change in gas on the opposite side of the vacume?

how do these compare to air pump + pressurized cylinders

Making a potentially revolutionary invention : 😁 The poison in your drink :

Cool build and concept! I wonder what would happen with the efficiency if you lubricate the pistons?

I would say use as high a ratio block and tackle you can manage, so that it takes a full 12 hours to fully charge and a full 12 hours to fully discharge.

you can just pump air into rubes with compressor and air driven AC motor=\ dude, you are trying to make new bicycle

you miss lab vac lubricant

Within the design criteria there is significant mechanical elements which will be put under significant stress, strain and wear. Maintainance/ replacement will be a considerable issue.

Please remember that with such stored vacuum energy comes the potential for implosion of the vacuum chambers. Very large amounts of energy could be released on implosion. Also, on a grander scale there is the heating and cooling effects intrinsic in pressure changes in gasses. This adds to inefficiency.

just do not put your penis in it!

you can literally do the same thing with a old clock with a pendulum and weights... its just converting kinetic potential energy into mechanical energy and then instead of turning hands it turns magnets around a coil to turn it into electric energy if you do right with your gear ratios you can charge a battery all day. and you just use gravity instead of vacuum tubes.

Great video! Nice build, but this has no potential whatsoever. The amount of energy you can store in such a system per volume (energy density) is minuscule. Pressure is joule per meter cubed (J/m^3) so at atmospheric pressure, you are storing 101 000 joules per meter cubed. Compare that to gasoline that is storing 35 000 000 000 joules per meter cubed. And that does not account for losses. For proper energy storage, we need something that is at worst 10% of gasoline, especially for automotive applications.

Use springs in the base to push the plungers up!

Great video! I can only imagine how much time you had to put into it, very impressive!. Would be interesting to leave it charged for different periods of time and measure how charge capacity is lost over time due to air leaking into the vacuums.

Das ist eine Technik, die nur für maximal wenige Minuten ausreichend Energie liefern kann, um z.b: ein Notstromaggregat anlaufen zu lassen.

this was really enjoyable to watch definitely subbing

Higher infill next time and thinner layers on your print. 60-70% infill.

If this was in a sealed pressurized container the pressure differential would be higher allowing you to store more energy, It wouldn't change the energy efficiency but you could make it smaller.

I saw a system once that used the buoyancy of water to lift a tank, attached to a generator with cables. When it gets to the top on one side, the tank on the other side is filled with air. It like an air/water see saw. I can't find the diagram I saved, but it was a cool idea. I think its called the Willet Buoyancy system.

for any commercial use it would just be better to have a canister that you pressurize and then turn a turbine

You can also put a permanent magnet within the bottom of that metal cylinder and put copper windings around the tube so it induces a current just from the magnet traveling along it's path. This current should then be stored in a small bank of capacitors, and used as the storage of power to be trickled into a denser power bank.

To gain extra charging voltage, couldn't you add two more motors with one way clutches on them, so when the 2 motors are operating to pull the pistons up, the clutch on the other two motors are free spinning, so no extra load is put on the system, and no extra current is being used to run the two extra motors, but when the pistons are pulling back down, the one way clutch will engage on both motors now having 4 motors acting as generators, supplying extra voltage back to the batteries, because by using two motors to lift the pistons and two motors to recharge the system, your going to have a loss through friction, but if you use two motors to lift, but 4 motors to charge, you should gain back some of the loss from friction, back from having extra generators suppling more electrical energy back into the system, giving you back a much higher efficiency rating, and if you put capacitors in line with the generator's, you will get an even higher rate of return, because capacitors store energy, but also reduce the back emf produced by the generator coils, so your efficiency increases, when using capacitors. 🤠👍

Cant help thinking like this: How much energy would i take to heat water to steam to rise the cylinders and how much vacuum will it produce when steam turns back into water.... The gain i can see in such a contraption would be that the steam does not have to do much work when filling the tubes.

Ever heard of springs??? Way more efficient in this case

Well Done.

You just can use a single spring insteed all of this)

I can’t imagine what a commercial scale system would cost

would be great to get a link to the original channel from which that video was stolen

try using differences in daily air pressure/weather and heat fluctiations to generate power.

Additionally, you can even increase the amount of stored energy by placing it underwater.!

I'm not all the way through the video yet. I see there are some admonishing comments. It is an interesting piece of technology. I like it. It's definitely food for thought. If CAES is so easy for everyone, why isn't everyone doing it? This to me seems like an interesting approach that can have implementations in some contexts where it might even be a great choice. I realise that what people have said in the comments makes sense yet I do like the approach taken. I think it's cool anyway.

Absolutely cool. Mate, you could turn that into a business. At least until some company in China starts producing them for cheaper, you could make quite a bit of money. Yeah... I know... I'm boring.

When you scale this up you will find out that cylinders don't like vacuum, especially steel will yield to buckling.

Please forgive me if it is nonsense, but I have a few ideas: Would compressing air instead of creating a vacuum work as well / would it be less or more efficient? Could you increase the efficiency if you minimize friction beetween the tubes and seals? Great project, really. I am not a professional in this area, but with stronger materials etc. this seems like it has potential. Cool.

Petrol is not a fossil fuel 🖕

RIP

Guy, you should think about using changing of atmosphere pressure for electricity generating. Really, you have almost all necessary components. They can be reassembled for electricity generation.

getting such a high efficiency with the first prototype looks very promising

Pump hydro is not as efficient as you stated. The efficient a pump is only 65-70%. And the reverse generation side is only slightly better.

Why not used springs instead? 🤔

Add it to highways and have the cars rollover batches of suction cups to produce energy BUT if you let the electric companies do it we will never see the savings. Just higher prices

30sec in.. and this "green" energy movement has also led to probably more emissions, extensive exotic metal mining and actual pollution such as solar and wind farm's garbage that's hardly being recycled. It became an actual environmental concern😂. As for the concept. Vacuum has its limit ~1 bar of energy. With the same amount of materials used, it's makes more sense to store positive pressure going wayyy above potential energy of atm pressure.

how much energy could these things store? you step on it and it s charged...

There is a law that allows the United States government to confiscate and keep secret any patent it deems as a risk to the economy or to the security of our country. There are over 6000 patents kept secret by our government. things like cars that run on water and free electricity for everyone but they keep it secret because they think it will destroy our economy if everyone can be truly free. worse yet many of the inventors, who filed those patents mysteriously disappear, or are mysteriously found dead

Very good idea find a student that writes proposals and go for it exterior vacuum tank ad ons for capacity and scale is easy

Honestly feel like since he didn't need the full force of all 8 cylinders to turn the motors to generate power,why not split the force as needed which would increase run time and overall output theoretically.

its good because you dont need hard to get matriels like lithum and what ever

Cool, but what about using higher pressures and more volume? In other words, using a scuba tank would be more volume and allow more energy to be stored and thus released. Same concept, but from vacuum to 1bar to 3000PSI.

Why do you specify power as a unit of energy?

You missed a few VERY important pointers here... They popped up immediately while seeing the video. You can either take 'm and run with it, or I'm patenting this hahahaha... 1: Add a flywheel with freespooling clutch, so the weights going down power the flywheel. Because it rotates even after the weights have stopped, it keeps charging the battery. This is similar to a "Hit 'n Miss - engine". 2: Hook the system up to a home-battery or a serie of car batteries that can be used to power a home. 3: Let the Arduino check the battery charge so it turns on and off the entire system. When the battery is full, switch off. At 30%, switch it back on and make sure the cycle repeats! 4: Upscale with more durable materials, so people can install it in their home and always have a charged battery to power their needs, even in a power outage! 5: Realise you never have to work again if you market it properly and give me 1 euro per sold home charger LOL. (ik stuur wel een tikkie)
