Does water-fuel technology really work?

There are said to be a number of ways to substitute water for every sort of combustible fuels currently used in engines today, such that it is possible to run cars on water instead of gasoline or diesel oil.

There is nothing exotic about electrolyzing water, and using the Hydrogen and Oxygen liberated to power an internal combustion engine. Minor changes to the spark plug system would be indicated.
However. some inventors claim to have gone (a lot of) steps further, and say that, contrary to what we all learned in school, they can extract the Hydrogen and Oxygen from Water using less energy than their re-combustion produces. That is, their water-for-fuel system yields more energy than it requires to fuel it. That is, that all the scientific laws that say this is impossible are lies, or misapplied somehow.

A hose busted in my engine.It is now leaking rusty water/oil.im not really sure.when i put it in drive and pre?

ss the gas it wont go.When i put it in neutral it drives. Im just trying to get an idea what this could be.Im leaving for vacation in less than 24 hours on a 6 hour drive! Im a nervous wreck! can anyone help?
ok so let me give more info…1999 dodge caravan..not sure what hose but i knew it was a hose cuz the engine was kinda splattered with wetness i guess..engine was smoking and car jerked. it kind of hesitated when i hit the gas. finally it started to drive but again with hesitation…got it to the gas sation and opened the hood to see i guess a wetness that looked like an explosion of fluid then under the van it was leaking too,,it looked as though it could have been rusty water on the ground..is this gunna be expensive??

2000 Ford Focus starts to idle really bad and then cuts off when I come to a stop.?

I have a 2000 Ford Focus and I am having problems with it……every time I come to a complete stop like at a stop sign or red light or something it starts to idle really bad then cuts off and the engine lights come on but when i crank it back up it drives fine and the engine light goes off. I took to a mechanic and the timing belt and water pump was replaced, fuel filter replaced, and new wires, had the oil changed and it is STILL DOING THE SAME THING!!!! I am so aggrevated. My uncle who is sort of a shade tree mechanic, mainly works on way way older cars, but has his own shop worked on it for three weeks and it completely has him stomped. I took it to autozone that ran a diagnostic on it and said I needed to add some Octane boost to the gas tank and upgrade for a while to a better fuel…tried that didnt work either and they also said something about an Oxygen Sensor…(O-2 plug/sensor) I have not tried the O-2 yet but I hate to waste more money if that isnt the problem…i’m just trying to save money by not going to dealer any one has any ideas?

Did I really burn this much fuel??

Me and my girlfriend went to Ft Myers Fl. for a 3 day vacation. On one of the days we rented a boat to go cruising around the water for the day. The place wanted 200 dollars for a full day or 150 for a half day plus you pay for the fuel you burn. We are on a tight budget so I got the guy to give us a full day at the price of a half days rate. The tank is full when you leave and they fill it up when you get back and you pay for that. The boat was a 17 foot pontoon boat with a yamaha 70hp motor. We were in the boat from 11am to about 4:30pm. About 5 1/2 hours. In that time we stopped twice for about 20 minutes and 45 minutes. So id say the engine was on for about 4 total hours. In that time we were full throttle about 75% of the time. Had a few no wake zones to go through. We get back and he says we burned 29 gallons of fuel!! At 5 bucks a gallon! You do the math.. Not expecting this at the least!! Did we get ripped off? Was the tank not full when we left? I didnt check..

Winter is upon some of us. Thus, which is it: can gas lines really freeze or not? I’ve heard both sides…

I want to know so that I’m not wasting my money on HEET. I’ve heard people say that gas’ freezing point is like negative 70 degrees Fahrenheit or something unbelievably low. I do use HEET during the summer when it rained all night or in the morning to since I knew water somehow got into the tank because of the way the engine would run until I drove for a few miles until it became normal again. This also happened when I would first start my truck up in the afternoon on really really humid days.

Does this car repair really take that long?

My boyfriend said he had a big car repair to do this weekend that I know he had been planning on for weeks. His dad owns a garage and he does his own repairs. He said something I think about a fuel pump, water pump, spark plugs, and some filters. It took him a few hours friday evening, all day saturday, and a few hours sunday. Does this kinda stuff really take this long?
he has a mid 90′s bmw. not sure of the model

I just filled my tank and added a bottle of iso heet is it really needed in winter time?

I let my car sit for 1 day without starting it and it fired right up but struggled and died then i fired it up again and it was struggling but it stayed running and eventually it started to idle normally does this sound like the fuel lines were frozen? I added a bottle of iso heet in my near full tank is that ok? iso heet says it Absorbs 5 times more water than regular gas-line antifreeze. Cleans fuel injectors and carburetors. Designed for year round use in all 2-cycle and 4-cycle gas & diesel engines. Removes water from fuel system. Prevents rust and corrosion is this true?

How do I sell my car? The KBB pricing doesn’t really fit it’s condition.?

Okay, first off, my car is not in good mechanical shape. It’s a 1987 Toyota Camry with a nearly-dead transmission. It still drives, but is not long for this world.

It has some tears in the seats, but has the engine from a 1988 Celica.
It needs a repaint, but it has an external speaker mounted on the bumper, connected to the radio (don’t even ask, ‘k?)
It’s been in a few collisions but repaired.
It’s got a CB radio inside with the antenna welded to the back of the car.

New brakes, alternator, radiator, belts, shocks, battery, fuel pump, water pump, filters.
