Future Cities: The Quest for Sustainable Urban Living | SLICE EARTH | FULL DOC

Imagine the future – new, smart, ecological and hyper-connected cities, nourishing the hope for more sustainable lifestyles… This is not science-fiction, but the adventure of building the cities of tomorrow. With these full-scale prototypes, scientists are experimenting green and technological systems to answer the two major challenges of future societies : on the one hand, the energetic issue, with the upcoming shortage of resources, and on the other hand, the demographic conundrum threatening cities with its skyrocketing figures : the number of city dwellers (today around 3.6 billions) is likely to reach 6.3 billions in 2050 – 50 to 70% of the world population.

From Songdo (South Korea) to King Abdullah Economic City (Saudi Arabia), we will follow the experts who design these ideal cities from scratch, developing methods to improve the efficiency of urban networks (transportation, energy…). A dream for some, a nightmare for others : this hyper-connected utopian model keeps asking the question of surveillance and personal data protection. Are futuristic cities a Big Brother-like vision, jeopardizing individual liberties ?

I was hoping they would’ve talked about earthships, intentional communities, homesteading, food forests, idk? That was not ground breaking at all. Those ‘solutions’ (more like mitigation) are only applicable to the wealthy and barely scalable by dictatorships let alone somewhere actually administered by the residents.

How old is this video ?? It's ancient ! There are people in the footage who are in jail now or have died many years ago. This is totally irrelevant information in todays world. Are You just chasing 'clicks'??

《 Arrays of nanodiodes promise full conservation of energy》

A simple rectifier crystal can, iust short of a replicatable long term demonstration of a powerful prototype, almost certainly filter the random thermal motion of electrons or discrete positiive charged voids called holes so the electric current flowing in one direction predominates. At low system voltage a filtrate of one polarity predominates only a little but there is always usable electrical power derived from the source Johnson Nyquest thermal electrical noise. This net electrical filtrate can be aggregated in a group of separate diodes in consistent alignment parallel creating widely scalable electrical power. As the polarity filtered electrical energy is exported, the amount of thermal energy in the group of diodes decreases. This group cooling will draw heat in from the surrounding ambient heat at a rate depending on the filtering rate and thermal resistance between the group and ambient gas, liquid, or solid warmer than absolute zero. There is a lot of ambient heat on our planet, more in equatorial dry desert summer days and less in polar desert winter nights.

Refrigeration by the principle that energy is conserved should produce electricity instead of consuming it.

Focusing on explaining the electronic behavior of one composition of simple diode, a near flawless crystal of silicon is modified by implanting a small amount of phosphorus on one side from a ohmic contact end to a junction where the additive is suddenly and completely changed to boron with minimal disturbance of the crystal pattern. The crystal then continues to another ohmic contact.

A region of high electrical resistance forms at the junction in this type of diode when the phosphorous near the ĵunction donates electrons that are free to move elsewhere while leaving phosphorus ions held in the crystal while the boron donates a hole which is similalarly free to move. The two types of mobile charges mutually clear each other away near the junction leaving little electrical conductivity. An equlibrium width of this region is settled between the phosphorus, boron, electrons, and holes. Thermal noise is beyond steady state equlibrium. Thermal transients where mobile electrons move from the phosphorus added side to the boron added side ride transient extra conductivity so they are filtered into the external circuit. Electrons are units of electric current. They lose their thermal energy of motion and gain electromotive force, another name for voltage, as they transition between the junction and the array electrical tap.

LNG is not cleaner, it emits methane, which is much worse for the environment.

7:10 HOLY CRAP! They have no idea how to plan a city! Are they all Sim City addicts or something?

Cities are anything but sustainable and were created in the 1950s mostly with massive forced rural exodus

Cities create alienation, segregation, exploitation, consumerism, unawareness, etc, people should return to the land

We are all slaves 🌐 so to hear you talk about governments and world economic is so 🫤

In the building there are 75 to 85 protocols and they have good reasons NOT to talk to each other. Just like your hands do not talk with your feet. Your hands and feet communicate with your brain.

It is correct that the HVAC system does not talk to the lighting systems and fire system. What is the reason the lighting system talk with the fire system? This is the horrible illustration of the smart city. These systems are quite dumb and not AI enabled. Thus the IoT interfaces can be built with the central management systems that powered by AI system for smart facility management.

IoT devices do not need to talk with each other.
