RESONANCE EFFECTS FOR EVERYONE TO SHARE

    The ohm rating of a coil is it's impedance rating.  How much total resistance there is to a sinsuoidial dc pulse.   Like 8ohm speakers will cook if you give them pure dc and just figure in the i2r losses like it was an 8 ohm resistor.  Regular resistors do suck because they convert epower to infrared em power unless you are going to use the heat and the magnetic field energy is ignored in them.  Another thing is that the hotter they get the lower the resistance so the hotter they get. I suppose we could alter the cord going into an electrical resistance heater so it goes through a primary of a transformer and use the secondary of the transformer to drive another heater.  Or how bout making the cord just a series of primaries.  And then all the secondaries shorted out to another heating element.  Should get more bang for the buck.  You could call it a supercord.

@wattsup,

All resistors will generate heat. Nothing to do about that. In my switch the 330 Ohm resistor is doing the
discharge of the mosfet transistor gate. First the opto is switched on and the gate charges up through the
180 ohm resistor and opto transistor. Then the opto is switched off and the charge in the transistor gate is
drained through the 330 ohm resistor. This charge is not lost. It goes to the output load since this is a floating
switch. The heat generated in the switch is removed by the use of a fan (or big heat sink). This heat is not
lost. This heat is warming up your room. But I agree with you that resistors should be avoided if possible.

Maybe later we can design a switch that do not use any resistors? I will look into this and see if it is possible.
We probably have to design our own optos also. :-) I already have tested that it is possible to light ultra bright
white LED's direct from a pin of a micro controller. If we run the micro on 3,5 volt then the LED will use less
than 20mA. The micro controller can source 25mA at each pin. Now if we use a small solar cell as the receiver
of light from the ultra bright led then the solar cell can provide the bias to switch a mosfet transistor on and off.
I do not know if this is doable but it is worth a try.

@Magnethos
That is an awesome link you posted.
If I understood it right, it is possible to send an electric current across large distances using
a LASER beem to transform the air into a single wire conductor.
Just think of the implications of such a technology.
If you want to transfer power from your house to your barn
just shine a small red penlight laser beem from the house to the barn and send the power though it.
No wiring needed.

    Telsa discovered the superconductivity effect of plasma.  The electron cloud in a metal is considered a room temperature negative plasma.  A high frequency pulsing is necessary to shield a plasma from ambient electrical noise or the plasma is excited to return to normal gas matter.  Tesla devoted many years to his wireless transmission of energy.  I believe his intent was to create a plasma dome that would create a coherent conductor between transmitting and receiving terminals.  Longitudinal wave energy or compression and rareification of the plasma the mode of energy transport and the ambient electrical noise shield all rolled up in one.

Walter Lewin has a good lecture on waves, standing waves, and resonance frequency; it's a good listen.  Also, the entire course is available in video format from MIT along with many others.
