Diplômé de l’école nationale d’ingénieurs de Strasbourg section mécanique, Jean GROSSMANN dit Balendard est.né le 9 août 1936 à Paris dans le 14ème arrondissement.

Son activité professionnelle a été entièrement dévouée à l’hydraulique. Dans un premier temps l’hydraulique eau lorsqu’il étudie un petit excavateur destiné à creusé un canal de dérivation sous la Durance à Mallemort puis lorsqu’il conçoit avec Pierre Thivans (L’inventeur de l’esquimautage en canoë) un générateur de houle de 12 m de long. Dans un deuxième temps l’hydraulique huile dans la transmission de puissance et les asservissements hydrauliques. Avant de quitter la société OILGEAR en 1997 après une vingtaine d’années de bons et loyaux services, il écrit un livre et développe un logiciel d’assistance technique sur les servomécanismes électrohydrauliques


Bien qu’il soit actuellement en retraite une certaine amitié s’est maintenue avec ses anciens collègues OILGEAR.

I opened the first OILGEAR office in the french territory a long time ago with Bert Burch in Germany. When OILGEAR bought the Towler company to get the China market for the forging press, I was promoted as technical manager for the french territory. I went to Milwaukee many times. Bert Burch sent me to USA one time regarding this software on electrohydraulic servo mechanism. Twenty-five programs were available, and I don’t know why, but Frederic Jamet was using always the same program. This program was showing how in industrial hydraulics systems we sometimes lose a lot of energy stupidly in the extrusion job and this without improving the production and most of the time breaking the OILGEAR pumps.  Now the time has passed, and it is once in retirement that I had the idea to make the relation between a building or a house and an oil tank. Theory is the same. From this reasoning and my love for the river and the defense of its ecosystem is born a 600 pages ebook on this subject to be finalized end of february 2018. You can have a look on this book with attached link

Word pass to read to read this ebook can be provided. You just have to contact me by mail.  The french OILGEAR office has presently a high technical knowledge and I had the feeling they could be able to solve the problem of regulation posed by the “Solar Water Economy”. To understand the purpose, I suggest you to reach the page 599 of my book and have a look how we could solve the problem of earth global warming. Unfortunately for you the book is in french and I don’t know if you speak our language
