TASK
Complete
  ·  Re-open Task
|  $5.00

I would like to sponsor $5 for for research to be done for this project. What we’re looking for:

  • Detailed list of ways that gravitational energy can be harvested
  • Information on the efficiency of each of these systems

DETAILED LIST OF WAYS THAT GRAVITATIONAL ENERGY CAN BE HARVESTED AND EFFICIENCY
OF THESE SYSTEM

Yes. The earth’s gravitational pull can definitely be harnessed to get energy. But then you’d have to go against the gravity in the 1st place to build the potential energy which beats the purpose anyway.
It is mathematically impossible to produce power from something that just sits still on the ground, no matter how hard gravity pulls. But if gravity causes motion, we can extract power from that, because the mathematical definition of work is force times distance

HYDROELECTRIC
Hydroelectric dams extract power from gravity via falling water. The weight of water above the turbine exerts pressure, and the pressurized water exerts force on turbine blades, there by spinning a generator. (Pressureflow is mathematically equivalent to forcedistance.) But the water in the dam has to be replenished by the river and rain, or you’ll stop generating power rather quickly. Any effective power-generation system requires a regeneration stage to close the loop and allow continuous production.
In fact, 16% of the world’s power comes from hydroelectricity

GRAVITY LIGHT
London based designers, Martin Riddiford and Jim Reeves, have spent around four years working on an inexpensive and safe alternative that will be of great benefit to many people across the globe - a gravity-powered LED light.
The gravity light consists of an LED bulb fixed to an adjustable lamp that can be hooked up on a wall or hung from a ceiling. It also comprises a pulley mechanism and a ballast bag hanging from the lamp. The ballast bag is filled with up to 9 kg of rock, sand or soil. The gravity light works on the principle similar to that of pendulum clocks that are operated with the help of weights. The potential energy is represented by the ballast material. When the ballast bag is suspended, the potential energy in the ballast is converted by gravity with a slow descent of the bag. The converted energy then generates light.

The gravity light can be operated for 30 mins continuously before the ballast bag needs to be refilled. The strength of the light can be adjusted from strong lighting to long-lasting low-level lighting. The two terminals present at the front of the gravity light can be used as a generator.

SPRING FORCE GRAVITATIONAL ENERGY

In this experiment the small will use spring force acts tangentially (not radially) to the large wheel causing its continuous rotation. Using a small weight and the same small wheel, acting vertically on the big wheel in tangential direction, we will observe the direct conversion of gravitational force into rotational motion. In this experiment, the weight will not change their position in height as well as a spring in the above experiment does not change its state, that is, it remains compressed. This experiment shows the way of direct conversion of the gravitational force in mechanical rotary motion, which means the work and energy.

TIDAL ENERGY.
The best way to harvest energy from gravity is tidal energy.
Tides are created by moon gravity
Tidal energy is produced through the use of tidal energy generators. These large underwater turbines are placed in areas with high tidal movements, and are designed to capture the kinetic motion of the ebbing and surging of ocean tides in order to produce electricity.
