Generate electricity by gravitational force?

[Kaf]

Occasionally saw this on internet, do anyone think this works?

"Hi. This is about an idea of generating electricity by gravitational force.

Attached please the basic concept of the idea. The idea consists of two major parts.

The first part of the system makes use of electrolysis of water and fuel cell. A fuel cell on the top generate electricity for electrolysis of water. And the electrolysis of water provide hydrogen and oxygen gas for the fuel cell. The energy loss from this part of the system must be minimized. And some energy from the outside is needed to initiate the system.

The second part of the system makes use of the products from part one (water, hydrogen and oxygen gas) to generate electricity. Hydrogen and oxygen gas will flow upward if it is mixed with heavier gas. Water will flow downward due to gravitational force. Turbines are placed in their flowing paths and generate electricity from their motions.

The system relies on gravitational force to work. If we manage to generate sufficient energy from the motions of the products to overcome the energy loss from the electrolysis of water and the fuel cell, the system can generate electricity by gravitational force."

You will never get more energy out than you put in. (If you disagree with this, then you are claiming you have a Perpetual Motion Machine, which we do not discuss here)

The Perpetual Motion Machines would never work because no system can moves continuously without any external force.

But this concept do require an external input force and that's the gravitational force. This system will never work in the space but it might work on the earth. It's just converting gravitational force into energy.

Can't say you weren't warned.

I find this idea intriguing but also have some concerns. While it is possible to generate electricity through the use of gravitational force, it is not a reliable or efficient method. The proposed system relies on multiple energy conversions and losses, which can significantly reduce the overall efficiency of the system. Additionally, the use of electrolysis and fuel cells can be expensive and may not be feasible for widespread use.

Furthermore, the idea of using heavier gas to mix with the hydrogen and oxygen gas for upward flow is not a sustainable solution as it would require constant energy input to maintain. The use of turbines in the downward flow of water also raises concerns about potential disruptions to natural water flow and ecosystems.

In conclusion, while the concept of generating electricity by gravitational force is interesting, it is not currently a viable or practical solution for widespread energy production. More research and development is needed to address the technical and practical limitations of this idea.
