Veljko Milkovic - Hand water pump with a pendulum

[karvak1492]

Ideja: umesto tega stvaite ljuljacku. U ljuljacu neka sednu deca i tako sa razonodom cete dobiti puno vode, koju ste pre morali ispumpati teskom radom... ;) Tako spojite razonodu sa radom. Ljuljacka je jedna vrsta fizickog klatna... dete=30 Kg+ljuljacka=10Kg kad se klati zamislite kolko vode mozete ispumpati tako veoma jednostavno i bez napora i teskog rada ;)

@karvak1492

Jos 1998. godine Veljko Milkovic je predstavio ideju da se kao klatno koriste decije ljuljaske u parkovima za zalivanje i navodnjavanje.

[ferenckarvak]

@Ulianot S obzirom na genijalnost ideje, neznam da li su praktikovali to na nasim decijim igralistima bilogde :( Voleo bi videti video o konkretnoj primeni. U 3DSMAX Reactor simulatoru sam napravio model dvostepenog mehanickog oscilatora: [youtube.com]/[watch?v=][rSZNV­26IS9Y] (ukucajte bez "[" i "]" znakova).Pomocu program mehanickog simulatora moguce uraditi razne eksperimente mehanickih uredaja. Prednost: besplatno je i sto je najbitnije, verodostojno.

[remy130]

ne razumijem ovdje neku svrhu ipak moras njihat taj teg isto ti ga dodje ko da i pumpom pumpas

[karvak1492]

@remy130 jednostavno objasnjeno: ovde sa puno manje ulozene snage (rucne) mozes dobiti istu kolicinu vode iz zemlje, posto glavni izvor energije za ispumpavanjem vode obezbeduje gravitaciona sila zemlje. Znaci puno lakse ispumpati istu kolicinu vode nego sa klasicnom metodom ispumpavanja. Fizicko klatno je genijalan stvar za konverziju gravitacione sile zemlje u mehanicku energiju.

kakav izum covece,i prakticnost u radu,bravoo

[lostbuffalo]

same way an oil rig runs only the pendulum aounterbalance constantly rotates

[overunitybill2009]

A flywheel would do the same thing.  without the herki jerk nature. A bicycle with an eliptical sprocket would help.

[planetdarwin]

don't they already have windmills that do this more efficiently?

[kyclay58]

Wast of my time. All this just to pump water. You can do the very same thing by simply eliminating all this and pumping the handle on the very same pump. No more work than standing there moving the pendulum. If the pendulum will move on it's own this guy sure did not demonstrate it.

[tenkikun]

I think the pendulum is too light or too short arm to it.

both things would give the water some good flow.

[FCKEVRY1]

Useless! I don't care what anyone says. This configuration, according to all laws of physics, is making the task harder and slower. This is really REALLY stupid! I know what the milkovic oscilator is. This isn't it. Not even close.

[shagster1970]

This video is about 3 mins too long.

[Turbomaxgt]

crazy:)

guys how to applay to this weight like in an old clocks,that u have to pull contr weight down to reset it and keep going in for next 12 hours?:)

[FCKEVRY1]

This video is even embarrassing to watch!

[FCKEVRY1]

Am I the only one who sees that this machine in it's configuration is completely useless. You're supposed to able to let go of the pendulum and let it use momentum to do the work for a while.

[Ulianot]

@FCKEVRY1

@FCKEVRY1

The demonstrator of this pump didn't keep the pendulum correctly. It is not necessary to follow the pendulum constantly. You just need to occasionally add energy to the pendulum like Veljko Milkovic demonstrated in his YouTube video "Veljko Milkovic - Laboratory pump with a pendulum"

Milkovic explained this wrong demonstration in his video

- watch from 24:50

[earthga]

@FCKEVRY1 did u ever try to pump the water on this pump? it is much harder than swing the pendulum! and 'Ulianot' is corect too.

[sutadebastos]

@FCKEVRY1 : hahahahahha! i thought am the only one who noticed it!

[FCKEVRY1]

Am I the only one who sees that this machine in it's configuration. You could be using a hand pump to move the 2 inches you need to get the water, but instead you put a pendulum that's too short to provide a result and noe you need to put in MORE energy than a simple hand pump. I know how these oscillators work and it's a shame that people think it's just a pendulum in a any random configuration and an arm. This device defeats the purpose of an oscillator because the builder in an idiot!

[nicbordeaux]

What the heck, everywhere I go it's Mr Milkkovich double stage (bs phrase) oscillator this, oscillator that....

Now if thispump is more efficient than a normal long handle actuated by a person, hook it up to a electric engine, and measure the darned efficiency improvement. It's not comlicated to do. Or it's not more efficient in absolute terms, just for human use (there is a difference betweeen a human and an electric engine yawl know ?)

You guys have me beat : proof !!!! Move on, improve!

[runaway9413]

I think it would help if he explained what problem he is trying to solve and why this is a better design

[x250f23x]

You should make a big one that has a swing, that way you could have the kids swing and bring up water. Win-Win situation!

[Nabo00o]

Yep, right now I think he looses much of the gain this could make because of a relative small pendulum, too much is absorbed in friction and such. Plus its easier pushing a longer pendulum at a small angle than a short one at almost 180 degrees. Efficiency follows with that...

[FCKEVRY1]

Ten you can do the same with a teeter-totter, merry-go-round...heck build an entire playground around it.

[ihearvoices22]

@x250f23x i would have to say that is a really good idea.

[DragonFlyback256]

@x250f23x

Either this or one driven with a roundabout. xD

[kurpochelo]

the useful power is:

flow rate: 20 l/min = 1/3 l/s

mass rate: 1/3 kg/s (1 liter of water has a mass of 1 kg)

potential energy increase: 1/3 kg/s x 9.81 m/s^2 x 3m = 9.81 W

Big DEAL!

[causevskinikola]

Everybody who has tried to pump water knows that this shown here is over unity.

[meskalino]

it's not overunity, it's converting gravitational potential energy to kinetic energy. great invention, so simple too, anyone could build one

[filozofNS]

ROTFL

[rayunseitig]

This a great workout.

We should harness all the free energy people use on exercise machines in gyms and spas.

Come on over to my place and I'll let you pump water and generate electricity for a modest fee.

Hmmm

[Nabo00o]

Genius :D

[WarzSchoolchild]

Bravo! Now let's see a bigger one, with a child's 'swing' as the 'pendulum'!:-) Make useful work into play.

[RHEAD100]

Damn !!!! I like that idea. Now I just wish I had made mine bigger than I did. It is only 9 feet high and weighs over 900 pounds with a 130 pound pendulum. Check out the videos on my site here on you tube.

[WarzSchoolchild]

A SMART SALUTE! Sir. I just watched your video. Science is about 'hands-on' experiment, confirming or refuting 'Theory'. Now it comes to mind, that centuries of hard labour and experiment by 'Clocksmiths' have devised methods to swing a pendulum. i.e. Grandfather Clocks. If 'over-unity' is indeed revealed, a small version could provide the power to swing both itself and a larger version. Perhaps pneumatics? with an air reservoir from salvage, powering both? Hypothetical, but worth a try!;-D

[lookatthewholething]

Funny, I thought exactly the same thing. I sent a copy of this video to empower playgrounds. They made a electricity generating carousel for kids so thought they could do somethig beneficial with this as well, like you said, making a swing that pumps water.

[WarzSchoolchild]

Hi 'lookatthewholething' I am Chaplain with the Catering Corps, Dad's Army R.M.P.T.A. section. We Police the Kitchens!

A nice heavy ten tonne pendulum, preferably two swinging in counter oscillation to balance structural loads..blah.

The pivot is sprung and damped with knitted steel sock dampers inside the springs. Result the pivot box gets hot enough to grill burgers, boil kettles,etc.

Guests asked to give the pendulum a gentle shove now and then. Conservation Laws need scrapping! NOW!
