<br />Among the most recent attempts to parness the power of the sun is <br />that of the Bell Telephone Laboratories. their technicians came through <br />with what they term a Bell Solar Battery, tated at a generation of five <br />volts. A combination of absolutely pure silicon, couples with arsenic and <br />boron gas, when exposed to sunlight was found to generate electrical energy. <br />Weak as the output is, it is a .step in the direction that Bell Telephones can <br />use to tremendous advantage. Electrical power in remote installations is <br />often nearly prohibitive in cost of transmission and so what may appear to <br />be an appealing and ingenious toy, in reality may become a very practical <br />solution to powering telep40ne conversations. Experimentation is also <br />being carried on with tran~istors to explor.e the possibilities of radio <br />communications. <br /> <br /> <br />At the present stage of the experimental work, it is almost impossible <br />to make a prediction as to the potential of the future, but this we do know, <br />any really practial mechanical machine has never failed in the American <br />industrial world, once it stepped from theory to production. We are not <br />doing so badly right at the; moment because the Bell Solar Battery is 80;0 <br />efficient now and we have .reason to believe that we can raise that 8% to <br />23%. Compare that percentage with your modern automobile engine with <br />its rating of 6%. <br /> <br />Notation: After these preliminary remarks, Mr. Dodds proceeded with a <br />demonstration of the Solar Battery and other devices of technical <br />and scientific inte re st. <br /> <br />******** <br /> <br />_ PANEL DISCUSSION - <br /> <br />WHA T WI,LL BE THE EF FEC T OF A CONT INUED <br />DROUTH IN THE COLORADO RIVER BASIN? <br /> <br />Hugh Shamberger, Moderator <br />Nevada State Engineer <br /> <br />j <br />~, <br />i <br /> <br />Mr. S ha m be r g e r: Our Panel is comprised of Mr. Noel Pike, Engineer <br />with the Arizona Power Authority: Mr. John C.
