Chalkalis Gravity Wheel

[FatChance!!!]

The motor advice

That's good but did you read and understand my explanation how your pendulum contrapment works?

[conradelektro]

just 2 cents, trying to harness the gravity power on a longer shaft. The setup seems to work, now lets do some measurement to see if Milkovic and Chalkalis together can do some usefull work.
any idea ?
Good night

Very nice Milkovic pendulum and a clever way of driving it.

But I do not understand how you are driving the Chalkalis wheel. In the video you say that there is small motor? Would you mind to explain that?


What to do with the "NOD" of the Milkovic pendulum lever:

Milkovic suggests in two of his patents to convert the "nod" into electricity by moving a magnet in relation to a spool.

( http://www.veljkomilkovic.com/PatentiEng.html )

If the "nod" (at the end of the lever, where it strikes the confinement) is strong, one could move a very massive and powerful neodymium magnet (shaped like a rod) in and out of a big spool. The magnet induces an alternating current into the spool which could be rectified with a full diode bridge (and a big smoothing electrolyte capacitor) into fairly good DC.

Measuring the DC Voltage over a resistor could allow to calculate the electric power generated. Of course, this "dynamo" has losses, may be only an efficiency of about 60%. But it would give a rough indication of how close on comes to "unity".

Imagine a horse-head-pump as used to pump oil http://en.wikipedia.org/wiki/Pumpjack, where the travelling valve is the magnet and around it not the oil pipe, but the spool.

I hope one can understand this cryptic way of putting it.

Hi Conrad

this set up is a test to see how i could power the Chalkalis assymetric weight.

So i simply took one of my other pulse motor test. I enclose here a video where you can see this motor working and the shematic if you want to replicate.

Than i simply remade a rotor without the 6 magnets but only 2 bigger and glued on one side of the rotor. So these 2 magnets are so to say a selfmotorising pendulum.

I did not try to test any output power at the end of the lever. But i think a solenoid and a magnet could be a good solution, as per the Milkovic's patent you mentionned.

Hopes this help

good luck

Even more impressive than I imagined.

You got rid of the ungainly vertical lever of the Milcovic pendulum and you replaced it with a very efficiently driven unbalanced wheel (pulse motor principle). Very compact and an amazingly smooth running machine. It runs like clockwork and like all good ideas, it looks so simple.

Great stuff, I feel the urge to replicate your set up.

Does anybody have an idea how efficient it is (as a dynamo) to move a powerful magnet in and out of a big spool?

You see the slow speed and the relatively short stroke of the nod
(in Laurent's video http://www.youtube.com/watch?v=lr69L9fJpY4),
is this a big draw back for the dynamo effect?

P.S.: Why does it always happen? I do something (like now I play with Joule Thieves and self made batteries), and then I see something intriguing which lets me drop what I am doing and I start something new. (And of course, nothing gets ever finished!)

Hehe Conrad

just for thinking

Imagine that you will power your JT with your self made battery, than the JT recharge a supercap ,which recharges a battery which powers a pulse motor which power a Milko pendulum which power a solenoid ,which of course charge a battery and by doing this you can recycle the kickback energy of the pulse motor to recharge another battery which can power a Garry stanley motor and your electric bike and ............

So you see don't worry about having an open mind and be interested in all these very interesting stuff. As we are not pro and have the great chance not to have to obligatory get results, my advice is try, try try and have great fun. An wy not once perhaps a big surprise.

Good luck
