Gasoline-powered, but no wheels...

I heard about them, but I thought they were a joke.Then I ran across a link.They actually made gasoline-powered pogo-sticks that even grandpa can ride!It's a single-cylinder engine, with the bouncing foot being connected directly to the piston, called the Hop Rod. There are a bunch of adverts and slightly more modern test-drives in a short video on the site.They're... odd.Still, I wondered. Maybe the Hop Rod provided the inspiration for other wheel-less powered transports?Do you remember those Russian boots? 4 metre strides and speeds of 40kph were promised, but that was 8 years ago. According to The New York Times they fell foul of Soviet secrecy and then Russian financial mis-management.They're still around, waiting for some entrepreneur to hop on the band-wagon...

On diesel and gasoline automobiles.

I will get a new used car soon, and am torn on an old diesel 1973 Mercedes and a gasoline 1985 Volvo sedan. A diesel to me is obviously better: more torque, easier to repair, lasts long, but I live in Vermont. And in Vermont, diesel turns to jelly, but I am prepared to deal with it. A gasoline engine, on the other hand, is faster, not what I need, and has less torque. It also stays good in the cold. I would turn the diesel into a veggie, to me that is a great benefit. The thing that keeps me from the diesel Mercedes is the law, you can't by a new diesel, and I can't find where it says I can't by a used diesel. Also, how hard would it be for me to convert to veggie, to get veggie fuel, clean it, and to heat the fuel for winter? There are many diesel stations just sitting around where I live, so that is always an option. Why do I even ask? Because a gasoline would be so much more convenient for me. A Volvo is a perfect choice if I want an easy to use, get up and go car. A Diesel would make me wait for a couple of minutes before I go anywhere. Of course, the final decision of the car I will buy will be totally remodeled into a newly painted, shnaztastic, car with all the means to repair on the road. When I start this summer, I will keep you posted, every step of the way. Post a comment or email me at Stephendanielalverez@gmail.com

8 Reasons you'll rejoice when we hit $8 a gallon gasoline

This article in MarketWatch written by Chris Pummer mostly matches my opinions. My favorite is #2Here is the text:SAN FRANCISCO (MarketWatch) -- For one of the nastiest substances on earth, crude oil has an amazing grip on the globe. We all know the stuff's poison, yet we're as dependent on it as our air and water supplies -- which, of course, is what oil is poisoning.Shouldn't we be technologically advanced enough here in the 21st Century to quit siphoning off the pus of the Earth? Regardless whether you believe global warming is threatening the planet's future, you must admit crude is passé. Americans should be celebrating rather than shuddering over the arrival of $4-a-gallon gasoline. We lived on cheap gas too long, failed to innovate and now face the consequences of competing for a finite resource amid fast-expanding global demand.A further price rise as in Europe to $8 a gallon -- or $200 and more to fill a large SUV's tank -- would be a catalyst for economic, political and social change of profound national and global impact. We could face an economic squeeze, but it would be the pain before the gain.The U.S. economy absorbed a tripling in gas prices in the last six years without falling into recession, at least through March. Ravenous demand from China and India could see prices further double in the next few years -- and jumpstart the overdue process of weaning ourselves off fossil fuels.Consider the world of good that would come of pricing crude oil and gasoline at levels that would strain our finances as much as they're straining international relations and the planet's long-term health: 1. RIP for the internal-combustion engineThey may contain computer chips, but the power source for today's cars is little different than that which drove the first Model T 100 years ago. That we're still harnessed to this antiquated technology is testament to Big Oil's influence in Washington and success in squelching advances in fuel efficiency and alternative energy.Given our achievement in getting a giant mainframe's computing power into a handheld device in just a few decades, we should be able to do likewise with these dirty, little rolling power plants that served us well but are overdue for the scrap heap of history.2. Economic stimulusNecessity being the mother of invention, $8 gas would trigger all manner of investment sure to lead to groundbreaking advances. Job creation wouldn't be limited to research labs; it would rapidly spill over into lucrative manufacturing jobs that could help restore America's industrial base and make us a world leader in a critical realm.The most groundbreaking discoveries might still be 25 or more years off, but we won't see massive public and corporate funding of research initiatives until escalating oil costs threaten our national security and global stability -- a time that's fast approaching. 3. Wither the Middle East's cloutThis region that's contributed little to modern civilization exercises inordinate sway over the world because of its one significant contribution -- crude extraction. Aside from ensuring Israel's security, the U.S. would have virtually no strategic or business interest in this volatile, desolate region were it not for oil -- and its radical element wouldn't be able to demonize us as the exploiters of its people.In the near term, breaking our dependence on Middle Eastern oil may well require the acceptance of drilling in the Alaskan wilderness -- with the understanding that costly environmental protections could easily be built into the price of $8 gas. 4. Deflating oil potentatesOn a similar note, Venezuela's Hugo Chavez and Iran's Mahmoud Ahmadinejad recently gained a platform on the world stage because of their nations' sudden oil wealth. Without it, they would face the difficult task of building fair and just economies and societies on some other basis.How far would their message resonate -- and how long would they even stay in power -- if they were unable to buy off the temporary allegiance of their people with vast oil revenues? 5. Mass-transit developmentAnyone accustomed to taking mass transit to work knows the joy of a car-free commute. Yet there have been few major additions or improvements to our mass-transit systems in the last 30 years because cheap gas kept us in our cars. Confronted with $8 gas, millions of Americans would board buses, trains, ferries and bicycles and minimize the pollution, congestion and anxiety spawned by rush-hour traffic jams. More convenient routes and scheduling would accomplish that.6. An antidote to sprawlThe recent housing boom sparked further development of antiseptic, strip-mall communities in distant outlying areas. Making 100-mile-plus roundtrip commutes costlier will spur construction of more space-efficient housing closer to city centers, including cluster developments to accommodate the millions of baby boomers who will no longer need their big empty-nest suburban homes.Sure, there's plenty of land left to develop across our fruited plains, but building more housing around city and town centers will enhance the sense of community lacking in cookie-cutter developments slapped up in the hinterlands. 7. Restoration of financial disciplineFar too many Americans live beyond their means and nowhere is that more apparent than with our car payments. Enabled by eager lenders, many middle-income families carry two monthly payments of $400 or more on $20,000-plus vehicles that consume upwards of $15,000 of their annual take-home pay factoring in insurance, maintenance and gas.The sting of forking over $100 per fill-up would force all of us to look hard at how much of our precious income we blow on a transport vehicle that sits idle most of the time, and spur demand for the less-costly and more fuel-efficient small sedans and hatchbacks that Europeans have been driving for decades. 8. Easing global tensionsUnfortunately, we human beings aren't so far evolved that we won't resort to annihilating each other over energy resources. The existence of weapons of mass destruction aside, the present Iraq War could be the first of many sparked by competition for oil supplies.Steep prices will not only chill demand in the U.S., they will more importantly slow China and India's headlong rush to make the same mistakes we did in rapidly industrializing -- like selling $2,500 Tata cars to countless millions of Indians with little concern for the environmental consequences. If we succeed in developing viable energy alternatives, they could be a key export in helping us improve our balance of trade with consumer-goods producers. Additional considerationsWeaning ourselves off crude will hopefully be the crowning achievement that marks the progress of humankind in the 21st Century. With it may come development of oil-free products to replace the chemicals, pharmaceuticals, plastics, fertilizers and pesticides that now consume 16% of the world's crude-oil output and are likely culprits in fast-rising cancer rates.By its very definition, oil is crude. It's time we develop more refined energy sources and that will not happen without a cost-driven shift in demand.

Green Crude?

"Sapphire Energy has built a revolutionary platform that uses photosynthetic microorganisms to produce a renewable, high-value replacement for fossil fuel petroleum. This domestic crude oil requires only sunlight, CO2 and non-potable water - and can be produced at massive scale on non-arable land."They call it Green Crude, an algae produced product that could one day replace gasoline. It's not biofuel, or ethanol, and it doesn't require any plants or farmland. The only things consumed are waste water and CO2. They say it could also be made into jet fuel. It seems too good to be true! I can't find anything about the cost, efficiency or speculated time line, but they do have some big investors and are planning on increasing production soon.The CompanyWhat do you guys think?

Would you guys like an instructable for this gas powered bicycle?

I was wondering, who would like to see a detailed instructable with step by step instructions, lots of pictures, and parts lists for how to make this powerful motorized bicycle from scratch (without a kit)? The motor is a heavily modified 79cc horizontal stroke predator engine from harbor freight. The bike has a top sustainable speed of about 40mph. It also has enough torque to accelerate uphill, take off from a standing start with no pedal assist, leave Lance Armstrong in the dust, and do wheelies even with my 29" tires. Gearing can be adjusted for higher top speed at the expense of having less acceleration and hill climbing power. (Although in all honesty, I wouldn't gear it to go much more than about 45). Other features include an automatic clutch, the ability to get 170 miles per gallon, allowing you be cooler than all your friends, and costing a fraction of what you'd pay for a vespa. If you want me to make an instructable, comment below! Also tell me whether you might actually build one, or whether you just want to see how I did it.

Engine Cumbustion & Etc.

I've been knocking around an idea in my head and I was wondering if anyone had an answer to a few problems associated with said idea. One of the problems/road-blocks is how do modern cars run? More specifically, is the gasoline that goes into the pistons for combustion an actual air/gas mixture, or is it air/liquid-gasoline? And is there a way to manually adjust the ratio of air-to-combustible? The reason I ask is because I was hypothesizing whether or not it would be feasible to replace gasoline with a more efficient combustible, and this combustible would greatly depend on what is actually put into a modern petroleum-based car engine's pistons. Thanks for any info!

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.

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.

Construction ideas for this concept?

Recently, I have been working on a gas 'vaporizer' that evaporates gas before being fed into an engine. During my short-term experiment, I found that this saves ~70% (+-20% for crudity of measurement.) This works because the vapors will burn more thoroughly and cleanly, leading to higher apparent efficiency. Below is a basic diagram of how the system works. You can see there is a container that is half-full with gas, and a hose goes down with many small holes. As the engine's compression draws a vacuum on the container, air will come up through the holes. As it rises, the gas-air surface area rises dramatically, leading to the vaporization of gas. To further increase the surface area, I also added a felt liner on the inside to allow the gas liquid to rise and evaporate. The final mixture ends up very rich, so to compensate, a 'T' fitting has been added to allow air to mix in with the vapors/fumes. Some valves have also been added to control the air inlet (similar to a 'choke') and the amount fed to the engine (similar to a throttle. In fact, it is possible to use the original throttle or choke as a throttle on the carburetor on my tractor!) The problem is: My original design utilized a plastic folgers coffee can, and the flimsy plastic top was hot glued to a thicker plastic cutout for strength and support. Since most glues will dissolve in gasoline, including hot glue, it could not be used. most did not hold anyway. I also tried JP weld plastic cement and it did not hold at all. I had to trash this build. I did, however, get enough use to run the tractor for several minutes while testing gas use. I found that the tractor used nearly twice as much simply running on gas than the fumes. I did not have the float valve and electric pump hooked up with the prototype. Also the 3/4in housing I used may be a bit constrictive and also seems to get slightly damaged by the gas. It will not be a long-term solution.  So I need to redesign the project, and I am thinking of using a 1-3 gallon bucket that is sealed or a gas tank. I need good almost air-tight seals on everything. I am asking for any ideas related to the construction of this device and any tips you may have.

The use of gas generators in the home.

Available pluses home gas generators: * Rate per se gas generator compared with the price affordable euro GASOLINE. * The price of fuel is lower than that of the generator on diesel or gasoline. Available Cons: * Gas ​​is considered the most volatile than diesel or gasoline. * Appeal from the gas and the installation of equipment for gas processing requests for special and separate permission. Our legislation prohibited the installation of systems and gas processing equipment in the absence of a suitable plan or agreement. * Most of all, on our market, there are gas generators made in China. * Gas ​​generators are made on the basis of a gasoline engine, the method of adjustment of fuel injection system and fuel carburation. In accordance with this resource from the generator corresponds to the resource gasoline engine. * Later, the acquisition of the gas generator of small capacity, the buyer is faced with a specific limitation on work: a maximum of 6 hours per day. The resource identified by the manufacturers of gas generators, with the first glance quite broad. However, do not understand the root cause of its increase. On average, the share of gasoline engine, out of which gas engines, floats in the range up to 2000 HOURS. This common resource for the euro generator. Imagine the Chinese gasoline engine, the resource is constant. Next, suppose that the resource oposlya changing gasoline engine to natural gas will not decrease. (Our real change of cars with fuel gas indicates a reduction of the resource engine, which originally was made for 1-octane gasoline, well, and subsequently applied for another). 1 of firms offering gas generators, a guarantee in 2000, machine hours, or one year, although with the limitation, at least 6 hours per day. The appointment of such a generator is not clear. As a source of constant power, he will not do, as backup - as well as the first blackout since most 6 hours (which happens often) determines the total loss of warranty. It is reasonable to imagine that the buyer, which turned off the light of day, will not sits all day in the absence of light, zhdya coming the next day. In general, in fact, a similar limitation on the work looks pretty amazing: It seems as clear that the miniature generator with cooling air is not able to operate around the clock. While that still causes inconvenience to cool the generator, for example, for 1 hour, and then resume his work? In solid power installed thermal disconnector, which simply will not allow too much power to warm up, and therefore, the decision on mode of operation.

Can Non-Hybrid Cars Get 100+ MPG Today?

  We're not talking about hybrids here; our topic is cars powered by the basic IC-engine that relies on gasoline and not electric motors. Today's gasoline engines are not designed to combust/burn gasoline efficiently. Even with the advent of using high pressure fuel injection techniques that are computer controlled, we still fall short of the mark. Partly because liquid gasoline can't burn, only gasoline vapors burn, and there lies our problem. The same goes for injecting the high pressure droplets of fine-mist liquid gasoline that enters the engine cylinder using our current nozzle ejector technology, it doesn't all burn at the same time! Engine designers assume that these droplets are instantly vaporized by the engine's hot cylinder walls, and then instantly explode/combust when ignited by the sparkplug. Not true, up to 2/3 of the fuel isn't vaporized and doesn't combust until later on in the cycle. The 1/3 that gets almost-instantly vaporized and burns will do so within the several thousandths of a second (Fig-1) it has before the piston moves down its 1/2-stroke (out of today's 4-stroke cycle) completing the engine power-portion of its cycle. This releases power and tremendous heat which indeed vaporizes the remaining ~2/3 of our fuel from its liquid droplet form, but too late. It essentially does so when the power stroke is almost over or the piston is just about ready to move into its up-stroke (2nd stroke of our four stroke cycle) phase. So, because of poor vapo-timing we have 2/3 of our fuel virtually wasted by exploding at near the bottom of the power stroke. This incorrect explosive timing, which happens to most of our fuel, imparts very little energy into the crankshaft because its effective "moment" (a product of explosive force and radial-component distance from crankshaft center) is insignificant by then. Various attempts at adjusting the combustion timing spark hasn't made a significant difference. Even though ~2/3 of the fuel is now exploding and providing a huge force, its small "influence" arm distance is rapidly diminishing to zero, and any huge downward force times near zero arm-length is still zero. Some clarification here, technically thermal-efficiency is not improved, pretty much all of the gasoline gets combusted today. That means the energy of the fuel is almost totally released, but not effectively used. The problem is the timing it takes to convert fuel-injected gasoline droplets into vapor to combust at the correct engine rotational time and extract that expended energy. If you did the math for any size engine rotating at say 3200 RPM, you would find that a 4-stroke engine can only extract that energy from combustion during one of the four strokes. And the time it takes to make that stroke happen is only about 9.4 thousandths of a second or 9.4 milisecs (msecs). Now picture the piston just below TDC, all its valves closed, under pressure and containing all the fuel and air it needs to combust. At this point our deadly cocktail has about half of the 9.4 or about 5 msecs to complete combust after the timed sparkplug ignites it. The half factor exists because the max portion of our power stroke (moment arm) occurs at the mid-stroke of the piston sliding down and turning the crankshaft. If all of our fuel isn't combusted by then, the moment-arm or distance from the piston-center to the crankshaft quickly reduces to zero. Again, only vapors combust within a healthy 2 msecs (Fig-1), while fuel droplets take a relatively long time (>5 msecs) to vaporize before it can combust. Unfortunately nature is stubborn and vaporizes ~2/3 of our injected fuel droplets only during roughly the second half of the power stroke. So this huge amount of energy gets wasted because even though the forces of combustion are huge, its moment arm is rapidly approaching zero. Infinity times zero is still zero! Engine designers/engineers have been plagued by this phenomenon ever since the creation of the 4-stroke gasoline or Otto cycle engine. We need to improve this intermittent combustion/explosion process by combusting all of our injected fuel at the correct timing sequence. This is accomplished by injecting only vaporous fuel which will produce ~3X the power we now get. Another way to state this is, for the same power that we now get from a gasoline engine, if we burned the fuel correctly, we would only need 1/3 the fuel consumption to get 3X the current MPG.

A question for/about Vegans...

In Belsey's fabulous ible Vegan Egg, it's states that "Vegans won't eat or use animal products..." Which begs the question:  Is it unethical, or unprincipled for a Vegan to drive (or ride in) any vehicle that consumes gasoline or deisel?  Afterall, fuel is an animal by-product.

How to prevent gasoline fumes from seeping into my house/garage from a neightbours garage?

Hi all, Back again with another issue regarding the money pit. I live in a townhouse and my neighbours have two motorcycles in their garage. They leak gas and I am guessing pretty badly because I cam smell it in my home. When their garage hasn't been opened in awhile it's fine, but when it opens, I am supposing the pressure builds up and BLAMO It comes through the vents in the house or around the vents in the house. My garage even smells strong of gasoline and I have nothing in it that uses gas. Is there anything I can do? Besides to obvious and talk to the neighbours, and the condo corp, two things I have already done. It wasn't bad in the summer because they were in and out and the windows were open so there was less pressure, however, when I arrived home last night it smelled like a flippin gas station in there! I am waiting to hear from the condo corp, trying to be proactive because clearly this issue isn't one they are tending to with immediacy

Air sample analysis for the concentration of CO2/Carbon Dioxide? Answered

I'm working on a high school science fair project which concentrates on the CO2 emmissions of automobiles and anlyzes two methods of filtering CO2 from car exhaust. It's really a pretty simple project - except that i don't have a Carbon Dioxide monitor. Online they range from $200-800 and i've contacted the enviornmental department at a local university to see if they can help me. I'm still waiting on a reply but i'm wondering if any of you guys (or gals) have any ideas on how i can find the concentration of CO2 in car exhaust.
