I am trying to build a hover car with a vacuum engine. Can some tell me how to do it or where I can find how 2

Lots of variables here. Do you want one that will move with directional intent, or one that just floats?\n\nThe simplest method for making a "hovering" vehicle would be to take the vacuum engine, mount it onto a curved shield, with the curvature facing down. Make sure your shield is a very light material, balsa wood works, i suppose.\n\nIf you know where the vacuum's intake and output valves are, then it's easy. make sure you make a hole for the output, and secure the engine to the top of the shield. Turn on the engine, and watch the contraption float around aimlessly. It's basically how a air hockey table works, except in reverse.\n\nEDIT: one important detail. Are you trying to make a hover car strong enough to hold your weight? Because that would need one hell of an engine.

I don't know what your interests are, but one experiment that I have done in the past is building an electric motor.  It's easy and does not require a lot of equipment.  I'll include the equipment list below.  If you are interested, send me an email and I will send you a picture of the setup.  That would be easier than explaining it here.\nEquipment required:\n1)Small stable platform, like a wooden board (maybe like 6 inches long and 4 inches wide, and perhaps like 1/2 inch thick).  Maybe a piece of cardboard would work as well.\n2)Magnet (something like 1 inch by 1 inch and 1/2 inch thick)\n3)Copper wire with a small diameter (something you would be able to wrap around your fingers)\n4)6-Volt battery (might be called a lantern battery). The shape of the battery is rectangular and the battery terminals look like little springs at the top of the battery.\n5)Two paper clips\n6)Two thumb tacks

The string ties to the flipper on the mousetrap then wraps around one of the axles of your car (as in spin the wheels and wind the string around the axle as you're pulling back the trap) when the trap is released it'll unwind the string and power your car!     Can you tell I did this in physics class?\n\nHints - - try a length of elastic rather than string if you can (preferably about a quater inch wide or so)\n- - if you have no limitations on your design see if you're allowed to attach a "pull back & go" motor to the axle the string winds around (you'll win for sure with it!)\n- - Also using the back axle for power works better than front in most cases\n\nGOOD LUCK

Here is the "How Stuff Works" website devoted to cars. It has pictures of many of the mechanical systems of automobiles. Very informative.

you need a pressure vessel, ie gas tank, ISO tank etc. you have to force this in eithermachanically or by vacuum. (not hoover).

I'd suggest a rocket but there are always going to be some people who say it's pushing against the air so you'll spend time explaining how a rocket really works. How about something that actually does push on the air, a fan-propelled car? Easy to make, easy to run (but not if you have to make quantitative measurements) Fan pushes air backwards, air pushes fan and car forwards.

Because the air and all objects inside of the car are going the same speed as the car, try driving around a corner with a helium ballon. If you take a right corner the ballon will go to the right side of the car while you go to the left side.

a solid lift cam from a 1969 302 z28 engine, 202 intake valves, [preferably double hump heads, if you cant find these use 882 casting truck heads and have them cut for 2.02 intake valves.] a 700 double pumper holley, and most importantly,TIMING!!!! I MEAN BOTH IGNITION AND CAM TIMING. BUY A DOUBLE ROLLER TIMING SET AND RUN IT ON THE ADVANCED MARK. THEN BUY A RECURVE KIT FOR YOUR DISTRIBUTOR, RUN THE VACUUM LINE TO THE PORT ON THE CARB THAT SUCKS VACUUM ON ACCELERATION. WHEN YOU SET YOUR TIMING, REV THE ENGINE UP TO 3000 RPM AND HOLD IT THERE. ADVANCE THE TIMING UNTIL THE ENGINE BEGINS TO MISS OUT, THEN BACK THE TIMING OFF UNTIL IT RUNS SMOOTHLY AGAIN, AND TIGHTEN IT UP, THEN RE-HOOK YOUR VACUUM LINE TO THE CARB. DOING THIS WILL ENSURE YOU THAT THE CAM TIMING AND IGNITION TIMING ARE ON THE SAME AXIS, A MUST FOR STREET CAR PERFORMANCE, YOU WILL HAVE TO RUN PREMIUM FUEL, I RECOMMEND AMACO ULTIMATE, GOOD LUCK.

well, i cant really explain it, but you can use rubber band or a mousetrap to power the car. if u google "mousetrap car" or "rubber band powered car," you'll find diagrams and steps on how to make it.

you can attach a fan to the motor and then strap it on to the car. you can um attach something flexible to the motor, and put it on the car sideways, so that it pushes the car along. you can tie a string to the motor, and then run that string to its wheel and wrap it around the wheel (or the axle for the wheel) and then the string wraps around the motor. lotz of wayz. prob need more info though.

To start off, install a K&N air filter,or something of the same type. Next, put in a real good set of plugs{spark}like split fire,LGSpremium,Bosch.... Then ask around at the local parts place and see if they make a better chip for the Cav. I'm into V-Dubs so I don't know for sure if they do.Next make the exhaust as free flowing as you can and still be legal.  More air in, better burn, more air out makes any motor better.Most of this can be done fairly cheap too.  Have fun.

3 easy steps:\n - Build a car.\n - Power it with a rubber band.\n - Wind it up and let it run.\n\n\nGood Luck!

my dear, hope u r big enough to under stand my answer.\nok i appreciate ur idea to conserve all the mechanical energy produced in a car, but the problem is c if the battery can run a car which requires 100w power that means the power delivered by the battery is 100w now that power is exactly sufficient to run the car but if u want to recharge the battery again u need 100w of more power which will increase the load on the same battery which is to be recharged. which is absurd. so my dear it is practically IMPOSSIBLE to manufacture a car of ur kind. hope u got my answer if u dint understand u go through it once again then also if u face problems do not hesitate to write to me ok bye.

It's a pretty simple project. It's a car about the size of a matchbox car. But it's made out of lighter materials like wood or plastic. With a holes bored through the center in the shape of an "L" When the balloon is filled with air and released, the car moves forward by jet power from the escaping air. \n\nBasic directions: make or buy a small matchbox sized car made from plastic or wood. You can either drill two holes to form an "L" shaped passageway in the center of the car, or you can hollow out the car and glue small tubes inside it to make the "L" shaped passageway. Of course, you'll also have to put a small chimney with a lip on the top of the car; this holds the balloon in place. So, the balloon sits on top of the car. The jet exhaust points out the back.  Blow into the exhaust hole on the back of the car to blow up the balloon. Put your finger over the hole to keep the air in. Set car on the floor and release. As long as there are no leaks and the car's wheels spin freely, it should work fine. The lighter the car the faster it will go. The bigger the car, the more stable it will be. \n\nYou can try getting a pinewood derby kit from the local cub scout's supply store. However, you should replace the pine body with balsa wood. It's lighter. \nGood luck.
