Hi guys,

I'm developing SHOGEN (Separated Hidrogen Oxygen Generator). you can watch my video here http://www.youtube.com/watch?v=Sf8h6_JzqVk , I've succesfully separate hydrogen & oxygen into 2 chambers that makes us can harvest each gas without effecting unbalance pressure to the other.

now I'm developing for the storage for the gases.
as far as I know there are 3 types of storage
1. pressure tank
2. liquefy
3. sponge (physically or chemically)

I'm interested with the sponge, does anyone understand about it ?
