GRAVITY BATTERY

A gravity battery is a type of electricity storage device that stores gravitational energy, the energy stored in an object resulting from a change in height due to gravity, also called potential energy. A gravity battery works by using excess energy (usually from sustainable sources) to raise a mass to generate gravitational potential energy, which is then lowered to convert potential energy into electricity through an electric generator. One form of a gravity battery is one that lowers a mass, such as a block of concrete, to generate electricity. - From Wikipedia, the free encyclopedia.

I have built several small models using parts from Erector Sets. They all work as expected. Taking the things learned from the smaller versions and applying them to the larger models has proven that the whole concept of a Lifter is not only possible but practical.

A Lifter is used to store it's Carriage contents to a Gravity Bank - Carousel-Gravity Bank

Keep in mind that all of the above are "Proof of Concept" only. The output from a Lifter depends on the Carriage payload, height of the Lifter and drop time. This output has to be matched to the energy usage of any machinery or electrical devices attached. Most of the demonstrations shown have a Carriage with a 400-570 lb. payload. Lifters this size, with a properly matched energy extraction system, would be ideal for home lighting and small device charging. This size is easily built and by daisy chaining similar Lifters, one can match power and usage time to ones needs. Four fifteen foot Lifters, with 500 lbs. in each Carriage, would be equivalent to one sixty foot Lifter with 2000 lbs. in its Carriage. The nice thing about a Lifter is its ability to scale up easily without experiencing a loss of efficiency due to friction. Lifters with Carriages holding 1000 or 40000 lbs can be configured and operated with little more force than that required for one carrying 500 lbs.

Also note that there are two types of tilting methods used to tilt the Carriage. One is a pushing or pulling action from the side of the Carriage and one is a see-saw approach. Each has its own advantage and can be applied to nearly any Lifter design. Early models developed used only the pushing method. This method takes into account the MA provided by the Height/Width ration of the Carriage and has a very great effect on the total starting MA of the Lifter. Using the see-saw method to tilt a more flattened Carriage gives a similar MA (Mechanical Advantage). See the Section A Little Math for a description of this action.
