0:10:56.000,0:10:58.936 what their needs[br]and values and activities are, 0:10:58.960,0:11:02.536 and then a matching algorithm[br]will match a unique assembly 0:11:02.560,0:11:04.536 of integrated infill components, 0:11:04.560,0:11:09.656 furniture, and cabinetry,[br]that are personalized to that individual, 0:11:09.680,0:11:11.056 and they give them the tools 0:11:11.080,0:11:13.096 to go through the process[br]and to refine it, 0:11:13.120,0:11:15.496 and it's something like working[br]with an architect, 0:11:15.520,0:11:16.776 where the dialogue starts 0:11:16.800,0:11:21.480 when you give an alternative[br]to a person to react to. 0:11:22.800,0:11:27.496 Now, the most interesting[br]implementation of that for us 0:11:27.520,0:11:29.576 is when you can begin[br]to have robotic walls, 0:11:29.600,0:11:33.416 so your space can convert[br]from exercise to a workplace, 0:11:33.440,0:11:35.176 if you run a virtual company. 0:11:35.200,0:11:36.350 You have guests over, 0:11:36.374,0:11:40.056 you have two guest rooms[br]that are developed. 0:11:40.080,0:11:43.936 You have a conventional[br]one-bedroom arrangement 0:11:43.960,0:11:45.164 when you need it. 0:11:45.188,0:11:46.716 Maybe that's most of the time. 0:11:46.740,0:11:47.896 You have a dinner party. 0:11:47.920,0:11:51.976 The table folds out to fit 16 people[br]in otherwise a conventional one-bedroom, 0:11:52.000,0:11:53.616 or maybe you want a dance studio. 0:11:53.640,0:11:57.056 I mean, architects have been thinking[br]about these ideas for a long time. 0:11:57.080,0:11:59.296 What we need to do now, 0:11:59.320,0:12:04.816 develop things that can scale[br]to those 300 million Chinese people 0:12:04.840,0:12:08.976 that would like to live in the city,[br]and very comfortably. 0:12:09.000,0:12:11.296 We think we can make[br]a very small apartment 0:12:11.320,0:12:16.656 that functions as if it's twice as big[br]by utilizing these strategies. 0:12:16.680,0:12:20.216 I don't believe in smart homes.[br]That's sort of a bogus concept. 0:12:20.240,0:12:23.456 I think you have to build dumb homes[br]and put smart stuff in it. 0:12:23.480,0:12:25.736 (Laughter) 0:12:25.760,0:12:31.176 And so we've been working[br]on a chassis of the wall itself. 0:12:31.200,0:12:32.736 You know, standardized platform 0:12:32.760,0:12:35.536 with the motors and the battery[br]when it operates, 0:12:35.560,0:12:40.096 little solenoids that will lock it[br]in place and get low-voltage power. 0:12:40.120,0:12:41.936 We think this can all be standardized, 0:12:41.960,0:12:45.896 and then people can personalize the stuff[br]that goes into that wall, 0:12:45.920,0:12:48.616 and like the car, we can integrate[br]all kinds of sensing 0:12:48.640,0:12:51.016 to be aware of human activity, 0:12:51.040,0:12:54.336 so if there's a baby[br]or a puppy in the way, 0:12:54.360,0:12:55.576 you won't have a problem. 0:12:55.600,0:12:56.616 (Laughter) 0:12:56.640,0:12:59.376 So the developers say,[br]well, this is great. 0:12:59.400,0:13:03.456 OK, so if we have a conventional building,[br]we have a fixed envelope, 0:13:03.480,0:13:05.536 maybe we can put in 14 units. 0:13:05.560,0:13:07.656 If they function[br]as if they're twice as big, 0:13:07.680,0:13:09.216 we can get 28 units in. 0:13:09.240,0:13:11.265 That means twice as much parking, though. 0:13:11.289,0:13:12.596 Parking's really expensive. 0:13:12.620,0:13:15.256 It's about 70,000 dollars per space 0:13:15.280,0:13:19.056 to build a conventional parking spot[br]inside a building. 0:13:19.080,0:13:22.656 So if you can have folding and autonomy, 0:13:22.680,0:13:25.096 you can do that[br]in one-seventh of the space. 0:13:25.120,0:13:27.296 That goes down to 10,000 dollars per car, 0:13:27.320,0:13:28.896 just for the cost of the parking. 0:13:28.920,0:13:32.856 You add shared use,[br]and you can even go further. 0:13:32.880,0:13:35.936 We can also integrate[br]all kinds of advanced technology 0:13:35.960,0:13:37.176 through this process. 0:13:37.200,0:13:40.336 There's a path to market[br]for innovative companies 0:13:40.360,0:13:42.016 to bring technology into the home. 0:13:42.040,0:13:44.616 In this case, a project[br]we're doing with Siemens. 0:13:44.640,0:13:47.216 We have sensors on all[br]the furniture, all the infill, 0:13:47.240,0:13:49.936 that understands where people are[br]and what they're doing. 0:13:49.960,0:13:51.656 Blue light is very efficient, 0:13:51.680,0:13:55.816 so we have these tunable[br]24-bit LED lighting fixtures. 0:13:55.840,0:13:59.976 It recognizes where the person is,[br]what they're doing, 0:14:00.000,0:14:04.216 fills out the light when necessary[br]to full spectrum white light, 0:14:04.240,0:14:10.456 and saves maybe 30, 40 percent[br]in energy consumption, we think, 0:14:10.480,0:14:15.936 over even conventional[br]state-of-the-art lighting systems. 0:14:15.960,0:14:19.376 This just shows you the data[br]that comes from the sensors 0:14:19.400,0:14:21.096 that are embedded in the furniture. 0:14:21.120,0:14:23.936 We don't really believe in cameras[br]to do things in homes. 0:14:23.960,0:14:27.936 We think these little wireless sensors[br]are more effective. 0:14:27.960,0:14:30.216 We think we can also personalize sunlight. 0:14:30.240,0:14:32.907 That's sort of the ultimate[br]personalization in some ways. 0:14:32.931,0:14:35.896 So we've looked at articulating[br]mirrors of the facade 0:14:35.920,0:14:39.816 that can throw shafts of sunlight[br]anywhere into the space, 0:14:39.840,0:14:42.216 therefore allowing you[br]to shade most of the glass 0:14:42.240,0:14:44.456 on a hot day like today. 0:14:44.480,0:14:46.336 In this case, she picks up her phone, 0:14:46.360,0:14:50.936 she can map food preparation[br]at the kitchen island 0:14:50.960,0:14:53.376 to a particular location of sunlight. 0:14:53.400,0:14:58.576 An algorithm will keep it in that location[br]as long as she's engaged in that activity. 0:14:58.600,0:15:01.517 This can be combined[br]with LED lighting as well. 0:15:02.760,0:15:04.856 We think workplaces should be shared. 0:15:04.880,0:15:07.690 I mean, this is really[br]the workplace of the future, I think. 0:15:07.714,0:15:09.210 This is Starbucks, you know. 0:15:09.234,0:15:10.416 Maybe a third -- 0:15:10.440,0:15:12.696 And you see everybody[br]has their back to the wall 0:15:12.720,0:15:14.720 and they have food and coffee down the way 0:15:14.744,0:15:17.176 and they're in their own[br]little personal bubble. 0:15:17.200,0:15:19.896 We need shared spaces[br]for interaction and collaboration. 0:15:19.920,0:15:22.136 We're not doing a very good job with that. 0:15:22.160,0:15:26.216 At the Cambridge Innovation Center,[br]you can have shared desks. 0:15:26.240,0:15:30.936 I've spent a lot of time in Finland[br]at the design factory of Aalto University, 0:15:30.960,0:15:35.656 where the they have a shared shop[br]and shared fab lab, shared quiet spaces, 0:15:35.680,0:15:39.816 electronics spaces, recreation places. 0:15:39.840,0:15:43.296 We think ultimately,[br]all of this stuff can come together, 0:15:43.320,0:15:47.016 a new model for mobility,[br]a new model for housing, 0:15:47.040,0:15:49.336 a new model for how we live and work, 0:15:49.360,0:15:52.176 a path to market[br]for advanced technologies. 0:15:52.200,0:15:55.105 But in the end, the main thing[br]we need to focus on are people. 0:15:55.129,0:15:56.696 Cities are all about people. 0:15:56.720,0:15:58.736 They're places for people. 0:15:58.760,0:16:01.216 There's no reason[br]why we can't dramatically improve 0:16:01.240,0:16:03.536 the livability and creativity of cities 0:16:03.560,0:16:07.456 like they've done in Melbourne[br]with the laneways 0:16:07.480,0:16:12.056 while at the same time[br]dramatically reducing CO2 and energy. 0:16:12.080,0:16:15.416 It's a global imperative.[br]We have to get this right. 0:16:15.440,0:16:16.656 Thank you. 0:16:16.680,0:16:21.200 (Applause)
