    I’ve always thought weight has a use as in England we don’t use all what we make (energy) if when making to much we use it to lift weight up and when needed let them go so they make power , I don’t see why we’re not doing it again we used too back in the day it’s like we Brits have gone backwards,
    In the last 1800’s early 1900s when bridges needed lifting it was steam power but when the bridges weren’t being lifted or lowered the a weight would be lifted to help with it 💪🏻

    Do you think this would produce more energy if it were in the shape of an actual wheel? I'm thinking that there would be additional leverage created from the center axis point which would produce more torque. It's just a thought. Any relevant comments are welcome to enhance the knowledge of the CZcams community. Pretty cool working concept!

    • @bclifters
      @bclifters  Před rokem

      The way you extract the energy from the raised weight is really up to builder. In this case a larger wheel would require more building material and the wheel would be large unless you let the water fall into the buckets from the storage height. The energy stored can be released quickly or slowly. The torque would be dependent on the amount of water in the buckets, the number of buckets and how fast you want to use it. Big wheel, small buckets, lots of buckets or small wheel, large buckets, less buckets. As long as the torque is enough to turn the generator you will be halfway there. Thanks for giving it some thought and watching.

    • @bclifters

    Silly thought... Set up as a triangle, vertical side is your up side, and you have the other two sides, which are the same length as the vertical side, pulling down, does that now give you a positive energy on the down side, and a negative energy on the up side? If you have 10 buckets going up, and you have 10 buckets on each leg of the triangle, would that give one a means of making the unit perpetual?

    It’s an interesting idea but it is just so complicated. There are so many points of failure and it requires a fair bit of infrastructure. At the vary least you need a high platform for the water. This could be a tall order for people living on grassland or a desert. Additionally in deserts water may be a precious resource.
    Maybe if this could work with dirt gravel or sand than it might be more accessible?

      Zekiah2, this video doesn't show how the Lifter was used to tilt up the containers of water. Visit my channel to see other videos or visit the website. The simplest Lifter design is a Hydro Lifter using a Pelton wheel. The use of a flowing material such as fine dirt, sand or water, in the carriage of a Lifter, makes it easy to siphon off the stored energy without the need of large front end gear or pulley systems. Lifters are ideal for flat off the grid use, just about any where you can stand up a vertical support.

    • @bclifters
      @bclifters  Před 4 lety

      The Gravity Light uses around 20 to 25 pounds to operate for 20 minutes at eight feet. In this example I was able to get 50-60 minutes for every 10 gallons ( approx. 83 pounds) of water collected by the water wheel. The up front gearing is small compared to the rpm provided by the internal gears and generator of the Gravity Light. See my website for additional info.

    Very nice work. How much power is needed to lift the water up and how much power the system generates?

    • @bclifters
      @bclifters  Před 3 lety

      You must put more work in than you get out. The method used by the lifter, tilting the carriage, is fairly efficient. Sixty gallons of water weighs around 500 pounds. This Lifter has an extended tilt arm and a small distance between the two fulcrum positions that the carriage tilts on. I believe it required about 40 to 50 pounds for each tilt. Five hundred pounds at eight feet lowered over a period of one hour would give an output of about 1.5 watts. Extending the drop time will reduce the output or decreasing the drop time will increase the output. Visit my web site for more info and examples. www.bclifters.com/

    • @bclifters
      @bclifters  Před 5 lety

      You have to lower the carriage of the Lifter and refill it with the water that has been collected. This is an efficiency loss when using flowing material in the Lifter carriage. You must either refill from ground level or collect at a higher level and allow the collected material to flow back into the lowered carriage. However, the taller the vertical support, the smaller the efficiency loss, because the physical height/size of the carriage becomes a smaller percentage of the overall height of the vertical support. Look at my web site for other examples and a discussion of Hydro Lifters as well as other types of Lifters.

    • @bill-wr6tb
      @bill-wr6tb Před rokem

      The bricks are a counter weight when lowering the carriage. The carriage is around a hundred pounds and the counter weight offsets the wasted energy tilting up the water filled carriage. Plus when lowering the carriage it makes it easy to lower. Carriage weight minus counterweight leaves around twenty to thirty pounds to control when it is lowered. If the carriage and contents are to be dropped, as in many of my non hydro examples, a counter weight isn't needed. Pumps have a height that they pump efficiently. The amount of energy put into pumping the water back and for to the tilting action is a little over the energy needed to lift it. Unfortunately, it is not over unity ha! Check out the videos on my CZcams channel or website to get a better understanding of how the Lifter works.. This video starts with the carriage and contents already up the vertical support.

      you can't have a net gain system, it doesn't exist stop trying already. accept reality and deal with it.
      claiming and proving are two entirely different things. no one has ever proven that any free energy generated is actually free, there is in almost all cases either a hidden wire, a tesla coil nearby or a battery tucked away somewhere. if something is too good to be true, in most cases it's because it is TOO GOOD TO BE TRUE and is thus not true.
      the only thing this system from the video does is store power and uses it over a pretty long duration. that energy is the mass of the water falling down due to gravity pulling the water down. the energy required to push it back up is equal the energy it produced on the way down. however nothing is perfect and so you have to tack on inefficiency not just for pushing it up but also when it's falling down and being converted into electrical energy. the potential energy of this system is VERY high however the actual energy (applies to most systems) you gain from it is quite low.
      at best you could have a pulley crank and pull it up by hand, which wouldn't take you very much time and if you built it so that it uses mechanical advantage you could lift it up without breaking a sweat. however again the energy required to lift it would remain the same, the only thing mechanical advantage gives you is that you can do the same amount of work over a MUCH larger time frame which reduces the energy per second you need to move/do work on something. that is, it makes the work easier, it doesn't reduce the amount of work you have to do.

      "You know some people Tinker around with stuff like this as a hobby do it just for fun."
      you know some people spent their entire fucking lives working on equations and procedures just to come to the same conclusion that nothing is free, nothing can be created nor destroyed. free energy isn't a thing, it's pretty foolish to think that it does because then clearly you don't understand physics. if you don't understand that and you think you know better then all of the scientists that spent their entire lives working on these things then you are actually insane.
      there are bounds of reason, and then there is completely off the rails. free energy is off the rails.

    Good idea sir, how many max watt can produce?

    • @bill-wr6tb
      @bill-wr6tb Před 2 lety +1

      The containers hold around 30 gallons each. That would be about 480 pounds total (8 pounds per gallon). This would be almost 4000 ft-lbs at 8 feet. This converts as 1 ft-lb = 0.00037661609675872 Wh. So if the potential energy was drained off in one hour it would be 1.5 watt hours. The output is enough to provide voltage and current for several small LED lamps. Increase the height and/or the size of the filled containers and you will increase the potential energy available. Increasing or decreasing the flow rate of the extracted water will like wise change the amount of voltage and current coming from the generator. Once you determine the amount of output and time of use, you calculate the foot pounds required. From this output value the weight and height of the potential energy needed can be determined to produce it. So the calculated value is the ideal amount needed, but the generator produces back EMF when attached to a load and the loaded and unloaded torque needed to turn it has to be taken into account as well as the over all efficiency of the extraction process.

      Using water as the material in the lifter came after I ran out of ideas using blocks and gears and pulleys and etc. I'm still using solid materials, but water does have some advantages. It is really easy to pull the needed energy from what's stored and you don't have to use a heavy gear or pulley system up front for torque reduction. Check out some of my other videos at my website for a really early history of development. In the end 5 to 6 hundred pounds of something is stored 'x' feet high and it is up to the user as to how to extract the stored energy.

      500-6oo pounds raised 8 to 10 feet is enough to provide for several 3 volt LEDs for possibly 5 to 6 hours. If you want more output for a shorter time then you can drop the carriage faster and provide more torque or rpm to your generator. A larger generator will require more energy to operate and you have to match your desired output to the height of your lifter and the weight in the carriage. Those two variables have to equal the generators input requirements and the length of time you want to operate it. Look at my website or channel for more proof-of-concept examples using solid material in the carriage.

      In most of the videos I've made I use a solid material in the carriage of the Lifter. I decided to try something different like water. It has several advantages but one disadvantage is that once you empty the carriage of it's water you have to replace it. The water collected at the bottom of the water wheel has to be moved back into the empty carriage when it is lowered back down to the bottom. Once the carriage has been refilled then the carriage would be tilted back up the vertical support. This would be the recharge cycle of the gravity battery, making the potential energy ready to use. In the place of water one could use a loose material like sand. It would be much like an hour glass. Using a flowing material makes it easy to release the stored energy in a measured amount without multiple reducing gears, pulleys, etc.

      If you have flowing water, to extract energy from, then that opens up a whole lot of different storage opportunities. Ram pumps aren't very efficient, but they will raise water to a height that would be useful for energy storage.
      I have considered not using solar panels and just rely on the heat from the sun, as you mentioned. Moving a thermally expansive liquid from a heated container up to a cooled container and then reversing the shading to the previously heated container would perform the work needed to tilt the carriage up the vertical support.
      A good example of this type of machine is a "Minto Wheel". Everyone has seen the duck that puts his beak in a glass of water over and over. Temp differential is the big gotcha.

      Kinda cool to bad u couldn’t have this setup then have the overflow fill the buckets on your invention to get more energy out of the water then if it were realistically possible to hook up that ram pump and it works pump the water back to the top and start the process over again or even power another gravity generator
      This stuff really interests me but I know true perpetual motion is impossible but near is until the flywheel looses energy or the battery slowly runs out of stored power until the motion is unable to power it anymore it’s still fun to see what people come up with
      Your invention I think is smart to bad it couldn’t be done in large scale to power cities maybe not even using water but sand or weights but it would still need a person manning it to refill the top reservoir but it could be a source of clean energy even if water ran to low to run turbines

      I agree, these pumps are really unique. Watching them work, looks like magic. I thought there might be some way to use them in a Lifter, and you could, but if you have a flowing body of water then you have a ready made source of energy and there are several methods of utilizing it. Take a look at these and try to understand why they don’t work. Once you start seeing the flaws in these you will be able to apply the same logic to your own and other energy conversion methods that claim to be near or over unity. Enjoy, if you solve the puzzle, you will be the most famous person ever!

    pointless. A solar pane, battery and a LED light would be cheaper.
