Indeed, structural designs has much more to be refined, but Dave Scadden got something going on in the long run.
The cell system is a great design for all inflatable system. And you're dead on about monitoring the pressure being pumped into the cells. They need to heavily test the different conditions of the inflated pressures, listing the possible and heavily adviced not to do under the addressed pressure used. Imagine the honey comb air cell design implemented later, rather than the square shape supportive system. $$$ but worth the integrity when under pressure. As the shelling-protective materials improve over time, supportive air cells configuration integration become more essential to increase the max capacity of weight support, and tensile strength under stressed conditions. You have quite a bit of research ahead of you, as other major companies may already be developing and testing the designs now, but the costs may be too prohibited.
Can't wait to see what you will be coming out with in the future. Best of wishes on your success in forming the next fortune 500 company with your inventive design.
