Hydrogen RX-9 rumors pop back up
Mazda is in a unique position in the automobile world with its rotary engine. The Wankel engine happens to run rather well on hydrogen and is not as susceptible to many of hydrogen's shortcomings as other internal combustion engines. The Japanese automaker has had hydrogen-fueled rotary-powered cars on the roads for the last few years and the automaker has previously suggested that it hopes to have a hydrogen-fueled car in production within the next five years.Auto Motor und Sport is now suggesting that Mazda's next-gen rotary-powered sportscar will feature a dual-fuel arrangement, being capable of running on both gasoline and hydrogen gas. If these rumors are accurate, we can expect Mazda's first production hydrogen car to hit the roads in 2012 and revert back to a standard 2-door body style. The current RX-8 uses a set of reverse-hinged doors just aft of the normal front portals. We'll see.

Hydrogen works wonderfully in all ice engines, not just rotary. All the complications in that domain are there because secret services of c.i.a, kgb, europe coalition, u.s.a military, associated press, gm, world banks, james bond 007, u.s.a farmers, madscientists, hollywood artists, big oil, world state employees and journalists, all these folks are studying hydrogen right now and are at the same time rejecting all they discovers because they didn't find any real problems with it.
They got a nerve depression when they discovered that hydrogen gas can be made free with water and that it's a non-polluting process to move cars and trucks forward with low-cost to adapt this technology to existing cars and trucks.

Wake up, gorr. Your imaginary conspiracies are just that.
OPEC is a real conspiracy, openly proclaimed.
Hydrogen can't be electrolyzed "free" from water - it takes an enormous energy input. That's not a CIA conspiracy, it's a law of chemistry and physics. Take it up with God if you're a believer.

Hydrogen just plain and simple sucks as a fuel for an internal combustion engine. External combustion is another story altogether. Hydrogen may be the most abundant substance in the universe but it isn't naturally plentiful anywhere where we can get it. We need to extract it from something else whether that be water or something else. This isn't easy or efficient. Then when you get past that it makes half the power of anything else viable. It's just crap and has no future. At least not within any of our lifetimes.
Now saying that, hydrogen does work better in a rotary than other engines. Why? A rotary does not have to worry about combusting it accidentally during the intake stroke from heat left over in the combustion chamber. Remember a piston engine has it's combustion, and all associated heat, located in one place. Heat can remain in the valves, head, and any number of other places that can potentially ignite an unstable fuel such as hydrogen as it enters the engine. It's not saying it always happens but it can and the can makes it a problem.
A rotary doesn't suffer from this problem as the intake is located on the far side of the engine from all associated heat at the point of combustion. It's really quite simple to see why it's a better engine for hydrogen or any other "gaseous fuel" for that matter. It is far more likely to combust where you want it.

I said that hydrogen gas can be obtained free from water, is that clear ??

In the first vid hydrogen is most likely generated through chemical reaction between water and active metal like sodium. If you didn't skip elementary chemistry you would know that.
I'm pretty sure that mining and refining of metals is very energy intensive process.
Please do us a favor, go back to elementary school and finish your education.

There are lots of metals that will react with water to form H2 and a metal oxide. Even iron will produce H2, though rather slowly, as it rusts.
Dingle of the Phillipines has copied the Stan Meyers "water car" fraud, his car runs on regular fuels, the "electrolysis cell" is just there for show. Just like Meyers, he is looking for "investors" and "dealers" but won't actually provide the product he is selling.

I said that water can be obtained clear from free, is that hydrogen ??
In the first video it said free . They don't say metal and if you're looking to trade metal as a job for all your futur life on earth, then sell the metal to who needs it. There is lot of metal to be mined and sold for every kind of products. It's not because an invention in particular don't need natural ressources that this invention should be prohibited.

Hydrogen isn't water in the same way that Wood isn't ashes.
Water is the "ashes" of burning hydrogen, and it takes considerable energy to "un-burn" water back into 2 parts H2 and 1 part O2.
Sorry, but Meyers (convicted of fraud) and Dingle are lying to you when they pretend you can "un-burn" water with far less energy than you get from burning that H2.

To whom can read between the lines. These naysayer of everything are telling the truth about their personnal past. Not directly and by adopting false identities, but if you read carrefully, then you can have a feel for them and what they fear, what they done, what interrest them, etc.
In this exemple, one guy admit having burn ' believers' in the past because they were afraid of living in skin corpes for eternity and they don't get used in their entire life to skin charm and reproductive process. Then we have the secret of the believers having be eaten by lions in old rome, millions of people having been burn in europe in the middle age by inquisition task force, world trade center, dead camp in the second world war, so on...
He fear they the ole burned people will need extra energy to overcome this and get a revenge, that's all. They are dead in their head and are proposing this reality to everyone.
Even a film in internet with real image and sound and real people is naysayed but strangelly it give value to that film afterall.

Gorr, can you tell me which religious leader you are following? I want to stay as far away as possible.
Oh, and if your "Glorious Leader" offers you kool-aid or a trip on a spaceship hiding behind a nearby comet, politely decline the offer, or you'll end up a real dead "skin corpse". (See "Jonestown" and "Heavens-gate cult")

Er, no, I think if Gorr's leader offers koolaid, or a trip on a ship, the offer should definately be taken up...
also in regards to the hydrogen argument, i beleive some recent discovery/breakthru, i heard of somewhere, will help, still not free, and still at an obvious energy cost, but notably less energy / $ required to produce H2, cant remember where/when, look it up i guess....

God, I hope not.
Hydrogen leaks worse than exhaust for pollution ATM + technology less proven than even the rotary + it's a goddamn race-ready sports car, not an economy sedan = we don't need to destroy the lineage of the RX-7 with a potentially disastrous hydrogen cell.
If Carney's right, it's the same problem with electric cars - creates too much pollution to create the fuel in comparison to gasoline. Oh, and electric motors weigh over 9000 pounds.
Diesel is the fuel of the future. As for the pollution, we'll probably be running carbon filters in addition to our catalytic converters in the future.
