• Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

E-bikes are so last week, new thing is... air bike...

Cool idea, says similar to e-bike distances and lighter. No batteries. Thats a diving tank in the middle.

That's way cool!
Nice to get another take on energy sources- fill ups must take NO time compared to Electricity- that's a big plus. Air is weightless- so it must have some advantage there as well. INteresting- very interesting!
Sharp looking bike too!
 
Looks like the band RUSH called it way back in 1981 with the song "Red Barchetta"... "A gleaming alloy air car shoots toward me two lanes wide..."
 
I sure would hate to be sittin' on that thing if the bash plate gave way and a rock punctured the tank! Air bike becomes air rocket! :eek:
 
Ummmmmmmmmmm, no thank's. I've seen pictures of what an exploding air tank can do.

3200 PSI.

A dive shop here in Ontario was gutted when a tank blew while being filled, killing the shop worker. I treat my tanks with great respect. Bouncing one off a boulder just ain't smart.

Think of the old Ford Pinto parody's times ten.

Ever seen what 3 gallons of gas can do?
 
Love that thing!!!
Might drive the price up a little but they should have a Scott Air cylinders (same as the ones we used for Fire & Rescue). They are made of aluminum and carbon-fiber wrapped. Holding 4500 psi. with a burst pressure of 12,000 psi and only weigh 5kg.:D
 
This modern day concept has been around for a few years and they have multiple physics issues to over come ... Put your money on the guys from MIT and their flow-batteries ...

And air engines are nothing too new ... its really hard to do something really new ...

The first successful application of the pneumatic motor in transportation was the Mekarski system air engine used in locomotives. Mekarski’s innovative engine overcame cooling that accompanies air compression by heating air in a small boiler prior to use. The Tramway de nantes, located in Nantes, France, was noted for being the first to use Mekarski engines to power their fleet of locomotives. The tramway began operation on December 13, 1879, and continues to operate today, although the pneumatic trams were replaced in 1917 by more efficient and modern electrical trams.

When a gasoline tank is ruptured, it drips because it isn't compressed. Couple that with the fact that it would need a source of ignition to set off an explosion.

When compressed gases are liberated from a containment vessel, the results are immediate and usually catasrophic. When flammable compressed gases (not like the air being used on the O2 bike) are liberated from a containment vessel and ignited... hold on to your ass!

I've seen training videos of compressed gas cylinders being breached. It ain't pretty. In fact, it's damn scary! :eek: If the cylinder on that O2 bike was ruptured while under pressure, the likely outcome for the rider would be horrific.
 
The energy used to compress air makes a lot of heat the energy you could possibly get back when un compressing it....... This is a loss of credibility of those advancing this idea. Remember the big lie neuclear power too cheap to meter? I guess air tools are kind of neet a lot of power to weight but the compressor needs to draw close to an order of magnitude more amps (or kilowatt hours if the voltage is more on the compressor) than if you did it with an extention chord and an electric tool. If one really wanted to you could figure out the thermodynamics. I saw a scuba tank get filled, it took a six stage compressor making quite a racket for 10 or so minutes. This o2 must be a name right? Are we going to freeze air seperate it into nitrogen oxygen and argon and use the oxygen for this purpose? This is storage device not fuel some of this stuff gets mis labeled.

It would be like sitting on a large hand grenade.

It's the same thing for the welding business. Some of the tanks used for the compressed gases are holding upwards of 4500psi. & the average O2 tank for torches is at 2500 PSI when full.
We were always trained to never remove the safety cap until the tank is fully secured. A couple guys were killed in Toronto a few years ago when a tank, which had the safety cap removed, fell over while being moved in the back of a truck and had the valve knocked off. The tank took off like a rocket, bounced off a brick wall, came back into the truck and took them both out.
If the container gets breached it's even worse.
I used to have to remind guys in no uncertain terms to not be lazy&careless about handling O2 tanks at the one press shop I worked in. One dumbass dropped a full one while moving it around without the safety cap on. Thank god it landed ok. Boy did I tune him in after that one!

Granted, in this application, the cylinder could be better protected & reduce the risk of rupture to almost zero. But, the other issue is that pressure vessels need re-certification every so many years.
Other than that I'd like to ride the prototype and see for myself how it works.
 
Don't shoot the messenger, I was just posting some new cool project bike, its not like i am going to run out and buy one :D I think the idea is interesting as it is light, Ez to swap out or refill and could be packaged pretty safe. Also like that there is no nasty battery chemicals so spill out of or dispose of after the life of the bat. Lots of advantages to the idea. Cars run compressed propane and other gasses. Pintos exploded. Everything has risks.

Compressed Gasses scare me... Still have vivid memories of a flightline accident back in the 80's that I narrowly avoided... Hanging out with a crew chief filling a nose wheel tire on a F-15 which took about 250 psi (nitrogen) he attempted to put 750 in.. it cut him in half and sprayed pieces of him all over... had gotten done keying his jet and was shooting it with him.... then decided to see if I could get off early since I had completed all my tasks for the evening... best descision I ever made...happened after I passed the tail boom on his aircraft.... took up smoking and drinking again that evening.....

Agreed. :thumbsup: I Didn't mean to be against the idea outright in my specific post, only echoing some known issues, some of which affected me personally. Other than that the concept seems neat.
 
If it uses compressed gas, it should also be able to run on methane, a product of sewage farms. So then (a) it would effectively run on faeces and I could ride on my own cr*p and (b) Husky could make a bike that was no longer lardy and could even be lighter than air.
 
Larry the cable guy had an expermental car that ran on his methane. He was pretty happy with it till one day he went throught the drive thru at Taco Time. I guess the engine flooded and wouldn't restart.
He didn't say wether it was carbed or FI.
