Bar Magnet Tolerance

Poll: Bar's penalty was appropriate

“That place is cancer. It needs to be closed down. It’s had problems since it opened. None of the other bars have as many problems as this place combined! It’s always too crowded. You have people hanging out in the street in front of it that you know are not from Petaluma. (They make it clear, claiming they are from Santa Rosa or Vallejo. Sometimes even Richmond, and that they ‘own this joint.’ Close it down.” “Out-of-town party people have hijacked Kentucky Street on weekend evenings. If I owned a business in the area, I’d resent having to wash the ‘after effects’ off my sidewalk every Monday morning. As it is, I never walk down Kentucky without carefully watching my step even during the daytime. May this punishment serve as a lesson to all the bars in the area.” “That place is so ‘un-Petaluma’ that I am surprised it took this long. Ever since it opened, other bars won’t let their patrons in if they know they came from Rocks because they have had so much trouble with Rocks’ customers and not just because they are drunk. We have plenty of drunken people wandering from bar to bar in Petaluma but Rocks’ customers are always worse than just drunk. There is a drug problem and a fighting problem with their customers. They should shut that place down before someone either dies in there or is killed by one of their patrons. Go back to Rohnert Park — that is where Rocks belongs.

Simple generator: electric generator for science fair | The Word ...

1. all metals are full of movable electrons. In physics books they call this the “ocean of charge” or “the sea of electrons.” The sea of electrons reflects light and gives a metal it’s shiny silvery appearance. A metal block is like a tank full of electrons. A metal wire is like a pre-filled pipe. No bubbles.

2. Don’t use my project, it’s a bad design for wind power. Try these instead:

Bit.ly / Uu1hy

bit.ly / rkXOM

i was thinking of doing this full scale by using neo supermagnets and doing a sort of vertical wind turbine with this by putting the cardboard sideways

2 questions

1 where do you get a negative charge from this generator since to light the little bulb you need, negative charge , and positive charge.

2 how many times should i wrap my copper wire around a larger wooden type of structure using neo super magnets efficient enough for that the wind could efficient produce the electricity pheww

@OCoptimusconvoy why not just use one turn? Or ten? It’s because the number of turns determines the output voltage. (Well, that and magnet strength and RPM.)

If you want to spin it with fingers, and want to light a tiny bulb at 3/4 volt, then you need about 250 turns. That’s the bare minimum. Or instead, just spin it 10x faster somehow. Or use expensive neo supermagnets in place of ceramic magnets. If you could spin it at 3600RPM, that’s 60Hz, and you could step up w/transformer.

@ncranfill Click on the main site and go see the links page. Look under wind power generators, 6KW by Otherpower. Hobbyists are always building their own 1000W generators. These are pancake style, and they only need about 10 lbs of neo supermagnets.

Otherwise, just buy a 2HP AC induction motor and use it as a generator. (You have to look up the website about “induction generator” projects. You have to add a big capacitor to make those work.
