.....on net ( www.youtube.com ),then type on "search": "Seesaws on Potsdamer Platz,Berlin".
Have a nice time and...inspiration.
All the best! / Alex
.....can be a simple childish game,or even more.
Maybe,as Plato said "science is nothing but perception"...in the beginning.
Perception seems to be a kind of inspiration...
Now,take a look at : www.youtube.com/watch?v=EgHngvugPSA
Emotion on a bigger and bigger seesaw,can turn back on itself and lead on the new thoughts...

Hi Alex, so what are your thoughts about how the seesaw can be used as an energy device of some kind.
My thoughts would be to have equal weights at the same point at each end of seesaw, then use a means to shift or move one of the weights at one particular end to either make the other side heavier or lighter which would either move that side up or down. As this is done, some kind of linear to rotary mechanical transformer at other end can rotate a generator or one could have coils mounted on the side of seesaw with magnets attached to seesaw that would pass coils and generate electricity. This could possibly be very efficient, as I don't think it would take much energy to shift or move a heavy weight at one end of the seesaw.
Was this along the lines of what you were thinking, let me know.
peace love light

Hi Tyson !
If the "whole is simpler than the sum of its parts" ,this time I am thinking about the CoG (center of weight) :if we carry it on,continuously on the same side of the fulcrum ,we have the "toy".
The main problem is:how it runs?
The best way to understand a game,is directly to play it.
A first step is a stable swinging motion , with a stick and two masses (seesaw).
This is a quasi equilibrium state.
The next step is an as long as possible unstable motion (out of equilibrium) :a full up-down fall(0-180*) of CoG.
Nothing new...
Now,we must repeat this fall of CoG on the same side of the fulcrum...that' all !
Here is a lot of methods,if we keep in mind this "pattern",shape to direct thinking.
The short movies ("Seesaw on Potsdamer Plats,Berlin" and students playing seesaw in the classroom),can help the "think it big".
We can make it simple,plain and easy.

.....this time,at Potsdamer Platz,in Berlin ,if you take a short look at:

As you see,it's a bigger seesaw.
If you play a small seesaw,you can have a lot of fun.
If you play a seesaw as that in Potsdamer Platz,you can be sure to have much more fun...
This kind of entertainment,can be a starting point for meditation...
...with the same "effort" (input),on an extended lever,you can have a "bigger up-down trip" (output),between gravitational levels (height,elevation)...
Sometimes the feelings of a simple game can help our thinking.
My vision about a possible gravity motor has the same insight as that of Tyson...a seesaw "prime line"...with a difference:not swinging,but continuously rotating.

...sorry about the wrong address.
So,again you can play an imaginary seesaw on Potsdamer Platz,in Berlin at:

.....in a different,amazingly manner,if you take a look at:
http://www.youtube.com/watch?v=F_5z3VVqoJk&feature=related
Then,think about the topic of this forum.
With a fulcrum,a lever and a single movable mass...you can build,test and enjoy your own (PM) "toy".
All the best! / Alex
Hi Alex,
There is a Japanese Lego designer, Yoshihito Isogawa, who has some inspirational little machines.
Rolling gear, Scale this concept up and replace the person with this on the end of the lever from your last video.

A flying lever. :D

Many more ideas on his site.

....the simplest possible mechanical game with gravity and inertia.
All you need :a fulcrum,a bar/lever and two masses (one fixed,one movable).
To play "lego" is your option,but the most important thing is as you develop this simple game...
All the best! / Alex

Hi !
This movie is interesting.
In my opinion ,we can see at work a repetitive small unbalance of a lever,due to gravity.
As a result (if we move to and fro the support zone) the fulcrum becomes higher and higher.
At a certain moment ,we can tumble so easy the massive block...from the horizontal to the vertical position.
In my opinion, we can't talk about an "old" or "new" technology....simply is a crank operation ,step by step(practical mechanics).
Maybe an old topic (10/2010 ) is on the same line...
All the best! / Alex
.....this time at: http://www.youtube.com/watch?v=2Z-yqVIQ6dk&NR=1
As a minimum concept,we have here a mechanical driver-follower case.
The acrobat ("the driver") maintains the greater torque (and uses the torque difference) on the same side of the fulcrum.
It's a simplified seesaw game,with a single active mass...we can so easy imitate as a self-moving machine ,due to gravity fall and inertia storage.

Alex, it seems like you're trying to inspire creativity, here. So, here goes nothing.
If I were to attempt to build a seesaw energy machine, this is what I'd try.
On the seesaw, a 50 gallon drum at each end. Two pipes running between the drums, each with a one-way valve. One pipe would flow water from barrel A to barrel B, but not the other way. Other pipe would run water the opposite way. Fill one barrel with water.
Put a hydroelectric generator in each pipe to generate electricity from water movement.
Lift the full barrel side of seesaw up, and water should flow into the empty barrel, filling it. Lift other side of seesaw and the process repeats.
Not free energy. Wouldn't even make much energy. So, let's make more off each lift.
Put a small generator beneath each end of seesaw. The lift would not power these generators, but the weight of the barrel, after it fills with water, would and do so before the lift. Now we're making more energy per lift than we were with the hydroelectric generator alone, and without having to put more energy into each lift. Still not overunity.
Next, put a gravity/buoyancy motor inside each barrel. The weights would be hollow and shaped to float in water. When water is filling a barrel, the weight floats to the top, generating electricity. When the water in the full barrel is emptied, the weight falls, generating electricity.
Will all these combined on one seesaw produce overunity? Probably not. However, a seesaw of this type could be human or animal powered in a pinch. (a person could step down on a side of the seesaw to reset the full barrel to the higher position, for instance)
That's the best I could come up with. Even generating energy 3 different ways per lift, I still think it would take more energy to run than you would get out of it. On the other hand, if looked at as a human powered machine, maybe it would produce more electricity than an equivent effort on a stationary bicycle. I don't know.
Also, going with the buoyancy/gravity motor setup, maybe that could work in places where there is an insufficient grade for hydroelectric operation. Fill containers with buoyant weights down the grade, allowing water to raise weights when filling a container, then allowing weight to fall when container empties?
It's late. Bedtime foe me.
