The Race for Black Gold: How to Live Without Oil? | Full Documentary

Finalement le prix du carburant baisse, a t-on trouvé de nouvelles sources ?

Il est certain que la fracturation hydraulique pourrira les sources d'eau douce.
Que vaut-il mieux ? De l'eau potable et des boeufs où des voitures et plus d'eau fraîche ?

What's the name of the song in the beginning ?

There is no shortage of oil!

De base jsuis optimiste, je crois en nous j'ai des lunettes rose en voyant que la majorité des gens veulent faire bien mais j'ai aussi un côté pragmatique et je me dit qu'en voyant les actions des personnes qui gouvernent ( dirigeant étatique et industrielle ) je me dit avec tristesse que tant qu'on ne c'est pas pris le mur et qu'il n'y pas des morts en masse a le feu un peu partout sur terre, j'ai peur que le changement ne se fera pas.. ça fait 50ans qu'on sait tout ça et pourtant.. ça parle encore d'argent, de manque a gagné, de business, etc..
C'est triste je continue a y croire mais ça fait peur et mal au coeur
Continuons a faire attention a nos consommations a notre échelles c'est le mieux.. peut être que le changement viendras de là..

PS: et je dit ça sans me mentir a moi même parce que il n'y a pas que les individus qui polluent, les industries, l'import export, les cargo, les avions bref ont n'est pas les dindons de la farce mais restons attentifs 👍👍 force a vous

You don't need to use drinking water you can use reclaimed water or river water

Excellent documentary.. it’s the most important subject of our civilisation.. very well put together.. the ai voice was really painful to listen too though.. hopefully you will get a real person to narrate the next one .. I think that we will eventually have to go with using plants as solar collectors .. for example massive water hyacinth farms that turn waste water and the sun’s energy into methane gas and at the same time producing food and wildlife habitat and totally none polluting and using waste land like deserts .. but that will require human evaluation to get to that level of thinking..

Oil is also the source of asphalt. Spaniards driving their cars on gravel roads?😂

The only way you get oil is from oil.

We have giant landfills covering this earth, encased petroleum products covered with dirt, and later planted over. In a million years, this pocket of petroleum products sinks miles into the earth…..

The next civilization finds crued oil.

Now I understand people who used to America can’t extract its oil. Because its so toxic to extract oil from the ground

"Immediately, if not sooner." ~ Trump.

Technology may have advanced enough to release civilization from the confines of the second law of thermodynamics.

These confines were imposed during Victorian England's scientific and religious cultural fascination with steam engines.

The second law is behind modern refgeration needing electrical energy to compress the refrigerent to force it to release as waste the heat that it has removed from the refrigerator's service interior in the cooling part of the refrigerent's circulation. There is also discarded heat from mechanical friction and electrical resistance. The total released and discarded heat minus the removed heat equal the electrical input but the attached conversion of electricity into heat is forced.

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

It makes more sense that refrigerators should yield electricity because energy is widely known to change form with no ultimate path of energy gain or loss being found. Therefore any form of fully recyclable energy can be cycled endlessly in any quantity.

In an extreme case senario, full heat recycling, all electric, very isolated underground, undersea, or space communities would be highly survivable with self sufficient EMP resistant LED light banks, automated vertical farms, thaw resistant frozen food storehouses, factories, dwellings, and self contained elevators and horizontal transports.

In a flourishing civillization senario, small self sufficient electric or cooling devices of many kinds and styles like lamps, smartphones, hotplates, water heaters, cooler chests, fans, radios, TVs, cameras, security devices, robot test equipment, scales, transaction terminals, wall clocks, open or ciosed for business luminus signs, power hand tools, ditch diggers, pumps, and personal transports, would be available for immediate use incrementally anywhere as people see fit.

Some equipment groups could be consolidated on local networks.

If a high majority thinks our civilization should geoengineer gigatons or
teratons of carbon dioxide out of our environment, instalations using devices that convert ambient heat into electricity can hypothetically be scaled up do it with a choice of comsequences including many beneficial ones.

Energy sensible refrigerators that absorb heat and yield electricity would complement computers as computing consumes electricity and yields heat. Computing would be free. Chips could have energy recycling built in.

A simple rectifier crystal can, iust short of a replicatable long term demonstration of a powerful prototype, almost certainly filter the random thermal motioren 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, which is 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. The maximum energy is converted from ambient heat to productive electricity when the electrical load is matched to the array impeadence.

Matched impeadence output (watts) is k (Boltźman's constant), one point three eight x 10^ minus 23, times T (temperature Kelvin) times bandwidth (0 Hz to a natural limit ~2 THz @ 290 K) times rectification halving and nanowatt power level rectification efficiency, times the number of diodes in the array.

For reference, there are a billion cells of 1000 square nanometer area each per square millimeter, 100 billion per square centimeter.

Order is imposed on the random thermal motion of electrons by the structual orderlyness of a diode array made of diodes made within a slab:
____________________  – Out
  🔻🔻🔻🔻🔻🔻🔻
____________________ + Out

All the P type semiconductor anodes abut a metal conductive plane deposited on the top face of the slab with nonrectifying joins; all the N type semiconductor cathodes abut the bottom face. 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.

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 (N type)on one side from a ohmic contact end to a junction where the additive is suddenly and completely changed to boron (P type) with minimal disturbance of the crystal lattice. 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 holes which are 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 noise transients, where mobile electrons move from the phosphorus added side to the boron added side ride transient extra conductivity so the forward moving  electrons are preferentally filtered into the external circuit. Mobile 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. Inside the diode, heat is absorbed: outside the diode, to exactly the same extent, an attached electrical circuit is energized. The voltage of a diode array is likely to be small so many similar arrays need to be put in series to build higher voltage. 

Understanding diodes is one way to become convinced that Johnson Nyquest thermal electrical noise can be rectified and aggregated. Self assembling development teams may find many ways to accomplish this wide mission. Taxonomically there should be many ways ways to convert heat directly into electricity.

A practical device may use an array of Au needles in a SiO2 matrix abutting N type GaAs. These were made in the 1970s when registration technology was poor so it was easier to fabricate arrays and select one diode than just make one diode.

There are other plausible breeches of the second law of thermodynamics. Hopefully a lot of people will join in expanding the breech. Please share the successes or setbacks of your efforts.

These devices would probably become segmented commodities sold with minimal margin over supply cost. They would be manufactured by advanced automation that does not need financial incentive. Applicable best practices would be adopted. Business details would be open public knowledge. Associated people should move as negotiated and freely and honestly talk. Commerce would be a planetary scale unified conglomerate of diverse local cooperatives. There is no need of wealth extracting top commanders. We do not need often token philanthropy from the top if the wide majority of people can afford to be generous.
