re: Definition of "Gravity is conservative" ?
Hi all,
Ralph’s bucket up stream,
Well before Newton and the rest of then, people have enjoy sailing up wind ( forward motion against a force), this is because of the mechcanics of erodynamics, which is all most the same as hydrodynamics only the gas has more density, so if the bucket is designed and used correctly then there is no law to prevent a object travelling up stream, just as a lot of sailing boats do in a lot of locations, some times going up stream and against the wind, this is on the same lines as John Collin’s thinking some people may say the wind is not a conservative force, but is gravity a Conservative Force or a Generative Force, as far as I can see gravity is renewed, every time I drop something and pick it up again I find that the Gravity has been replaced! This begs the question does mass produce gravity, does mass have X amount of energy or a constant X amount of energy? Some people call it a conservative force and they do not even know how it is produced! Come on lets be honest!
In short the path taken and the advantages used should be considered before the impossibility of the scenario is used to down play the mechanical advantages in use, there are to many people on this forum that can only see that the path and energy of a weight reset in a wheel can only be in a up and down side to side singulars path, we have so many mechanical tools at hand that there should never be its imposible said until every combination has been tried, this would be more sciencetific than making a guess.
Regards Trevor

re: Definition of "Gravity is conservative" ?
I made the following devise from an old illustration of a sailing ship that used a similar devise. The triangle on the end of the tether is rigged with a bridle and thrown overboard. The triangle alternately dives under and leaps out of the water as the boat sails along. This raises and lowers the plunger in the bucket of nasty laundry and does a fine job of clothes washing. When long distance sailing with a 6-month old this was a God Send.
This set up also worked well attached to a manual bilge pump.
I post it here to demonstrate how dipping in and out of the gravitational stream might be used to good effect although gravity and a river (or ocean) are apples to oranges it may spur the little grey cells.

re: Definition of "Gravity is conservative" ?
Conservative gravity or what we call mass or weight, will mean:
- no dissipation
- passive division
- behavior tending to rest and accommodating passively
If allowed, the mass, or body, will try to 'travel' until earth center.
This conservation is said by newtonians as the main reason to explain the impossibility of 'g' devices.
I use to say that more or less conservatives are the resistances against the theoretical mass travel to earth center. If one need to RISE the mass, one also can say that this is a resistance... not conservative resistance.
Just trolling.

Alan, do you agree with the standard definition of conservative gravity?

re: Definition of "Gravity is conservative" ?
Your optimism is a ray of sunshine as always Alan.
Does Earth's Gravity effect rotating masses (near the surface of Earth) the same as it does mass moving in a more straight path?
There seems to be a good deal of debate on the subject.

Alan, sounds like you don't subscribe to any definition of gravity?

Ovyyus, hi!
Please, be advised about something wrong:
your little Da Vinci man doesn't stands in same position.
Someone had to tell about this.
( a good will member. 8)
Best!

Thanks for the heads-up Murilo. The little man trapped in the wheel obviously seeks a means of escape! :D

re: Definition of "Gravity is conservative" ?
Alan, are you saying you will be producing a working wheel this year ?
If you think you have an overunity device, think again, there is no such thing. You might just possibly have an unexpectedly efficient device. In which case you will be abducted by MIB and threatened by aliens.
re: Definition of "Gravity is conservative" ?
Yep, at least one every year since the dawn of time with no clear end in sight :D
