Cyclone Posted October 2, 2012 Share Posted October 2, 2012 Ummm..No!...... Um, yes, the principle is the same. If you discounted friction then a spinning bike wheel (stood upside down of course) would never stop. Link to comment Share on other sites More sharing options...
medusa Posted October 2, 2012 Share Posted October 2, 2012 Ummm..No!...... So what is it that stops the bike wheel from going round, other than friction? Link to comment Share on other sites More sharing options...
skinz Posted October 2, 2012 Share Posted October 2, 2012 Very basic school boy/girl physics. Energy extracted would be less than that invested. Not taking into account the energy that would be needed to manufacture it. Link to comment Share on other sites More sharing options...

PeteMorris Posted October 2, 2012 Author Share Posted October 2, 2012 Would it be too much to expect to ask you to all stop attacking me! Giving me todays physics lesson and treating me as though I'm a complete idiot! I know, it's not perpetual motion, I've conceded that long ago! I didn't claim it was, I just posed the question which was answered. Link to comment Share on other sites More sharing options...

Well from my cycling days, I got bored with it generally, and used the brakes! Ooops...sorry that IS friction! Link to comment Share on other sites More sharing options...

Once again you have revealed those who lack any sense of humour and who having made their point, return repeatedly to state the same thing over and over and over and over..... ... you have performed a public service by keeping these armchair scientists occupied for a few hours. No-one with any previous knowledge of your entertaining threads would think that you considered perpetual motion as a serious issue. Thanks for once again making the effort to keep the forum alive - otherwise we would all be talking about wheelie bins or the weather! Link to comment Share on other sites More sharing options...
Obelix Posted October 2, 2012 Share Posted October 2, 2012 Aaaaaargh...I concede!...it's not perpetual motion!..:hihi:.'I' never said it was!!!!! I still think it's fascinating nontheless! That second machine looks like it could go on forever (excluding friction) (said in a whimsical way!)!!! If you want something that looks like a perpetual motion machine (it isn't as has been said before many times) but is nontheless fascinating, then look up the Oxford Bell. This is a bell that has been ringing constantly for about 150 years now... powered by a pair of sulphur coated Zamboni batteries... Link to comment Share on other sites More sharing options...
