Unlimited Air

[Skittle]

Ive had this idea for sometime now, and I always thought it was just rediculous and impossible. However, after seeing some of the stuff you guys pump out, nothing is too rediculous.

My idea is for unlimited air, it would screw into your asa and be about as big as a stock class 12g adapter. It would be like a small jet engine, it could create a continuous suction constantly keeping air in the marker. No more fills, no more tank....

What do you guys think?

battery powered??

[rb211]

I don't know, JET-A is getting pretty expensive............

1. I dont think you would get the recharge rate fast enough
2. You would not get high pressure maybe 100 - 200 psi
3. You would end up changing air filters every 5 minutes after diving into the snake and running some sand through your marker.
4. Kids on pbnation would stick their fingers in the fan
5. Probably be pretty heavy with the batteries to run the fan.

I think the idea of a closed HP tank works for me its just simple and its either is working or its not.

Very creative
The only two problems I see with it is this:

1)If it's battery powered (most likely) it wont have the power to deliver high psi. Even if it could barely deliver the needed psi the recharge would be horrible.

2)It would no doubt sound like a shop vac also.

I think a step in the right direction for this idea would be to couple it with a small HPA cylinder. Assuming you could pump high enough psi with the jet, the small tank would be a buffer for stringing shots together.

I very creative idea, but I think practicality might outweigh the benefits of a new system. Then again, i could be wrong and everyone could own one in a year.

hmm, well if you need sort of a buffer chamber... mabye you can make it like a mag valve.

if you took the mag valve, put it on an asa... and make it suck in air, it may be good. espically sense it has such a nice recharge rate.

As above...
- Where would you get the energy to run the compressor?
- Where would you find a compressor that small able to keep up w/the rates of fire required and silent enough.

There was (is?) an electric paintball marker available that functioned on the same principle as a lot of pellet guns. An electric motor was used to compress a spring connected to a piston that when fired would compress air & use it to fire the ball.
I believe it didn't have a phenominal ROF & the weight was probably comparable to a marker w/a steel HPA bottle (if memory serves). The only advantage was that the battery pack doesn't have to be a specific shape like an HPA tank.

A paintball requires a certain amount of energy to accelerate it to 300fps. Currently that energy is contained in our bottles in the form of compressed air. It takes energy to compress the air. So, basically everything is a transfer of energy. It starts out as fuel or electricity, and through the use of a compressor is transfered into compressed air that is stored in our bottles. When we fire the guns, the energy is transfered to the balls. The balls release the energy when they hit something.

You have to consider how much energy is stored in the air and how much energy it takes to compress the air. Ask yourself the question, "How big of a battery would I need to run the compressor that pumps the air to fill my bottle?" That would essentially be the same size as the battery you would need on the gun to run a compressor.

tank

The propane thing is a better idea. You still have a tank and it has to be replaced but the amount of shots you get is amazing. I believe 50,000 from the big propane stove tank like the new tippman used. Propane requires a totally diff marker design but I see no reason why somthing like the modern electros could not be built. Since you would not need the LPR it could be replaced by a chamber like the old 12gram guns took and propane could come in 12 gram sizes. One 12 would give you I am guessing an easy 500 shots.

Rats, I was going to say that but you beat me too it.

The jet engine idea would require fuel, so it's not really unlimited anyway ... perpetual motion machines will never exist ... so what you're saying is fuel > engine > propellant force. The new Tippmann propane markers eliminate the middleman if you will; fuel > propellant force. You will most likely use less fuel this way too so you have to carry less of it for the same amount of shots.

It's like the early steam powered cars vs internal combustion. With a steam powered car you need fuel to heat the water to create steam to drive a piston, with internal combustion you just use fuel to drive a piston and bypass all the intermediate steps.

[Teamslayer76]

Pbnation kids lol That cracked me up.

I was also going to link to the evolt. Then the propane idea is great but would it work semi-auto. I'm not really sure about the details of the propane situation.

That's a good analogy!
What we are using now - compressed air or CO2 is basically the steam engine without the boiler, just a bottle of steam.
When you look at the size of the "boiler" - the HPA compressor or the industrial processes that create the CO2 we are using then you are seeing the size of the power source.

If you made it to suck air in, you have to create a low pressure area, and air will come in to that. Which means you could get a whopping 14 psi (atmospheric pressure.) Considering that there will then be 14 psi in front of the ball, and 14 behind the ball, the paintball won't leave the paintgun.

Pushing the air in and compressing it would probably be more productive.

Ouch.

Those simunition thingies hurt.
