Group: Ambassador Hero Member Posts: 4015	exploring the feasibility of a cheap thermal imaging tool for the community too many times in these forums experimenters are unaware of where the energy has gone [or is hiding] in their devices having the ability to watch the energy move thru the DUT in real time will be a huge tool for the Bench. could very easily test Thx1138 hypothesis on his experience with Wax and heat with a thermal imaging tool. as always in Peter's house [this forum], all will be open source. [will Mirror the build at Stefan's and elsewhere too we will open another thread for that project .[although all comments welcome here until we do] on another note ,I am not sure if ethanol has been added to fuels all over the world , but here in the US it has [bad for engines] Mark [slyder] shared this simple method for harvesting ethanol from our fuel, thereby tremendously increasing its quality here https://www.youtube.com/watch?v=RO1hsaxaMXo « Last Edit: 2017-01-09, 15:50:32 by Chet K »

Because it is water soluble it enables very easy water injection in order to enhance efficiency. And it burns very cleanly.

Group: Ambassador Hero Member Posts: 4015	muDped Here is a cheat sheet on ethanol http://www.fuel-testers.com/ethanol_problems_damage.html above info aside, the solvent attributes and incompatibility with older engines [which I happen to find more and more in my life these days] However , ultimately we all hope to get away from Carbon based Fuels thanks for your input. respectfully Chet

Group: Ambassador Hero Member Posts: 4015	Luc shared a quick reproduction of a test he did some time back with a Toroid 500 or so watts in almost 1500 amps out. https://www.youtube.com/watch?v=0QhKWbC22yY when I think of all the applications where this could be used !! I used to sell Oxygen assisted magnesium lances [Bell Labs] one application was to brutally remove seized pins in large equipment. A tool like this could do that Job like a gentlemen .[perhaps with a bit of Wax ?] « Last Edit: 2017-01-13, 22:52:11 by Chet K »

Group: Tinkerer Hero Member Posts: 3055	Quote from: Chet Here is a cheat sheet on ethanol Link to Ethanol Problems I agree. For engines which were not made for Alcohol there can be problems with deterioration of certain plastic/rubber areas of the fuel system. It is possible to "modify" those weak areas in older engines to resist the potential damaging effects of Ethanol. E85 and higher are the best choices for those who are attracted to Alcohol as an engine fuel. I'm attracted . Thanks for the link Chet. I should add that Acetone is a great additive for gasoline too. In fact, it seems to be cheaper than Denatured Ethanol at the hardware stores. --------------------------- For there is nothing hidden that will not be disclosed, and nothing concealed that will not be known or brought out into the open.

Group: Elite Experimentalist Hero Member Posts: 1399 ... .-.. .. -.. . .-.	I believe the thinking is also that when the ethanol is removed, it can be reused in hardier machinery. In effect not wasting it. The increased performance of running old engines with clean gasoline being the key area mind you. Could such a fuel work in some kind of welding torch ? Mix the ethanol and air like a mini adjustable carb for heat settings. How about using a simple compressor to both force the flame into a jet and give the air some pressure, making a turbo. Spin the mixture before exit, shaped like the barrel of a gun and slightly tapering like the exit of a ducted fan jet, for pin sharp precision welding. --------------------------- ʎɐqǝ from pɹɐoqʎǝʞ a ʎnq ɹǝʌǝu

Group: Professor Hero Member Posts: 3378	Quote from: muDped on 2017-01-09, 21:21:36 What could be bad about it? Lower energy density: 26.4MJ/kg vs. 46.4MJ/kg for gasoline (petrol). Higher ignition temperature than gasoline (petrol), leading to more piston erosion Chemical reactivity with aluminum when hot.

Higher ignition temperature than gasoline (petrol), leading to more piston erosion Chemical reactivity with aluminum when hot. Good points Verpies. Using an Alcohol fuel with up to 30% water content will increase the efficiency and cool the combustion temperature. Some say that the maximum water content should not exceed 20%. A lubricating oil formula which includes sufficient Castor Oil will protectively coat aluminum cylinder wall/piston surfaces to prevent chemical activity. Other protective coatings are possible as well. Engines which burn alcohol fuel should have a compression ration of at least 8.5:1; higher compression ratios enable better performance.

Hero Member Posts: 694	I have posted this video elsewhere however in its run and historical perception the use of alcohol as a fuel is discussed. It seems 'back in the day' Henry Ford designed his motors to run on either fuel. Although he had a preference for Alcohol as a fuel . Tests by various military interests at the time (according to the video) informs that the higher BTU value of Petrol is almost perfectly off set by the higher Compression ratio used for alcohol. It seems to me that the inference of this video is that if Hemp were allowed as an unfettered commercial crop and the machinery all ready available used to harvest, then the whole dynamic of energy would be radically altered world wide.-- All those options are all ready there and have been for many years, Its just not happening is it ? -- YET https://youtu.be/ySnk-f2ThpE https://youtu.be/YDRP7rv8ZXc As John Hutchinson's wife dryly observed when he was roughed up and arrested without charge and his property emptied of equipment - Its down to us (society at large) to alter something, seems we want to sit at the table and eat the pie but do not want to engage with the status quo, - t'was always thus ? Kindest regards D --------------------------- How many more to be .threatened, abused murdered, Their research in the hands of evil corporations intent on total control ? http://dnp.s3.amazonaws.com/b/b9/suppressed.pdf whilst we know little .. friends remember, In the kingdom of the blind, the one-eyed man is king.
