Gravity Generators

[structure59]

Hi,
Any one who has information about gravity operated electric generators ?
Is it commercially viable method ?

 

[ScottyUK]

If you class hydroelectric as being 'gravity operated' then I guess the answer is yes, it is viable and there is a lot of information out there. Otherwise... what is a 'gravity operated generator'?

 

[waross]

Although this is a very promising concept, commercial development seems to be stalled pending advancements in the efficiency of the Flux capacitor. Development of the Flux Capacitor has been stalled since the departure of Dr. Emmett Brown from the present time.

A hybrid car going down a hill in regeneration mode is a "gravity generator", I suppose.

The trouble with going downhill is the corresponding uphill.

The only generators that use gravity in real life are hydroelectric ones at the bottoms of dams

Of course I can. I can do anything. I can do absolutely anything. I'm an expert!

 

[Skogsgurra]

Isn't Dr. Brown working secrectly on one such generator?

We will surely learn about it when we time-synchonize him any time soon.

I have seen articles on the concept of using weight based generation systems as a means of energy storage, wherein the weight is lifted during times of excess and released during peak demands. But if I recall, none of them ended up being cost competitive to other means of off-peak energy storage, such as pumped-hydro storage (which as others have pointed out is in fact gravity based) or now, compressed air enery storage (CAES) systems. CAES is only now showing its viability, I have a client doing that right now in small (relative to utility scale) "plant peaker" units in the <1MW range for production facilities that need to avoid peak demand penalties or have reliable backup power. It's pretty interesting.

But in no way can there be a pure "gravity generator" that is not associated with storage of energy produced elsewhere, because gravity always sucks and until that is overcome, it always means more energy input than output. Then if someone were to solve the "gravity always sucks" concept, our overall need for energy in transportation would be so diminished that simple solar systems could give us everything we need.

the final frontier. gravity from another dimension. will solve all our generating needs soon, just add in some magnets.

Thanks to all those who responded.
based on some knowledge read somewhere I have the following concept:
3 arms made out of rods at 120 degree with each other in a vertical plane(in wind mill they have the blades).
These arms shall be fitted with 3 heavy balls at their ends (calculations needs to be done to derive their weight).
Once put in rotation it starts rotating at its own. (Of course there will be a retardation in motion due to
i) system inertia
ii) frictional loss and
iii) air resistance)
There is a small motor coupled to the shaft of this GRAVITY GENERATOR which is given pulse after each rotation(derived from the generated power). This input power is just sufficient to overcome the 3 types losses mentioned above. The NETT power available is the usable power.

I am not much sure how to go about all these calculations and find out whether it is commercially viable proposition.
As regards the cost of manufacturing and cost of installation I can do it accurately.
Since this system does not require WIND it can be installed INDOORS also.
And if we make a chamber with Vacuum then the AIR RESISTANCE LOSS will become almost zero leading to increased efficiency.

Let us interact and deliberate on this.

Will you be testing more than ONE UNIT? Or, as it is called, overunity?

No. This no joking matter.

I really hope that you do not expect us to take this seriously.

And I also hope that this thread, which is entertining - but nothing else, will stay for a few more hours.

Before this valuable thread gets deleted. There is one interesting question that is Worth deliberating:

You say that " if we make a chamber with Vacuum then the AIR RESISTANCE LOSS will become almost zero leading to increased efficiency". How is efficiency calculated? The usual formula is eta = output/input. Does it hold also for your gravity generator?

If the output from such a contraption is, say, 1000 W - what is the input? Please state required input in air and required input in vacuum.

The air offers resistance to the moving part and hence if we put in a vacuum chamber there wont be any air and no air resistance and so less loss of power and so increase in ever all efficiency of the "gravity generator".
The output power is the one we get at the shaft of the generator.
The input power will be the "gravitational force" acting on the balls (converted in to rotating motion).
This "Input power" we are getting FREE and is totally environment friendly.
What we face as a resistance is the
i) system inertia
ii) frictional loss at the bearing
and
iii) air resistance offered to the rotating mechanism.

So if we operate the device in VACUUM CHAMBER then we save some power as there will not be any air to offer resistance !

 

[Skogsgurra]

Yes I heard you first time.

My question was: What is the efficiency? You said that it would improve in vacuum. But what is the number? In air and in vacuum?

The interesting part of the calculation is what to put in the denominator...

Energy can neither be created nor destroyed. Brush up on your laws of thermodynamics.

For every downhill, there is an equal and opposite uphill ...

 

[waross]

I am sure that any attempt to produce or patent this concept will result in instant and vigorous legal action from one or more of the major oil companies and or the electrical utilities, depending on the application. The patent and rights to this and actually to any device to produce free power are held by the oil interests and the power utilities.
Some other suppressed inventions: The wagon which had much larger wheels on the back then on the front. It ran quite well with no input power as it was always running downhill. A car with a generator driven by the front wheels which supplied power to a motor which drove the rear wheels. A reverse application of this principle was implemented in the old Penny Farthing bicycles. We have all seen the pictures of these early transportation vehicles. A bicycle with a very large front wheel and a very small back wheel. These never had nor needed brakes. As they were always going up-hill, they would stop quickly as soon as the rider stopped pedaling. The down side was that they were extremely difficult to pedal as they were continually going uphill.
A true story: Years ago a friend of mine asked for advice on an investment. He wanted to share his good fortune and let me invest with him in an exciting new invention:
A flywheel had rare earth magnets mounted around the perimeter. This was surrounded by stationery coils. Properly timed current pulses in selected coils would cause the flywheel to rotate. Properly timed pulses would connect other coils to a load and extract power.
I warned my friend about the possible legal repercussions and he backed away from investing.
The developer found other financing. The first useful purpose of his device was to provide heat energy for his home with resistors. He was able to cook, heat water and heat his entire home with the output of his device.
He had the natural gas connection to his home disconnected and enjoyed his device for a few weeks. Then one day there was a knock on the door. He answered the door to be met with sheriffs, lawyers and technicians. His device was disconnected and confiscated. Then the legal nightmare started. The powers that be wanted to send a message to anyone with similar dreams.
As long as you are in the experimentation stage there will be no action. Very soon after you start to replace any energy for useful work that displaces the purchase of either petroleum, electric or natural gas energy, you may trigger an enforcement event.
Tread carefully.

No need for legal action, there is just simply energy conservation action. No perpetual motion machines have yet to be demonstrated to work.

I suggest that the OP review his high school physics texts on POTENTIAL ENERGY, WORK, and KINETIC ENERGY. There is no free lunch.

Hear! Hear!

Heed all Bill's advices! He has been through it all. He has all the experience that the OP lacks.

And, dear structure59 - don't let anyone know your whereabouts. I am sure that the authorities have already set their powerful Machinery in motion. Activate all yourshields. You have the energy to do that - and it is FREE!

Let's say you have full vacuum, zero friction bearing, and a very large amount of inertia. Ideal case, it will run forever if you don't extract any power.

How do you expect to extract more power than you put in, and still keep it going? Who thinks this stuff up, perpetual motion should be the cut-off point for any semi-rational discussion. Free energy is one big step too far.

 

[btrueblood]

And here I opened this post expecting to see somebody doing research on gravity (or anti-gravity) generation.

Do realize that an effective demonstration of anti-gravity can be done by gluing a piece of toast (buttered side up) onto the back of a common household cat, and then dropping the assembly.

Physikal explanation: cats always land on their feet, but Murphy's law requires the toast to land buttered-side down. In the perfectly performed experiment, the cat/toast combination will rotate at increasing speed, hovering just above the floor, as the two physical laws compete for dominance (kind of like election time). In the imperfectly performed experiment, the dropper is rushed to the emergency room to repair claw lacerations and to have a piece of toast removed from his/her nether regions.
