Gas prices

Wormy, how does a hydrogyn car work? Talk about gas prices, I filled up my two crew trucks and their fuel cells for equipment with diesel- $902.00. How my employer will make a profit is beyond me. When they bid the job fuels was about 2.90 a gal, now diesel in the new England area is anywhere from 4.80 - 5.20 a gallon.

Our mechanic made a hydrogen generator out of a Mason jar for 2 different pickups that he owns. He increased his mileage by 20%.

Swamp it's a grease car. I could do that with my isuzu but it's a pain in the butt. You can use strraight vegitable oil. Thing is that you have to preheat the veggie oil to make it attomize in the cylinder correctly. Most have two tanks. One has a heater coil in it from the motor and the other is straight vegie oil. YOu have to start and stop on real diesel or it cokes up the injectors.

You can with little work create biodeisel out of vegie oil that runs about the same as diesel but it's a bit of a hassle as well, although if the price of fuel goes up too much more I'll be looking into it. Veggie oil plus about $0.75 per gallon gets you biodeisel. Won't run well in cold weather though you have to mix it with diesel below about 50 degrees.

Ethanol. Ethanol has a low vapor and flash point. Due to that it gets less power out of a gallon of gas. (less miles per gallon) It's only saving grace is that it burns more completly and is not a fossil fuel.

Hydrogen, This is produced in a couple different ways. When mixed with oxigen in the combustion chamber of the engine one of the byproducts is water. H20 A car can be converted to hydrogen in a similar manner to a car (or in most cases a forklift) is converted to burn Natural Gas. A car running on hydrogen will have a small drip or stream of water flowing out of the exhaust.

I am not sure about the Combustion ratio as it relates to mileage.

I'm posting this on (slow!) dial-up from the Isle of Man (TT races).

Here's something to ponder. A small plastic bottle (500ml) of diet coke costs twice as much as the same quantity of diesel or gasoline here! How does it compare in the U.S.?

The hydrogen cars can either run on it as a gas, or by fuel cell conversion to electricity. You can also build an electrolytic hydrogen/oxygen generator for your air intake to boost mileage, but I'm not convinced about that one!

You can also apparently boost fuel combustion efficiency by adding acetone to the fuel, but it can damage seals and dissolve paint!

You can also "cut" diesel with ordinary vegetable oil in a 50/50 ratio. It all depends on whether you are comfortable doing that with your engine. The guy who invented the Diesel engine designed it for vegetable oil in the first place. It was the petrochemical industry who bought his design and applied his name to a petrochemical diesel.

Proper bio-diesel is mixed with ethanol or something to settle the glycerine out of the fuel to make it flow better and burn cleaner.

All the hire companies here have signs on their vehicle saying that "use of bio-diesel will result in engine failure". So Biodeisel isn't exactly taking off here.

Was over in Bali in Indonesia a couple of weeks ago and a liter of fuel was 4500 Rupiah which is around US$0.45 and they were all saying that it is going up to 6000 Rupiah a liter or US$0.60. Other than that deisel in Australia is hovering around AU$1.75 a liter glad work pays for all mine....

I heard Biodiesel can hurt the new diesel engines I think..... The bigest issue is that the rubber has to be the right kind or it'll eat it up. Also fosil diesel leaves a varnish in the tanks and the fuel lines. The biofuel desolves that. A biofuel car or truck must typically carry an additional fuel filter for the first few tanks and most folks I've talked to carry one all of the time.

Clive the issue with 50/50 mix is the coking of the injectors. It's ok on a long haul or a now and then thing but if you do it all of the time it'll coke the injectors ... whats that you say? veggie oil burns at a higher flashpoint under compression. (Thats ok with a diesel) The issue is when you turn it off the residual veggie oil smokes and burns leaving a thick black soot. Eventually causing issues.

Bio diesel is cleaner and is a great effective cost saver. (If you want to go thru the trouble of doing it right.)

I've investigated it to the point that I am ready to go that route with my isuzu if fuel gets too expensive. I have a 1982 I-mark that currently gets close to 35 MPG. I should be able to boost it to 40 or better with a few more adjustments. I bumped it 3 MPG (I think) by putting in the proper thermostat last week I have to run thru a few more tanks of fuel before I can say that for sure.

Well if Your company will give away used transformer oil that stuff will burn in a diesel just fine. I dunno how it works with the new low sulphur deisels but it worked just fine with deisels 20 yrs ago. If ya wanna be sure cut it with the real thing. Also works great to kill unwanted weeds but The EPA probably would hate ya if they found out.

I erased my previous post about burning the animal fats etc. I had another conversation with my son. It's more like RWD described. The guy used vegetable cooking oils that he scrounged from restaurants. Told my son he had about 1500 dollars tied up in his filtering system and the car conversion etc.

He said in warm summer he could travel about 2500 miles before he had to fill up with diesel and in the winter about 1000 miles before getting diesel.

This was about 3 or 4 years ago and he got the cooking oil free from restaurants, but I bet he has to pay for it any more. Everyone is catching on to that game.

It was pretty continous he said as about the time he had 20 gallons strained for use, it was time to fill up the car and begin to filter a new batch. Said hardly any smoke and no bad smell.

A common quote from grease car owners is that when they get home "all they can think about is french fries" Evidently the smell permiates the car. I don't know if it's true or just a common joke.

I want to ask a question on this web site.

What do I do?? I'm not up on this.

[Split Bolt]

I have to relocating to a warmer climate. I know I can get a job with F.P.L. Are there any other options. I have worked too maney years in the freezing cold. My body can not take the cold much longer. My fingers don't have the cirulation they had when I was younger.

I have alot of years left to offer to the trade, if I can keep the fingers warm!!

At about 60 degrees my toes go numb. Spent too much time in the mountains in Colorado wyoming and Idaho. There are job openings noted on this site and you might find some openings on the NRECA site. They olny post co-op jobs though.

I was standing behind a Land Rover which was obviously running on used cooking oil. It started up and there was suddenly the delicious smell of fries. :)

I doubt it's likely to permeate the car any more than diesel would.

I just traded in my Pontiac G6 for an 08 Mercury Milan. Gets less mileage but is much nicer.

My good friend that farms down here in Bama is using biodisel using cooking oil. Its about the only way he can stay above water. If it doesnt rain again here soon the good looking corn crop might go downhill (it looks good so far).

Its 3.88 to 3.98 here in Bama, was just in South Carolina the past two days and it was around 3.87 I think.

Gas is 4.05 to 4.09 here!

[BigClive]

That vented hydrogen speeds at 45 miles (72 kilometers) per hour through the atmosphere on its way off the planet—one of only two gases, the other being helium, that escapes into space entirely because it is lighter than air. In fact, Strizki's quarter-inch thick propane tanks weigh less when filled with hydrogen than when depleted.

So does that mean when you convert water to hydrogen and vent part of it to space then there's no hydrogen to react back to water? So if everyone used these hydrogen converters we could end up starting to consume the planets water supply? That would be a bleak dry future.

When i worked in San Diego there was a company that was taking pure hydrogen mixing in oxygen to power a generator to the car battery through fusion. When the hyd and oxy atoms fused it gave of energy very similar to nuclear fusion just not to the same scale. the vapor that resulted was h3o or heavy water. the car averaged about 200 miles a gallon of hydrogen and achieved a top speed of 95. that was back in 2000. dont know what happened to the cars or the company
