Im looking for a few motivated individuals to help me build an amazing free energy generator known as a gravity battery. The concept is very simple; picture a grandfather clock which has elevated weights which fall slowly and turn a series of progressively smaller gears, then using those gears to turn an alternator which produces electricity. There is nothing experimental here, its just a matter getting the gearing and weight ratios worked out for the desired power output you want. I was thinking of using recycled gears out of an old car transmission, and maybe even use salvaged car alternators too. Eventually this could be worked out to power a home, but the first prototype I want to do a bit smaller in scale. Perhaps something that could power an RV. The power to weight ratio can be looked at like this, There is 1 horse power generated from 550 foot pounds falling in one second of energy (or 33,000 foot pounds falling over one minute or like a combustion engine 1,980,000 foot pounds over one hours time), 1 horse power is equal to 68.6 gallons of water falling from one foot in one second. This means there is a potential 750 watts in every foot of descent of a mass of that size, double the mass and double the potential. The gearing is based on a few things, first the output desired must be calculated and then the time in which you want that output, then you have to figure out how much mass is required in foot pounds to achieve that specified output and then you determine the height by applying those numbers to how many hours you require energy production. So for every 750 watts it would require the above mentioned 68.6 gallons to fall 1 foot if all things were perfect and there wasnt any resistance (so factor in the resistance coefficient to get a real idea of power output). Now if you wanted 750 watts for 20 hours it would take 20 feet of drop to achieve. Now the full 750 watts is only the potential gained after a mass of 550lb. falls from one foot at free fall speeds. It is the force generated by the mass in motion at a velocity achieved from one foot above the ground that delivers the full one horsepower, so to make a usable mass generator you have to design it so every foot of descent of the mass is delivered to the flywheel as an impact, so the gearing allows the weight to fall one foot and then engages a drive mechanism to spin the flywheel delivering a constant rotation to the generator. Every impact throughout the 20 foot drop delivers one horse power to the flywheel so there is a potential 20 horse power in the 20 feet of height. The trick is harnessing it effectively. Now lets look at the math and figures for a transferable mass system. First we need a pump to transfer the fluid mass from the lower container to the upper one, I used a 12 volt 4 amp 1200 gallon per hour pump. This pump says it has a max efficient height or head of 8 feet, so if the pump uses 48 watts to transfer 1200 gallons to a height of 8 feet, how much potential energy is in 1200 gallons at one foot of drop? there is a potential for 2.18 horsepower or 1635 watts, now multiply that number by the over all height of 8 feet and we get a potential 17.45 horse power or 13,080 watts. Lets look at the differences now between power input and power out put, First if the pumps rating is correct it took 48 watts to transfer the liquid mass to 8 feet above the ground, and if we do the math on the potential now contained in that mass we see that it has a potential of 13,080 watts.That is 272.5 times less power required to move the mass in small quantities than is available in the total sum of the mass in potential. Now lets say the system cycles every one hour, 24 hours a day, that would give us 313,920 watts output with a 1,152 watts input to pump the fluid. Is anyone up for the challenge? Once we get it all worked out and have a working model I would like to make a tutorial for youtube and share it for free with anyone motivated enough to build their own. The advantage of this type of device is that unlike solar and wind power which cant always be counted on, gravity works day and night, rain or shine and with or without wind. It is also less expensive than solar and doesnt require toxic batteries which are expensive and have to be replaced every few years since the power is always being produced on demand. Also, it can be build from salvaged materials. The power system is easily the most expensive part of an earthship. This will reduce that cost significantly and make an Earthship style home that much more achievable for those on a tight budget. Lets change the world!
