Pierre Langlois: Driving without oil, Book excerpts

Transport and new transport: energy, pollution, engine innovations, concept car, hybrid vehicles, prototypes, pollution control, emission standards, tax. not individual transport modes: transport, organization, carsharing or carpooling. Transport without or with less oil.

40% x 90% x 90% = 32% (instead of 34%)

60% x 90% x 90 = 48,6% (instead of 51%)



which charger has less than 13 to 15% loss? (for high currents compatible with vehicles) I ask the question. references !!! I want 1.
so if at the entry of the battery we have already lost more than 10%, how the efficiency of the grip on the wheel can be 90%

It's beautiful ... but when does it come out?

You saw Dassault's interview about the Cleanova ... Otherwise, it's over there: https://www.econologie.com/cleanova-de-d ... -3962.html

For the wheel motor, Heuliez announces 90%:
http://www.orange-innovation.tv/webtv/m ... et-orange/

In general I retain the efficiency taken at the wheel of 80%, 4 times higher than that of the motor car from the pump to the wheel. I will research the doc on the subject. But Pierre langlois speaks of 90%, I invite you to ask Pierre Langlois the question.

With 80%:

40% * 90% * 80% = 28,8%

60% * 90% * 80% = 43,2%

28,8> 18

43,2> 18

NB - I have a question: what is the performance of the oil well at the gas pump? (taking into account the energy investment in offshore platforms + petroleum + tankers + petrol stations, also taking into account refining operations) - We could also integrate the energy cost of conflicts linked to oil elsewhere. ..

The wheel motor stinks of whores:

It's a great invention, maybe too great ... to sell ...

I am also convinced of this. It is a revolutionary innovation.

Michelin develops wheel motor in China

Lithium Nanophosphate Battery + Motor-Wheel + BetterPlace business model = electric revolution

Even with tires and gearing optimized for performance (rather than absolute efficiency), the Tesla Roadster only consumes about 110 watt-hours (0.40 mega-joules) of electricity from the battery to drive a kilometer, or 2.53 km / MJ. The energy cycle (charging and then discharging) of the lithium-ion batteries in the Tesla Roadster is about 86% efficient. This means that for every 100 mega-joules of electricity used to charge such a battery, only 86 mega-joules of electricity are available from the battery to power the car's motor. Thus, the “electrical-outlet-to-wheel” energy efficiency of the Tesla Roadster is 2.53 km / MJ x 86% = 2.18 km / MJ.

http://www.stanford.edu/group/greendorm ... eading.pdf

Tesla take-up wheel efficiency: 86%

I believe that based on the best technologies (that is to say the one that must be used to build a green economy), we can retain a return on the wheel somewhere between 80 and 90%.

Note that part of the mechanical energy is used to partially recharge the battery during progressive braking.
Taking this internal recycling into account, a 90% return to the wheel seems entirely credible.

NB - I will look for other references on the new lithium batteries in terms of performance.

Thank you for this link Christophe.
This interview is full of lessons:
Serge Dassault did not offer Renault, unlike BP, a good business model.

Serge Dassault offers an electric car with a gasoline generator to increase autonomy: it is not a relevant solution from a business standpoint. C. Ghosn is convinced of this; his formula about the PHEV (Plug in Hybrid EV) is: "You want a woman and you get a fish; yo want a fish and you get a woman".

This type of hybrid (PHEV) costs more to buy than a gasoline car. With BP, autonomy is resolved with the infrastructure;
and the 100% electric car, without the battery, costs the same price, or less than the petrol competitor: it is attractive to the customer.

Conclusion: Renault signed with BP, not with Dassault.
And Renault works with Nissan for the batteries.

Another decisive factor: C. Ghosn knows that EV will be sold in Denmark and in Israel (BP). In France, it is not certain that mentalities are still ready. Just read the reviews on this forum to become aware of it.

It is therefore better to start in countries where mentalities are ready: Israel, Denmark etc. Then, with the proof that it works in these countries, come and conquer the more difficult countries, like France.


Title of the article:
The Cleanova, an economically and technologically viable electric car that Renault does not want to develop.
https://www.econologie.com/cleanova-de-d ... -3962.html

We should add: ...because of its business model, which is less good than that of BP with which Renault has signed.

P. Langlois has just published a small video that I have just put on the site which quickly presents his book:

https://www.econologie.com/rouler-sans-p ... -4160.html

Bonjour à tous

A few words to inform you of a video interview that I gave to Oikos Blog recently and which has just come online earlier than expected. You can find the video on the Oikos Blog site and on YouTube.
