Small report on a tractor doped in the aveyron on the 7h news from France2.
Once again the term pantone has been "forgotten" and obviously it is a discovery of the farmer himself. Nothing is said either on the presence of the plans on the Internet and on the community of experimenters which has formed around the system.
However, we will note two positive points: we are only talking about water vapor (no plasma) and the participants are not anonymous (wanted to recover the system?)
