Nanoparticles Could Make Hydrogen Cheaper Than Gasoline 442
Roland Piquepaille writes "According to EE Times, a California-based company called QuantumSphere has developed nanoparticles that could make hydrogen cheaper than gasoline. The company says its reactive catalytic nanoparticle coatings can boost the efficiency of electrolysis (the technique that generates hydrogen from water) to 85% today, exceeding the Department of Energy's goal for 2010 by 10%. The company says its process could be improved to reach an efficiency of 96% in a few years. The most interesting part of the story is that the existing gas stations would not need to be modified to distribute hydrogen. With these nanoparticle coatings, car owners could make their own hydrogen, either in their garage or even when driving."

You misunderstand the meaning of "synthetic" oils. They are synthetic in that they are lab-created from stock ingredients to specific and precise formulations, rather than refined directly from crude oil as in a "traditional" oil. That said, the base stock chemicals still come from petroleum, such as an alkene, an ester, or the newer gas-to-liquid where a light-chain gas fraction is separated, hydrated and catalyticaly converted into a desired liquid.
The advantages of synthetic oils are that you can pretty much completely eliminate undesirable compounds, and you can precisely tailor chemical ratios to achieve a desired behavior. Neither of those are possible/feasible with distillation, since a "bad" compound might have a boiling point within a hair-fraction of a degree of something "good", and a lot of different "good-for-different-purposes" chemicals have very close boiling points as well.

Answer: They're not an OIL company, they're an ENERGY company. They understand this. If something else displaces oil they don't want it to displace THEM. Instead they want a piece of the new thing, too. They're just as happy to invest in developing and manufacturing solar panels and pocket some money when you buy them (or to run solar farms and sell electricity) as they are to invest it in exploring for oil and taking a cut when you buy that (while passing on the bulk to the people sitting on the land over the oil.) And meanwhile it gives them a power source to run some of their own remote equipment. B-)
There's a lot of money in oil. But there's little margin. Virtually all of it goes to pay for the crude feedstock and the infrastructure to extract, refine, and ship it. (That's OK. Like groceries, oil goes from purchased raw material to sold product in a short time. So the company's money gets cycled through the buy/refine/sell process several times a year, making a small profit margin add up to a good rate of return on investment.)
As with solar panels, energy companies have more incentive to develop new processes than to buy and sit on them. Because they won't be the ONLY processes to achieve results. So if company A buys process a to develop product whiz-bang, then sits on it, company B eats their lunch when it buys and develops process b and owns the market as whiz-bang displaces refined oil.

if too many people switch to hydrogen cars, then oil becomes worthless, because coal can be mined cheaper, etc.
not to mention that wood can be burned as efficiently as coal, although at a slightly higher price, but environmentally speaking, parts of Wisconsin could become a 'bio renewable' energy source and then only the hydrogen has to be transported, or even the electricity to make the hydrogen gets transported.
so this has a really big impact. it's easier and cheaper to make and transport electricity than it is to ship oil and gas, and if at the end of the line it's 97% efficient, then making hydrogen at the point of sale could be massively cheaper than the kind of distribution network needed to sell oil.
i doubt hydrogen fuel cells will ever be truly viable, but hydrogen combustion isn't that hard to do with modern engine design either. it's so easy that gas ICEs can be converted to hydrogen ICEs for little cost (this is why over a million vehicles ran on woodgas in world war II, when oil supplies fell far short of demand.) shipping hydrogen around and storing it in mass quantities is more expensive than 'making it at the pump' from ordinary filtered water, so this technology may finally make a hydrogen economy viable, and thus render oil obsolete.
and the biggest plus side is producing 'hot' water as the output exhaust, puts fresh water back into the freshwater cycle as humidity, that will eventually become rain, produced from cars then much of that humidity will wind up precipitating on land, as it does with forests. hydrogen combustion could restore part of the freshwater cycle that clearing forests for cropland has removed, so it's twice as good for the environment, since it produces less emissions and produces humidity. although in some regions it will be cheaper to ship hydrogen rather than produce it at the pump, and in some areas it may be necessary to desalinate water, or use 'waste water' from sewer systems.
of course, oil can still be burned to make electricity, and with increased demand for electricity driven by a hydrogen economy they would likely sell a lot of oil for use in creating electricity, however this is sold much cheaper than gasoline and doesn't use the same refining process as gasoline (there is no need to 'crack' the chemicals to get shorter chains when you're burning oil for electricity, and not making gasoline) so the oil industry will loose many jobs, and the oil wells that are currently being tapped will wind up selling far below where they were expected to sell, causing oil exploration to basically stop completely, and eventually many generations from now bio-fuels will become the cheapest form of energy when fossil fuels run out.

Now, take a milk jug, a large cork with a hole in it, and a glass tube with a tapered end. Cut the bottom completely off the milk jug. put the tube in the hole in the cork and cap the jar with it (mare sure it's a tight fit). Place tape over the small remaining hole to prevent gas leaking out.
Now, mount the apparatus tube side up (open bottom of jug pointing at floor) from a clamp on a pole (so it will stay that way without you holding it, trust me, you don't want to be holding it!). You should in essence now have a big bowl, suspended upside down, with a small hole in the top. Open the valve on your H2 container and allow the gas to rise up into the bowl (since it's lighter than air, it will fill it and stay there).
Now, take the tape off the tube so that the H2 will start to rise through it. Light the escaping gas with a match (I suggest from as much distance as you can give it to be safe, a match held from a 3-6 foot long handle or longer, just in case this goes off before expected).
Now, what you will have is a small flame coming out of the glass tube. This flame operates like a torch because the vapor pressure from the H2 trying to go up is more than the air tring to go down and gas only flows one way. You should have a very feint blue flame here. This may burn for 15-90 seconds depending on how well the milk jug got filled, and how small your tube is.
After a minute or so, the H2 remaining in the milk jug will start to lessen, and air pressure above and below the tank will eventually equallize, allowing the flame to go down the tube and contact the remaning, ambient room pressure gas in the milk jug. BOOM!
trust me: If you do this indoors, say in a large classroom lab in a school, you'll have security personell and panicked people running from all directions, since this small amount of H2 gas, trapped in a gallon of airspace at static room pressure will generate a fireball that will shake the windows and ring eardrumbs.

Likewise, we've already come up with a few ways to make bio-plastics (some of them even being economically on-par with petroleum-based plastics). I imagine that more alternative materials will surface as time goes on. Conserving and reusing plastics will take some getting used to, but also won't be a huge issue.
Perhaps we might even be able to do away with the "disposable" consumer culture we live in.

We still need energy to MAKE that Hydrogen. Whether it is done at big plants or from electricity in your house, the energy has to come from somewhere. Big oil will still be drilling to supply the engines the generate electricity that comes to your house that makes Hydrogen. Coal and Oil will still be the big sources of energy for a long time.

That's a completely baffling statement to me. So baffling as to trigger my BS detector.
Presumably the point of producing it in the car is to avoid the need to store the gaseous hydrogen. But electrolysing hydrogen requires energy--the hydrogen is not a source of energy so much as it is a storage medium for energy. So where would that energy come from?
From a gasoline-powered generator in your car? Or what?
Sounds like a smooth-talking snake-oil salesman who's answer to everything is "yes, we've solved that problem too."

The commentary on the original article, though, links to the the press release [qsinano.com] which clarifies it. The application they're talking about is a plug-in rechargable car. When you're at home, you plug it in, the car electrolyzes water to produce hydrogen, and then, when you unplug it, you run the car on the hydrogen.
The application, then, doesn't address the problem of how to store hydrogen, only the problem of how to produce it.

Now, why would you want to do this instead of simply use the battery for electric drive? Well, one could make the argument that converting standard hyrdocarbon fuels from the pump to hydrogen ON the vehicle eliminates the need for fueling infrastructure change which is a MAJOR barrier to the widespread adoption of a "hydrogen economy". With hydrogen on the vehicle it could be used to power a fuel cell for electric drive or some other combustion engine such as BMW's multi-fuel hydrogen car. "Just add power" (solar? plug-in? other?) and if it's all done just right, what you get is more efficient fuel combustion with lower emissions than you would have gotten from burning the gasoline straight. That model I think could be viewed as a "stepping stone" towards conversion much like today's hybrid cars are regarded as a stepping stone towards all electric.

Why post articles like this? It's just an advertisement for a non-existent technology. There are tons of crap like this out there, why single this one out?
Let us know when someone actually develops something real and working, then it might be news.
TFA says it is working, and at 85% efficiency. They speculate that by 2010 they could get up to 96% efficiency. Also TFA says they partnered with one of the major battery manufacturers and will be releasing a product later this year that uses their technology.

"Big oil" are energy companies. They really don't give a rats ass if they sell you oil or nuclear fusion. "You" arn't even their real customer, but rather the power plants are.
