Would anyone be interested in a product that keeps a constant pressure.. SET by the user.. In the gas tank as well as in a smoke take or any other tank?

I have made a smoke system w/o a pump, just a regulator valve attached to a servo and used a pressure system to do the pumping for me... It also keeps a constant pressure that I adjusted to the gas tank which assures me the same setting on the ground as in any position in the air.

If I could mass produce this system some how, do you think anyone would buy it?
