Alternate Fuel for Diesel and Gasoline Engines - 100% off the Bowser

[evolvingape]

Hey Mr Goose,

Just as I finished telling myself to stop going off on these tangents, or at least if you do keep them to yourself, I had a thought...

Evaporation:

http://en.wikipedia.org/wiki/Evaporation

Key points:

Factors influencing the rate of evaporation

Concentration of the substance evaporating in the air

    If the air already has a high concentration of the substance evaporating, then the given substance will evaporate more slowly.

Concentration of other substances in the air

    If the air is already saturated with other substances, it can have a lower capacity for the substance evaporating.

Concentration of other substances in the liquid (impurities)

    If the liquid contains other substances, it will have a lower capacity for evaporation.

Flow rate of air

    This is in part related to the concentration points above. If fresh air is moving over the substance all the time, then the concentration of the substance in the air is less likely to go up with time, thus encouraging faster evaporation. This is the result of the boundary layer at the evaporation surface decreasing with flow velocity, decreasing the diffusion distance in the stagnant layer.

Inter-molecular forces

    The stronger the forces keeping the molecules together in the liquid state, the more energy one must get to escape. This is characterized by the enthalpy of vaporization.

Pressure

    Evaporation happens faster if there is less exertion on the surface keeping the molecules from launching themselves.

Surface area

    A substance that has a larger surface area will evaporate faster, as there are more surface molecules that are able to escape.

Temperature of the substance

    If the substance is hotter, then its molecules have a higher average kinetic energy, and evaporation will be faster.

Density

    The higher the density the slower a liquid evaporates.

Now stay with me here...

It is the few layers of water molecules at the top that evaporate, so, if we had a shallow flat container with a large upper surface area then more water could evaporate.

If we had an air input to the tank from just behind the air filter we could tap some atmosphere sucked in via the engine vacuum and divert it through the evaporator.

The outlet from the evaporator would go to the air intake nearest the engine.

This would mean that cold air would be constantly flowing over the surface of the evaporator water level. This air would also be non saturated due to it being atmospheric and at the outside humidity level.

If we were also to tap the waste engine heat from the radiator system we would add energy to the evaporator water, just making sure that it did not boil. 90 C might be good.

How much fuel saving would we get from this ?

Has this been tried before ?

If we combined this with a gas bubbler could we get over 50% fuel saving for ZERO energy cost ?

Whoa ...steady there big fella.  I love that you and Chet are thinkers...this is a good thing but too much of it can be counter productive.  Why doesnt anything much get accomplished at forums?  Because people SPECULATE and crunch numbers all day, running spice programs and discussing until the cows vomit why it MIGHT or might not work.  Don't get me wrong...I dont think this is what you are doing but you are at danger of being your own worst enemy.  Time is always money.

You know where I have made my best discoveries?  Thinking it out??  Nah!!!  The best dscoveries are made AFTER you have speculated on a theory for a SHORT period, then ROUGH out a plan of attack, THEN you head to the workbench and start on it.  THIS is where the likes of electricity, radium, explosives, and all the cool stuff was made...in the filthy workshop with your hands!!

Years ago I knew nothing about circuits and electronics and for the most part, whilst reading educates you, its no good if that material is flawed.  I started making circuits and ignoring all the rules and only THEN did I draw my schematic NOT the other way around. 

Don't get caught in the trap of thinking you have to get some design 100% right on paper first and then think you are going to go and manufacture only one.  Yes...it is true...Destiny loves preparation and therefore planning is a must but dont become bogged down my friend. 

You know Dyson the vacuum cleaner guy??  He had a great idea and was VERY clear about the design but it took him 5000 prototypes before it went to market.  If he had attempted to figure it on paper, we would be still waiting for the worlds best vaccuum cleaner.  Also - -KEEP IT SIMPLE.

Regarding your last post....all relevent points the answers to most of which I have. Saturation of air and vapor?  Yes...but you are now forgetting thigs like, what is the rate of demand on the fuel device?  Is there a vacuum?  Will the vacuum actually enhance evaporation (yes!!!).  You mentioned engine heat to enhance vapor off the water surface.  I can tell you this and cut your areas of time wasting - Raising the vapor temp (of water) will reduce its effectiveness within the engine combustion zone.  The colder the vapor and the smaller it is the better.  Dont forget...POLES OF BATTERY!

  Its really your journey though and discoveries you will only find when your hand touches metal in the workshop.  By all means write here what you want but lets try not have this thread become another Kapanadze debacle where 500 pages later they are still chasing their tail and have no idea what is up or down!!!  LOL

We started on page 1 KNOWING what will cut your fuel bill by 50% minimum....I suggested 2-3 things and we have since then built off that.  Now construct!!!

All the best

OK

Time to get you guys focussed again. 

In Thailand they are doing some fantastic things and running TRUCKS and cars on gasifiers.  Heres a YT video -

Here is a SIMPLE outline of a self sustained gasifier.

Now make it better.  This is only 1 possibility of alternate fuel!

Check out this baby, they have installed a 10KW normal fuel engine/generator with a Gasifier all on a pallet....this means you can shift the whole thing easily if you need to move from your home.  Still very small for 10KW!!!  Enough to power your small home.  See how TINY amount of fuel (syringe of diesel) make a HUGE amount of gas with the gasifier!!  The efficiency of gasifiers is through the roof.  In reality you could have this Gen out the back of your place (buried to dampen noise or great for rural) and with the amount of garbage we as humans produce, you would probably have plenty of fuel from your own waste.

Here is another guy that gives you a ste by step on how to make a tar free gasifier....the welds made me laugh but kudos to him for the job and doing it!

http://www.youtube.com/watch?v=f7M2DKX7kGA&feature=related

Here are what they call biochar gasifiers.  Campers use them.  Instead of burning timber quickly in open air that is SOOOO inefficient and gone in a second, you utilize a small amount of wood that combines with oxy and creates gas to focus heat like a stove.

Hey Goose,

That's all really great stuff. I can already see in my head a gasifier powered boundary layer turbine and the GECV is going to make that possible, I am confident of that.

A turbine generator is going to be much smaller than the 10kW ICE you linked too, and more efficient, so that's great news!

I have recently moved and for the first time have a garage to use as a workshop but I am not going to be building anything substantial for quite a while. This is very frustrating! I have both a laser cutting shop and a hydraulic shop a few minutes down the road but no money to get the parts and limited tooling. The universe is teasing me! So speculation and designs are all I can do at the moment.

I am going to do some thinking on how to miniaturise the reactor, the ones on youtube are way to big for my liking. I am very excited by this technology and I think I can do a lot with it given a little time to understand what I want to achieve.

One idea that has occurred to me is to convert a Kelly Kettle to a gasifier. I have the 3 Pint Stainless Steel version in the garage so that is something I can work on. Not quite sure the best way to do it yet though. Once I have a good conversion then the option to miniaturise that is there because the SS Kelly Kettle can be got in a smaller 1 Pint Size!

I know youre keen on recycling plastics and all but are you aware that you can only recycle SOME plastics with a gasifier?  Others have very corrosive elements in them that will catalyse inside the gasifier and corrode even stainless.

Just letting you know.
