Flywheels as energy storage system!

[Reformator]

A flywheel is a mechanical battery (a mechanical means of storing energy - simply a mass rotating about an axis). Flywheels store energy mechanically in the form of kinetic energy. Kinetic energy is energy of motion. The kinetic energy of an object is the energy it possesses because of its motion. As energy is transferred into a flywheel, as it spins, it builds up kinetic energy that can be released when necessary.


This technology deserves attention. It can solve the issue with the free energy devices that give more energy than needed. I mean if a solar panel collects energy all the summer, and there is an excess of power, it can be stored for later use (winter)!

Hello  Reformator!

You're absolutely right, of course. You might want to check out the following company:

Howdy Reformator,

My you are busy.  So many topics in the one day you have been here.  I guess you have a lot to share with the world.  The flywheel energy storage device is not a new topic.  Here's something for you to check out...

Engage your spinning flywheel with a second flywheel that is of equal mass and dimension; and is at rest. You will find that their rotational velocity will be halved.

If you do the math you will find that the total kinetic energy is also half.

If one flywheel has a rim mass of 40 kilograms and a velocity of 2 m/sec, its kinetic energy is 80 joules (1/2*40*2*2). The kinetic energy of both (80kg) moving a 1 m/sec is 40 joules.

So you see flywheels do not store energy they store momentum; Linear Newtonian momentum, no less.

Wouldnt it actually be less because the intial engaugement causes a huge loss do to friction not to mention the process of engauging takes an amount of energy as well.

I think it would be safe to say once fully engauged you have less the half of what you originally started with.
