I am Polish ship building engineer. My hobby is transportation but without using turning the axle. On my web site I present my ideas, projects, patents and books.

All projects, patents and ideas presented here, can be realised by Readers in convention “make it yourself”.
Evidently it is possible to buy a patent, license or "know-how", but for today, all detailed description and books are in Polish only. But I offer my help for everybody.
Special offer is “water glider” presented on animation.
