[DHAN HURLEY]

Hi Kirk,
I found your email in my Spam Folder so my last post was "out-of-sync",to say the least.
As they say in England :- "The proof is in the Pudding" and "It only takes one White Crow to prove that not all Crows are black".
My main focus has been to make TLUD's that are very inexpensive ( from scrap materials as far as possible ),as Low-Tech as possible,scalable,above all as efficient and healthy as achievable,as "elegant" as possible etc.

My latest version is for camping/mobility and is made from a 2nd Hand Ice Bucket,made from heavy gauge Stainless Steel ( double walled ).This sort of quality Stainless Steel ( Thermos Flask etc. ) is not easy to get 2nd hand,in Europe.It cost me Euro 3 in a Fleamarket.
The legs are made from thick iron Fence Wire ( Free ).The Grill top was bought in a shop sale for Euro 2.I drilled too many holes in the inner base so i bought some nuts and bolts ( new ) for Euro 2,to plug the excess.The outer insulation is Rockwool ( free ).
The total cost ( apart from my labour ) is Euro 7.In Europe,this is the price of approximately 15 large eggs.

Initially,i suppose,the Spiral Tubes could take a lot of,possibly, heat from the Gases.But overall the net effect might be positive.My main concern is to burn all the Carbon Monoxide ( CO ) and Nitrogen Oxides,thus enabling indoor use as well.
Having Spiral Secondary Air channels increases the complexity, though.Copper tubes, preferably with a flat cross-section,though round copper water pipes could be OK,surrounding the metal ( steel etc. ) combustion chamber is one way.Another method is to have the Combustion Chamber made from flat Cross-Section,high-temperature SteelTubes welded together ( Copper tends to flake at higher temperatures, e.g. burning charcoal ).OR :- A fairly thick high-temperature Steel Combustion Chamber with Spiral Air Channel groovescut into the outer surface, which is then covered with an insulator ( e.g. Rockwool,which is light ).Obviously, leaving the grooved Spiral Air Channels free and individually airtight.I like the latter design, being much easier and cheaper for me to accomplish.
Also better for mobile applications.

The air flow resistance, using Spiral Air Channels, is a concern for me plus the fact 
that a Cyclone Effect, if achieved with Venturi style exit jets, throws the colder air to the outside.This effect is used in industry to cool drills etc. (Ranque-Hilsch Effect Tube,"vortex tube")Thank you the comment about your experiments with adding a "swirl" to the gases, i will take this into account.
Again, though, i want to burn all the Carbon Monoxide ( CO ) and Nitrates

I disagree about the Thermo-Couple, radio etc.
There are different designs of standard Oil-Lights ( kerosene etc. ) with built-in 
Thermo-Couples and  Radios.The Russian Army had them in the 1940's, though they were bulky.The original LUFO Oil-Light made, as mentioned below, had a small radio and a 7 Volt 
(i can't remember the Amperage) Jack Plug built into  the base.It used the SEEBECK EFFECT.The Swiss friends who made the original design built in a radio for local weather forecasts for farmers,fishermen etc.
Theirs was a lot cheaper and for every one purchased they gave one away free to people in the "Third-World".Sadly, as explained below, they couldn't continue with it.

Lufo Hurricane Lantern with Radio ( AM and FM, Headphone socket and speaker ) from Petromax,€ 59,00.

The Conservation of Energy/Momentum Law still is valid,as far as i know,though others have become very tattered-at-the-edges,e.g. the 2nd Law of Thermodynamics,which is an oxymoron.

Using the "Joule Thief" circuit, which Self-Resonates typically at 50,000 Hz,i have lit a normal 100 Watt/230 Volt incandescent Light Bulb with a 1 1/2 Volt DC battery.The Joule Thief Circuit is also mentioned below.

A Supercapacitor is much quicker to charge and is very robust, a battery has certain advantages also.It would only be needed at the beginning,i think, to run a fan,if necessary.
What i like about some types of Supercapacitors is that they are easy to make yourself.

Yours Sincerely,
Dhan

I was studying your contribution to try to get the best idea of what you were saying, and other things crowded in.  It is always good to discuss biomass stoves with other experimenters of similar interest.  Your idea of spiraling tubes to increase the efficiency of preheating the secondary air interested me.  Several thoughts came to mind. 1--Preheating the secondary air uses heat from the wood gas, cooling it.  Mixing them back together will give the same temperature as if the air was not preheated.  The advantage to preheating the secondary air is that gasses are easier to mix when they are of similar temperature, and more difficult to mix when they are of differing temperatures.  That is a good reason to preheat the secondary air.1--The tubes may increase heat transfer, I don’t know.  It seems like it might work if the surface area between the air and wood gas is increased.  I have not done any tests about this so I cannot confirm.  1--It must be considered whether the tubes increase the flow resistance of the secondary air.  This would effect the power level (more draft available to the primary air), and also the ratio between the wood gas and secondary air (clean burning). 1--I have done considerable experimenting on using swirl to mix the gasses.  It does not help, and may hurt mixing by slinging the cooler, heavier air to the outer edge, like a centrifuge.  Mixing should be done before swirl is added, and the swirl should be designed to give more dwell time before the flame exits the stove.1--As you say, a forced air fan may not be necessary.  It may work as natural draft.  2—You will need more than a thermal couple, you will need a thermal pile to run a radio.  Check the power levels.4—The capacitor will need to be charged.  Hopefully it can hold enough energy to run the fan for the duration of the burn, 30 minutes to an hour+.  TEGs might be a better choice.5—Conservation of energy,  you cannot make 10 watts out of 5 watts.  When your volts go up, your amps go down, and watts remain the same (minus heat loss).  Power (watts) = (volts)(amps).  Kirk H.      Sent from Mail for Windows 10  From: peeters frans

Dear DHAN,     It looks like ,you have lots of dreams on principles ,But reality is mV for thermocouples and WATTS for ENERGY , with VOLT and low amps ,you light only dreams . So speak about a working realization…..    At 12 y my dream was making a bicycle light ,as strong as a cars light with an induction coil and car bulb ……I could make 12 V  out of 6 V, but the light was lower …!Why ? POWER is not transformed !!!         Copper/iron constantan is the thermocouple with the most millivolt.     Ni/ CrNi most used .      We think the burn-speed is most important for a TLUD STOVE  and see 3 zones 0-400° C/ 400-800 ° C/800°-1200° C .  In a SOUTH AFRICAN UNIV. You find Mr CRISPINS stove designs !

Onderwerp: [Stoves] Dhan Hurley..... TLUD enhancements.... Why aren't there any comments, except from what it seems is a Venture Capital Company?    Hi from Tübingen, S. Germany.  I sent the following email to  stoves at lists.bioenergylists.org . Why aren't there any comments,except from what it seems is a Venture Capital Company?   I have been experimenting with TLUD's.Using an insulating "jacket", i have been using ROCKWOOL with a wire mesh support, is an improvement. My next improvements will be :- 1)  SPIRAL outer Air-Channels ( TUBES ) for increased air pre-heating.Also for creating a VORTEX ( CYCLONE ) EFFECT at the combustion site,thus causing better combustion and a better suction of air into the TUBES.This would also enable a more compact and stable TLUD,good for camping etc. I will have to study some of my research into  VIKTOR SCHAUBERGER's VORTEX and IMPLOSION technology. There is a high probability, that with the correct adaptations, a FAN ASSISTED air up-draft won't be necessary. 2) A THERMOCOUPLE,which is very cheap to buy or very simple and easy to make yourself,even from readily available scrap materials, e.g. GRAPHITE and ALUMINIUM.This would provide more than the necessary power for a FAN, RADIO, TRANSMITTER,LIGHTS,  BATTERY CHARGER etc. 3)A SUPERCAPACITOR ( possibily ) instead of a BATTERY for powering the FAN when starting the stove,also for storing excess electric charge,which can be used later.A SUPERCAPACITOR is inexpensive and also very easy and simple to make yourself. 4)Using a "JOULE THIEF" electronic ( Self-Resonant ) circuit(s) with 2) and 3) above.This , again, is very inexpensive,simple and easy to make, even from scrap components.With this type of circuit you can increase the electric voltage output to whatever voltageyou want, within certain limits. Sincerely, Dhan Hurley                          *******************************************************  THE ONLY REPLY IS  FROM   kchisholm-inter at uniserve.com  :- Hi DhanI am very impressed with your work, and thinking!!I have an interesting proposal for you:1: I assign patent rights to you for an assemblage of ideas, relating to your work below, that could lead to a “world class patent”, in return for a 2% royalty on sales above $100,000.2: If you wish, I will do detailed design and construction of the system, and you would only pay for “out-of-pocket” costs that you approve beforehand. How’s that sound to you?Best wishes,  Kevin Chisholm, P. Eng, (Mech.)                                         *************************************************************  MY REPLY TO KEVIN CHISHOLM is below :-  Hi Kevin,I thank you very much indeed for your kind and generous offer.To me, it seems better for me to release this without a Patent.Anybody, including you,can create a business making these TLUD'swith the enhancements i have outlined below.I know that designs can be patented.  I am very open to donations for my present and future work.  I know some Swiss people who designed an Oil Light ( Kerosene, etc. ) with a Thermo-Couple built into the top, named LUFO.This was based on a Russian model from the Second World War.They patented the design, which had a radio and an electric power plug ( 7 volt ).The United Nations said that they were interested.All that happened is that they were "played-with" for 6 years.The person i knew had a debt of CHF 400,000, after that "run-around".  The excerpt below is from a very good site called  https://eagle-research.com/ , which makes and sells Brown's Gas machines, Kits, books etc.

https://eagle-research.com/mission/patent-free/
Patent Free
MAKE MONEY WITHOUT PATENTING!!!To continue inventing practical energy solutions, I make money immediately by selling books and kits, instead of spending thousands of dollars and years of time getting a patent. Investing the time and money into getting a patent does not give any guarantee you’ll make money. Selling books and product makes money immediately. Investing the time and money (that you would have spent acquiring a patent) into product development instead, will give you a much better chance of getting the product into the marketplace and give you money in your pocket. Not to say that patents aren’t an applicable tool in some situations, they just aren’t good for inventors in my situation. Nondisclosure agreements, trademarks and copyrights are inexpensive, fast, sufficient and reasonable protection.Several inventors have now seen what I’ve accomplished and are switching to my methods. CAN YOU FIGHT? A patent is only as good as your ability to fight for it. The patent office does not help you, except to provide a service to prove that you patented your device on a particular date. You fight your opponent in court at your own expense. Your chance of winning is not assured because there are many slippery ways around the patent laws.So you may have paid lots of money getting a patent, set your marketing back several years because of secrecy and STILL not be able to prevent competition. In fact, you spend even more money (and time) trying to defend the undefendable.Patents are an exceptionally bad idea for innovators with limited funds. Often Patents are ‘stolen’ and used without the innovators concent because the thief knows that the innovator does not have the money to take them to court.......................................................  continued    Again, thank you for the your interest and work.I hope we can continue developing these and other devices.Yours sincerely,Dhan Hurley DIASPORA COMMUNITY....
