http://energy21.freeservers.com/bookrep.html  Want to know something else? I've found a way to convert gasoline into Propane! And it can never be marketed! All Engines from 1996 on up must run at an Air to Fuel Ratio of 14.7 Parts of Air to 1 Part of Fuel! My System goes 100 to 1 Air to Fuel Ratio, but it will never happen! You want something interesting to Research ? This is it!

Oil does rule all politics unfortunately. But can I suggest a simple alternative that we could all see as common sense? Use wind or wave power to generate electricity. Use this energy to split water into its prime components. Let oxygen into the air. Burn the Hydrogen in our cars and have water as the resulting by product. You could almost make this work in your back garden! We would only need lubricating oils then which could probably be created from vegetable sources!

People sort of do that now with jet packs.  It is only a short duration flight, but now wings are involve.  The first time I saw it used was in A James Bond movie (not a special affect but a real jet pack) and I have seen it used is several stadium events.  Instead of combustion used in the earlier versions, I believe the newer ones are fueled by hydrogen peroxide.\n\nThere are also hang gliders and parasails.

There are several ways. For example, burning it directly (mass incineration) or heating it withoug air so that it produces burnable gas (gasification) that can be the fuel to a turbine or reciprocating engine. You can also put it into a tank and let bacteria decompose it. This generates again gas that could be burnt.

That would be really cool, and they have been trying for years, but so far no success. Rocket planes, like the X-15 and Burt Rutan's Space Ship one, have flown outside the atmosphere, but only at speeds less than 5,000 miles per hour (less than Mach 7). Since orbital speed is 17,500 miles per hour (Mach 25), both these rocket planes immediately start falling back down to the atmosphere as soon as the rocket propellant runs out, which it does in just a few minutes.\n\nA jet powered craft could possibly achieve higher speeds, but unlike rockets, jets need to use air from the atmosphere to keep burning their fuel. While new experiments like the x-43 are testing very high speed jet engines, the problem of friction with the air remains. If you want to make it to orbit you need to get the full 17,500 miles per hour orbital speed, and at that speed the plane would melt from the same heating that the shuttle experiences during reentry. So the only way we know to get to space is to get above the atmosphere before the speed gets too fast, and no atmosphere means you need rockets that carry their own oxygen with them in huge tanks. It is very inefficient, but still the only way known to get to space.

This is what I found when I googled- freezing point of gasoline\n\nWell, gasoline should freeze if you get it cold enough! Gasoline does not consist of a single kind of molecule -- it contains several different hydrocarbons (molecules consisting of hydrogen and carbon atoms). In principle, if you cool a mixture like this slowly enough, it will form a collection of different types of frozen crystals, with the freezing of each type of crystal occurring over a (different) range of temperatures. In practice, often such mixtures don't form crystals at all but just gradually thicken and harden as they get colder, forming something like glass- hard but without the regular crystal that make a true solid so different from a liquid. In a glass, on a small scale the molecules are still jumbled up like in a liquid.\n\nThe problem of fuel getting gummy and solidifying is more of a worry with aviation fuel. High-flying airplanes fly through very cold air (every time I fly and they show the outside temperature, it's -80 F!). And one of the last things you want to happen to an airplane is for the fuel pipe to freeze up. People add stuff to aviation fuel to keep this from happening. Piston-powered propeller planes sometimes have isopropyl alcohol or other compounds added to prevent freezing.

Jet engines are very precisely calibrated and need a higher octane fuel (regular car fuel is about 83-97 octane, the efficiency at which it burns).

The jet engine has impellors inside it thatpull air into the engine through a channel called a venturi that tapers towards the center of the engine to a very small diameter.  The force of air through the venturi creates large amounts of heat from friction (like a diesel engine), and what happens is the jet fuel is introduced just before the smallest part of the venturi, causing it to combust and create the energy, or "thrust" you mentioned.  At the rear of the engine, there are dampers to restrict the output of the thrust, controlling the vehicle's speed.  The weight of the vehicle MUSt be less than the thrust that is put out by the engine, or the engine won't have enough power to move the vehicle.\n\nAs far as recycling, no idea.  Hoped the jet answer helps.

Jet engines operate by compressing incoming air, mixing the compressed air with fuel, burning the mixture, and exhausting it to generate thrust. This process becomes more difficult as the air density decreases at higher altitudes because the compression is less efficient. The air density eventually decreases so much that there is not sufficient compression to support combustion. When this occurs, the engine will "flame out" and the plane falls into a dive until density increases enough for the engine to be restarted.

To release the energy contained in fuels, you generally have to apply energy, or "ignite" the fuel. For a log of wood, for example, you would put a fire underneath it of paper or smaller wood. For a gasoline engine, you would use a spark plug and compression to start the release of the fuel's energy. In an atomic (hydrogen) bomb, the Manhattan project detonated many conventional explosives in a sphere around the nuclear fuel to super-compress and heat the Hydrogen, which then blew up.\n\nIn all the above reactions, heat energy contained in the chemical bonds of the fuel was released by the application of "starter" energy either in the form of heat or compression (or both).

I assume this question involves using common sugar (sucrose) are the fuel.\n\nThe answer would depend on how you are extracting the energy out of the sugar as well as just how large of a mass (rocket + ...) you want to move to the moon.\nYour question is far too vague (and meaningless) without A LOT more details.

The simplest way to make a jet engine is to make or buy a pulse jet, which is similar to a ram jet, except it has a small flap or valve that sets up directional gas flow.  It requires a starting air flow from a compressor to achieve sustained operation.  The way it works is the air flows through the valve down a tube where there is some kind of fuel atomization, the fuel is ignited initially with a spark plug, the ignited gas make their way out the exhaust end of the tube.  The momentum of the gas leaving the exhaust at a rapid rate creates a vacuum for the intake valve to start the whole process over again.  Very simple and there are jets often sold on ebay exactly for model jet planes. \n\nAs for a turbine jet engine the only thought that comes to mind is a highspeed pencil router used for detailed engraving and polishing, that runs off an aircompressor.  These run at or around 100,000 rpm and two could likely be welded together very carefully to make a mini tubine engine.  Although this idea seems plausable, there will be major hurdels to overcome. Primarily balance is going to be the biggest problem,  when you have something rotating at 10's of thousands of rpms any non semetrical craftmanship would like result in a very short operational life.  Also I doubt that the bearings on the exaust side will not seize after the heat and particulate is sustained for a period of time.  \n\nTo this day I have never seen a turbine jet engine as small as you are asking.\n\nCheck out the following website for a pulse jet design.

what the heck is a mentos rocket???  Do you put those little breath mint thingies inside a rocket and launch it?  That's weird.  Doesn't sound all that fun to me.\n\nWell, since I'm not sure what that is, I don't have any really good ideas.  \n\nBut here's some links for science fun\n\nhttp://www.funsci.com/texts/index_en.htm\n\nhttp://www.exploratorium.edu/science_explorer/

Several things.\n\nThe US Strategic Petroleum Reserve can be used for defense purposes.  In the event of a major war, you can be absolutely sure that personal travel will be severely curtailed, and as much of that oil will be used for military and defense industry purposes.  Comprised of 4 major oil fields, the SPR has a capacity of 1 billion barrels of oil.\n\nThe US Air Force is currently testing the use of synthetic jet fuel for use as an aviation fuel.   In Sept, a B-52 was flown with two of its eight jet engines equipped to burn a 50:50 blend of conventional jet fuel with synthetically produced jet fuel.\n\nThe US Army has been testing bio-fuels in diesel trucks.  Its use should be a non-issue.  The M1-A1 Abrams tank is powered by a turbine, which can burn a wide variety of fuels, including bio-fuel.\n\nThe US has coal reserves equal to 300 years of consumption at current rates.  Research is underway to efficienty develop synthetic fuels from coal, including in-situ conversion so the coal would not have to be mined.   The US also has huge quantities of oil-containing shale formations in the Rocky Mountains that can be mined and the oil extracted.
