Gravity is a source of energy and that is the input energy to gravity engine.

How is gravity a source of energy? Isn't gravity just an energy field like magnetic-field or electromagnetic-field? I understand that you can extract energy out of changing gravity field or using field potential, but they are just ways to store/transfer energy.

In not jumping on anyone, it's abit of banter m8. If anyone is upset by how much belief I have this will work, don't let It get to you. I be ok. The children are helping me and we all having fun the comments on weather this will work are about 50/50. And that's neutral. Please take a good look at how leverage works with weights on a seesaw and then visualise the seesaw being the spokes in the wheel. And if it don't work I'll start a thread saying it never worked and everyone can say.... I told you so... And I'll be humble and accept. Till then...... It will work.

You have described how it works perfectly, and you seem to be versed in the laws. But the load is right on the tipping point and the leverage gained in turning the wheel from the edge will be more than enough to turn the screw. The screw is smaller in diameter than the wheel and so will turn faster delivering more water than is being used to turn the wheel.

I'll bear that in mind. If I "balance" more gears ontop of the water screw do you think I can achieve a high enough speed to charge a 12v battery with a car alternator? Thanks.
The amount of water lifted per unit time can also be increased by increasing the rotational velocity of the screw. However, there is a practical limit to how fast one can rotate the screw. A handbook on the design and operation of Archimedes screws (Nagel 1968, p. 37) states that, based on field experience, the rotational velocity of a screw in revolutions per minute should be no larger than 50/D2/3, where D is the diameter of the outer cylinder in meters. Thus a screw with an outside diameter of 1 m should have a maximum rotational
velocity of 50 rpm. If the screw is rotated much faster, turbulence and sloshing prevent the buckets from being filled and the screw simply churns the water in the lower reservoir rather than lifting it

So if I can control it at 50rpm, put a larg cog at the end of the shaft on the water scew line it with a small cog and connect that cog to the shaft of a low rmp alternator, depending on the ratios that saft will spin far faster than the screw shaft, right? I need to see what the maximum rpm I can get on the last cog will be. The two cogs to convert the power need to be as big as poss with as small as poss I guess.edit on 22-5-2012 by Wifibrains because: (no reason given)
