...assistant director and senior research fellow, said Tuesday that the bubble chamber, for safety reasons, probably will not be returned to the CEA experimental hall. The hall was devastated by an explosion July 5. Most observers, Collins said, now believe that the blast was touched off when liquid hydrogen being fed into the bubble chamber spilled onto the floor...
...graphite-but it languished until researchers began to coat nose cones with it to resist high re-entry heat. Next month California's Super Temp Corp. and Tar Card Co will begin marketing $8.95 tobacco pipes lined with pyrolytic graphite. The fuel cell, which generates power by converting hydrogen and oxygen into electricity and water, was a laboratory curiosity until General Electric put it in Gemini. Now General Dynamics is using the fuel cell to produce electricity aboard a one-man submarine, and Allis-Chalmers is using it to power experimental spot welders, golf carts, tractors and forklift trucks...
...trickle of oxygen became a steady stream, joining in a chemical reaction with hydrogen to produce the electricity to run the craft's computer, radar, communications and environment-control systems. For reasons not yet fully understood, the pressure inside the oxygen tank increased as the volume of liquid oxygen decreased while it was being used. Soon the fuel cell was supplying Gemini with all the electricity it needed, and the astronauts began switching their systems back on. Fuel-cell experts had actually underestimated the system's efficiency, were surprised that they could get sufficient power with such...
...into a drifting, tumbling flight. They had to scrub some of the remaining photographic experiments that required them to use the thrusters to get into a picture-taking position. Ground control was also worrying about the fuel-cell system again. The process of generating electricity by mixing hydrogen with oxygen was producing much too much of that inevitable byproduct: water. Ground control feared that the spacecraft was running out of storage space for water and that it threatened to back up into the cells and knock them out. Kraft informed Conrad of the problem and asked, "How's that...
...cell's hydrogen and oxygen are both stored in spherical tanks in a supercold liquid state. Warmed by electric heaters, they turn to gas, build up pressure and push themselves into the cells. And those heaters are among the least complicated devices on the spacecraft: a filament of gold-plated wire curving around the tank. The same type of device is a veteran of all the manned Mer cury and Gemini flights, being used to convert liquid oxygen into gas for the astronauts to breathe. When oxygen pressure started falling in Gemini 5, it was a sure sign that...
