I am fully versed and practiced in column distilation.
I am designing a top-secret device. However, i need to know whether i can use propane as its fuel source. i need enough thrust to lift a 120-pound weight (54.5 kg) about 3-5 in (roughly 6-11 cm) off the ground for a long time, until i turn it off or run out of fuel. I am wondering if propane is the best option for somebody who can not afford to spend a lot of money on expensive fuels. Also, can it work without any extra propellants, just air?

i burnt wax by keeping it on a spoon on a flame.... after some time it caught fire. then when i turned th spoon upside down large flames were there as if flame shower. so is it a good fuel?
Hello. I am new to this site. I've always had an interest in Model Rocketry and have built a lot of small scale rockets and launched them with store bought engines over the years. I've always wanted to build larger scale rockets and learn how to make my own solid propellant to fuel them but never knew how to get started. Any advice?

There is a big movement going on about making your car get better gas mileage with different kits and fuel additives. I read about Ethos over atIncrease Gas Mileage Increase Gas Mileage. Is it really possible to increase your gas mileage with simple solutions? Maybe the oil industry really is trying to keep a tight lid on this whole industry....

If hydrogen and oxygen are burned together they produce water. You need a lot of hydrogen and oxygen to make a very small amount of water. If when burning those two gases together produces water, which takes up much less space, how can it possibly propel a rocket into space. You need expanding gases to force something forward. Hydrogen and oxygen when burned together IMPLODE they do not EXPLODE ! The two gases contract into a liquid they do not expand like conventional combustion of solid fuel !

When I bought my Mini, I could not squeeze £20 into the tank. Now a re-fill costs me £28-£30. There is a petition waiting to be signed by at least 100,000 people in an effort to lower fuel prices. It currently has 88,000+ signatures. I've signed and ask you to sign to get this subject debated in parliament and hopefully get fuel prices down, the prices won't come down unless we try, and try hard to get the debate going. Please sign it now at this link. News: since posting this topic, the number of signatures has risen by over a thousand. (Sorry, non-UK members, this is a UK-only petition, but if you know any Brits with a vested interest in fuel prices (ie, all of them), then please pass this on to them.)

Hi all can a diesel run on 2stroke fuel mix if the 2stroke oil was added to the petrol in heavy enough quantities so that 1. It off set the octane rating of the petrol so that it acted like diesel? 2. It was blended with diesel to supplement the mix? The reason I ask is that there is a lot of mistakes made at the fuel pump with people putting fuel in diesel and I was wondering if the petrol was know, that a measured amount of 2stroke oil was added that this would solve the problem, rather than the expensive issue of towing, draining and repairs? I have had this experience and drained most of the petrol and then added motor oil to the new diesel to help lubricate and no dramas. Positive comments please.

I was just browsing the information on e-cigarettes when the thought hit me. Here we have a small electronically controlled atomizer, what better use can we use it for. One of the first ideas came up was to use it as a fuel injector for small model airplanes. Anyone have any ideas or remarks? Btw theres plenty of companies wanting to give them away because it creates a "bond" where you need to buy the refills from them. Little do they know that I like to re purpose "free" things

Mark Armstrong's Alternative Fuel PhilosophyIf you don't like the vehicle or the fuel it drinks, make some of your ownIt's on every billboard, bumpersticker and street placard: Let's Green This City! Urban Streets Greening Project! Each election ushers in new green initiatives, task forces, and elementary school awareness fairs. Another press conference, another earthy guy in an organic-cotton denim shirt and red Crocs stands in front of City Hall pointing an accusatory finger at the uninspired plebes who won't join us, who won't dare follow San Francisco on the righteous path toward a greener tomorrow.Meanwhile, eco-conscious drivers can't get a drop of biodiesel in city limits, while Berkeley, Santa Cruz, Santa Rosa and other surrounding cities offer it at public pumps. (In June 2007, city authorities closed the San Francisco Biodiesel Co-op, for - get this - having too many members.) Not one public pump in San Francisco sells ethanol. The few electric car-charging stations that remain are defunct, rundown or hidden in corners of musty garages, forgotten relics of a well-intentioned but poorly executed past. Our performance so far in fostering alternative fuels - the keystone of the green movement - is not just ironic; it's shameful."You know the easiest job in the world is to be a cynic," says Mark Armstrong, lifting his head from the hood of an electric-powered 1980 Plymouth Horizon. "In order to be successful you have to do absolutely nothing." Armstrong brushes his oily hands against his oily jeans and walks to the back of a cavernous concrete-floored warehouse, through a maze of Frankensteinian inventions: an electrolyzer that splits hydrogen and oxygen fuel, junky gas cars that run on golf-cart batteries, gutted petrol engines that gulp alcohol and a Mercedes motor that bakes bread and spits out edible olive oil."What I'm trying to do here is teach people to quit complaining about what they can't get," he adds, pushing his 6-foot-2-inch frame beneath a gutted 1976 Porsche 914 that he and his students are converting to a hydrolic hybrid. "I say if we really want alternative fuel vehicles, let's get off the couch and start making them."Step 1: Build a Carmore

Ethanol is under fire again: At first blush, biofuels such as corn ethanol and soybean diesel seem like they would be great from the standpoint of global warming. The crops soak up carbon dioxide from the atmosphere as they grow, and that balances out the carbon dioxide they produce when they're burned. But until now, nobody has fully analyzed all the ripple effects of this industry. And Tim Searchinger, a visiting scholar at Princeton University, says those effects turn out to be huge. "The simplest explanation is that when we divert our corn or soybeans to fuel, if people around the world are going to continue to eat the same amount that they're already eating, you have to replace that food somewhere else," Searchinger says.Searchinger and his colleagues looked globally to figure out where the new cropland is coming from, as American farmers produce fuel crops where they used to grow food. The answer is that biofuel production here is driving agriculture to expand in other parts of the world."That's done in a significant part by burning down forests, plowing up grasslands. That releases a great deal of carbon dioxide," Searchinger says.In fact, Searchinger's group's study, published online by Science magazine, shows those actions end up releasing huge amounts of carbon dioxide. The study finds that over a 30-year span, biofuels end up contributing twice as much carbon dioxide to the air as that amount of gasoline would, when you add in the global effects.

Wow! Prices are on the rise, and RAPIDLY! $4.00 A gallon gas, here in the good ole U.S. of A. Have you been to the grocery store lately? I haven't, my heart cant stand the strain. When my wife tells me grocery-price horror stories, I have to make her stop so I can take my blood-pressure meds. I've always been frugal, maybe even tightfisted. I'd just like to build up something I'd be proud to leave my kids and grandkids some day. (Note to Skunkson: No grandkids for at least 10 years!) Sacrificing comfort in the interest of a better future is a noble cause. But the current economy is squeezin' this poor boy to death! I am: A) Trying to get a job closer to home. B) Parking the SUV. C) Driving the crappy, egg-shell, crackerbox economy car (and the Harley to soothe my male ego). D) Adjusting the thermostat. E) Doing more with the garden and the chickens. F) Rationing my beloved Coca-Cola. So what are you doing to cope with the raising cost of getting by? Real suggestions would be best, but humour wouldn't hurt, as the only thing I've laughed/cried at lately is my plummeting bank account.

I have a full knowledge of how petrol and diesel engines work so I know that it is far easier to get a liquid fuel into the combustion space than it would be a solid fuel. However this does not mean that that it would be impossible to introduce a solid chemical fuel broken down into a light powder. The problems would be to identify a suitable fuel and its costs. It would obviously be necessary to dispose of combustion by-products with minimal polluting effects. Does anyone have thoughts on this or do you think its a non starter? I would appreciate any thoughts. Bean

My truck, over the last few months, had developed a lovely little penchant for not wanting to restart once warmed up. This wasn't to bad as long as I didn't plan on being anywhere less than 3 hours, and kept my wife from sending me to the store. But with summer here and wanting to be able to run off and go fishing I decided to fix it. After doing some diagnostics I think the most likely culprit was a fuel pump that was sticking as it heated up, and I thought this info might help anyone needing to replace theirs. Day one, we'll spend this day dropping the fuel tank. Those repair manuals are really helpful, just slide a jack under the tank, unbolt the straps, drop the tank, disconnect the fuel lines and you're done. The reality is just a little different. Firstly the entire time you're working under your car a gently rain of road grime consisting of grease, dirt and decayed road kill will be falling into your eyes, ears and mouth. Second, there's a lot more lines going to the fuel tank than the manuals say, after sweating and swearing over trying to remove the spring clips the best option is just to cut any rubber lines since after 10 years they're all rotten anyways. Now struggle blindly to maneuver the fuel line disconnect tool into position by feel, while pushing the tool into the connection shove the fuel line in the direction of the tool while simultaneously stabilizing the fuel tank with your head. Once all the lines are cut or disconnected lower the tank using a jack, a couple of coffee cans and a bunch of short pieces of 2x4 and drag out from under the vehicle. Unscrew the fuel pump assembly and remove from tank, then detach fuel pump from fuel pump assembly. you are now done for day one since your wife has the other car. Day two, taking a section of each of the lines you cut, along with your old fuel pump, visit an autoparts store, hand the lines to the clerk and ask him for 3 feet of each size, now marvel in wonder as he LOSES the pieces you gave him between you and the back of the store. Smile nicely as he tries to explain what happened and then say "Umm No I don't need anything else" and leave. Go to second auto parts store where they will try to sell you, first, the wrong pump, and then, when they finally admit it won't work, they try to sell you the entire fuel pump assembly, say "Let me think about it". Go to dealer, laugh hysterically and vociferously ejaculate "Oh Heck, No!" when they say the pump is $439.00 and will be in Monday. Lastly drive to the final remaining autoparts store and say "Please tell me you have a fuel pump like this one" and rejoice when the guy say "Sure, you need the Bosch with the adapter socket, I can have it here by three". Weep with joy, go home and wait until three. Day three, the true horror is that we now reverse the steps taken on day one and there is no way to test if everything works until the last bolt is tightened, however day three began with a stuffed up head and severe vertigo caused by allergies, apply medication and go back to bed for several hours until you can stand without puking. When well enough, reverse the steps of day one. Fortuitously the majority of the road grime will have fallen on you already and this time it will be as refreshing as a summer's shower. Add two gallons to clean gasoline and start the vehicle, when the vehicle fails to start remember that you disconnected the battery. Remedy that and marvel when your vehicle starts, but the joy will be short lived when you remember that, oh yeah, it would start before. So now, hold out hope that it won't have the hot start problem anymore, but you'll never know if it will happen again, unless it happens again.

03.05.09 -- In all the futuristic visions of robotic technology, there's always one buzzkill that brings them back to reality: the power source. How do you keep robots rolling smoothly? The Defense Advanced Research Projects Agency (DARPA) is funding the development of a robot that may have the answer to this.According to company president Dr. Robert Finkelstein, Robotic Technology, Inc. of Potomac, Md., is developing the Energetically Autonomous Tactical Robot (EATR), an unmanned vehicle robot designed to collect biomass leaves, wood, grass, anything combustible and use it through burning to fuel itself. "The idea is to have a robotic ground vehicle that can go out on long-range, long-endurance missions without human intervention," says Finkelstein, describing it as the ground equivalent of long-range unmanned air vehicles. The EATR will be able to retrieve items of interest as well, or act as a weapons platform....In addition to its military applications, Finkelstein also envisions other applications, such as border patrol or agricultural work.here is the link to the full article

I saw a program on TV about the use of methane gas in rural Chinese homes. They had a digester under the floor of the pig pen which was attached to the house ? The pen was cleaned each day and the waste was washed down a drain which was the waste holder for the digester. The whole house was heated by methane gas and all the lighting and cooking as well. It sure looked like a good idea for someone off-grid . The way fuel prices are going, it my be a pretty good idea for people who are held hostage by the fuel providers. I am of the opinion that there are a lot of very smart people on this site, so if anyone can think of a way to do this, let's hear from you.

The first manned, hydrogen-powered plane has been successfully tested in the skies above Spain, its makers say.The small, propeller-driven craft, developed by aviation giant Boeing, made three short flights at an airfield south of Madrid, the company said.It was powered by hydrogen fuel cells, which produce only heat and water as exhaust products.The tests could pave the way for a new generation of greener aircraft, the company said.Boeing's chief technology officer John Tracy said the flights were "a historical technological success" and "full of promises for a greener future".Small futureThree test flights of the two-seater aircraft took place in February and March at an airfield at Ocana, south of Madrid. The plane was modified to include a hybrid battery and fuel cell system used to power an electric motor coupled to a conventional propeller.

Planes use a massive amount of fuel to move passengers and cargo around the world. A new design from an MIT team could cut this fuel usage by 70%. This is great news and would make flights cheaper and pump out a lot less carbon. The bad news is that air traffic is expected to double in the next 30 years and the earliest these designs would be in the air is 2035. MIT designed their D-series as a 180 passenger aircraft meant to replace the domestic 737 market. Conventional airplanes utilize a single fuselage design, while the D-series uses two partial tubular shapes placed beside each other — which accounts for the bubble nickname. The plane utilizes a host of technological advances to decrease its fuel consumption. It has thinner longer wings and a smaller tail and engine placement at the rear of the plane instead of on the wings. All of these features account for part of the reduction in fuel usage.
