Compressing hydrogen? Answered

I have a hydrogen generator and use the gas as i make it at the moment. I want to try compressing it, the issue is the gas is really a combination of pure oxygen and hydrogen in the perfect explosive mix. If i have flame aresters on all my pipes and have it well earthed as well as not using steel parts in the compressor so there is no chance of static or sparks from steel, will it be relatively safe to try compressing this into a cylinder? or am i insane to try this???

Visible Gas? Answered

I wan't to fill a chamber with hydrogen, have a chamber of the same size linked with it, with a heavy visible gas in it, then as I pump out the hydrogen the heavy gas displaces it and I can see when I need to stop pumping and refill with hydrogen.  What gas can I use,  I know just about any visible gas will work because hydrogen is the lightest, but it would be nice if it was heavier than average air so I could allow air to flow into my heavy gas chamber to displace it.  Or can I just die the air with some kind of smoke from my smoke machine. Yes hydrogen is extremely explosive, so this would be on a very, very small scale with hopefully 0 oxygen.

How to produce 14,000 cubic feet of hydrogen? Answered

Okay, here is the deal. Me and a friend where thinking about filling two weather balloons( http://www.ebay.com/itm/GIANT-Weather-Balloon-Meteorological-Military-8-Dia-/330626487344?pt=LH_DefaultDomain_0&hash=item4cfadfd430) with a lifting gas, sending it up with a camera and gps-cellphone. Now, we have everything else figured out but how to get hydrogen, as it is the lightest gas. Is there any way to produce those quantities of hydrogen within a 6-36 hours? I figure I'd ask here because there are quite a few hydrogen powered vehicles here.

Pulse jet cogeneration either hydrogen generator or steam turbine?

I wanted to make a pulse jet and use peltiers to generate electricity to create hydrogen that will be added to the pulse jet. That or i'd run water around the metal of the pulse jet to cool it down and produce steam that could drive a turbine. Give me suggestions and any flaws in my idea. Thanks

which valve to use for storing gas in bottles?

I need to store gases(mainly hydrogen, generated from electrolysis)  in a bottle. I was thinking of getting a bicycle valve and attaching it to the bottle. The problem is I cannot find a bicycle valve anywhere online. Moreover, when a bicycle valve is opened the inside gas leaks out. Is their anyway of storing a gas in a (soda or soft drink) bottle? Which air valve should I use?

I volunteer to gather eyewitness info on water into hydrogen.

I'm a beginning engineering student and my dad is also an engineer. He is pretty skeptical and he recently told me of someone he knows who is using electrolysis to get better gas mileage in a Toyota pickup. I'm not sure, but it seems he is using secondary voltage to power the split and then burning it. He claims 60 mpg. If you guys would like to give me a series of questions/tests, I would love to go to my hometown and ask/perform them, then report back. Any takers?

Paper two stroke hydrogen engine

 Ok so I have this crazy idea to make a two stroke engine out of paper that runs on hydrogen and well ive allready built part of it just the piston head and cylider and stuff but if i lined the inside of the cylinder with tin foil would that be enoth to keep the paper from burning? and so ya anyways the engine of i have made allready is very sturdy each peace is 10 sheets of paper or more compressed for over 24 hours  now the compression im not two worried about because its more of the sheer pop of the explosion that will push the piston down well i guess thats how it is anyways but if the gas ignites anyways with oxygen why have compression  for this anyways because the explosion is going to be soooo small anyways that it wont really matter much.  the overall size of the engine is about almost 2" tall by about 1" wide on the widest part the bottom . So um I know by now im classified as "CRAZy" but that asside can i get some opinions and ideas plz. thanks MRN

What keeps diy water torches from "back firing" ? Answered

I wish to make one using electrolysis. Electricity breaks the water into hydrogen and oxygen, then the gas then goes through a bubbler and then to the torch. Can water torches backfire because of the oxygen in the HHO gas?

Hydrogen for renewable energy storage- total system efficiency?

This is a question that has been bugging me for some time, especially since the questions about methanol synthesis revived my interest in energy storage. Say I have a wind turbine or solar panel or whatever, that produces 1000 Wh per day.  If I use that electricity to electrolyse water, store the generated hydrogen at roughly atmospheric pressure in an upside-down water butt or a big gas-tight bag in my shed (don't worry, I'm not going to actually do this) and then feed it into a generator converted to run on H2, what percentage of that initial energy input would I get back out?  20%?  5%? 1%? The follow-up questions to this are a) How does that compare against a battery bank? What about a similar DIY-style pumped water storage system? b) What one component of the system should be improved to raise the overall system efficiency? Electrolyser, storage, generator? c) Are there any other DIY-friendly methods for storing intermittently generated electricity that I'm not thinking of? And, I suppose, d) Does doing this and providing 5-10x your overall power requirements in wind turbines work out cheaper than spending thousands on batteries?

Liquefaction of gases?

After separating Hydrogen and Oxygen from water (through electrolysis), how should I go about Liquefying and storing these gases? One method of liquefaction that I've come across is here ( http://1.bp.blogspot.com/_OGu0H7TFUno/SLI8QOVkemI/AAAAAAAAABk/Y0fenD3BvbE/s1600-h/ln2_generator.jpg ), and another is here (http://www.gizmology.net/liquid_air.htm) Both of these include compression, but the latter cools the gas by expanding the room-temperature gas, and therefore cooling it. Which method is best? Are there any others?

HHO powered car

One of my friends asked for my help for a project for his school expo. He wants to run a car on water and I have told him not to be too optimistic. when I googled it all I found was that it was not possible(as of now), but no other detail. I did stumble upon an old episode of myth busters in which they came to the conclusion that a car can run on hydrogen, but they were unable to provide enough hydrogen from their electrolysis setup, however, I noticed that the HHO generator created by king of random produces way more gas then theirs. so I wanted to know your opinion and knowledge on this matter and whether this can work or not.

Could one re-purpose a respirator to prevent noxious fumes from escaping?

Hi there! I have had this idea in my head for some time, especially now that I am looking into metal etching. But I am an apartment dweller, with a cat. Now, I know that this is pretty broad. So I will give a specific example: if I build this https://www.instructables.com/id/Electrolytic-Etcher/. Can I build also a tank using say, these acid-gas cartridges http://www.mcmaster.com/#5834t66/=walor0 in-line with the exhaust of a vent system to clean out the chlorine? Would this work? Would it be safe? Would it allow the relatively slow out-gas of hydrogen to disperse, or would it concentrate it? Any thoughts at all? Thanks! Ernest.

What is the Best Way for a Do-It-Yourselfer to make a few good Diamonds? Can I just Heat some Methane and add Water? Answered

I'm looking for practical ideas and expertise with making such things. I have a Wood Furnace that gets hotter than 1000 F and a tiny Camp Stove burning Pellets.  I have Propane for the Carbon. Water could be used to a little Hydrogen or Oxygen. I would like to make a 1 carat Round Brilliant Cut perfect Diamond and a 1 1/2 inch Maltese Cross looking Diamond as perfect as possible. I believe I could make the 1 carat Diamond in a 1/2 inch tube using a low quality Diamond as the substrate and target at the end of it. I would have to activate the gas mix moving through the tube just before the substrate. Do I need a Microwave or UltraViolet Light or something? I need some Know-How and Inspiration.
