Could this process using gravity generate electricity?

In summary, the conversation discusses the potential use of a pallet attached to a turbine via a cable or wire as a means of generating electricity. The concept involves a heavy weight falling on the pallet and pulling the cable down, which activates the turbine and causes it to rotate. The conversation also mentions potential limitations and comparisons to other methods of generating electricity.

Imagine a pallet (or any other kind of small platform) tied to a cable or wire, which is itself attached to a turbine, all of this elevated a few meters above the ground. Now imagine a heavy ball or weight that falls on the pallet and pushes it down, thus pulling the cable down which activates the turbine and makes it rotate as a result. Assuming a generator, gear-transmission box, etc,... are properly installed, could this process generate electricity, theoretically speaking?

The omission of the energy needed to get the weight back up or anything else that would make this arrangement unproductive is intended, I just want to know if this process could theoretically be a means to rotate a turbine and generate electricity.

Thanks!

yes don't pendulum clocks use weights to cause the clock to run, no turbine but its running. Similarly wind turbines use the wind but you could attach a weight to blade pulling it down can generating electricity for an instant or two.

Great thanks, good analogies!
 

Related to Could this process using gravity generate electricity?

1. How does gravity generate electricity?

Gravity can generate electricity through the process of converting potential energy into kinetic energy. This can be done using various methods such as hydroelectric power plants or tidal power plants.

2. What is the efficiency of using gravity to generate electricity?

The efficiency of generating electricity using gravity depends on the specific method used. For example, hydroelectric power plants have an efficiency of about 90%, while tidal power plants have an efficiency of around 80%. However, these efficiencies can vary depending on factors such as location and technology used.

3. Can gravity be used to generate electricity on a small scale?

Yes, gravity can be used to generate electricity on a small scale. For example, kinetic energy from falling water can be used to power a small turbine and generate electricity. However, the amount of electricity generated may not be significant compared to larger-scale methods.

4. Are there any limitations to using gravity to generate electricity?

There are some limitations to using gravity to generate electricity. For example, it is dependent on natural forces such as water flow or tides, which may not always be available. Additionally, building and maintaining infrastructure for large-scale gravity-based power generation can be costly and may have environmental impacts.

5. Is gravity-based electricity generation sustainable?

Gravity-based electricity generation can be considered sustainable as it uses renewable sources of energy such as water and tides. However, it is important to carefully consider the potential environmental impacts and sustainability of specific methods and locations before implementing them.
