I think this is a fascinating project. Perhaps a hydraulic version with an incompressible fluid which also acts as a lubricant within each tube connected to a central hub might improve efficiency? The central hub could be a larger tube with an elastic membrane that deforms inwards as the incompressible fluid is drawn out into each tube. Something like that.
If you sequence each pump individually through the center shaft it could be possible to rotate the weight throughout the night as well.
I remember reading somewhere that with compressed air energy storage lower PSI values were more efficient at storing energy. Since I guess this is sorta like the opposite of compressed energy storage I guess the same math will work here? i.e. half charging the battery might be more efficient or maybe 5% -> 70%. Another thought is that if you seal the top of the vacuum tubes you can compress the air at the top of the plunger too and that should increase the energy density by having compressed air and vacuum storage combined.
Dude i love this video
Goeie video man, zou je water kunnen gebruiken om het rendabeler te maken, sochtends vroeg leeg omhoog tillen op de energie die je opwekt en savonds vullen met water om te laten zakken. dan zouden katrollen en tandwielen het kunnen helpen als gearratio verranderd met dat t zakt en stijgd
Unencumbered by the thought process or reading most of the comments, I'd say that using vacuum limits you to 14.7psi. I don't know if a compressed air system is as efficient, but going to something like 1,100psi would give it much greater energy density. Even if it was better, eventually the cost to scale up might be prohibitive. Great work though. I love people exploring every option. Sometimes you get surprised.
Ik vrees dat een langere tijd de druk vasthouden toch druk vermindering zal veroorzaken. Ook zou ik de buis en de rubber behandelen zodat ze makkelijker glijden (voor een betere efficiency en een betere afsluiting.
For a split second I thought you had build a device that uses changes of atmospheric pressure to generate electricity.
Why vacuum? Why not air pressure and turbine? Much simpler to build and there are tons of compressors available
You could increase the power capacity by stacking the cylinders and idk if you if you have it built in yet but if you put 1 way ratcheting mechanisms onto the motors it will help reduce power loss between cycles so in turn higher efficiency
looks like there was a ton of air (relatively speaking) that was leaking in, u could see the bubbles. I think this has some potential as a larger scale energy storage tho
Wow if you were able to scale this up to house size, the vacuum produced would be amazing. I would be worried if it ever cracked while under vacuum; it would probably create a powerful implosion. 😮
To determine whether it's worth it, an important comparison needs to be made: energy production per space used. We know the eROI is 73%. However, we must determine how much space each method uses to provide the same energy. By this, I mean the space taken by the entire device. For pump hydro, this would include the turbine, the water pump, and the water tower. You mentioned this a bit when you started the video by talking about the size of the weight you would need to supply energy for the house. However, you never calculated how big this system would need to be compared to the gravity battery.
*Move next to a strong river!*
this channel is super underrated!
Hey, Is the problem with the arduino code for your tennisball launcher on cults3d fixed?
This looks promising. I have an idea to increase your 73% efficiency, The vacuum tubes are clearly creating a suction force. Why not use this suction to draw some water up some extra tubes which contains a water turbine, then when the vacuum is released it will force the water back again thus generating electricity in both directions.
I think the fact it works on a small scale means its worth looking into. I would imagine the large scale versions wpild have some new issues. For example, what material would be ideal for the tubes on a large scale? Something that can withstand higher amounts of negative pressure might take a tonne of space
Очень сильно зависит практичности их применения: Закачивать воду в водонапорную башню - имеет смысл! Гравитационная батарея - для лифтов идеальное решение - но куча инженерных проблем - которые делают сабж непрактичным. Атмосферная - это же пнивматика обычная... фигня какая-то. Электрический аккумулятор - его энергию можно эффективно преобразовать в любые из перечисленных типов энергии - а вот попробуй преобразовать выше перечисленные - тут начнуться инженерные сложности, а вот под эллектричество - у нас есть мотор, насос, и т.п.
it is actually done already and its called pumped storage powerplants. One in a town near me lasts for one hour of energy tho... So it still would be better to stop hushing nuclear energy
Try 2 make a 1kwh storage. And keep it diy, because the people need this in the future (1 a 2 years from now). Every power storage solution is needed for home use.
its beatiful mate .. how well you put the idea into a model is so so very commendable!
it's a failure at the conceptual stage. Vacuum chambers constantly get bleed from outside. So the battery is going to lose charge from that. Pressure needed to maintain a seal will introduce so much resistance that the waste heat will make the battery too inefficient to be usable. Go with hydro-electric gravity batteries. Since you want it compact, use mercury instead of water. additional safety measures will be required since water leaks are no issue while mercury leaks are a major issue.
What about just sucking the air out of pressure vessel and use the inflowing air to power a turbine?
Natuurlijk is dit goed. Lithium wordt schaars en en lithium batterijen zijn brandgevaarlijk. En je vergeet bij de efficiency score de baten/kosten verhouding!
All these modern start-ups trying to make gravity batteries are crazy. Water will ALWAYS be the best gravity power storage source.
Is it possible to reverse pulley system while charged to maximise energy generation?
the efficiency is low because of all the friction. maybe use a friction less air seal. and use a some kind of auto gear so its gets easier too pull up, then switch for more force going down.
Dude, you are in desperate need of a dynamometer.
0:16 dont ask me that. i already know the ending.
BUILD BIGGER
Well done! I hope you get to give this another go with more expensive and hardier materials
I liked that. You should definitely look into a few more iterations of this vacuum system. But instead of electric motors to set the load against gravity why not combine the concept of the sand battery which is loaded with waste heat from trash gasification and incorporate that with your vacuum battery (think Boyle's law/ gas law). Your current set up is not optimized, I think your belts are causing losses due to the elasticity of the belts also there maybe energy losses due to temperature changes in the gas in your "vacuum" so yes you should redesign and optimize for a few more iterations of this.
WATER STORES ENERGY MATE
Better than pumped hydro, huh. Maybe you could combine the space it takes into the efficiency calculation as well to know how large of a vacuum chamber would be needed to replace a pond. I wonder how this compares to compressed air. Make another video about this! I must know dammit!
As for using old mineshafts for energy storage with weights mentioned in the start, I really have my doubts about the viability of that from a practical standpoint. I work in the mining industry as a geologist and maintaining an abandoned mine is very expensive and a huge liability. Underground mines are almost always below the water table, so there needs to be constant pumping and maintenance done to prevent flooding. The ventilation would also need to be maintained to prevent explosive gas buildups. Any unsealed areas could leech more toxic materials into the mine water. And mines are naturally unstable, they will collapse eventually.
Guess the energy density of this contraption
The mineshaft example is similar to water resivor batteries. When you have small amounts of energy, you pump water uphill. And then when you need energy, you let the water run downhill over a turbine.
The reason pumped Hydro is so good, is that it requires little maintenance. There isn't a single heavy weight to move, there aren't many moving parts, and the parts that wear out are a small portion of the overall system. Unfortunately there is a large upfront investment. The issue with this system, is that it has many parts that are likely to wear out.
Charge the battery when air pressure of the weather is low, and discharge when the air pressure of the weather is high?
Would be interesting to see how it loses efficency over time as I assume the charge-discharge you presented were performed right one after the another. I have a hunch that those homemade syringes don't hold vacuum well over longer period of time, like a day or some hours even maybe...
73% for a 3d printed prototype is awesome lol
Un permutador metalurgico
1:00 water storage like that already invented
Well, since you excluded from this scheme a bulky, heavy heat accumulator with 100 tons of sand, then this is already a success. And seriously, I like the elegance of this solution, even in spite of the many "extra" mechanical parts of the generator-battery, because they are elements of surprise - they can fail at any moment, which will spoil the operation of the system. But the concept itself works and if it is brought to 80%, then it is already worth doing on a large scale. My guess is that the closer this system is to a free solar or water resource, the less efficient it can be. And, conversely, the further north, where the need for energy is higher, the more efficient this system should be. Well, even 73% will come in handy somewhere, although of course, the more the better.
Echt een super leuk idee! Als ik verstand had van electronica dan had ik ditnook gemaakt!! Ik vind dat je zelf commentaar geeft ook stukken beter dan die robot die je in je andere filmpjes gebruikt hebt! :)) Ik heb geabonneerd
Considering the ideal gas law: PV = nRT I'd love to see you incorporate an efficient thermal aspect to this design to see if you can further improve the efficiency of storage / discharge.
Imagine springs exists... such a wasted time. LOL
you'll be loosing most energy through friction. It would be interesting to see if very light lubrication helps at all.
