After an accident I found a way to finally make a circuit that utilize BEMF to trigger transistor directly. My MJT utilize BEMF as trigger but only with EM induction.

I can implement the circuit to car coil or even coil without secondary. This is better than Joule thief for me.

I don't have scope so I don't know the duty cycle.

The circuit:

This circuit produce spark better than my 555 that also consume 100mA at 12V. The spark that spreading is usefull for ozone maker/ionizer.

Thank you. I can make it work.

I see that it can produce more than 500V :).

HEHEHE yes the simulator does come up with interesting results, however it does not show any radiant energy. The programmer uses formulas to replicate some of the "anomalous" behavior of coils. A collapse of an electro magnetic field cannot produce more electrical energy or potential than it took to create it due to losses, so what is happening?

What is happening is charged "particles" are being attracted to and repelled from the coil, some of these we are able to collect. This is the radiant. It is radiant because it does not need a conductor or anything else to transfer its energy across a space, It even works in a vacuum.

I put Particles in quotations because they are not really particles. whatever they are does not appear to have mass but it does have energy.

I put anomalous in quotations because standard electrical theory cannot explain where the energy is coming from, so it is an anomaly to electricians.

Quantum physics does allow for this but i am not well enough educated in this subject to explain it hehe.

The simulator isn't perfect but it is a good way of passing our circuits round in a way that we can all understand

It still surprise me how the simulator can show how my circuit work. That is very good simulator :).

I found that diode play crucial role in the circuit. I observe that I can get more measureable voltage by using diode that can completely block battery voltage. Diode performance vary, and usually the fast one block less.

Since Bedini mention that the current that charge the battery can not be measured, I may go the wrong direction. However a test with IN60 definitely show the inferiority of fast diode when charging battery.

Pulse charging is beneficial for batteries, it does not matter if you use normal electricity or radiant energy.

I believe short duration pulses of high potential cause a radiant field in the battery improving charging efficiency by "pumping" the radiant directly into the battery.

Radiant pulses of high potential do exactly the same thing.

Radiant pulses do not have any amps so we are charging the battery without any amps. The negative resistance effect, the battery is charging with potential only and no current flow.

If you measure the power output of a radiant charger, there is not enough power to charge the battery yet it still charges. The battery is charging for free.

We are using real power to pump the radiant but when we measure power going into the charger and compare it with the power we can get out of the charged battery we find it is near to 100% efficient. this is much better than we can get using a direct normal charge even when we pulse it. We now have a gain that is above the efficiency of the device that we are using because the device will be much less than 100% efficient.

There is still more energy to collect. By pulsing coils we get magnetic energy, this can be used to power a motor so that we can get mechanical energy as well.

When we add the power collected in the charging battery to the mechanical power of the motor (work done) and compare that to the input power we have an anomaly. The measurable power on the output is more than the power of the input.

By using a diode and transistor we can cut the pulse to a minimum duration therefore using the minimum amount of power. The rise and fall of the pulse is very important as well, it needs to be fast to maximize the radiant output.

The leaky pipe problem.

Radiant cannot be held in the wires and will leak out into the environment in one form or another, you may have noticed radio interference when operating your device. If our electronics are too slow much of the radiant can leak out. The same goes for the wires on the output, we need a low impedance so that the radiant will flow to its destination and not leak out

Measure the input power of your device using a fast and then a slow diode and compare it to the power you get in your charging battery. I think you will find that the slower diode gives a higher input power and a faster charge time but when you look at the charge efficiency, it will be lower.

In an ideal setup your input power will be 1/20th of the amp-hour rating of your battery or less, again you will get higher efficiency of charging.

Thanks.

I don't have pulse charger, but I definitely see better charging on Nicad and NiMh, also recently on lead acid.

I want to experiment spark gap charging but unfortunately the spark disturb monitor and keyboard.

I observe current between 10mA to 250mA depend on input when charging with radiant. 1000mAh nicad will be charged less than an hour with 250mA one. about two hour with 100mA. This is considerably faster than specified in sanyo nicad manual (14 hours with 170mA).
http://battery.sanyo.com/en/spec/cadnica/N-1700SCR.pdf

I never calculate battery output. But it seems my system is not COP>1 yet.

I am now combining my sting oscillator with my correa's converter. It produce twice more voltage now but with around 30% more input current. will post the simulation shortly

When I tune the device today I found that this circuit has similar characteristic as my MJT. That is, the input current will reduce when it produce the highest output voltage.

I rather confuse with fast and slow diode. I once did an experiment too:
http://www.youtube.com/watch?v=ATvjBgMYAlY


Now I use the one that give me the highest measureable voltage. The one that show the higher charging voltage on the battery. Since higher charging voltage will increase the battery voltage faster.

Ahhhhhhhhhhhhhh now I see what you are doing.

Its not the radiant that you are using. You are bringing the coil to saturation and using the inductive kickback to charge the batteries.

There are pros and cons to this technique.

The pros are

you are able to charge bigger batteries with a smaller device

you are pulse charging the battery

More efficient than a standard charger.

Cons

you are using the amps to effect the charge

Heat

lower efficiency than the radiant chargers

you will find that if you have two identical batteries and use one to charge the other only around 80% or less of the power you put in ends up in the charging battery.

The trick here is to switch off the supply of power as soon as the radiant appears. Let the potential do the work not the amps. it is slower but better on the batteries and cheaper to run too.

Bedini's big machine only draws 10 or so amps even with ten large 7 filar coils. if he saturated the coils it would be drawing 100 amps+. His motor efficiency would be a lot higher but his charging efficiency would be a lot lower.

It is true that the simulator only shows how inductive kickback works and cannot show the radiant that flows in the opposite direction.

Shorten the duration of your pulse to the point where you still have the voltage but you are drawing the minimum amps possible.

I don't think I reach saturation. I use coil with less than 1 ohm resistance and the input current is under 400mA at 12V.

I don't observe heat in my charged battery. The transistor do heat up.
