Title: Gravity generator Inventor: She, Xiao-dong (Ottawa, CA)

United States Patent Application 20070017412

Abstract: Gravity generator is no pollution and use the rail gravity energy to start the gravity train wheels generator or the gravity disequilibrium wheel generator etc. to generate electricity or to transport etc. on the gravity rail or on the gravity highway. The rail gravity energy is the gravity rail or the gravity highway which can repeatedly and continually and foreverly producing and supplying the infinite rail gravity motive energy to the gravity train or gravity car or various gravity generators etc. to make them speed advance forever on the gravity rail or on the gravity highway. The gravity rail or the gravity highway which is many of the high low slopes rail or the high low slopes highway be arcly smoothly linked then become the high low slopes wave continual and extended gravity rail or gravity highway which can producing and supplying the infinite rail gravity energy always.

Title: Gravity wheel Inventors: Cameron, Melinda Marie (Nampa, ID, US), Bartholdson, Scott David (Port Orange, FL, US)

United States Patent Application 20090282829

Abstract: The Gravity Wheel is a system/cycle of weights that either accept or deny the force of gravity relevant to their position on the wheel itself. The forward motion of the wheel simultaneously is produced by the gravity while it dictates the constant production of energy due to the nature of the motion utilizing the concept of a shifting fulcrum.

Title: Gravity device Inventor: Petkovic, Tony (Vancouver, CA)

United States Patent Application 20060154557

Abstract: The frame structure contains a main shaft, which turns a rotor hence turning four main bearings by using the force of gravity. On the lower section of the frame there is a ball limiting guide which is located on the right side of the main shaft. The distance is far enough away so that steel balls can rotate freely. When the steel ball positions are located on the longest positions of the arms, away from steel ball positions on the shortest positions of the arms gravity forces steel ball positions towards Body Dead Centre. At this time a circular motion is created around the main shaft thus increasing power from gravity.

Title: Gravity motor Inventor: Hurford, John J. (4716 Canterbury St., Westlake Village, CA, 91362)

United States Patent 6237342

Abstract: A gravity motor which is formed of at least one motor unit which has at least one motor member fixed to an output shaft. The output shaft is rotationally mounted on a housing. The housing includes a guide surface. The motor member is low frictionally longitudinally movable relative to an output shaft. Each end of the motor member includes a weighted follower which is low frictionally movable relative to a guide surface. The rotation of the motor unit will cause one weighted follower to be moved toward the output shaft by the guide surface with the opposite weighted follower of the motor member being moved away from the output shaft. The result is gravity produces an overall clockwise torque on the motor member which causes rotation of the output shaft.

Title: Energy generating device Inventor: Rivera-cruz, Luis (H & S Co. 9th M.T. Bn. 3rd FSSG. FMF PAC c/o FPO 96602)

United States Patent 4195486

Abstract: An elongated arm, pivotally mounted at the center to a support structure includes a large, bulbous reservoir attached at either end thereof. The arm is hollow and a passageway therethrough joins the two reservoirs. A volatile fluid which vaporizes at a relatively low temperature (125° F. or less) is placed within the reservoir/passageway to provide the activating fluid for the device. A first insulated chamber including a heat exchange means with source of heat input in the walls thereof encapsulates each reservoir when the reservoir is pivoted to its lowermost point, causing the volatile liquid to vaporize and flow to the other end where it condenses and causes that end to lower. To hasten condensation of the fluid, a second, cooling insulated chamber encloses the reservoir when it is in its uppermost position. This second chamber includes a cooling substance in the walls thereof which rapidly cools the volatile fluid to its condensed state whereby the fluid forces the reservoir downwardly to the lowermost heat input position. An electrical generator or other energy converter is associated with and operated responsively to movement of the arm.

Do not discuss patents here, please 

So, what do you expect ?   is this  Announcement   ?

Hello Marsing,

I am expecting clear list (Index) of Patents granted to Gravity Powered Devices in one place.
Google, Frepatentsonline and others have patents without this particular label (except Primary classes in several groups)
It is useful and fun to collect it

If you know one, put it on the list... 

My staff will be free (in case that I have something patent-able in area of gravity powered devices)
