WATER FUEL WATER FUEL WATER FUEL WATER FUELpossibly someone'll poke a critical hole in this, but it's seriously cool anyway.An edit;i'm not seriously suggesting that we all abandon fossil fuels as a source of energy, nor am i convinced that this system is genuine. There is, after all, no such thing as a free lunch, nor is there free energy.However, i DO think it's worth examining in a critical light, which is why i posted it here.

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?

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?

Hello I am looking for the most accessible, cheapest, hottest burning, most efficient fuel and maybe even environmentally friendly. And what would be already in my house(and NO I AM NOT MODIFYING MY NATURAL GAS PIPES).So post what you think. I usually burn fuels in those little pop can stoves, and in my pyrotechnics. Thats Not My Stove. But Its VERY similar.

I'm making a hydrogen motorbike that runs this kind of motor ===>http://www.ebay.com/itm/ME0709-Brush-Type-Permanent-Magnet-Motor-PMDC-24-72V-DC-Etek-R-19HP-pk-/250954809815?pt=LH_DefaultDomain_0&hash;=item3a6e1281d7 However, all i can find are " make your own HHO" fuel cells (which I'm pretty sure isn't what a fuel cell does but I might be wrong on that). Where can I find an actual hydrogen fuel cell that can power this motor plus lighting (and a few things like an arduino) for the motorcycle. Thanks a bunch!

A couple of questions: 1) Does anybody know where to get cheap platinum wire (or platinum coated wire) 2) Does AC work better than DC for electrolysis because neither of the poles will corrode. 3) fuel cells produce around 2 volts, right? 4) Is there a cheaper alternative than platinum for converting hydrogen (and does it need the oxygen?) into water and electricity?

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.)

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

I have a Toyota hilux that will not go over 80km(49Miles). I suspected it to be caused by lack of fuel supply so I replaced the diesel fuel filter and then removed the top of fuel tank to clean the pickup filter in the tank. Following this I blew the fuel lines that go from the tank to the filter near the engine with air and all the lines were clean with no sign of dirt. I then put it all back together and bled the fuel system before going for a test drive. After preforming the test it had not improved at all and still struggles to go faster than 80km. Wondering what would cause this after thoroughly cleaning fuel system? You can rev the engine all the way up to 3-4 thousand revs in neutral and its fine but under load it is very sluggish and wont preform. Could it be injector pump issues or something like that? Appreciate any help :)

Okay - so I recently read this article (Article) about this auto club - the hypermilers.My lady friend got sick and I had to take her home - we were a 30 minute highway drive away at the time. At the time, I was driving a 2006 Altima (31/24mpg for the mtx drive train).Applying some of the things mentioned in the aforementioned article, I got a consistent 41.5mpg averaging 50mph and when I parked at home after some city driving and a lot of stop signs - the meter read 40.2mpg! For about 5 minutes on the highway, I was getting 43.4mpg.Impossible you say? Here's a picture off the dash from last night ;) Mind you, this was with an atx gear box! So those EPA estimates should be lower than what I posted above. Now that's damn near Prius territory for the average everyday stop/go driver with a 2.5L engine :PAt no time did I draft anyone or shut off the engine while en route. AND, I didn't take anything out of the car. There's a road kit, some umbrellas and a case of water bottles :PSo does anyone know where I can buy a meter to measure my fuel economy like this? I found Scangauge but the $170 cost comes with a bit of sticker shock :P Like the article said -- it turns into a game always trying to beat your last high score :P

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.

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

For my birthday I asked for (and got) the book Fuel Cell Projects for the Evil Genius. At first I liked it a lot. It had good information, and some really cool looking projects.What I started to realize though is that many of the instructions for many of the projects just say to go out and buy something from the author's store. The entire instruction for the Desktop Hydrogen storage unit was 2 pictures and a link to his store. This really made me sad. I bought this book because I don't really have the budget to go out and buy a lot of premade stuff.Has anyone else bought this book, or does anyone else have any thoughts about this?

Hello, Please read through this thoroughly. I'm planning on buying a petrol generator and running it on propane however I wish to still be able to use petrol without too much hassle, I have made some plans on which components need to go where and what I need to buy. I have a fairly good understanding of how the, engine, carb, fuel tank, ect works. I was just wondering if it would be safe and if it could cause any problems to the generator or even me (explosion hazard). I have uploaded a picture to demonstrate what I mean press the I at the top left hand corner to make the photo bigger :) This is a 4 stroke engine so it has a reservoir of oil built in to lubricate all the components as necessary to keep the engine running Things I need to know. Will it damage the engine not being lubricated and cooled by petrol. Could the propane tank/carb/engine or anything explode? - is it likely Are there any other risks I have overlooked. your opinion of the design if you think it will work and any tips on making it better. Stuff I'm using: - most will be bought on eBay Generator - 1kw not 100% decided which one I'm getting. Regulator - 37mb 8mm hose connector 1kg/hour. I understand it is 8mm however I will stretch a hose over it no problem T piece - 6mm barbed T piece for fuel lines Fuel On Off valve - Barbed 6mm hose connector 6mm unleaded fuel line 2 meter - hose from fuel tank to on off valve to t piece to engine 6mm orange propane gas line from T piece to 1 way valve, regulator, propane tank - although it is a 8mm regulator it will stretch on to the fitting nicely.

Will I be able to use this barrel as my compost barrel and be safe from using the compost in my garden, lawn, flower, etc?

Do you think the people who designed this had some sort of irony-deflecting helmets?Hummer will offer E85-compatible flexfuel engines on both the H2 and H2 SUT starting for model year 2009, and by 2010, all Hummer models will be flexfuel-compatible. We'd have to put a few hundred miles on a test rig to say for certain, but based on our experiences with (a) Hummers and (b) ethanol rigs, we'd wager that the 2009 Hummer H2 E85 may well deliver the absolute worst fuel economy of any vehicle based off a light-duty truck chassis sold in the US in the last 20 years. Our guess: 11 mpg highway, 8 city. Going downhill. With a tailwind.As a special added bonus, E85 Hummer owners will be doing their part to jack up their monthly grocery bills---and everyone else's too--as increased demand for E85 has caused a serious disruption in a major component of America's food supply, which in turn has adversely affected the price of meat and dairy products, sodas and sweets, breads and breakfast cereals, baby formula, jellies and jams, salad dressings, and yes, even our beloved corn dogs. Now you've really ticked us off! But hey, it's clean and it's green. When you put it that way, $7.99 for a bag of tortilla chips doesn't sound so bad after all, now does it?via Fourwheeler

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 !

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.
