Re: transformer/rectifier question

from whai i know about transformers, A 24v 10 a transformer can deliver that much power (240 watts) indefenitally.As far as the efficiency of diode rectifiers, i think it is higher than 60%. Brute force filtering is nothing more than high value caps. They may use a lot of current initally charging, ...

Re: Sprinkler Controller Indicator

I would try a light bulb in series with tha counter. Initally the current through the counter would be high enough to pulse it,but after the filiment heats, it would be limited so it does not overheat, use the lowest watt 12 volt bulb that will pulse it.

Re: A watts question.

What's a watt? A watt a measured amount of work.You can read them on the wattmeter on your home. A horse can lift 550 pounds one foot in a second and if it applies that amount of effort attached in an efficient generator he will be able to light about ten 75 watt light bulbs till he stops. The avera...

Re: OPNIONS WANTED sounds too good to be true

something i'm not sure about is the efficiency of the magnesium extraction process, or that of it converting it back to electricity, but i know a well designed electric motor is at least twice as efficient as it's otto cycle competitor. A gas motor uses 1/3 of its energy to create mechanical power a...

Re: OPNIONS WANTED sounds too good to be true

Engineers of Hitachi Magnetics Corp. of California have stated that a motor run solely by magnets is feasible and logical but the politics of the matter make it impossible for them to pursue developing a magnet motor or any device that would compete with the energy cartels. this was taken from the a...

Re: Current source

you can use an lm317 as an adjustable current source within those specs. You should be able to get how via texas instruments app data.

Re: Capacitance

you should find out how much current the motor uses by powrering it with a battery in series with an ammeter I think you need a shop type 50 amp battery charger to run it,a transformer that can deliver 40 amps at 35 volts is 1400 watts if it don't weigh 50 pounds or thereabouts it aint gonna deliver...
