Possible to Double MPG With Fuel Additives?

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....

Solid 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?

UK Fuel Price Petition

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.)

E-Cigarette to fuel injector

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

Make Your Own Fuel from Wine

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

Study: Ethanol Worse for Climate Than Gasoline

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.

Rising Prices! What are you doing to cope?

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.

How to replace your cars fuel pump in three easy days

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.

Unmanned vehicular robot fuels itself

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

Hydrogen-powered plane carries human crew for first time.

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. Hydrogen-powered planes have been flown before, but never with a human pilot onboard.BBC Story

MIT team designs plane that uses 70% less fuel

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.

Car Runs on Home-Brew Hydrogen

BBC News are running an item about a car running on home-produced hydrogen.UK company ITM Power has produced a plastic film they claim is suitable for home electrolysis of water to produce hydrogen. The hydrogen (they say) can be used in the home, to be burned for cooking or heating, or to power a car (they are simply burning it, but it could supply a hydrogen fuel cell).As we have mentioned elsewhere on this site, current sources of hydrogen are not "green" (95% of current H2 supplies are manufactured from fossil fuels), but ITM say that their system is green because you aren't stopping at a filling station, you're generating your own hydrogen from the energy resource of your choice (maybe your own solar cells or wind turbine).Others, however, have questioned the wisdom of storing tanks of hydrogen at home.Whatever the application, if this new material is all that they claim, it could be a major step towards a true hydrogen society.BBC StoryITM Power

HHO generator improves fuel efficiency of petrol engine!

Reproduced verbatim from The Fortean Times issue 249, republishing from FT35JUNE 1979On the 15th a demonstration of a "revolutionary" energy device took place at an undisclosed location in the UK. Iowerth Thomas, 58 a Welsh inventor, hoped to interest both government energy officials and an Arab consortium. Mr Thomas had been experimenting since 1936 with ways to make petrol engines burn more efficiently. His "bolt-on" device promised between 25 and 40 per cent efficiency using "the electrolysis of tap water", plus a cleaner exhaust. The government scientists' response - that it was impossible - spurred Mr Thomas to demonstrate it for them. He reported to the motoring correspondent of the Daily Telegraph that his stationary engine ran for 112 seconds with his device and for 77 seconds on the same amount of petrol without it. The usual objection to electrolytic systems is that the energy needed to run them is greater than that produced. With some sarcasm, New Scientist sniffed that the device needed to be much smaller than the room-size contraption Jones used. What really stoked their scorn was Thomas's reply when asked how it worked: "It's beyond me," he said. That was the last we heard of him and his promising device.How has this technology improved in the last 30 years?L

I volunteer to gather eyewitness info on water into hydrogen.

I'm a beginning engineering student and my dad is also an engineer. He is pretty skeptical and he recently told me of someone he knows who is using electrolysis to get better gas mileage in a Toyota pickup. I'm not sure, but it seems he is using secondary voltage to power the split and then burning it. He claims 60 mpg. If you guys would like to give me a series of questions/tests, I would love to go to my hometown and ask/perform them, then report back. Any takers?

Very Small Scale Power Generation in Developing World

Hello Everyone, I volunteer for a non-profit which distributes solar lanterns primarily to students as well as people who are in need of the lights.  Things have been going well but a lot of people have inquired about us providing access to a higher powered version for various reasons and we've noticed that some households go back to their old ways when the lanterns don't receive enough sun during the day.  Temporarily we are solving the problem by having local entrepreneurs charge batteries for the families for a small fee but we feel that this should not be a permanent solution. It's not the price that's the issue it's that sometimes the people have to walk for a number of kilometers to get to the nearest charging station or have to cross dangerous terrain (I have personally experienced this). Over the last 3 years we have helped over 5000 families by giving them solar lights so we would like to modify all those units to have more stable energy generation. Our current version has an output of 5 watts. We are looking to buy or build a unit which produces a maximum 8wh an hour until the fuel source runs out or something that can generate in a more slower rate such as 40wh in 16 hours so we can let it run overnight and have the power stored in a battery. We are primarily a donation driven group so something with low cost and maintenance would be really great.  We highly subsidize the price to a large percentage of the households but we also provide them free for the lowest 10% of households who can't even afford the lowered price. I personally think that something which can generate electricity from hydrocarbons due to their high energy density and easy access would be ideal but I'm not an engineer so what do I know.  I'm not sure if this helps in any way but a number of years ago we transitioned a large number of houses from wood fired stoves to gas and as all the families that we help actually have access to gas I was wondering if any good technology exists where electricity can be generated by gas that can meet the low cost and maintenance criteria.  I've looked into thermoelectric generators but they are really inefficient and people will be wasting money to heat their house in a country where average temperatures are in the 30'sC I also see a future issue regarding battery degradation as we use small lead acid batteries and while thinking of a way to solve this I came up with the following idea and is one of the reasons that I'm posting on instructables. What if a pedal powered flywheel generator was built with a 200W generating capacity and 40Wh worth of 'storage'.  When you pedal you will spin up the flywheel and it will store the energy until you need the electricity again and we could also wire up the solar panel that we already use to spin up the flywheel.  So when the sun is out the panel is used and on rainy days and during the night you pedal for a couple of minutes for one hour of lights.  If the flywheel can store the energy for a number of hours then someone could pedal for a couple of minutes at a time throughout the day and not have to do it at night. This is just an idea that I came up with and if anyone has any ideas I'll be really interested in knowing about it (obviously the above solution is not ideal because they have to put some work into generation but it's the best that I can do).  I've quite recently been looking into different types of fuel cells powered by m/ethanol and others like solid oxide cells and they seem interesting (does anyone here have any experience in building these type of cells?).  This community has a lot of intelligent members who think outside the box so I'm confident that we can come up with something. This ended up being a bit longer than expected and if you've read this far, thank you. I wasn't sure about what section to post this in, square peg is the one I chose out of 5 so if this is wrong please feel free to move it to the correct section. Help and advice will be very much appreciated. Kindest Regards

Generating a Couple of Watts Using Urine?

Hello, I recently came across a paper written by a researcher from a Scottish University about generating electricity directly from urine in a fuel cell and I was wondering if a larger version could be built to generate around 2 watts.  The power per square cm is around 1.5mW so even at 1mW I would need 2000 cm-sq so I think it would be easier to build a stack of cells instead of one or 2 large cells. I'd like to attach the paper but it's one which you need to pay for though I got it for free, could a moderator let me know what to do?  It was written by a Shanwen Tao and called 'A Direct Urea Fuel Cell' DOI: 10.1039/b924786f Another idea I had was to use a small PV setup to generate hydrogen from urine and then store the gas so that it can be used in a hydrogen fuel cell.  I've had some difficulty in trying a to find a cheap fuel cell but then I came across this page: http://www.mtmscientific.com/fuelcell.html Are there any really simple ways of building a fuel cell? I'm posting this here to see if anyone can help me come up with a viable design and maybe even build it for me.  I can pay you for your time and effort; though as a student I do have a tight budget to stick to. Any help, advice and ideas will be very much appreciated. Thank-You

However, when I was looking at a diagram for a regular Army flamethrower, I realized something: The fuel tanks on the flamethrower werent pressurized, and the fuel was pushed out using a pressurized tank that was fed into the fuel tanks. Now here's my question: Because I'm just trying to make a little hand-held that I DON'T need to shoot 50 feet, can I skip the pressure tanks and just jump to a commercial fuel source, like one of those miniature camper stove fuel tanks?

But now that lots of people are buying kits and hiring mechanics to mod their cars to run on french fry juice, the government is starting to take notice. Drivers of these cars now have to pay the same taxes as traditional fuel drivers, register with the state, file monthly reports and payments, as well as make sure they are in compliance with local environmental laws. Noncompliance will be punished with stiff fines.

Help Me Establish Gas Station Fraud- By Exposing Fuel Manipulation.

Prelude:Every week I only ever travel the same route, at the same time, with the same amount of traffic on the road.I fill my cars fuel tank once a week, with $50AU of petrol.The prices lately have been stable and around $1.30AU/LWhat this post is about is the fact that due to me travelling the exact same Km's per week, I have noticed a significant difference between the two petrol stations fuel that I fill at.Can anyone educate me as to why when I fill at one station I get 8 days of travel and when I fill at the other station I only get 4 days of travel?Once again I am filling the same amount of fuel at each station, just one stations fuel (Major corporate outlet) seems to be of a much lower quality.Is it possible that something is a-miss with this situation. Is there a variable im not considering?After 4 months of weekly refills I feel that conclusively, one stations fuel seems to combust better than the others.Is this possible and if so are there any home experiments I could try to prove my theory via testing the fuels combustion/quality.I only write this as I sit here on a week, where I was forced to fill up at the "suspect" station. Im on day 3 now and my fuel is red lining... What is happening?I know the difference of 3 -8 days is a massive, surely others would have noticed this also. I thought I was mistaken the first few times it happened. But now I am positive, something is wrong.I might add, I use premium fuel with the same octane level at both stations.Could that be it? Would they be mis-quoting the octane level in their fuel? That is the only thing I can think of.

Green and sexy car show

The Morgan LIFE car will get it's first UK airing at the Eden Project next weekend.The Morgan LIFE car, probably the sexiest green car in existence is a fuel cell-powered electricsports car built by Morgan Motor Company and startup efficient transport company RiverSimple. Research and development is by QinetiQ, Linde, Cranfield University and backed by BERR. This is its first UK outing.Four stacks of fuel cells convert the hydrogen fuel into electricity to run a super efficient motor generator attached to each wheel. Energy recovered in braking is stored in ultra capacitors rather than batteries, and end to end the performance is estimated to be equivalent to a 150mpg petrol engine. With a top speed of 85mph, 0-60 in less than 7 seconds and a 250 mile range, the mix of technology has been packaged by Morgan to add yet another unique twist to the project. Using only the best and lightest materials, aluminium, wood and leather, the Morgan DNA is clearly visible, adding a new dimension into an environmentally sensitive concept.And Lotus will be showcasing their most powerful Exige yet:The Lotus Exige 270E Tri-fuel is the most powerful version of the Lotus Exige ever, and it runs on any mixture of gasoline, bioethanol and methanol. It is the latest research vehicle from Lotus Engineering, the consultancy division of Group Lotus plc.Emerging technologies will allow alcohol fuels such as methanol, already a proven internal combustion fuel, to be made synthetically from CO2 extracted from the atmosphere. A fuel derived renewably from atmospheric CO2 would be a key piece of the jigsaw allowing society to transfer to sustainable, renewable, carbon-neutral internal combustion.Lotus Engineering is researching the use of sustainable synthetic alcohols as future fuels for introduction within 15 - 20 years.The Exige 270E Tri-fuel is part of Lotus' research into the complex combustion and calibration processes for powering vehicles on mixtures of alcohol fuels and gasoline, which will be important for a successful transition from today's fuels. Its flex-fuel technology gives a practical route to the introduction of sustainable synthetic fuels. Using an alcohol sensor in the fuel system and the advanced Lotus engine management system, the Exige 270E Tri-fuel runs on any mixture of gasoline, bioethanol and methanol. This is all happening at the Eden Project in Cornwall, one of the UK's flagship environmental projects, with some of the world's largest biodomes built into an old claypit.All the major manufacturers will be flaunting their newest, greenest models including Ford, Peugeot, Citroën, Fiat, Volkswagen, SEAT, Honda, Axon, Lotus, Saab and Morgan. Vectrix's electric motorcycle will also be on show, and the hydrogen-powered Morgan LIFE car will make its first public appearance (in the UK).There will also be exhibitors demonstrating how to maintain and even insure your car in a greener way. One stand will feature a driving simulator that they claim can teach you to drive in such a way that your carbon emissions are cut by 15%, there will be a pedal-car race track for the kids, and a Grow Your Own car trail around the rainforest.We visited last Summer, and can recommend it to anybody. If your not aiming for a specific event, go on a Tuesday (it's quieter) and check opening times - opening times on some days are several hours longer than others.Eden Project

British Columbia introduces carbon tax

VICTORIA -- Driving and other fuel-dependent activities are about to get more expensive as British Columbia becomes the first jurisdiction in North America to introduce a consumer-based carbon tax.The carbon tax will apply to virtually all fossil fuels, including gasoline, diesel, natural gas, coal, propane, and home heating fuel. B.C.'s carbon tax, the provincial government claims, will be the most comprehensive in the world.full article

International zero-emmission motorsports

The world's first international hydrogen-powered motorsport race was held in Rotterdam this weekend.Dubbed the Formula Zero championship, the contest pitted teams from five countries against each other in a zero-emissions go-kart race.Each team's entry was powered by a commercial fuel cell that produces electricity from hydrogen. It may be small-scale, with only six teams entering go-kart sized vehicles, but Formula Zero is an officially-recognised motorsport, with plans for scaling up to Formula Three and the Formula One style and speeds."In 10 years if the motorsport industry as a whole hasn't engaged in zero or low emission principles, it probably won't be around," said Greg Offer, who headed up the Imperial College London team. "Teams that embrace this new technology early on will succeed, and those that don't will fall by the wayside."Racing excitement won't suffer, though; Dr. Offer says that fuel-cell powered vehicles don't represent a compromise in performance over traditional petrol-fuelled engines.'"With a combustion engine, you have to reach three or four thousand revs to get your peak power," he says. "With an electric vehicle, it's all there from standing, and they're more efficient." The next races are planned for the US in March 2009. Plenty of time to get your own entry built.Imperial TeamFormula Zero homepageBBC news article

What happened to my penny?!

When I used my newly made wind shield/stand for my alcohol fuel penny stove, the penny was deformed. I was using denatured alcohol for fuel and it was burning well. After it completed my test (boiled a cup of water before it ran out of fuel and without blowing out in the wind) and I was taking it apart to see how well it stood up to the new conditions I noticed that the once shiny penny had been completely deformed. I was wondering if anyone knew how or why this happened.

3X Gasoline Engines Sniff Vapors and Burn Water

Sounds ridiculous doesn’t it? How can water possibly be turned into a useful fuel by just burning it? Sure we can use hydrolysis to separate water into its hydrogen and oxygen gases, and then burn the hydrogen gas as fuel, but that’s not what I’m talking about. Believe it or not, jet engines do it, they have used water to enhance engine thrust, so why not have IC-engines do the same thing? There’s a catch here, since only vapo-engines (  http://goo.gl/QQ42k ) are capable of performing this trick successfully, they must first be introduced into the design mix. Since IC-vapo-engines burn very effectively they run hot, and water would be used as a better alternative than injecting extra wasteful fuel to cool down the engine as is done in today’s engine to prevent knocking. Why don’t we just inject water in today’s engines you ask?  Because they run so poorly already, that the water would extinguish the IC-combustion process. In technical jargon this is known as the ability for an engine to burn lean with an air-to-fuel ratio greater than ~15. Today’s engines can’t sustain a leaner combustion than ~22  without extinguishing themselves. By adding water droplets we further increase this ratio to unsustainable conditions. Unfortunately, this wasteful, richer burning keeps the engine running better by keeping the fuel cooler. In contrast, our vapo-engine is capable of burning unbelievably lean ratios of ~30+. Lean combustion means almost no pollutants and virtually green combustion exhaust products of only CO2 and water. No catalytic converters necessary here, as opposed to running today’s rich engines with their unavoidable polluting exhaust emissions and heavy reliance on catalytic converters. So the irony here is that since IC-engines already run ratty, let’s waste a little more fuel and run richer just to cool down the engine. This prevents engine knocking (the dieseling of an engine due to unwanted, poorly timed, premature combustion) which occurs from the pitiful amount of fuel that does vaporize and burn correctly. Sadly, engineers have cleverly learned to waste fuel for the sole purpose of keeping our IC-engines cool, above and beyond the engine’s normal water cooling system. It gets even better, as the richer the engine runs the more we need to rely on expensive catalytic converters to keep exhaust emissions in check!  Vapo-engines also require cooling, even more than today’s engines, but their advantage is the capability to burn very lean. So instead of ridiculously injecting extra fuel to cool them, like today’s engines, we inject water droplets mixed in with the injected fuel vapor. The water droplets perform three functions; 1) they reduce excess fuel consumption, 2) they cool the engine walls to prevent pre-ignition and knocking which provides better combustion, and 3) they enhance the fuel-vapor detonation force created on the piston from the expanding superheated steam which further helps engine performance. So in a way we are burning the water to generate steam power like a locomotive.

Fuel economy of the world's longest in-service ship

The Emma Maersk is the second longest ship in the world, and the longest currently in service. It's so large, it looks photoshopped into any picture it appears. Driving such a large ship requires a lot of power. From Wikipedia:The Emma Maersk is powered by a Wartsila-Sulzer 14RTFLEX96-C engine, currently the world's largest single diesel unit, weighing 2,300 tons and capable of 109,000 horsepower (82 MW). The ship has several features to protect the environment. This includes recycling the exhaust, mixed with fresh air, back into the engine for reuse. This not only increases efficiency by as much as 12% but also reduces engine emissions. Instead of biocides, used by much of the industry to keep barnacles off of the hull, a special silicone-based paint is used. This increases the ship's efficiency by reducing drag while also protecting the ocean from biocides that may leak. The silicone paint covering the part of the hull below the waterline is credited for lowering the water drag enough to save 1200 tons of fuel per year.We started talking about energy consumption after watching a practice version of Saul's upcoming E-Tech Keynote, Energy Literacy, and Dave Culp of Kiteship and Speed Sailing did a back-of-the-envelope MPG calculation for this ship:A few more facts about Emma Maersk:Running at her rated 80 Mw, her main engines burn 14 tons of residual fuel each hour. Annually, that's 97,400 tons of fuel. Her auxiliaries, delivering their full 30 Mw, burn an additional 6.6 tons/hour, for a total fuel burn of 20.6 tons/hour. Given 290 steaming days/year (80% capacity factor, which is conservative), this yields a total annual usage of 143,400 tons or about $64.5 million in annual fuel costs.Burning 20.6 tons/hour = 6724 gals/hour. At 31 kts/hour, this equals .0046 nautical miles/gallon. At 6076 ft/nautical mile, that's 28 feet/gallon of fuel burned.The 1200 tons saved by her "revolutionary" bottom paint represents a bit less than 1% of this cost, so increases her fuel mileage to 28.2 feet/gallon.Dave concludes:You gotta haul a lot of containers full of $7 tee shirts to make this profitable.28 feet/gallon!Images from jtashipphoto.dk and Wikipedia.
