Thanks for the reply , i really appreciate it

Gokul43201, have you checked your private messages , i sent you one on feb 7th. i don't know who else to turn to for an answer, the gap is adjustable and is essentially the same @ 0.460" , for both tests. my test coils are 0.390" thick. i have several. 0.035" space top and bottom.. this...

yes i have diagrams , but would like to ask first , are my thoughts on doubling the thickness , and hence getting double the voltage , essentially correct?

what are you trying to do? the input to your AND gate is from the same source, your output will allways be a logic one..

I am designing a three phase permenent magnet generator , and have a question. as a magnet pair passes over a coil , inducing a voltage, that voltage is most dependent on ? 1) the angular velocity ( that's a given) 2) the pole strength 3) flux density 4) energy product. 5) thickness of...

Good point Willib! what exactly is a flow battery? Willib replies : a flow battery is an electrochemical device that uses vandium ions to tranfer charge held in solution to terminals in an ion exchange unit. willib tell me more: :smile: willib replies :Well a flow battery is a technology...

Do a google on " flow battery " this woman from Austrailia did some recent work with them ,really interesting stuff.. in Japan they use them to supply Grid Power from a windfarm ..

How about the new Honda FCX, which uses a bank of super caps and has a hydrogen oxygen fuel cell , damn what a combo ! http://www.world.honda.com/FuelCell/FCX/ultracapacitor/charging/

i read the article , but can not figure how they are going to get power from osmosis.. below , this was also on the same page anyone see anything wrong with the statements above..?? for one thing the aurora is an effect of solar wind interacting with the magnetic poles of the planet , its...

because if your device liberated H2 & O2 you could burn that too.. Say that you have this large pile of Ca(OH)2 , you might need some way to get the stuff in the center to the outside , where it can be heated . or just heat smaller portions of it..

94.62 : 1 thanks fred .. how did you know it was a motor :wink: :smile:

they are number of teeth.

Hi , is anyone studying gear ratios?? i need some help with calculating the final gear drive.. i've calculated it at 94.97:1 is this correct??

Very interesting proposal.. it sounds plausable to me.. one question , are you saying the sun does not shine in winter in sweden? you seem to be (roughly) at the same lattidude as southern alaska.? another question , during the heating process ( with sunlight) is the hydroxide given off as...
