A system and method for transmitting data communications through air using a radio. The H2 gas employed can be generated by electrolysis of water, produced by H2 evolving microorganisms, andor produced by legumes. A controller in the system allocates transmission of the common control information from at least one of the base stations over a physical channel having a defined transmission time and transmission frequency. The bearing block is clamped in the cut-out by a plate which is received in a pair of slots in forward and aft edges of the cut-out to clampingly overlie the bearing block. This is achieved by an appropriate feedback control circuit driving the DC-DC converter of each power module.
