Free Energy will change the World - Free Energy will stop Climate Change - Free Energy will give us hope
and we will not surrender until free energy will be enabled all over the world, to power planes, cars, ships and trains.
Free energy will help the poor to become independent of needing expensive fuels.
So all in all Free energy will bring far more peace to the world than any other invention has already brought to the world.

The past several pages have been quite revealing
psychologically as the "struggle for dominance" has
become increasingly transparent.  It seems that Miles
has acquired a small following of "groupies" to augment
his efforts.  This is not too surprising as Miles is an
accomplished wordsmith with considerable persuasive
skill. ;)

The "opposition" though is holding up well and making
a good accounting of its prowess as the struggle evolves. :)

It looks as though the tailspin leading to the crash of the
weaker arguments is taking shape.  Will there be a recovery? :o

Carry on gentlemen - this may be a new record for length of
discourse.  And, it is entertaining too! 8)

When in a panic, just say "Aardvark."

Wine Glass Questions - Answered

How does a wine glass resonate, what is the mechanism?

The wine glass resonates by cycling energy back and forth between two forms, kinetic energy and potential energy.  The instant when the glass is not deformed, the glass is moving at a maximum velocity and all of the energy is stored as kinetic energy in the form of a moving mass.  The instant when the glass is at its maximum deformation, the glass has stopped moving and all of the energy is stored as potential energy in the form of a compressed spring.  In between these two states, the energy is stored as combination of kinetic energy and potential energy.

How is the resonant frequency of a wine glass determined?

The resonant frequency of a wine glass is determined by a combination of the effective moving mass of the glass and the effective stiffness of the glass interacting with each other.  The higher the effective moving mass of the glass, the lower the resonant frequency.  The higher the effective stiffness the glass, the higher the resonant frequency.

There you go Brad.  I made it very clear to you that posting the proper rotor/magnet/timing diagram was not for me at all.  Yet you played the "spoon feeding" card against me which is nothing more than a distraction to try to take attention away from your poor presentation and communication skills.

The proper diagram is for someone like Shylo, because he would be easily confused by your two incorrect diagrams.  I uploaded the correct diagram and now you can explain it to him.

Dear minnie.
As you think i need some lessons in basic laws of induction,do you agree with MHs modification of my diagram,or do you believe my diagram is correct?.

Time for you to answer minnie--no chicken shitting this time.

You've gone full bonkers and you are still wanking away.

It is quite funny that you can keep on and on about that magical question you asked EMJ--keep on badgering him about it time after time,and yet you your self cannot understand the very laws you preach--that being faradays law of induction.

You just had to step in,and say my diagram was wrong--even admitting to being picky. You then modified my diagram to show what !you! think is the correct wave form for the !circled! time- path (in orange) for the magnets start and end position to form that sine wave you drew on the diagram.

I agreed with Bill to keep it civil,and so i will not use the words you keep using.
But every time you have tried to correct me on this thread,and call me all sorts of names under the sun,you have repeatedly fell flat on your face,and i have had to continually correct your mistake's,so as those here will learn from correct information.

I cannot believe after all this time--all your insulting smart ass comments toward other experimenters (mostly EMJ),and all your preaching of the laws you love so much,that you have no idea how to show them on a simple diagram--which you did not even have to draw--i drew it for you,and you scribbled some rubbish on it.
You preach faradays law of induction,but you screw it all up when it's comes to showing it on paper--you just dont understand what you preach,and there for have no right what so ever to judge other people-like EMJ.

Your ass should be made to apologize to EMJ,as you know less than he dose about basic induction.
In fact,i think EMJ would run rings around you in basic transformer induction-even though he dose not agree with what TK and myself say about mu little schematic and question.
The one you have screwed up is as basic as it come's,and you had another epic fail.
Say sorry to EMJ,and come back when you have learned the basics of induction.
