Thank you very much to all of you, for encouragement and suggestions. To the best of my knowledge, the Batteries are heavy in weight. In my calculations, the Tubes, whether inflated with Air Pressure or not, will not be having any weight, if at all it may be < .5 kg. I think so.
Secondly, I want to check, when we release the Air Pressure out, will this gives ’ Jet effect ’ to Push forward the cycle,if so, it will be good.
