When I was in College, in my electonics class. My teacher taught us some ways to decrease the amount of elect used in a house, and even one trick he taught us how to fool the meter into thinking you are useing less elect by boosting the wavelength of the elct in verses the elect out to closer to the original. This was way deep, you had to figure every item in the house hold, and the do math for hours.
But for lights, fans and heaters, it is much easier. The easiest one is the Light bulb, You can cut this in half real fast.. AND NO>> I AM NOT TALKING MH OR HPS.
Ok, got to consitrate.. Been years. And to many hits, and swigs. (tips Glass, ,,, strikes bowl and thinks, hmmmm A/C current on the scope has two wave lengths, One above the line and one below. I am speaking so everyone might understand here....
So anyway, on the scope, you have a middle line going horizontal. When you stick 120 volt house hold power threw this scope it will show a wave, above, then below, then above then below repeating over and over. Here is where I am rusty, You have to place a DIODE inline, and then a capacitor in cerios. The capacitor will gather energy on the energy cycly and store it, Which the meter does not read because it changes the wave length by zero. But when the A/C goes to reverse itself, the DIODE stops the flow. Here is where you save 50%... When the Diode stops the flow of elect,, the capaciter releases its strored energy. Walla, 50% power cost saveings. I know this to be true, I was in a science lab with all the electronic boards and tools needed to prove it.
So maybe I can not get some of you to believe this. But I have seen it proven.
Also cieling fans, elect stove and base board heaters can be worked with science. Some to accually save power, some others to legally,, well, just legally....
But I would never use any of this information on a grow OP.. No WAY!!!! Why give them an excuse to invade?
