	<title>Piezo Crystals Harness Sound To Generate Hydrogen</title>

	<htmltext>MikeChino writes <i>"Scientists at the University of Wisconsin-Madison have discovered that a mix of <a href="http://www.inhabitat.com/2010/03/17/new-piezo-crystals-harness-sound-waves-to-generate-hydrogen-fuel/">zinc oxide crystals, water, and noise pollution</a> can efficiently produce hydrogen without the need for a dirty catalyst like oil. To generate the clean hydrogen, researchers produced a new type of zinc oxide crystals that absorb vibrations when placed in water. The vibrations cause the crystals to develop areas with strong positive and negative charges &mdash; a reaction that rips the surrounding water molecules and releases hydrogen and oxygen. The mechanism, dubbed the piezoelectrochemical effect, converts 18\% of energy from vibrations into hydrogen gas (compared to 10\% from conventional piezoelectric materials), and since any vibration can produce the effect, the system could one day be used to generate power from anything that produces noise &mdash; cars whizzing by on the highway, crashing waves in the ocean, or planes landing at an airport."</i></htmltext>

	<htmltext>I could be wrong, but I thought sound waves moving through air carried a surprisingly small amount of energy. When it comes with tangible vibrations, waves so strong they pulsed through the ground and other solids to reach you, the net effect might create significant amounts of energy, but just loud noises probably wouldn't give you much in the energy department, especially at 18\% yield.</htmltext>

<sentencetext>I'm a bottom-dweller and I fuckin' like it that way.
I don't want to be forced to read all of your high-minded, high-rated, hyperbolic waxing on bullshit you know nothing about and think you're making some sort of impact on the universe with because you had a stupid 2-paragraph, uninformed, heavily biased essay replete with missing words and other typographical errors get modded up by yet another set of heavily-biased clueless assholes.I want to be down here with my brethren and view only our postings, as He intended things to be.
Of course, that doesn't play well in the minds of the arrogant site owners who think that people only want to read what they want to read, so I'm left sifting through all the fuckin' bullshit that you elites puke out in ridiculous volumes.Give me the option to have -1 given emphasis and leave me to post as much as I fuckin' like down here, you google-dick-sucking fucktards.</sentencetext>

	<htmltext>You know, this sounds (npi) neat, but the revolution is I think in how much energy they could harvest with this technique.  It might be easier, and not require the water, BTW, or at least, not require the water to be consumed (by breaking into H2 and O) by using a mechanical amplifier/impedance matcher akin to the way the inner ear works, and then mechanically rectifying THAT, to produce electrical power in a more conventional fashion.

	<htmltext><p>The truth is that we could use electricity much more efficiently but we don't because energy is still relatively cheap. Why don't we  see zero emmission, low energy cars? Becasue it's BIG business and there is already a heavy investment in OLD technologies (petrol and diesel engines).

How many people worry about the energy their laptop / TV actually uses compared to the functionality?</p><p>Hydrogen is surely the obvious future for CLEAN energy (WATER = H20) and as far as I know if you use an electroliser or fuel cell, rather than thinking of combustion analogies, you will see this is a technology that seems to be obvious but it has been suppressed due to commerical interests (making the most money from what you spend). I guess we'll never see the clean hydrogen economy untill the infrastructures are in place (and the H2 cars are cheaper). As people start to care, so does goverment and then business waits for help with the investment (to encourage the change). Companies won't change if it is going to put them at a commercial dissadvantage!</p><p>Only now do we start to see cards powered by electric motors and fuel cells but these cost way too much (as they are not in mass production). They have just been for publicity. So I guess the car's will change eventually, when they've finished the petrol reserves on the planet and made energy hugely expensive?</p><p>On a green point, electric car's with a ton of batteries are a joke as the batteries are toxic and also the weight casues additional mechanical wear.</p></htmltext>

Why do n't we see zero emmission , low energy cars ?
Becasue it 's BIG business and there is already a heavy investment in OLD technologies ( petrol and diesel engines ) .
Also it 's really not worth the public getting worried untill energy gets more expensive .
How many people worry about the energy their laptop / TV actually uses compared to the functionality ? Hydrogen is surely the obvious future for CLEAN energy ( WATER = H20 ) and as far as I know if you use an electroliser or fuel cell , rather than thinking of combustion analogies , you will see this is a technology that seems to be obvious but it has been suppressed due to commerical interests ( making the most money from what you spend ) .
I guess we 'll never see the clean hydrogen economy untill the infrastructures are in place ( and the H2 cars are cheaper ) .
As people start to care , so does goverment and then business waits for help with the investment ( to encourage the change ) .
Companies wo n't change if it is going to put them at a commercial dissadvantage ! Only now do we start to see cards powered by electric motors and fuel cells but these cost way too much ( as they are not in mass production ) .
They have just been for publicity .
So I guess the car 's will change eventually , when they 've finished the petrol reserves on the planet and made energy hugely expensive ? On a green point , electric car 's with a ton of batteries are a joke as the batteries are toxic and also the weight casues additional mechanical wear .</tokentext>
<sentencetext>The truth is that we could use electricity much more efficiently but we don't because energy is still relatively cheap.
