They've been published so they'll be fine.

Hydrocrackers are common. This is just a new and much better catalyst. No one's going to "off" the scientists.

This is just an opportunity for new industry.

Strangely enough, there is a dull, boring business story on the front page of today's South China Morning Post -

'Sichuan firm buying deposits of key metal
A privately owned Chinese company is poised to take control of two of the world's biggest deposits of a key metal. Sichuan Hanlong, little known outside the mainland is building up its reserves of molybdenum, which is used for hardening steel, in nuclear power plants and for missiles and aircraft parts.'

FWIW

Whoa molly.

Chinese will practically own this new catalyst then.

Guess who has figured it out?

Hydrogen will not be economically viable within the next 10 years at least! All these hidrogen stories are science fiction!!

That´s bittersweet - like having your wisdom tooth removed by a topless nurse.

ScienceDaily (May 1, 2010) — Hydrogen would command a key role in future renewable energy technologies, experts agree, if a relatively cheap, efficient and carbon-neutral means of producing it can be developed. An important step towards this elusive goal has been taken by a team of researchers with the U.S. Department of Energy's (DOE) Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California, Berkeley. The team has discovered an inexpensive metal catalyst that can effectively generate hydrogen gas from water.

"Our new proton reduction catalyst is based on a molybdenum-oxo metal complex that is about 70 times cheaper than platinum, today's most widely used metal catalyst for splitting the water molecule," said Hemamala Karunadasa, one of the co-discoverers of this complex. "In addition, our catalyst does not require organic additives, and can operate in neutral water, even if it is dirty, and can operate in sea water, the most abundant source of hydrogen on earth and a natural electrolyte. These qualities make our catalyst ideal for renewable energy and sustainable chemistry."

Karunadasa holds joint appointments with Berkeley Lab's Chemical Sciences Division and UC Berkeley's Chemistry Department. She is the lead author of a paper describing this work that appears in the April 29, 2010 issue of the journal Nature, titled "A molecular molybdenum-oxo catalyst for generating hydrogen from water." Co-authors of this paper were Christopher Chang and Jeffrey Long, who also hold joint appointments with Berkeley Lab and UC Berkeley. Chang, in addition, is also an investigator with the Howard Hughes Medical Institute (HHMI).

Hydrogen gas, whether combusted or used in fuel cells to generate electricity, emits only water vapor as an exhaust product, which is why this nation would already be rolling towards a hydrogen economy if only there were hydrogen wells to tap. However, hydrogen gas does not occur naturally and has to be produced. Most of the hydrogen gas in the United States today comes from natural gas, a fossil fuel. While inexpensive, this technique adds huge volumes of carbon emissions to the atmosphere. Hydrogen can also be produced through the electrolysis of water -- using electricity to split molecules of water into molecules of hydrogen and oxygen. This is an environmentally clean and sustainable method of production -- especially if the electricity is generated via a renewable technology such as solar or wind -- but requires a water-splitting catalyst.

Nature has developed extremely efficient water-splitting enzymes -- called hydrogenases -- for use by plants during photosynthesis, however, these enzymes are highly unstable and easily deactivated when removed from their native environment. Human activities demand a stable metal catalyst that can operate under non-biological settings.

Metal catalysts are commercially available, but they are low valence precious metals whose high costs make their widespread use prohibitive. For example, platinum, the best of them, costs some $2,000 an ounce.

"The basic scientific challenge has been to create earth-abundant molecular systems that produce hydrogen from water with high catalytic activity and stability," Chang says. "We believe our discovery of a molecular molybdenum-oxo catalyst for generating hydrogen from water without the use of additional acids or organic co-solvents establishes a new chemical paradigm for creating reduction catalysts that are highly active and robust in aqueous media."

The molybdenum-oxo complex that Karunadasa, Chang and Long discovered is a high valence metal with the chemical name of (PY5Me2)Mo-oxo. In their studies, the research team found that this complex catalyzes the generation of hydrogen from neutral buffered water or even sea water with a turnover frequency of 2.4 moles of hydrogen per mole of catalyst per second.

Long says, "This metal-oxo complex represents a distinct molecular motif for reduction catalysis that has high activity and stability in water. We are now focused on modifying the PY5Me ligand portion of the complex and investigating other metal complexes based on similar ligand platforms to further facilitate electrical charge-driven as well as light-driven catalytic processes. Our particular emphasis is on chemistry relevant to sustainable energy cycles."

This research was supported in part by the DOE Office of Science through Berkeley Lab's Helios Solar Energy Research Center, and in part by a grant from the National science Foundation.

OMG they will flood the markets with cheap hho gas cars

For autos, reduce the amount of hydrogen but use all the oxygen. Hydrogen will cause engine metal to weaken by about 40,000 miles. It is called hydrogen embrittlement.

How do I power a Generator for electricity and my car with Hydrogen?

1 choice-burn the Hydrogen gas (like a propane engine)
hydrogen burns hotter than gasoline and only gives off water
it also is less dangerous because you are only storing a tank of water in your vehicle
IF the conversion can be done with less power (which is the problem with this)
Fuel cells would be another method

I haven't read the entire thread yet, so if this was already mentioned, just over look it.

But is this fresh water or salt water? Are they creating a fuel that will drain us of life giving water we survive on?
