Depletion: oil shortage early in 2015?

[dedeleco]

In 1973 there was the oil shock and it was announced in 1974 and certain thatwe would have no more oil in the year 2000 justifying the start of our nuclear power plants to save us from the disappearance of oil!
We continue to burn this oil even more than before in 2010!

Since fossil fuels come from photosynthesis for at least 400millions of years and this photosynthesis completely renews the oxygen of the atmosphere (that we breathe) all the 200 000ans about, leaving a similar amount of biological carbon in number of atoms that gives oil, coal, methane, and other fuels accumulated in the earth, we have in the earth a huge supply of fuel capable of burning 400xMillions / 200000 = 2000 times all the oxygen of our atmosphere !!
So even if we recover a tiny portion of this reserve (it disappears partly in the depths with the continental drift), we will not run out of fuel to burn all the oxygen we breathe !!!
Also, even if the CO2 heats less than feared, we will not be able to wait for the end of fossil fuels to stop burning them, if we want to breathe!

It is not false. At the same time my little finger tells me that the Co2 present in the atmosphere is the food of plants that produce oxygen. But of course we can not deduce that oil would be econological
But one thing crumples me in your reasoning: you would like to say that the peak oil is not about to arrive. And even that it will never happen, because if it happened there would be no oxygen in the atmosphere, right?

develop urban power plants with wood

I heard that wood was the most polluting and the most dangerous for health ...? And that it would be better only in terms of Co2:

I would say rather like Vivi:

To not pollute should therefore all have its mini hydraulic power station

Good no, not to pollute, do not consume ... and therefore isolate!

I draw your attention to the fact that Désertec is not the only solution to replace oil or nuclear!
Remember that Desertec will only cover 15% of the European demand, which leaves a nice part to the nuclear!
One of the best solutions for massive energy production would be the vortex tower.

This is the only technology that, in addition to providing energy at low cost, can provide food and drink!
Energy: a tower of 300m is expected to be around 400 MW at 1000 MW
To drink: condensation in the tower can be captured, so fresh water to the key.
To eat: the peripheral greenhouses can be used for organic agriculture on 1 / 3 of their surface according to the latitude.
The cost of such a tower would be more 3 times lower than a nuclear slice .... no pollution, no waste, life of more than a century ....
Such a device coupled with a European solar project (Eurotrec) would be one of the best solutions.

To the fixed objective of 15% we must add the share of production intended for native needs. But the potential is greater, there is no limit. If the politicians want it, it is the global needs that could be covered without problems thanks to the deserts (I put aside the debate of society and the biodiversity of the deserts, if it would represent a crucial problem).

This vortex tower works according to what principle Sen-no-sen, I never heard about it as a finalized project. Do you speak in the conditional, does that mean that it does not exist yet?

Hello!
I put the link to the towers generator, the designer explains very well all that.
A "vortex tower" file is available on econology.
There are 3 main patents of vortex towers:
1) the vortex tower of Edgard Nazarre, the pioneering project.
2) The AVE of Louis Michaud.
http://vortexengine.ca/index.shtml
3) The self-secure vortex tower, or just the tower generator of Alain Coustou and Paul Alary.
Projects are being discussed, however, and unfortunately no devices have emerged for the moment.

On the other hand, and especially for the Coustou / Alary project, I insist on the fact that this is not a hypothetical technology!
All the principles used in this device have been known for a long time: greenhouse effect, chimney effect, convection, venturi effect ...
To give an order of ideas, with a delta T of 10C ° per positive temperature between the base and the top of the tower, the velocity of the upward air current would be at the level of the 160 m / s venturi!
With 40C ° it would reach almost 240m / s! (More than 860 km / h).
The cost for 300m tower (optimal height) would be of the order of 150 to 200 million euros.

It remains to convince investors, you only have to see the setbacks of Nevada solar one (concentrated solar power plant) near Las Vegas to realize that even if a device works, it takes a long time to convince and break the "energy dogma".
As such the end of cheap oil should give a boost to its technologies.

Thank you for this info. It is true that it is enticing, but for the moment alas, nothing concrete.

I'm learning right now that a group of researchers has come to turn solar energy into ethanol or diesel! And this using microorganisms from biotechnology!

Fuel for the future: Joule Biotechnologies' genetically engineered microorganisms can turn sunlight into ethanol gold diesel.

If it's true, oil could easily be replaced by this solar-fuel. Which is very bad name, because it will not be without consequences on the environment and therefore the climate.

Apparently this type of project - offering the possibility to not change the current mode of consumption - finds funding him.

The positive side would be that these photosynthetic micro-organisms would use sunlight to effectively convert carbon dioxide directly into fuel! Unbelievable!

[dedeleco]

There is no need for bio technology, because nature has been doing this for 2,8 billion years with cyanobacteria and other organisms that allow us to breathe.
Leave water in the sun with a little salt and green chlorella or cyanobacteria (which settle on their own), you have the starting point of oil, carbon compounds!

Finally the vortex tower creates the right conditions to have a tornado or small hurricane with hot air moist at the base that rises and gives up energy by creating winds of hundreds of km / h!
The higher it will be 300 to 800m, the better it will be !!
A scientific certainty !!

Its biotechnological "solutions" are just nonsense.
There is also research to make hydrogen from seaweed ...
We fall back into the problem of "agro-fuels". The surfaces necessary for the operation of our car park, for example, would be absolutely gigantic, and the ecological impact would be disastrous ...

[Obamot]

Once again you should read the links before saying that nature has been doing this for 2,8 billion years or that it would be disastrous (which is disastrous is the waste generated, by what these technologies potentially allow. these techno in itself ... that's what I meant ...).

No, it's not correct. The originality of their discovery lies in the fact that they have arrived at "intermediate steps".

They said to themselves: "After all, biofuels come from carbon dioxide and water, so why persist in making them from biomass? Why not put in a system that could convert carbon dioxide directly into the fuel they wanted?"

And apparently it works, what they say ...

In this case there is no need to collect on Sen-no-sen agricultural plots.

What you need to know is how much Co2 do these microorganisms burn to produce fuel? And how long does it take. What about the process, could they produce something other than fuel to "assimilate" this carbon? That yes, that would be interesting.

No need to go so high, the optimal size for a vortex tower would be 300m.
The higher the height, the faster the airflow speed.
After a certain height it would be technically complex to recover a transonic flow of air.
For a tower of 300m it would require a turbine of 25m of approximately diameter (ie blades of 11 meters + central core, made of light alloy of titanium type).
