That is great... we need stuff like that today.
here is some more info on it. It still used electricity though (i believe) witch come from fossil fuel. Great stuff though...
2.2.2.1. Electrolysis of water
High/low heating values and efficiency
The heating value, i.e. the amount of heat energy that can be derived from a fuel by burning it, is rated with a high and a low value. The high value denotes the total energy of the fuel, while the low value takes into consideration that the resulting product gas can be condensed into water, subtracting this condensation energy (latent heat) component. When calculating the efficiency in a fuel cell, the low heating value is normally used, i.e.: electrical energy produced / low heating factor * 100%. In the electrolysis process, the high heating value is usually used.
Water electrolysis is splitting water into hydrogen and oxygen. An electrolyser is a device for electrolysis. Water is subjected to electrical power and the result is hydrogen and oxygen.
2H2O + energy -> 2H2 + O2
This is the opposite reaction of what happens in a fuel cell (see 2.3.1). It is common to classify electrolysers according to the electrolyte it uses. Several cells are connected to achieve the desired capacity, just as with fuel cells. Some common electrolysers are as follows:
Two atmospheric electrolysers, each at 200 Nm3/h

Alkaline electrolysers
In alkaline electrolysers a liquid electrolyte is used ?? typically a 25% potassium hydroxide solution.
Hydrogen production using alkaline electrolysers is long-established in Norway. At Norsk Hydro, industrial water electrolysis of hydrogen for the production of ammonia was carried out from 1928 to 1988.
Norsk Hydro Electrolysers (NHE) is today a leading producer of alkaline electrolysers. Some of NHE??s electrolysers have an efficiency of over 80% (high heating value). Efficiency is an important factor in electrolysis because the use of energy (~4.5 kWh/NM3H2) makes up a significant portion of the costs at an electrolysis plant. (How much will depend on the cost of the electricity. NHE estimates approximately 2/3 of operating expenses as a rule of thumb.) Electrolysers are most effective when running on a low production rate, due to low current density. Optimum economy of operation will depend both on current density, cost of production materials and the demands for H2 production.
NHE and Gesellschaft für Hochleistungwasserelektrolyseure (GHW) have developed a compact electrolysis system that can produce hydrogen equivalent to the energy supply of a standard gasoline station. These electrolysers operate under pressure, and the product is hydrogen under moderate pressure (30 bar).
Another leading manufacturer of electrolysers, Stuart Energy, has also made a small prototype of a home garage electrolyser with compressor and everything else inside a small gray box.
Polymer electrolyte membrane (PEM) electrolysers
Another type of electrolyser utilises polymer membranes as electrolytes (PEM). Much of the heavy technological development which is currently going on in PEM fuel cells can be transferred to the electrolysers, which will probably benefit from the mass production of PEM fuel cells.
Several PEM electrolysers are already being sold today, even though this is relatively new technology compared to alkaline electrolysers. Efficiency factors for PEM electrolysers up to 94% are predicted, but this is only theoretical at this time. Today, the efficiency factors for PEM electrolysers are lower than for the best alkaline electrolysers. PEM electrolysers function very well with renewable energy systems where the amount of electricity varies greatly. Generally speaking, PEM electrolysers are best suited for small plants, especially plants with varying output, while alkaline electrolysers are clearly an advantage in larger systems which are connected to the power grid.
Steam electrolysers
A third type of electrolysers is the so-called steam electrolysers. These use a ceramic ion-conducting electrolyte. Steam electrolysers can reach a very high efficiency factor, but are currently not commercially feasible.[NYTEK 2000] A tubular steam electrolyser, which should also be able to be run in a fuel cell stack (fuel cells connected in a series), are under development at Lawrence Livermore National Laboratory. Another type of steam electrolyser is the German ??Hot Elly?; this system can reach an efficiency of 92%. [NREL 2000]
Thanks for the explanation..and I will view on Google..especially the thrid one since Bong posted on it..I am interested.Quote:

For those of you who don't know what I'm talking about, you can see sections literally explode out in plumes below where the building is actually falling.
and building 7 magically, a modern reinforced steel building, collapses under every hallmark of a controlled demolition on accident that day because of some fires.
Yea, building 7 is actually the most important part of that whole attack... but no one knows about it. How does "debris" from the towers which are hundreds of yards away start fires inside building 7 and then it collapses perfectly in on itself... i smell something fishy.
I will say this about building 7 tho, I have a close friend that was there when building 7 fell, I spoke with him after seeing this video.Quote:

This guy is no expert on demolition mind you, but he has been in construction since the age of 15, allot like myself.
I would hate to think that he would ignore such things, seeing as i was with him in mid town when the towers fell, he went down there to see if he could help.
On a side note I have another good friend that was working very close to them when this all happened, he tells me that he was on site trying to help people when he was ordered away by men, he never said how they were dressed, but he did say that if he didnt leave, he believed they would have shot him.
and bong is a douche... just ignore him... offer him the million dollars that's in my sig as well... it shuts him up pretty fast... or at least that's when he goes back to attacking you and not saying anything about the topic of the post...Quote:

Also, when buildings are set up for demolition, they don't go BOOOOM and explode, the detonations are very muffled and theres an extremely brief flash, then it starts falling in on itself.
