What's your favorite alternative fuel?

Apr 24, 2007 10:45AM PDT

What's your favorite alternative fuel, and why do you think it's the best? Does it offer a possible long-term replacement to gasoline? I've covered some current alternative fuels in my column, Your clean, green car choices.

Electric Future ( with Butanol and Biodiesel for antiques)
Apr 26, 2007 5:45AM PDT

Electricity is clean, efficient, cheap, and comes from many diverse sources. Electrical production and distribution systems are in place, and are more efficient than the production and distribution of any other fuel. Current LiIon batteries give good power and range. More advanced batteries (Li Sulfur, Li Air, Al Air) are in development, and could give greater driving range than any petroleum fuels. Aluminum-air and zinc-air fuel cell batteries can be refueled quickly with fresh metal fuel. Construction of powered guideways that provide electricity "on the go" will eliminate the "short range long trip slow recharge" problem.
But what about the older vehicles that don't run on electrons?

Butanol is nearly perfect for old gas guzzlers, it can be made from any biomass feedstock used to make ethanol, but unlike ethanol does not require special engine modifications. Butanol has more energy per gallon than ethanol, and unlike ethanol has little adverse effect on milage.

Biodiesel is for diesels (natch), and can be made from various oils and fats. Certain algae are very prolific oil producers, and in the future may be the main source for biodiesel.

As for the other "also rans":

Natural gas is the only "fossil fuel" with a renewable source, clean burning, but requires high pressure tanks for automotive use. Best reserved for stationary heating applications.

Ethanol is clean burning, but is inferior to Butanol as a fuel.

Hydrogen is clean, but expensive, inefficient, and extremely bulky. Driving range is a bigger problem for H2 than it is for electrics! Best reserved for those rare special applications where its high energy/low weight overrides its many serious drawbacks, such as fueling very big rockets and perhaps some large planes.
"Coal-to-liquid", oil shales, and tar sands all rely on limited fossil fuels, are expensive, will have to compete with biofuels, and are far too expensive (and polluting) to compete with electricity.

Potential energy leads for future
May 2, 2007 5:53PM PDT

Excellent summary of what we can foresee now. I fully agree with the long term possibilities that will be at our disposal:
Electricity for cars, trucks, buses and trains
Hydrogen for airplanes and boats?
How about atomic energy for big cruise and transportation boats?
I tought that Hydrogen had all the features necessary to be "the" energy for the future but its dangers and bulky storage make it very difficult to use in cars.
The only issue is that we will have to step up the speed at which we are progressing right now and I am not sure that the car manufacturers are very enthusiastic about this. How about a world financed research?

Outstanding Post, Albizzia!
May 3, 2007 12:32AM PDT

I too believe electric propulsion is the best power for our cars in the future. Exciting initial offerings from Tesla Motors and other electric car makers coming soon will "jumpstart" a massive shift in current thinking to at least acknowledge electric cars. Electric autos, with a huge advantage of near maximum torque across all motor speeds, no tailpipe emissions, and a much simpler alternative to the complicated systems req'd to power and manage IC cars will begin to get more people's attention. Further advances in battery technology that address range, and recharging will continue the push, and (somewhat) quiet the naysayers. But is there any good news concerning the battery recycling issues?

But what a great post you wrote! I've read a number of Internet articles concerning the subject, and others that dig into alternative fuel energy content, but you introduced in just a few sentences a number of new items to me to further look into:

1. Battery advances (Li-Sulfur, Li-Air, Al-Air) - hadn't heard of these at all before reading your post!

2. Butanol and the quick comparison to Ethanol - while I've been very skeptical of the ethanol plant frenzy, I hadn't heard of butanol and its (a.) energy superiority to ethanol; (b.) mileage superiority to ethanol; (c.) lack of engine modifications req'd. as compared to ethanol. So, I'm curious - What about pipeline transmission of butanol - compared to ethanol which has to be trucked? What is the ratio of req'd energy to produce butanol vs. energy realized in finished butanol? (superior than ethanol's I would guess) - or at least a valid argument on this if speculative? Is butanol a gasoline additive like ethanol, or a stand-alone fuel? And finally, why the hell are we fixated on ethanol vs. butanol? (I know, no real answer to that one...)

3. Algae as an oil-producer for bio-diesel... Very cool! - and again had not read or seen anything on this before.

Anyway, I just wanted to commend you on your post. It isn't often I see so many insightful and novel subjects in a concisely written post.

Cellulose is more the answer.
Jul 25, 2007 8:17AM PDT

Well it is nice to see someone may be picking up on how the future may lay out. And when everythind is said and done, the answer will be cellulose. I have a process that separate the O2/N2 molecules from a stream of air such that I currently have a 40% O2 stream. Now If I run this through succesive interations, it becomes higher. The thing is that I can use cast magnets instead of the electromagnetic fiels I use for my model. I cam across this thread, because I need to determine how best to suspend the cellulose in a liquid form. I want to just use water. Hopefully in the next few weeks I will be able to fire my combustion chamber on this Cellulose/Water mixture. Now for you grean folks, Cellulose is one of the most plentiful compounds on the planet, and properly oxidizing it produces CO2 and water. Plus this material is part of the closed carbon cycle. So whatever I oxidize will be part of the next growing cycle. By only using cellulose, we can harvest a percentage to be returned back to the earth, in the same way coal and oil deposits took it out of the atmospheric cycle to begin with, thus returning back to normal C02 levels. The proper oxidation of cellulose is the goal here, and that is why life in general on the planet revolve around it. The problem is that you have all bin suckered into believing that the fuel was the important part. By controling the Oxygen side of the formula, you can do amazing things. When have you ever heard of someone manipulating the Oxygen content to any combustion process. And ask yourself, if this nut has gotten to 40% what does this doe to efficentcy numbers. My crude model changes any combustion process to one over 200% efficent to current standards, and if I could get to 100% it would be over 400%. By controling the oxygen we can make the wourld less flamable in general, but like usual, we alyays have to do the opposite, like make it more explosive with hydrogen. So on the 27 I have a meeting with one of the venture capital groups in Palo Alto. Maybe soon, I can find the additional team to help me move this forward.

how do you think hydrogen is produced?
May 3, 2007 8:25AM PDT

electricity + hydrocarbon (most likely fossil fuel) = hydrogen + carbon fuel source burned to produce electricity.

or a less efficient process:

electricity + water = hydrogen + oxygen

and where does all that electricity come from today?
Yep, fossil fuel.

So, a hydrogen power car is worse than a battery power car in terms of CO2.

Electric is nor derived from fuel
Jul 25, 2007 9:38AM PDT

Electric is produced via magnetism. The use of fuels is to spin turbines or generators that create a magnetic field, which also produces an electric fiels at right angle to magnetic flux.

The idea that fuel must be used to get electric is a myth at best and a shameful lie at worst. Hydroelectric does not burn a fuel, it uses the pwoer of falling water to spin the turbines.

Electric car is the answer....not
May 3, 2007 11:15AM PDT

There are several problems with electric cars-
1. It takes a plethora of nasty chemicals to make a battery (not really environmentally friendly), and when they crash, all those nasty chemicals turn the accident into a nasty Haz-Mat incident. Cars crash everyday.

2. Electricity is not just pulled out of a light socket by fairy dust! We predominantly burn fossil fuels to create it. Then you have to push it down a wire (where you lose a little), into your house (where you lose a little more), convert it to DC (even more lost), then into your car (more still). Then, if you don't run your car regularly, the battery will discharge over time. Doesn't sound like the most efficient way to use fossil fuels if you ask me. Solar systems on our houses would help (I am a big proponent), but as for electric cars, see #1.

Bio fuels may work, but I can't see us growing our way out of energy dependence. One way or another we have to use water to grow bio fuels. Water is getting harder and harder to come by. What's the answer, I dunno. But fancy golf carts aren't gonna do it!

Problems for electric cars... not
May 6, 2007 5:40PM PDT

1. There are many different types of batteries with many different chemistries. Some types have potentially hazardous chemicals (lead acid, nickle cadmium) but other types are not considered to be highly dangerous. LiIon batteries have some potentially flammable components, but are not considered highly toxic, and have no corrosive components. LiIon batteries are less flammable and less toxic and less hazardous than gasoline. How often do we call the "hazmat" squad for a gasoline spill at a car crash? Not often.

Zinc-air batteries are not toxic, flammable, or particularly hazardous.

2. Yes I do know where electricity comes from. It has many power sources, some are quite clean. As more renewable sources come online, the percentage of fossil fueled electricity continues to decline. The fossil fueled electric plants are 45% to 60% efficient, and the "grid" averages 95% efficient. Charger and batteries are 85% efficient, electric motors over 95%. Compare that with 15% to 22% for spark IC engines, 25% to 30% for diesel and 30% to 35% for hybrids. Even when powered by "fossil fuel" electricity, electrics are still more efficient and produce less CO2.

Electric cars can be fast and powerful. How about 0-60 mph in 4 sec. or less? Top speed way above the legal limit? That ain't no "fancy golf cart".

DOD study and project moving to shale oil fuel extraction
May 4, 2007 2:12AM PDT

There is a DOD powerpoint presentation that shows their progress toward developing one fuel instead of the 7 different grades now purchased, stocked, transported, distributed etc. to support our military vehicles. Their studies show that there is one US shale oil field that alone will be able to replace all non US petroleum needs for a long time.
Major oil companies are working on extraction and processing this source which makes a fuel with no sulfer and no CO2 fuel. By products of the extraction and production process are electricity and Hydrogen. Watch for more news about it in the future.
Personal opinion, after the first Hydrogen tank explosion that wipes out a neighborhood, that fuel for vehicles will be a dead duck. Propane has the same problems and has found a good market, but nobody puts a propane tank in a vehicle on the highway for a good reason.

Who says you can't reinvent the wheel?
May 7, 2007 9:24AM PDT

I think everyone has missed the obvious because its too simple.
Energy can be stored in the rotation of a mass...a wheel. The amount of energy stored is proportional to the mass and the square of the velocity (which depends on the diameter). Its Kinetic Energy only going around in circles. Flywheels are as simple as it gets: One moving part! To negate the adverse gyroscopic effect, two counter-rotating flywheels could be used. Just "plug it in" and it winds up. With motor/ generator coupling, regenerative breaking is the obvious choice. And you're right: the distribution system is already in place. Every lamp-post becomes a refeuling station. On the downside: it will fly apart if it becomes unbalanced so proper containment in the event of a collision is a highly recommended.
That's my choice for the way to go in personal transport.

Electric/Hybrid-Plugin
Apr 26, 2007 9:25AM PDT

I drive a 2003 Civic Hybrid. I've already driven about 100,000 miles and I love it. I loved it more as I saw the fuel price rise from $1.23 to $2.90 here in VA. In the 5 years that I've driven 100,000 miles, I've gotten a realistic 40mpg, which is close to 1/2 the average vehicle in the US. That means I've conserved about 50,000 miles worth of fuel, and that feels great.

But I saw a documentary titled, "Who killed the electric car?", which made me realize that hybrids are yet a compromise. GM had a viable electric car that people were lining up for, and they were improving the battery to go from 60mi to 200mi per charge. But the only reason they created and leased that vehicle was because they had to comply with a zero-emissions ruling in California. That was back in 1996. Imagine what the technological advances to that electric car would have been in the last 11 years! It would be very easy for GM to bring back the electric car, with today's improved technology, and begin distribution. But it's not in their interest to release a vehicle that requires far less maintenance and cost. Since the large companies won't make it, smaller companies like Tesla have to create the vehicle. But they can't easily institute electric charging stations across the country for 10 minute charges to charge 85% capacity.

If one were to purchase a brand new Toyota Prius and get the $10,000 plug-in system installed on it, they could get 150mpg right now, with today's car. That would be a new Toyota for $30,000 that gets 150mpg.

Currently, the Prius w/Plugin is the best. But an electric car would be the best solution (I hear Tesla is designing a family vehicle for under $50,000). Too bad the large car companies won't make and sell it.

Hybrid cars

What we have now are gas engine hybrids supplemented by electric motors. Why not reverse that and have an electric car supplemented by an engine. The battery would be charged overnight from hydro and that would be sufficient for normal daily use. On long drives the engine would be used only to charge the battery so it could be run at it's peak efficiency.

- Collapse -
I agree with this and for this reasons:
May 3, 2007 2:20AM PDT

In my opinion we will have to go to a mixed solution of electricity combined with an alternative fuel like hydrogen or biofuels.
Why? I think that for our total energy needs we will ultimately be forced in a non-petroleum period to go to clean ELECTRICITY based energy. For that we are in the right direction if we develop solar energy (voltaic and termal)combined with energy from alternative, clean and renewable sources like wind, hydro,geothermal or whatever possible.Part of this energy will be used to produce the "cleaner" fuels needed for transportation.

Existing nuclear power plants (already written off for many years now) should help us to free money to develop those "new" energy sources. The governement must regulate,starting as soon as possible, this issue to stimulate the change otherwise we will miss the momentum to do so....
SO: NO cheaper power for the consumer but money to invest in the future...

Just some figures to make you dream:

140.000 Terrawatt (TW)(Terra is 10 with 12 zero's behind it!)from the sun gets through the earth's atmosphere every year: this means that every HOUR the sun delivers 16 TW to the world or, the energy that the whole world is consuming in one YEAR (you get it?)
IF we use only 0,16% of the earth's surface to fill it up with solar cell farms (with the cheapest cells giving only 10% efficiency) we can reach this energy level...
Nevertheless, a 500 MW plant would cover 32 square kilometer (or 12.355 square miles for the non-decimal guys)
And, very important,you know it all: the sun doesn't shine at night ...so other sources(wind,etc) will stay necessary!

2. You are connected to internet reading this. An estimation I read some time ago of the number of servers used on the net was about 30 million. At 800 W per server this gives an energy need of 24 GW.
If you add the peripherial equipment (cooling,..) it can go up to 57 GW.... and that is without yours, mine and all the single computers connected... and this is still growing!

Gas Electric Hybrid Protocol differences
May 4, 2007 2:21AM PDT

Congratulations, you have just described the protocol the software on the Toyota Prius Hybrid uses. Starts driving on elect, gas engine starts when more speed or power is needed. Works best for in-town start and stop and go driving. 2. The Honda Civic Hybrid protocol in the software is different, Gas engine starts up drives car, uses electric for faster acceleration and to regenerate electricity when slowing down saving energy in the batteries. This gives best milage at a sweet spot of 73mph in cruise of 44 mpg. Look for vehicles that will allow user to switch mode of operation or be more flexible and let the computer change mode based on driver and driving conditions.

Fuel is that what you burn?
Apr 26, 2007 11:20AM PDT

Gasoline, natural gas, and other fossil fuels come to us with because we put energy into a system to collect and distribute them. They have been produced over time by collecting the energy of the sun and earth which have condensed them into highly portable fuels.
Hydrogen fuel cells, batteries, biofuels all require large input of energy over a shorter period of time to create a portable fuel. Most unfortunate that most of this energy will come from the fossil fuel base. They neither end polution, nor save resources.
We need a non-fossil fuel energy base, fusion, fission, solar or beamed radiation. Given enough energy, which does not depend on fossil fuels and I will condense enough CO2 to end gobal warming. (How big do you want your CO2 fire extinguishers?) Then with large amounts of energy you can pick the method you want to create to have portable fuels. (many will work)

Apparently you are a thinker...
May 3, 2007 1:18AM PDT

I applaud your thought into your answer, and not taking the 'knee-jerk' superficial options. The nasty truth, as you so efficiently explained, is since we don't use very much Nuclear, Solar, Wind or even Hydro systems to generate that "Clean Electricity" to use, we rely on nasty old Coal, Oil and natural gas to generate the "Clean Electricity" we are putting into these electric cars. Until we replace all those coal and petroleum power plants with Nuclear, Solar, Wind and Hydro-electric power plants, electricity will be as dirty as gasoline, you just won't see if coming out of the tail-pipe, which I guess if you don't see it, no foul, right?! The most efficient power generation at this time, is nuclear, but then your are left with all that nuclear waste to dispose of!

I recently read about a new sports car that is an electric hybrid - it uses a gasoline engine to recharge the batteries. It has a top speed of 200 mph and gets approximately 200 mpg. It can go from 0 - 60 in 3 seconds! The manufacturer of the car is offering his technology to any automaker that will accept it. Also, a company called EEStor in Ceder Park, Texas has developed an "Ultracapacitor" that carries enough charge to give a automobile a 500 mile range and it can be fully recharged in 5 minute!(http://ohgizmo.com/2006/09/26/eestor-ultracapacitor-5-minutes-to-charge-500-miles-per-charge/)

As for petroleum, according to what I have heard from various reports, the U.S. has some, if not the largest oil reservoirs in the world. The Gulf of Mexico, is considered to be the largest, if what I have read is true, but there also is a enormous deposit under the Rocky mountains, as well as vast amounts trapped inside the oli shales, as well as in Alaska. In fact, we enough petroleum to last us for the next 200 years, unfortunately, EPA and various organization such as Sierra Club, Green Peace and other such groups, lobby hard to keep us dependant upon foreign source of petroleum. The simple fact is this, even if a new, super-duper electric auto came out today, it would be 10 to 15 years in getting everyone switched over, as most folks can't just run out and buy a $20+K auto. So petroleum is going to be around for at least another decade, and I suspect. We have to be very careful not to respond to "Knee-Jerk" decisions and half-baked hype about this alternative fuel or global warming (which is a total farce). We must carefully think the problem through before we act and try to adopt or we will only exacerbated our energy problems. Case in point is the rising natural gas prices and food prices because of the big push to produce ethanol due to the increase demand for natural gas and corn to produce the ethanol! To top it all off, ethanol get 30% poorer gas mileage which means you will have to purchase 30% more to get to meet your transportation needs! Ha Ha Ha! Are we learning yet?!

Great Lobby for Oil
Feb 21, 2008 4:35PM PST

Truth is electric is the most efficient power for transportation, and that is why it drives locomotives. It problem is in the generation of the electric. For Hybrid vehicle to be most energy efficient, the internal combustion engine needs to be reduced to that of the power generator, but only when there is not sufficient energy in storage or alternative generation sources.

Small vertical wind turbines can be placed along busy highways, where there is always sufficient turbulence to provide energy. In addition to providing the necessary energy for lights and signs, they can also provide plug in rechargers at rest areas. And since we are are a capitalist nation, the state can charge a fee as a toll for highway/electric use.

Regardless of where oil is obtained, the price of oil is going to stay high and the price for a gallon or liter of fuel is going to rise. Increasing demands in China and India will keep prices high as the market will bear, so it remains in our best economic interests to seek and employ new technology to remove our dependence on oil and oil products as the main resources for transportation and electric power.

Electric vehicles were pushed out of the mainstream twice. The first time was by Henry Ford and a blue collar priced auto than ran on gasoline. Then later with GM and the EV1 which is debated as to who really killed the electric car then. Both Ford and Toyota were readying for mass market electric.

Because the fuel to generate electric was always abundant and cheap, so was the price of electricity. Inefficiency in the grid was negligible because the volume of consumers and the demand was still profitable. But as the price for fuel rose, so did the cost get passed on to the customer.So you are right, our oil demand does not make transportation an exclusive consumer of fuels. There is research and development to make more efficient power transmission devices, but the cost of fuels is what power utilities will justify as to why they cannot afford to purchase these new devices.

Electric drive, electric cooling and heating as well as power steering and brakes all electric. Batteries, capacitors, electric generators and motors for power train and accessories. Solar and wind, regenerative braking, and small fuel engines to power generator(s) when everything else is still not enough.

It's a process, not an answer.
Apr 26, 2007 2:30PM PDT

That's the hardest part of this whole debate: We expect another gasoline to emerge but I don't think we are heading toward another cut & dried answer for powering cars (notwithstanding a really strong lobbying effort by one of the alt fuel advocates that forces our hand as a society).

Rather, we may be heading toward a long period of mixed approaches to powering cars. There's something inefficient about that at the macro level that I suspect is not good for someone's economy (almost certainly that means yours and mine!)

We just finished shooting a series on several of these options and I have to tell you EV's seem to make the most common sense among alt powertrains. But where will that electricity come from? If it weren't for nuclear's P.R. disasters of the 1970's, we might be seeing a nice synergy of battery R&D, nuclear power generation, and electric cars coming to the fore. But no.

The AC electric motor is torquey, highly-developed, quiet (though most acutally make a rather cheap, grindy, unsatisfying sound), very low maintenance and can make a car go like hell. But then there are those toxic, cantankerous batteries.

Hydrogen doesn't *want* to be what it *must* to be to become an effective auto fuel, whether we burn it or convert it. It seems like a cocktail of sci-fi and wishful thinking. And it may be that the various bio fuels are just tepid replacements for a smallish portion of our gas/diesel consumption.

Who knows, maybe we're just heading into the period of the . . gas engine. If we can reduce its fuel consumption as much we've reduced its emissions over the last 30+ years we would make a huge impact on our oil consumption. We must keep cleaning up the emissions even further with hybridization, more advanced catalytic converter technology, more precise fuel metering & engine management, etc.

I recall how clean air standards introduced in the 70's were decried as impossible to meet and thought to be the end of the gas engine, the large car, the V8, etc. We went through almost 20 years of hell as cars lost most of their power and became amazingly unreliable. It was a national R&D program carried out in new car showrooms. It was a bad time. But in the end, the gas engine car emerged as a machine with a degree of relative cleanliness unimaginable in 1970. And faster & more reliable than ever imagined, as well.

Refining the gas engine isn't sexy, and that's a huge knock against that course of action. Carmakers won't be able to polish their brand by doing it, and venture capital won't be chasing young companies doing it. Plus it doesn't get us out of places on earth we'd rather not be. But "fixing" the gas IC engine fits all the *mainstream* comfort zones: Consumers, industry, government, and the capital markets.

Are we absolutely sure the IC engine is at a dead end? I've heard that before.

Cars, Energy, and the Structure of the Built Habitat
Apr 27, 2007 1:16AM PDT

With such a collection of smart readers and posters, I'm surprised no one mentioned Personal Rapid Transit systems, vanadium redox, and block, encapsulated, and liquid hydrides. I think what we often overlook in these kinds of discussions is that side-by-side comparisons between alternative forms of 'fuel' are somewhat disingenuous because of the fundamental logistical differences each come with. The root problem of renewable energy is, and always has been, that our built habitat is physically structured around the specific forms of energy we use. Given our inconvenience-averse (let alone, reality-averse...) culture, alternatives are therefore compelled to radically out-perform previous forms to compare favorably and gain acceptance when, in fact, they could be perfectly functional in a habitat that properly accommodated their differing logistics. Or to put it simply, we demand far more out of alternatives than we do from the conventional to avoid the inconveniences of changing our behavior and lifestyle. We'll forever declare hydrogen use not 'practical' if we have to change how and where we live and do things in order to use it efficiently.

The structure of our built habitat is largely determined by the logistics of the forms of energy we use. Before fossil fuels, civilization was physically clustered almost exclusively along coasts and waterways. With coal and the advent of rail systems to move it, energy -and therefore civilization- could be distributed across long, albeit few, lines of communication creating a more dispersed habitat. With the advent of oil and gasoline and the asphalt road to distribute them, the habitat exploded in all directions. We live in places and ways thanks to gasoline that other forms of energy don't necessarily allow for with the same degree of convenience. These historic transitions in mode of energy use were easy because they accommodated the human desires that accelerate growth. They made peripheral real estate more valuable by making it more convenient to access and develop. Renewable energy says to us; "you can live well -even better and healthier- but not necessarily in all the places and ways you're used to" and so because we resist that inconvenient change in lifestyle and the possible loss of value of some real estate we demand the technology make up the difference in defiance of physics or we'll 'damn' the form of energy as impractical. The electric car has ALWAYS been practical in the context of a specific lifestyle. There was a time in America when there were more of them -and more companies making them- then fuel powered cars and that was fine because most people lived in cities and used rail when they traveled long distances. It's only less practical today because of the context of the way we live today. You could say that the resistance to alternative energy has more to do with property values and our personal resistance to change than the technology of alternative energy itself.

Alternative automobiles have always been something of a red herring in the politics of energy. Vested interests know that the nature of the automobile as a small scale mass produced product with an entrenched industry and a vast installed user base presents a greater technological challenge to renewable energy implementation than other larger scale and stationary systems like municipal and home power, rail, and shipping. By coercing our car-obsessed society into thinking that the credibility of renewable energy is contingent on its performance in the form of the automobile it provides a convenient excuse for ignoring implementation of it in these other forms -which would over time establish the infrastructures and physical transformation of the built habitat that ultimately would make it practical and convenient at the personal transportation scale.

We think too much like consumers, expecting pre-packaged solutions to the world's problems to be offered to us as a passive consumer choice. We face crisis today that are a consequence of the dysfunctional structure of our civilization. There is no 'product' that is going to fix that. We can't just buy our way out of this mess. To address these problems we have to all learn how our world works as a system and implement changes to that. We have to reprogram our civilization, not just pick a different car.

We have been intoxicated and awestruck by the flame. We have come to depend on the flame for heat and light, and for defense. And so we have totally ignored what nature has provided us in the way of energy, constant never waning energy that permeates the universe.

Before we had elctric, heat and light came from burning something. But with the generation of electricty, came a new paradigm in energy use, but not in its production.

Viktor Schauberger (sp?) and Nikola Tesla independently made some rather interesting observations regarding to dynamics of water. Schauberger stated that fish "swimming" up a waterfall, were not actually swimming, but rather guiding themselves into a current that seemed to flow in the opposite direction of the falling water. He firther postulated that the water was acctually creating an electromagnetic current in which the fish "swim" up the fall.

It is runored that he was able to use this discovery to create a flying disc that was literally powered by water, which was capable of generaating huge amounts of electromagnetic energy.

But I digress, so back to the issue of alternative fuels. It has been long believed that you have to create electricity from something else, but nature proves daily that is not true. Lightning can certainlt burn, but it is nor created from fuel burning. The Laws of Conservation of Energy says energy cannot be created nor destroyed.

As I wrote in previous posts Tesla also discovered the "cosmic energy" but could not get banker J. P. Morgan to finance his work, since Morgan saw how he could make much more money selling electricity. Today we are faced with a similar problem.

The argument is simply a matter of economics, but not yours or mine. It's the oil industry, the energy (electric utilities) industry, and even the medical industry.

Okay, so here is the punch line(s) as I see it:

1. We can create devices that tap into the Aether energy to produce an electron flow without expending energy to do so.

2. Our health will become great when we are able to produce foods without chemicals, where the land that it grows on is allowed to replenish itself naturally, and not through chemistry.

3. The cures to all disease will not be a drug, but is a electromagnetic frequency that can destroy bacteria and virus.

Bottom line is that the world has always had the power, it just has been kept from the people and used to control.

Alcohol is the way to go for now
Apr 27, 2007 2:41AM PDT

The current gasoline distribution infrastructure will serve nicely for alcohol distribution and modern engines can be modified to burn alcohol without much trouble. In the long term, fuel cells, with the addition of a reformer, can use alcohol. There is work ongoing to produce fuel cells that use alcohol directly. Since we already make significant amounts of sugar from sugar beets, why could they not be used for alcohol production? It seems that sugar beets would be more efficient than corn in producing alcohol. Large areas of dthe south along the Gulf Coast should have conditions that would alow sugar cane to be grown.

My biggest problem with hydrogen is the fact that a cubic foot of hydrogen does not have very much energy unless it is under high pressure or in lquid form. For fueling stations to have high pressure (I have read studies where numbers on the order ofr 10,000 PSI would be needed) tanks is bad enough, but to supply the fueling stations by tanker truck at those pressures scares the daylights out of me. Using tens of thousands of miles of high pressure pipelines is not any more comforting. To get hydrogen into a lquid state requires wicked cold and high pressure. at the necessary temperatures, steel is a lot like glass in that it does not bend, it shatters.

I feel that instead of spending huge sums of money in disrtibution infrastructure, alcohol makes the most sense.

why not pour a few pounds of zinc powder in and go

Use Zinc Air Fuel Cell add a few pounds of zinc powder and you are fueled and ready to go another few hundred miles.

The ZAFC is the perfect alternative power source for both automotive and emergency standby power generation.

Alcohol not H2 is Stored at the Service Station
Apr 27, 2007 6:44AM PDT

You are right on with the alcohol being a great answer for minimizing infrastructure costs. Ethanol would be trucked (atmospheric pressure) to the service station and stored in tanks that minimize water invasion.

Then a local high pressure tank would store hydrogen reformed at the service station, from that ethanol, at a pressure likely to approximate GM's new storage tanks.

When you drive in the station, a "robot" type mechanism with machine vision will guide the nozzle to your tank opening. A computer signal will tell the service station to start pumping. Your tank will fill up quickly with a high pressure hydrogen. You will drive away smoothly and adroitly (and quietly) in your new Mother Earth car or truck!

Conversely, competitors, likely from Germany, will try to outperform this "GM type" system by trying to sell onboard reformers. It will be an interesting competition.
