...or prototype,if you have in mind some experiments,simply...reducing the friction.
The suggestion is reffering to replace one kind of friction(sliding), with a smaller one(rolling).
You can easy understand,what's talking about,if you take a look at www.geocities.com/iacob_alex/Some_Drafts/text014.jpg with the title " Free Gravity Rolling 02".

Hi iacob Alex,
That is sure one way to do it.
Take care,
Michel
Hi Michel!
If we have a smaller friction,and a possible self-turning phenomenon appears,we can detect it.
This kind of motion is an "old" one:remind the use of animal(and human sometimes...) power to move the "things"
