Help making a airship?

Me and one of my friends (we are both second year engineering students) decided to both build an airship and see which performs better. It must be remote controlled and have a volume no larger than 1m^3. I have tried looking for instructables to help me make parts, and seen lots which help with ideas. can you point me in the direction of instructables which explain how to make a remote control for a simple open close valve, making of airtight bags, and general working with balsa wood.

How do I make/find stencils for drawing steampunk airships? Need templates for the different parts of the ship.

I am teaching a steampunk class and want to provide students with stencils for the different parts of airships, i.e., the nose, the tail, the guns or canons, the deck, a mast, etc.  so they can each make their own unique airship by tracing those parts they like.

Producing Hydrogen to Function as a Lift Gas

The short version: I want to make hydrogen to fill model airship envelopes with, because screw helium. Help me make a cheap electrolysis device that can do this in under an hour (ideally), or come up with an even better system for production. My immediate problem is that I need a high-surface electrode that won't fail in a solution of sodium hydroxide.The long version:I've devoted a fair portion of my time to contemplating airships, primarily because they're awesome. Fell out of use with the rise of much faster aircraft, and the technology its fate sealed by the extraordinarily bad rep the Hindenburg gave it. It is still far from useless, however, in that lighter-than-air systems can lay claim to flight times measured in days, and sometimes months, thanks to the fact that they literally float in the air like a boat floats in water.Their day may have come and gone, but I still want to experiment with the technology and create some model airships of my own. Helium works okay as a lifting gas, but it remains expensive and isn't going to get any cheaper in the foreseeable future. It is for this reason that I am pursuing hydrogen, in the hope that I might be able to produce a cheap lifting gas for my projects. Unfortunately for my aspirations, hydrogen is surprisingly hard to get cheaply in decent quantities. Here's what I've figured out so far.For one, it is absurdly hard to find sites that don't veer into fringe science when talking about hydrogen. HHO production, Joe cells, power your car with water...it all keeps cropping up, and not only does none of this do what I want, the concepts are often poorly documented or riddled with problems. However, I have been able to glean some information from my research. First off, one of the easiest methods (and the one I'll be pursuing the most) of hydrogen production is through electrolysis. For those of you unfamiliar with the concept, you can basically take two electrodes, stick them in water, add some electrolyte (like regular table salt), and apply a decent voltage. You'll get hydrogen gas streaming out of the negative electrode and oxygen out of the positive electrode. Fancier systems use large tanks, platinum electrodes, and a strong acid or base as the electrolyte. To increase efficiency (yeah, it's not 100% efficient), there is ongoing experimentation with high-temperature electrolysis and ongoing research into an effective electrocatalyst.Now, when I did my research, I thought "Hey! This sounds easy! I'll just set the system up like explained, and away we go!" Unfortunately, those exclamation marks were unwarranted. My first attempt showed that production is mind-numbingly slow with small electrodes. Using salt had the wonderful side-effect of producing chlorine and sodium hydroxide, a.k.a. caustic soda. It's called that for a reason, and I'm lucky I didn't run it too long or I might have a chemical burn now. Now I know. Choosing a good electrode turns out to be a problem too, as most conductors oxidize quickly or dissolve in the solution (now I know why everybody uses platinum when possible). My aluminum foil electrodes in a sodium hydroxide solution? Yeah, that didn't work AT ALL. I had better luck with steel mesh, but I recently found that it seems to fail over time too. The only thing that isn't disappointing is the container and the collection apparatus: an inverted plastic bottle with some airtight hose running off it, connected to a gas valve. If the bottle is placed such that forming gas causes the internal water level to be lower than the external container water level, the gas will be pushed through the hose (no pumping necessary!). There was one good thing I discovered, however. Apparently there was a bit of soap or something left over in the container, and I ended up forming a bit of explosive foam as well. The hydrogen foam blows up like nothing else, and the oxygen foam makes a loud pop and sends (slightly) caustic foam all over the place. Totally useless but still somewhat cool, so long as you're not fool enough to do it in large quantities.So, as of right now, I've got a good container and collection system, but my electrodes suck and production rates are so low that it'd take me hours and hours to inflate a good-sized balloon anyway. I'll be using sodium hydroxide in the future as the electrolyte, skipping the chlorine production and observing the proper safety procedures. My top priority is finding a good electrode, my next is finding a good way to increase surface area, and my last is getting a higher voltage source than the 12V power supply I had lying around. Any ideas?

Pedal-powered airship gets half way...

A French amateur pilot's attempt to be the first to cross the channel on a pedal-propelled airship has failed.Stephane Rousson, 39, from Nice, took off from Hythe on the Kent coast at about 0800 BST and was half-way to the French coast by 1300 BST.But he was hampered by a change in the wind direction and called off the trip 11 miles from Wissant in France.Mr Rousson said: "I'm not disappointed. I feel happy because it had nothing to do with any technical failure."During the challenge, Mr Rousson was suspended underneath the balloon envelope in a carbon fibre gondola, powering the two propellers with his feet using a bicycle-like contraption. The most amusing thing about the whole trip is the safety system:Just in case Rousson found himself flying irretrievably high, he hung an open penknife from the gondola framework, with the intention of popping the balloon and heading for a splashdown.Sorry, that's the second most amusing thing. The most amusing thing is the pilot's childhood inspiration - ET.BBC article

I would like to make a steampunk-style airship/zepplin for my baby's nursery?

I'm trying to create a modified steampunk nursery for my baby boy (let's call it "steampunk lite".) I would like to make a steampunk airship to hang from the ceiling, but I'm not sure how to start. I could buy a zepplin model kit, but I am hoping to get some ideas about how to modify it. Has anybody done anything like this or does anybody have any ideas? Thanks!

Can a vacuum balloon be built with current material technologies? Answered

A balloon's bouyancy (lifting force) is a function of how much air it displaces. Today's balloons use hot air, hydrogen, helium and other lighter than air gases for lift. In 1670 Franceso de Lana, an italian monk, proposed the use of a vacuum. One major problem is how to make the structure light enough to support a vacuum without collapsing in on itself due to the outside pressure.

Abney Park: (The semi-steampunk/weird genre of music group) :D

Abney Park comes from an era that never was, but one that we wish had been. An era where airships waged war in the skies, and corsets and cummerbunds were proper adventuring attire. They've picked up their bad musical habits, scoundrelous musicians, and anachronistically hybridized instruments from dozens of locations and eras that they have visited in their travels and thrown them into one riotous dervish of a performance. Expect clockwork guitars, belly dancers, flintlock bassists, middleastern percussion, violent violin, and Tesla powered keyboards blazing in a post- apocalyptic, swashbuckling, Steampunk musical mayhem. - quote from they're myspace page Band WebsiteBand Myspace

Heat powered cooler?

It's rather warm around here. And by "rather warm," I mean it's 105 in the shade, and it's 89 in the house with the swamp at full blast. Does anyone have an idea for powering a cooler with pure heat? Perhaps similar to those lightbulb-looking devices that have an inner bit that spins around when placed in direct sunlight, except that is running a little generator that is then running a computer fan, like the ice box air conditioner spotted on this site. The main thing is I'd like the device to actually be powered by heat. Just for the heck of it. Even if it's just heat mechanically powering something to power a fan that I could have just plugged into the wall. So no solar cells making electricity. I can make parabolic reflectors easily if needed, so don't be afraid to use them. What's the best way you can think of to cool off using heat? "Best" can include inefficient but really awesome, like a fresnel lens pointed at a boiler that is providing steam to run a gigantic fan. I'll go get my goggles, ray gun, and keys to the airship.

How clouds act as an air pump to suck in air. Not how you think they do!

I have been thinking a long time about the biotic pump theory but I still don't understand it.  The math is too hard for me.   BUT it got me to thinking.   It is a point of major dispute in the meteorological world.   Does condensation cause low pressure?  2 russian nuclear physicists say yes,  almost everyone else says no!   So,  I thought and thought and thought.  Now I think I have a simple enough explanation And yes, they may not necessarily cause low pressure under the cloud (probably do)  but they definitely suck in air from elsewhere.  Imagine a fleet of huge doughnut shaped dirigible airships. They are sitting at 10,000 ft just floating there.   Now the commander tells everyone that they must now fly at 5000 ft.   So they turn on their propellers (in the hole in the doughnut) and drop down to 5000 ft by propelling air up  through the hole.   Now staying at 5000 ft is achieved by running the propellers at just fast enough.  So at 5000 ft they are pumping air from under the doughnuts to above them.   Now imagine a cumulus cloud.  Even though it is not fixed in size or shape and it does not have a propeller,  it is doing the exact same thing.  Air is being pumped up the middle and the clouds are sitting lower in the sky than they "should",  because they are sending that column of air up into the sky.   Here is my video to explain it visually.  https://www.youtube.com/watch?v=sPO8dWm_GIg

The real gas guzzler: Car that turns hydrogen into electricity hits the road

Car that turns hydrogen into electricity hits the roadIntroducing the family car that runs on hydrogen and pumps out only pure water from its exhaust pipe.Honda's FCX Clarity is the world's first production hydrogen-powered 'fuel cell' car - with its own onboard power station which creates electricity to drive its motor.It has a range of 280 miles and a top speed of 100mph, yet emits no harmful pollution. And it is about to become the latest 'must-have' accessory for the Hollywood set wanting to show off their green credentials.Just the thing at a time when oil prices are rocketing to record highs. The only drawback? Finding somewhere to fill it up.The FCX is the result of nearly 20 years of research and many prototypes by the Japanese firm.It is being launched first in California where Governor Arnold Schwarzenegger has spearheaded the creation of a chain of hydrogen filling stations - as part of his environmental drive for cleaner cars. The first five customers include movie actress Jamie Lee Curtis. Honda claims the FCX offers three times better fuel efficiency than a traditional, petrol-powered car.The highly explosive lighter-than-air gas - which once kept the ill-fated Hindenburg airship in the air before its fiery end in the 1930s - is kept safely in a pressurised tank in the boot.Honda plans initially to produce about 70 of the eco-cars a year. They are initially available only to lease for around £300 a month including insurance - equivalent to a purchase price of £24,000.But Honda admits that the billions it has spent on research means that the true cost would be more like £1million per car.British motorists will have their first glimpse next month at the British International Motor Show in London's Docklands. Although there are price issues, its great to see there's development of this idea. I hope this sort of car is available for the "common man" at a "common price" soon.......

Within the context of NASA AMES Research Center* we feel our contemporary relationship to space and sense the incredible possibilities for the future of human and robotic space exploration.Simultaneously, this place exudes a feeling of another time, a time of science fiction fantasy and early space exploration and its potential for fulfillment, some ideas made real, some not: rocket ships of the past, an International Space Station of the present and airships of the future, flying cars, and time machines, terraforming, robots, and settlements on other planets. We will share an interpretive journey into outer space starting with the arrival of 'space cadets' at NASA * Ames's Yuri's Night Spaceport who, after a communal 3-2-1countdown to LIFTOFF! will jettison into a magical journey through time and space, as we discover new communities, interactive art installations, science and technology demonstrations, performances and space art interwoven with simultaneous influences from the past, present and future educating us to new possibilities socially, ecologically and technologically. We will reach the zenith of our journey as we sense 'The Overview Effect', an unexpected gift given to many astronauts who travel into space when they gain a new profound insight and understanding of our planet Earth, when confronted with the presence of our world as seen from the distance of space. The results of this experience can reinforce personal sensitivity to environmental conservation and the greening of space and 'The Overview Effect' has the capacity to transform all patterns of human existence and evolution toward greater potentials in human diversity and creativity. With all 'space cadets' having experienced changed perceptions of space, time, sound, and weight all we will have the potential to transform the evolution of humanity as they experience a new dawn on planet Earth.In creating Yuri's Night together, we create a new narrative, a new science fiction for the future and given the spirit of Yuri's Night, our night, our dance is a dance of inspiration, joy and celebration!Special notices:Unfortunately, despite our desire to do so, we cannot accomodate traditional media in the form of paintings, drawings, or prints.
