Joule Thief 101

Instead of the stupid worn-out Joule Thief ad nauseam, I suggested a project for a circuit that is purpose-designed to drain a battery of as much energy as possible, and also keep a LED lit at a certain minimum brightness.  Nobody said anything, just blank stares.  How about an egg dropping competition then?

I already have that circuit--the Cool Joule.

It will pull the battery down to less than 150mV.
It will run for up to a year on a full 1.5v AAA battery,while recharging a second.
For a higher light output from the LED,simply remove battery 2.

A very simple circuit.
L1 and L2 cannot be hooked up the wrong way around,as the circuit dose not rely on inductive coupling between L1 and L2 to operate. Each coil must be hooked to the specific
connections on the circuit though.

@ PW

Dose this look like it operates using the miller capacitance effect?

Yes Cavity resonance would seem a path to results.
your friend Robby squeezing 1HP for every 2CC's of displacement with a Huge standing wave.

here is a very simple Cavity resonance device which has always tickled My Fancy.

That's great, promoting a fake "resonance" device with a fake clip from a group of people that are universally recognized as fake scam artists.

Go Back to your Canadian scam promo's ,

here we have cavity resonance doing things it should not do in an ICE ,*1 HP per 2 CC's displacement.
Utilizing resonance to do this,[something you were clueless about yet felt the need to holler BS and call
Brad an idiot.

One Man's BS is another mans Curiosity ...
cavity resonance needs further investigation !

Just ask the Bug with a specifically designed cavity fist that Knocks photons out of orbit  causing a 9000 C
biological sonoluminescent event .

Oh is he a proven scammer too ??

your credibility here [cavity resonance ] is non existent.

To be Clear ...I hold Witts in complete contempt .

not so ..this claim about cavity resonance and the things which are truly possible .

The Bug Pings a cavity and gets 9000 C from water .

Ultrasound pinging a cavity ......?

Wow wee, if you put air into a cylinder under pressure it helps you get more air into the cylinder and therefore you can put more fuel into the cylinder for a bigger bang.  That's really amazing out-of-the-box thinking that the PTB don't want you to know about.  But the actual engine itself, the pistons, the valves, the camshaft, the crankcase, the ignition, etc, has absolutely nothing whatsoever to do with resonance.

And then you roll out the pistol shrimp for the 30th time - which has nothing to do with resonance.

The below linked paper is from the era where indepth research started on diesel engine's.
Once they started to understand what was going on within the engine itself,large advancements where made,and today the diesel engine can be found in race car's,where there performance is up there with the gasoline engine of the same cubic size.

High performance diesel engine's are common place today,and in the future i see them surpassing todays gasoline engines in performance and efficiencies.

As you will see in this paper from 2002,research and results are found and given on the cavity resonance inside the motors cylinder. The cavity in this case is the bowl found in diesel piston's,where resonance of this cavity plays a vital roll in engine efficiency and performance. These resonant frequencies are at the human audible range-between 10 and 20 KHz.

There is also a lot of information out there about the resonant vibration's of the ICEs cylinder wall's,and this also plays a vital roll in heat dissipation,and efficiencies.

Back when i was doing my trainee ship,there was very carful calculations made on the cooling fins of the two stroke air cooled engine,so as they did not go into resonance during the engines rev range. In the early day's,cooling fin's use to break off cylinders for no reason at all--or so they thought. But it was later found that some that were of the right size and shape-in relation to engine vibration,would go into resonance,and reach an amplitude that high,they would just break off--much the same as the wine glass reaching an amplitude where it can no longer hold the amount of built up energy.

Anyway,back to internal resonance of the ICE.
