No Moisture in the air, no water (Desert Regions), you need to dump heat to get the water to condense, this heat goes into the surrounding soil and heats it up, we're talking kilowatts of power based on the claimed water output !!!! 2AM here and time for me to shut down for the night. I hope that Dan doesn't get discouraged as he asked his question in a very well written way and he did a good job instigating this discussion. In this case the poster is convinced by the apparent output (Greater than unity gain of input to output ) but does not have the background to know it is not possible, Even your example of the geothermal, if you just stick to energy in vs out rather than money in vs product out, it is still not 100% efficient and certainly not greater than 100%. Isn't there room for thought on that approach? I am quite sure that you have NOT seen any such thing but it may be that some freak circumstances or clever tricks have deceived you. Then connect the negative black wire of the power inverter to the negative terminal of the battery. See here for some more discussion on it: https://www.physicsforums.com/threads/how-to-use-an-electric-motor-to-recharge-a-battery.535694/. DC motors normally have just two leads, one positive and one negative. However, when the 2 105 @ 20 hrs batteries in parallel are used, and then put on charge after use, the batteries typically register 50% charged. your right, I was just was just trying to break down the laws in which John had explained so well. Attach the opposite end of the red wire from the 24 volt DC motor onto the positive terminal of the power source labeled “Pos” or “+.” Use a strip of insulating tape to hold it on the terminal, if the power source doesn’t have screw connectors, or if it does, loosen the screw and insert the wire under screw and tighten it. I am building a quadrocopter with four 6V DC motors and an arduino nano. I enjoyed reading your post on thermal dynamics. Sounds like those mythical 'free energy' ideas. In either case, the battery provides direct current. Mini DC motor. However the energy we loose from the big battery will be much greater than what is gained in the smaller battery. Which is why cars stopped using DC generators around 1964 and started using alternators (which create AC power and then convert it to DC through a bridge rectifier). Since electrical energy can only move one direction at a time we can not use the battery to spin the motor and use the spin of the motor to recharge the battery simultaneously at the same time. Although arguably you couldn't say you were charging the battery because the net flow of current would be out of the battery not into it. He currently holds a Bachelor of Science in electrical engineering from the University of North Carolina at Charlotte and a Master of Business Administration from the University of Phoenix. So how do you get around this. Maybe using those panels just for cross-walk and other special danger areas could be worth it for the safety factor. I agree with. We will always have less after the process than we began with. Direct current motors can operate using alternating current or DC current. are coming from the battery to the motor, and how many amp/volts are needed to continually run the motor? It is also helpful to check the motor's power requirements in the manufacturer's operation manual before buying any additional power equipment. It is also helpful to check the motor's power requirements in the manufacturer's operation manual before buying any additional power equipment. It would probably output that amount of water where I live, if you add the rainfall. motor.jpg image by Aussiebloke from Fotolia.com. I am throwing darts blindly. To connect a DC motor to a circuit simply so that it will spin is very easy. William Kinsey lives in Concord, N.C. When the DC motor is creating high RPM's, this energy would be used to recharge the primary battery, while also powering other components within the device. i have a local self charge power generator. This battery is your primary energy source. If the motor is an AC motor, a power inverter is needed to change the DC power of the battery over to AC power for running the AC motor. Plug the AC motor into the electrical socket on the power inverter. But since then, and with the advancements in the field of electronics its getting closer to that dream of coming true. There are probably hundreds of such discussions on the Internet - for some reason it seems a popular thought. I have found that people who use their imaginations to try to come up with new ideas, even when they do not have an in depth background in the science, are often the source of new and innovative things. Now let's assume that we have a crank on the motor and we can turn that crank very fast. Connect with your peers and get expert answers to your questions. It takes much more energy to get that vehicle moving than you get out of regen braking. If you connect these two leads directly to a battery, the motor will rotate. I might be reading it wrong, but that wind-powered water maker seems to use wind power to push moist warm air down into an underground reservoir which I presume is cooler and causes the water to condense out. element14 is the first online community specifically for engineers. For large scale generators I think they may already perform heat recovery. Let's expand on that. Using the inverter calculator, indicates ~14.35 Amps DC load and then running the sizing calculator suggests that I need battery capacity of 306 AH 20 hrs. The battery should also be able to supply the motor's needed current. Use 9V battery for powering the Arduino. We also loose energy to heat in both directions. Note the motor's start-up current requirement and the continuous current requirement. The Arduino is going to be powered by the USB connection while the DC motor is going to be powered by a battery pack. So I guess the better approach on this, is to determine what amps/volts, etc. In most cases the cost of the harvesting or recovery technology is more than the value of the return. Battery (I used a NiCd 1.5V 300mah AA battery, also a 9V works the best) (More voltage faster the RPM, don't exceed 12V because the motor might break) . Example two: We have a battery spinning a motor and at the same time we have a battery of a lower voltage connected across the circuit. The design should … Just as I posted my last comment, it seems that I had some others come in. The lower the rated voltage of the battery that has to be recharged, the less work the human has to do in order to recharge it. Originally Answered: How can you power a three-phased motor from batteries? Motor provides charge to a second battery. Connect the positive terminal of the battery to the positive terminal of the motor. and the only way I know to make a motor more efficient is to get rid of the friction created from the motor turning and the bearing rubbing on the two surfaces. DC vs AC Current. Heat is also produced in the process and this energy is lost to the environment and is not practically recoverable. The second battery is being used to power lights. I'm working on a similar project. There is no way to use a battery to spin a motor and use the same motor to charge a battery at the same time. There are many motor choices on the market today, from heavy-duty AC motors to tiny DC brushless and stepper motors. Seems to me, that if you generate 120 volts from say an alternator. I too had the dream of making a perpetual motion device too. I am just trying to get a grasp of one, whether the idea will work, and two, what would I need to make it work. If it is, one thing I concern myself with, is that the battery designs of today, mostly only have one connection, which is used to plug into the charger or to plug into the device you wish to operate. This is because they have not yet been taught what is impossible and they are free to go beyond the bounds of this restriction. Disclaimer: The opinions, beliefs, and viewpoints expressed by the various authors and/or forum participants on this website do not necessarily reflect the opinions, beliefs, and viewpoints of Digi-Key Electronics or official policies of Digi-Key Electronics. Connect the positive red wire of the power inverter to the positive terminal of the DC battery. Calculate cost of electricity for three phase electric motor →, Measure a long or short shaft outboard engine→. “Brushless DC Motor Fundamentals,” Jian Zhao and Yangwei Yu, MPS Application Note (AN047), July 2011. so without finding a way to reclaim the heat loss or get rid of the friction, no there is no way at present recharge the battery with the motor as it is. In this example, the device housing these components would be a cooling fan for a motor design I am working on. This does NOT mean "you should know before asking" but "be curious and search to see what is the point". Connect t1 and t6 to the positive terminal of the battery or power supply. All you have to do is connect the amount of DC voltage to the motor which it is rated for. It isn't. He started writing articles in March 2009, which have appeared on Autos.com and CarsDirect.com. I suppose if you had two sets of armature coils you could technically "charge" the battery from one set of coils and discharge the battery from the other set of coils. Here is the example: You have let's say a 16,000mAh 6S Lipo Battery. I was just thinking outside the box. The issue is not just that your car battery has no slotted outlets in which to plug your radio or flood-light. They use this generator to charge cell phones and tablets with a candle. The over the top claims especially are where it falls apart (I didn't read those details). produced is equal to the half of its terminal voltage i.e. What amazes me more is that it wasn't thought of before .... Enrico ....Didn't you know you can find all the answers on the internet...they might not be right, but because they are there they must be. In some cases DC motors can be very efficient (more than 90%) so the motor would at best run for under 10% longer. Its easy to believe that this energy is free because the engine is already running but in reality causes a small amount of drag, and wastes some energy through heat, light and sound. AC current is the same as your home electricity supply, so a DC motor contains a rectifier to change the internal current to DC. It is like pouring water from one container to another using leaky pipes. Here's what I thought. If you proceed to use the Arduino to demonstrate the Carnot cycle it will be a very interesting project but you will have to give Dan some of the credit for the inspiration. I also understand that in small scale this Ideal is useless. If you make a motor spin with a battery the energy comes from the battery and is converted to mechanical energy and heat in the motor. Most students only know how to control DC motors with the L293D. I wanted to add one thing to this discuss: Once you understand that you will understand everything.
