Pressure swing absorption is the cheapest approach to making pure o2, and it's not very efficent...but I know little about fuel cells, and was unaware they called for pure oxygen. As a glassblower, I know a little about producing oxygen, and some of the problems with hydrogen. Being the smallest possible molecule, it leaks like a SOB, degrades rubber, and makes metal brittle. I think using liquid nitrogen as an energy carrier is much more promising. Admittedly only about an 1/8th the energy density of gasoline, its main advantage is in having zero emissions. My first thread on the forum was about this idea:
http://www.motoredbikes.com/showthr...ustics-liquid-nitrogen-and-rotary-vane-motors
they prefer pure oxygen, pure fuels, mainly because of that catalyst! platinum, coming in contact with lead and certain other metals...big no no! thats where the RD is directed...reducing that requirement, that danger... you have to pump air through them somehow, and when the atmosphere is only approx 16% oxy... a lot of wastage.
as a comparison...oxy acetylene cutting...even with only 96% oxy, the cutting rate is almost halved, over pure oxy! something like that, anyway...been a while since i saw the chart. but at a certain (fairly high) percentage, it just stops working!
what sort of glass blowing? jewellery ornamentation type or laboratory glassware type? i used to love doing that stuff
(the following is just me having a rant....its not directed at anyone in particular...just venting
its all related from where im standing)
yeah, tis a silly idea
though a fuel cell kit can be bought on ebay for a few dollars... they are fun to play with
does the energy required to make the hydrogen and oxygen ever become available through the subsequent re-combination? nope. some vanishes. and entropy increases. entropy...when all energy levels have reached equilibrium. no transfer possible. stasis. dead.
## 1932, Charles H. Garrett, USA, the first to run a Internal Combustion Engine car with water, using water electrolysis, and obtaining a patent, 70 years ago… :United States Patent, 2,006,676, Electrolytic Carburetor, Texas, 1932, Serial No. 620,364.
just cus you can draw something, and get a patent on it, doesnt mean it WORKS!
at least, mainstream science and all these shell and exxon funded studies tell us it doesnt work... im yet to (personally) see anyone actually have a go at making one of these things... i know when i tried pumping some hydrogen into a running dirtbike, it promptly needed a new head gasket
thats as far as ive gone, myself...one can only dream! (for more money to experiment with these crazy ideas)
why wouldnt they teach us about magnetics in highschool?
what is gravity, exactly? really? time? what about that one?
im getting esotoric now
and why, exactly, is "naescent" (newly created) hydrogen so much more reactive than old hydrogen from a bottle? that one is well known in chemistry. i think its a monatomic thing... 2xH1 rather than 1xH2. dont have to split the molecule before combining with the other element in the reaction. saves some energy.
ever heard of atomic hydrogen welding? it was a precursor to the TIG, was an evolution of the carbon arc and the oxy hydrogen welding. basically, an arc is struck between two tungsten elsctrodes, and a stream of hydrogen is directed through the arc. this does some weird thing and somehow transfers the energy of the arc through the hydrogen, that is being split into plain hydrogen atoms... as described in my comprehensive 1942 lincoln welding handbook
it was quite popular at the time, mostly for what tig is used for now! because, back then...all tig was scratch start...meaning contaminated welds...
( i always saw the transfer of hydrogen through another material as being almost like the flow of electricity in a cable.... electron fills a convenient hole, and one pops out the other side! all it needs is a lil protonic companion, and there you are...hydrogen...thats just the way i see it, and is probably wrong wrong wrong but nevermind, i like it!)
then theres this idea...

right down near the bottom... the high temperature part, and this bit mainly...
"Molten salt storage[edit]
The 150 MW Andasol solar power station is a commercial parabolic trough solar thermal power plant, located in Spain. The Andasol plant uses tanks of molten salt to store solar energy so that it can continue generating electricity even when the sun isn't shining.[66]
A variety of fluids have been tested to transport the sun's heat, including water, air, oil, and sodium, but Rockwell International[67] selected molten salt as best.[68] Molten salt is used in solar power tower systems because it is liquid at atmospheric pressure, provides a low-cost medium to store thermal energy, its operating temperatures are compatible with today's steam turbines, and it is non-flammable and nontoxic. Molten salt is used in the chemical and metals industries to transport heat, so industry has experience with it.
The first commercial molten salt mixture was a common form of saltpeter, 60% sodium nitrate and 40% potassium nitrate. Saltpeter melts at 220 °C (430 °F) and is kept liquid at 290 °C (550 °F) in an insulated storage tank. Calcium nitrate can reduce the melting point to 131°C, permitting more energy to be extracted before the salt freezes. There are now several technical calcium nitrate grades stable at more than 500°C.
This solar power system can generate power in cloudy weather or at night using the heat in the tank of hot salt. The tanks are insulated, able to store heat for a week. Tanks that power a 100-megawatt turbine for four hours would be about 9 m (30 ft) tall and 24 m (80 ft) in diameter.
The Andasol power plant in Spain is the first commercial solar thermal power plant using molten salt for heat storage and nighttime generation. It came on line March 2009.[69] On July 4, 2011, a company in Spain celebrated an historic moment for the solar industry: Torresol’s 19.9 MW concentrating solar power plant became the first ever to generate uninterrupted electricity for 24 hours straight, using a molten salt heat storage.[70]"
just think... a small fresnel lens (only a few metres across) supplying ALL the power for your house? no fuel at all? sure, implementation is tricky, but storing a highly flammable liquid is pretty hairy in itself... and having hi tension powerlines crackling away over, seemingly, every school in AU..
its been done. the system is available, but dont expect a rebate for installing it, just yet.
go look up daltons law, and just contempate it as an air conditioner...heat one part up...to cool one part down. it has been done. gas fired refrigerators, ahem? and the aircon idea. try and BUY one of them, but
instead of storing electricity, store HEAT. a plug in heat exchanger on your car... just sucks some of the juice from your main storage tank buried in the ground... no vapours, no carcinogenics... exhaust fumes..cat convertors...
its very easy to store heat. just add more insulation! generate the power as required...
you would be amazed how long it takes 10kg of table salt to cool down from 900C, just sitting on a bench!
like water..salt has a lot of LATENT heat. specific heat is what you measure in degrees. latent is what you measure in WATTS/mass
all batteries go flat, self discharge, at a rate determined by chemistry type. heat will eventually escape too. but batteries degrade... salt doesnt. the tank might corrode eventually, but otherwise, it will store just as much energy in ten years as it did the day it was installed.
could even make some type of "heat pack" that you swap at the garage/ service station... minutarised, as a battery pack, some type of thermoelectric coupling or a sterling generator? plenty of ways to tackle it!
but, like CNG...implementing it, getting it out there in a big enough way to be viable. electric cars....pfft, old hat...what did they use in the early 20th century?
windpower? the dutch do it properly. neat lil wind turbines. vertical shafts. us? ours cost more to service and erect than they will EVER produce in their useful lifespan... not to mention the noise of the dam things!
desalination...why, in australia, with all our sunshine, do we NOT have solar powered desalination, like they do in other countries? oh no, just spend a few billion on these great monstrosities that as soon as they were finished...never needed to go into service! all the dams flooded! thankfully, cus who was going to pay the power bill?
what did someone once say? if half our roads (in AU) were turned into heat exchangers and used to generate power...we would be leaving the coal, the CNG, the coal seam gas, the lpg, the petroleum... under ground.
seriously, whos going to implement THAT?
its almost as ludicrous as Teslas dream to transmit power without wires! WHAAAAT?!? how do you make any MONEY MONEY MONEY out of that?
im a miserable *****
the worlds screwed and the sooner the human race wipes itself out, the better
its all about money money money, and whats it done? you cant just "live off the land", you own land...you gotta pay for it! you have to make money, just to give to some beauracrat, so you can retain your small parcel of dirt.
small towns are dying as people leave in swarms for the big smoke with lots and lots of money! the shops close. the few remaining farmers...where do they go to get fuel? to get food that they cant grow? transport what they do produce? get bitten by a snake or get appendicitis? they give up, sell the land, and head off for town too. who buys the land, nice and cheap? some other country, because theyve destroyed all their farmland already.
as for all this "west side" nonsense...stuff ya gangsta cr4p where it belongs... kids today... pfft! as one comedian recently said "um...your in freaking lismore, d1ckh34d!...i dont see a west side...what you rapping about? how hard life is on the streets of lismore? yeah, rapping it up in lismore....good one
"
we cant all be lawyers but. or sell real estate... sooner or later, somethings gotta give!
lol, i should get a PHD in philosophy...
in conclusion, we are SURROUNDED by power, just waiting to be tapped into. all that holds us back as humanity, progressing as a species, is these multi billion dollar profit earning corporations. the ceo doesnt care. he can afford nice air filtration units and cancer treatments. as long as he has lots and lots and LOTS of money!!!!
(hes still gunna wind up in a casket one day, and be worm food just like the rest of earthly creation)
so dont gimme no cr4p about how reducing a lil bit of ring friction will suddenly make the world a magical happy place for all. it wont.
all it does is continue our dependency on a dwindling resource.
^^^^far out, i feel like deleting all that nonsense!^^^^
i have the longest freaking posts... im sort of embarrassed about it... but it all needs to be said or ill EXPLODE!
