I always thought it seemed like a good idea to create a way to extract more energy from the waste heat generated by the various energy sources we use. Essentially, using the same design philosophy behind the triple expansion steam engine, where the steam is essentially at atmosphereric pressure by the time it reaches the exhaust outlet. Ideally, by the time the exhaust of a stove or engine reaches the atmosphere, it would be slow moving and at the ambient temperature. I imagine thermopiles, turbines, etc. in-line along the entire path of the exhaust, such that the output is a gas at room temperature, at the minimum speed necessary to maintain a draft. I don't now how realistic the idea is, but it seems like you may answer that question!
I absolutely love all your videos Rob! I would like to suggest you occasionally give us a little more zoomed in view of what you’re explaining. I’m not saying you have a face for radio, just it’s nice to see the project in better detail. Thank you for all you do!
LOVE, LOVE, LOVE Your videos! One improvement would be to cover the magnets with a thermally reflective (refractive) material and arrange them to deflect the heat back into the flame. This also has the benefit of increasing the thermal efficiency of the flame - you can get a higher temperature and burn less fuel. Also, while a traditional rocket-stove seeks to make use of the expanding air to generate an up-draft, you might instead consider ways of slowing the air flow and collecting the heat. It would also be interesting to use some kind of heat-pump to re-concentrate the energy and feed it back into the system. If you are interested in a more challenging approach, you could make a high-powered compressor with a condenser line made from a material like tungsten, which you might be able to turn it into a kind of incandescent filament, thus recycling 30-40% of the original heat. Think of it as the inverse of a cryogenic cooler. While such a thing would have been EXTRAORDINARILY difficult to machine in the past, it may be feasible using modern 3D-Printing Techniques. Whether you want to keep things simple or push the frontiers of engineering, thermocouples are AWESOME!
These last few videos remind me of an article I read a while back where I think MIT(?) built a thermo-photo-voltaic cell. Iirc heat is used to warm a chunk of metal, as the metal heats up it eventually starts to emit light and then a photovoltaic converts that light into electricity. It was supposed to be reasonably efficent too, but im sure building a high-temp photovoltaic cell is not an easy task. I also wonder if youd need to 'tune' the photovoltaic so its more sensitive twoards the red end/IR of the spectum.
i have always wondered why chinese diesel heaters for RV's didnt use this trick to power their fan. it would make it more expensive but they could sell it as a upgraded fancy pants unit. seems like you could cut the electricity demand from these little heaters by 90% at least on low or medium fan speed.
Generating from rocket stoves caught my attention. Since the ferocious motive force and velocity of a rocket stove creates such a Roar resembling the sound of a rocket hence it's got its name. I've always felt that motive Force would have enough velocity to create a Venturi type vacuum. If that is the case I feel it's possible to create a steam jet vacuum for cooling minus the steam.
I have a question, How is it a magnet loses it magnetism if its heated beyond its curie temperature, yet we have a Molten Magnetic core? Or so they say?
The Earth's magnetic field is not a permanent magnet. It's said to be generated by the motion of molten metal through electrical fields. I suspect the sun's magnetic field plays a role as well, but that's just me.
I bleeb its cause the molecular alignment changes as 4 the core it's a different kind of magnetic field the earth is an electro magnet a giant armature in space dats my take any who
Robert, why don’t you use the (JOULE THIEFF)? A simple circuit that can be stepped up to very high power Voltage and Currents. Install a few (TRANSFORMER’S) also. Want these circuits work? Thanks mate for sharing.🎉😊
Joule thiefs don't do magic. They use a relatively long duration of current driven by a low voltage to build up a magnetic field in a permeable material, and then allow that field to collapse rapidly, dumping all of that power into a very short spike. Lower power over a longer time, gets transformed into higher power over a shorter time. If you measure the power coming out over timeframes longer than the pulse rate, and do likewise for the power input, you always find that there's much less total power coming out than there is going in.
@@AtlasReburdened Thanks Robert for your quick response to my suggestion. I was hoping that this simple circuit along with a booster circuit would work well in this project. I guess, I was wrong. Thanks for sharing your experience and knowledge with me. I really do appreciate you doing this. Have a wonderful day.
I wonder if you can make an mhd that uses tourmaline to make an electric field and ions and heat to then be converted by two plates and perpendicular magnets with the electrodes coated in graphene or graphite spray.
could you combine those two ideas? Like make one device that harnessed both of those principles at the same time, double dipping on the same heat source? (I mean I suppose you could just stack them up one after another, but it would be neat if you could make a single thing do both at once.)
@@StirlingLighthouse maybe. But his voice sounds a bit more horse than usual. I've been watching his videos for over a year. So, I have a good idea of its usual timber.
Hey Robert, love your channel and long term fan. Would be interested if you have any tips on how to generate biochar for small scale residential uses and agriculture + carbon sequestration. Ive been working on testing simple pit style, but i want to move to some kind of clay oven so that i can fully combust, or ideally capture the wood gas.
The bigger the difference of temp between hot and cold the bigger the output. Try that starlight stuff to keep the cold cold and insulate the hot chamber to keep the hot.
@@sailaway8244 in this sense. When we lived in New Jersey during the winter the furnace would heat water that would flow through a radiators in different rooms. You could turn a valve to allow or cut off the flow of hot water to the individual radiators in each room. Would radiator heat be enough to make it work? Would something like this work over an oven like a Sterling engine works with heat?
@@peacepoet1947 no won't work on low temperature like radiators (max 80°C ) but has possibilities on any furnace producing 300°C flame temperature.....if devolped you might get lucky and produce enough electricity to power the furnace control circuit maybe even some kind of low power circulation pump making your heating system electrically independent once upto temperature🤔
Can a rocket stove be converted into a steam boiler with enough motive Force to successfully operate a steam jet vacuum for refrigerator Cooling? Thank you
Can you look up a theory about magnetic freezing, apparently if you have a magnetic flywheel, with either E type or C type magnets on the stator, Thank you love your videos 😊
Yeah I don't get why we just don't start using things with very great promise for dual functionality like a heatsink that operates as a thermoelectric generator you really don't see much of that nowadays
Usually the answer is that any thermoelectric generator causes a resistance in the thermal flow, so if your goal for a heatsink is to move as much heat as possible away from a chip or the likes, then you don't want anything impeding that flow of phonons.
You remind me of my stepdad. He was into watch repair, CB repair and installation, locksmith, and more than I can list. Always tinkering…🙏🏻🇺🇸
Amazing cough! Well executed and a great recovery!! Keep it real and content coming.. Great stuff!
Thank you Robert for this interesting video for us all to learn from Sir. Good day and peace too.

We don't have a "magnetic core", we have a magneto.
What'll really bake your noodle is... Why is it still hot after all this time?

Get Well, Rob!!! I voice sounds as though you have a cold, and the cough makes it seem more likely.
Or maybe a smokers cough.

could you use a stainless steel mesh for the conductor vs the solid wire for more performance?

The bigger the difference of temp between hot and cold the bigger the output. Try that starlight stuff to keep the cold cold and insulate the hot chamber to keep the hot.
That's ablative insulation, so it only works at temperatures where it actively degrades. At lesser tempertures, it's actually a terrible insulator.
Rob, are you going to try and make your own magnets using iron and nitrate salt?
We enjoy your videos. You don't look 100% in this video. Take good care of yourself. May you get well soon.
That's a lot of energy to make such a small amount of current.
Not if you consider the energy created a bye product of the primary function....ie heating or cooking

Was wondering if you could check into the liberty engine
Thanhs😊
I put a cheap £10 hydro generator (the guts) onto a stove fan and got 5v. So I can charge a powerbank when my stove is burning
Can you look up a theory about magnetic freezing, apparently if you have a magnetic flywheel, with either E type or C type magnets on the stator,
Thank you love your videos 😊
I have an idea based on what you've said here. I'll do a a few experiments my self and then let you know 😊
Could you use a metal vapor in an MHD?
He uses potassium from salts to improve results. Most generators that I have read about use Cesium as the seed material for their purposes.
!
Yes it is an electric universe.
🤦♂️
spray that again
