Recycling, I urge you to edit your previous messages to be a consequence, rather than add sequences of a few lines every x minutes.

For me your behavior is similar to what is called FLOOD and will result from tomorrow by the outright deletion of messages without any qualms on my part.

This has nothing to do with the econologist behind the keyboard but it's just a reminder of simple operating rules of forum in order to maintain a correct readability of the words.

Thank you to you to comply and edit / structure your messages.

Finally, we will say that it is oriented information, which maximizes the returns of the right column and minimizes those of the left column.

That said, for the sorrowing spirits (yes, yes, there is some here : Shock: ) and those who swear by the white OU black (there are also some : Cheesy: and sometimes they are the same! : Lol: ), I repeat once again that I have nothing against EVs, I am even very much in favor of them.

On the other hand, I hate that one "stuffs me the slack" (meow?) With pretty graphics and especially that one says to me "it is like that and not otherwise" without other explanations ... (and in refusing to discuss)

Hey no because ... He is the author! (from the article not from the diagram) ... : Cheesy:

From the article and the diagram:)

The% of the left column is very generous;
Explanations here:

http://www.electron-economy.org/article-23222635.html

(...) The conversion efficiency of the total biomass to agrofuel retained here is 90%. This is an ideal yield, if huge progress is made by 2020-2030 (...)
In addition, the efficiency retained for the heat engine is 30%, while it is 20% the good value in ordinary use cycle.

In short, we can easily divide by 4 the overall yield of the liquid biofuel industry, and we then arrive at a factor 400 difference (instead of 100, which is already huge), which is anything but negligible ...

Yes, that's right, beautiful recycling philosophy.

And in the face of a problem there are two possible approaches:

1 - that which consists of seeing (/ seeking) the problem, criticizing negatively (sometimes making fun of it) without providing a solution.

2 - One that consists of lucidly taking into account the problem and looking constructively for solutions.

We can talk aboutsomethingfuel to make a difference.
For aviation and other applications where you can not do otherwise, this industry has a future in my opinion.
But it will remain a really expensive fuel ... which will push for example the abandonment of flights of short distances, and their replacement by the electric TGV for example (much more profitable and ultimately faster for the user: no metro / bus-shuttle / taxi to the airport, less waiting to board etc.).

Air France is seeking to acquire TGV lines at the moment.

A serious environmental impact study of the algofuel sector remains to be done entirely.

these apple trees were raising to the height

that's how cow and apple live together, ...
