~CHILD's PLAY~&~bye-bye MAINSPRING~
NICK: It just occurred to me that a Multiple-water-tank-tower AS THE STORAGE DEVICE rather than using the 'spring-idea' at all might be a simple obvious solution to 'over-night' power storage. A Gyro-Centrific-Inertial(maybe generator also) device on the order of A CHILD's TOY PLUNGER TOP that could be simply 'plunged' down by the dropping water-tank elevators (concept) might keep a sequentially contant power-drive process moving right along through the evening. This would apply simple-gravity to spiro-centrific inertia rather efficiently.~JH~ > From: nick([email protected] > To: [email protected] > CC: [email protected] > Subject: Re: [Vo]:Clockwork&RubeGoldberg > Date: Thu, 3 Sep 2009 13:34:06 +0100 > > Hello Mike, > Yes, it doesn't look like big springs are able to be used > for storing much.
