The Power Multiplier Device is the best of the two FE generators. It is located (it's description) on the Overunity.com website, in the community section, under the category 'gravity driven devices.
The second generator is the Pinwheel Generator which can be found by just punching in the title and viewing the sites.
The Grow-Live Tower is simply a cylindrical structure, having a center support pillar, with outside support pillars around it's circumference. Suspension cables connect the inside pillar with each outside pillar to support the floor levels.
The lower 40 levels are where the people live, the upper 100 levels are greenhouse levels. The FE generators provide the energy for the live levels, as well as for the grow levels with their grow-bulbs and heating. Sunlight is reflected into the structure, the outside is all glass.
With each level being 3 acres, each with up to three growing seasons, this allows for 900 acres worth of food for the 5,000 inhabitants. The whole structure requires less than 4 acres of land and will greatly reduce the sprawl effect of big cities.
Water conservation, filtered air to reduce insect-spread disease, clean food and water, are some of the positive effects of theses towers. Electric cars recharge on the ground floor for free.
If one complete tower could be built to show the world, many might follow.
