Guys found this on Rajan da's post and from then onwards had been reading about it.

What you all think?

here's the link

yes i have gone through it carefully.but the thing is gadgets like these may cost less in US but in our country the price may increase manifold.actually it is a combination of two regulators.
but the design is a good one and looks promising.

Rahul bro they are delivering in India free of cost. And the price will be around Rs. 1200 in Indian currency. Worth a try? What you say?

Rs.1200/- :-o ...that isn't tooo costly actually. Need to read more and specially reviews to assess the cost vs probable success. I would love to try this actually :D .

Here's the link actually for ones who are interested.

What I was thinking of is if we can get through someone who stays in the US. Maybe a friend/relative anyone of us have?
Cheers,

Basic setup for experiment purpose complete and it works. It is easier than i thought. Here is a small video of it working, just for quick demonstration purpose. Please comment.

Rajan da, the shipping is free to India. And price will be same even if someone buys in the US. what you say should we give it a try? I am interested.

Debraj, the video permission is not set to public. Pls check once. Could you pls share some more details like what proportion u folowed and how much time it takes,etc?

Sorry for that, it is now set to public. Since I intended to do a quick experiment, I did not calculate the proportions. Another thing is that I used vinegar instead of citric acid powder, as it was readily available at home, although it is not recommended as the gas from vinegar can dissolve in aquarium water. I used 2x600ml soda bottle. You don't need to buy anything except for a I.V. Drip set for this, it works perfect as a regulator. The gauge on the first bottle is not absolutely necessary, it is just for measuring the pressure which is not needed. Rather i would attach a emergency pressure valve on the first bottle. The only goal is to bring the total system in equilibrium. The output seems to be quite high. You can get a basic idea of the setup from the pic i have attached below. :D

Nice one Debraj... :-bd
So I think Citric acid & baking soda system can be turned off when required (dark-period) so it has an advantage over Sugar & yeast generator.

Now some questions....

1) Do we have to squeeze citric acid bottle daily to start the reaction? or it readily gain the pressure equilibrium when turned on the switch??? :-\
2) As I have no idea about IV drip set, I think is you are using it to on/off switch purpose and also as a check-valve. Am I right?? Correct me if I am wrong..... :ymsick:
3) How efficient this system is?? I mean how long they run??? Any hands-on previous experience???
I have learned how to be a learner.....
