Hello Phill M; Here is the updated block diagram showing the solar side with auto circuit between the solar and the system that separates the solar. When the batteries are charged the solar dumps all it's output into the power grid through six(6) grid-tied inverters. I don't rely on the solar that much it's not reliable during cloudy or rainy days or snow cover, plus the trees have grown and shadow the arch of the sun at certain times during the day. I stated in the beginning I used solar and found it was not reliable. Regards Bob

Hi Bob, It would be interesting to know the total power consumption of your house as well as the total grid export/import, also a breakdown as to where the power was being supplied from eg- Total Solar & Total Wind , Other? This would then give everybody a good picture of your systems workings and its efficiency.

This cant happen, its one of the laws of thermodynamics. Every time you convert energy from one form to another you loose, no exceptions. No process is 100% efficient, there will always be some loss. If the meters say you are gaining watts, then there has to be a incorrect measurement made somewhere. Interesting set up Mr Delanco, but I do agree with other forum members, its does seam overly complicated. I wonder if the net output would be higher is you took out a few steps. I agree adding large caps across the batteries can help, especially with wind turbines. Glenn The best time to plant a tree was twenty years ago, the second best time is right now. JAQ |

Hello Glenn; What conversion are you comparing thermodynamics too? There is only one conversion of Ac to Dc and that is the rectifiers after the 1st. Alt-Generator. The rest of the system generates and continuously stores DC building a stronger storage base of usable power. Do you understand Ultra-capacitors of this size? Bob.

Where do some of the questions asked here help in showing how using recycled items to build a mill and pma can be done ? I am trying to show about recycling the items around you into usable energy sources. This was suppose to open up a new light on recycled items and there use's. I built a working wind-mill and pma from recycled parts, This is what I am sharing with others. Not everyone has the resources I have available to me. This was not about me and all the subsystems of my system. It is about recycling. It is about how to use recycled items for use's they were not intended to be used for. Bob.

It is very good to recycle itmes for energy uses, I have since found microwave transformers to remove the coils and bicycles for the gears and chain. Mr. Delanco keep us posted and nice setup you have there. |

Hi Bob, I hear you on the use of recycled parts. That can be fun and informational. I sure hope that ford isn't sucking in too much dirt without it's air cleaner lid and you kids don't have unrideable bikes... 
I believe all the conversion steps are what is being described above by Glenn are; Wind kinetic energy --> rotor kinetic energy rotor kinetic --> generator electrical generator electrical AC --> gen DC Electrical energy --> chemical energy in the cap (I think) Ultracap chemical potential energy --> electrical current electrical current --> chemical potential energy in the batteries chemical potential energy in the batteries --> electrical energy electrical energy to mechanical energy then back to electrical energy in the flywheel and on and on and on. There has to be energy lost in each of these steps. If you put 100 watt-hrs into a batter you don't get 100 watt-hr out. Those are all conversion steps that thermodynamically will never be %100 and will always cost you efficiency/energy. I think we can all agree that there are only 2 things creating energy in your system, the turbine and all that solar. All the other items are conversion items that cost you energy. I think that is why everyone is saying that either an appropriately sized flywheel or battery bank (caps helping for other reasons) would be more efficient. But for use of used parts and recycling, you get an A. Perry Perry |

Question: What is an ultracapacitor? An ultracapacitor, or "super-capacitor", stores energy electrostatically by polarizing an electrolytic solution. Though it is an electrochemical device (also known as an electrochemical double-layer capacitor) there are no chemical reactions involved in its energy storage mechanism. This mechanism is highly reversible, allowing the ultracapacitor to be charged and discharged hundreds of thousands of times. An ultracapacitor can be viewed as two non-reactive porous plates suspended within an electrolyte, with a voltage applied across the plates. The applied potential on the positive plate attracts the negative ions in the electrolyte, while the potential on the negative plate attracts the positive ions. This effectively creates two layers of capacitive storage, one where the charges are separated at the positive plate, and another at the negative plate.

An ultracapacitor is different than a battery, and depending on the application, may be a better solution. Often, a combination of the two is the best approach, combining the excellent power performance of the ultracapacitor with the greater energy storage of a battery. An ultracapacitor can be charged to any voltage within its voltage rating, and can be stored totally discharged. Proper system sizing includes accounting for a capacitor's voltage change as it is charged and discharged. A battery operates within a very narrow voltage range, determined by its chemical reactions, and can be permanently damaged if over-discharged. State of charge of an ultracapacitor is simply a function of voltage. State of charge of a battery involves multiple dynamic calculations. An ultracapacitor stores much more energy than a conventional capacitor of similar size. A battery will store much more energy than the same size ultracapacitor. In applications where power determines the size of the energy storage device, an ultracapacitor may be a better solution. The ultracapacitor is able to deliver frequent pulses of energy without any detrimental effects. Many batteries experience reduced life if exposed to frequent high power pulses. An ultracapacitor can be charged extremely quickly. Many batteries are damaged by fast charging. An ultracapacitor can be cycled hundreds of thousands of times. Batteries are capable of only a few hundred cycles. Is an ultracapacitor better than a battery?

Thanks for that link Bob. For those who do not want to wade through the 5 pages of question/ answer entries, the losses of their super capacitors are quoted at: 1.2% loss of charge per day. So, if its fully charged it would take a bit over 83 days to lose all of it if no recharging occurs. Sounds pretty good to me, pity these things are so expensive in small quantities. If you were to order a million of them  then their price is 1cent per Farad Klaus |

Ultracapacitors from Maxwell are rated at 2.5V each. They can be charged to higher voltages, but it should be noted this would effect the useful life of the product. Maxwell Technologies does not recommend the operation of the ultracapacitors above 2.7V. By applying a low charge into my ultra-cap array I am able to build on the charge to a higher voltage. The charge equalization circuit, balance circuit is a standard design available from several sources, I customized a circuit design to meet my needs. As the cap charges to 2.5 vdc the extra is passed to the next to allow that cap to full charge and so on. By cascading this allows the array to build not only a higher voltage but also increase's in amp's and watt's. Food for thought; Conventional flow from positive to negative is thought, but the actual flow of an electron is from negative to positive. Individual cells are rated to 2.5V each. There is no limit on the number of cells that can be placed in series to attain higher voltages.

Hi Mr Delanco, While any effort to recycle is noble,to have a significant impact it needs to invovle the masses,otherwise it becomes largley academic.Would your system be achievable and economically viable for the average Joe like me?Cheers Rastus see Rastus graduate advise generously |

Everyone has items large and small around them that are no longer being utilized. You and others can build a windmill and pma out of the items available around you and build it better then my system. some basic items are; 1. desk chair base. Trash picked 2. bicycle parts. Trash picked 3. round metal lid. Trashed picked , I could have used trash can lids. 4. copper wire. Trash picked 5. blade hinges old large nails and gate post hinges. 6. blade control rods. Old baby crib rail guides. The items don't have to match what I used. they can be anything that will work for the use's you in-vision them for. There are item's all around you that can be used. Learn to see item's around you and vision there use's and how well they may work for that use. Train your mind to look past the integumentation. Others can achieve they only need to try.

The Alt-Generator was built from recycled items. The output was split to charge different loads. 12 volts, 24 volts, 36 volts. 12v and 24v Charge ultra-caps then into a charge controller then into the storage batteries. Construction of the Alt-Generator Two magnet layers "over-under" for low speed operation. Designed to operate from the cycloturbine wind mill. Magnet wire came from several source's of old transformers ect. Modified a small portable drill press into a coil-winder. Polycarbonate sheet for open coil housing. Ford air breather top for lower magnetic base. Bicycle wheel. Skateboard wheel bearings. Ceiling light flange for bearing holder, drilled out with a step-drill bit. Bicycle wheel & bearing hub was right size for holding skateboard wheel bearings. Teco braces for coil coolers and to support the top magnetic array. Ford air breather top for top magnetic base. Output from one coil at 2 mph = +5 volts. Total output from all coils with no load at 2mph was +70 volts. Output was split to charge different loads. 12 volts, 24 volts, 36 volts. Two magnet layers "over-under". Installing the Alt-Generator to the cycloturbine The Alt-Generator up and running Tip; Build your magnetic's 1st then test one of your coil's at a time.

hi mr Delanco something you wrote earlier in one of your posts fascinates me .... The Motor-Generator-Flywheel ups unit is an integrated component of my system and uses part of the earth's rotation to assist the flywheel's rotational motion this was a plus could you elaborate on this a little ??? what kind of power output for a given wind speed do you get with the vane type vawt ? niall |
