Perfected after six years of research, the sophisticated AMU (for Astronaut Maneuvering Unit) that is built into the space walker's backpack will give Bassett singular agility. It is powered by twelve small hydrogen peroxide thrusters that can propel it in any direction; it has its own fuel tanks, running lights, gyroscopes, and an alarm system that warns the wearer by flashing lights and sounding beeps in his earphones if fuel or oxygen is running low. With its own hour-long oxygen supply, storage batteries and radio and telemetry systems, the AMU does not even need the "umbilical cord...
...Hydrogen Cooling. These apparent limitations dampened interest in further ramjet development work until late last year, when Marquardt Corp. scientists convincingly demonstrated a practical method of maintaining combustion in a supersonic flow of air. Using hydrogen, which has a low ignition temperature, burns rapidly and provides high thrust, they kept an experimental scramjet burning in air moving as fast as 7,000 m.p.h. By redesigning their engine's inlet to allow it to gulp air at supersonic speeds, they were also able to eliminate the excessive temperatures and pressures. And they proved that useful thrust could be produced...
...hydrogen fuel also promises to pay an extra dividend. To be kept in liquid form, it must be stored in refrigerated tanks at a temperature of - 423 °F. And since a plane moving at scramjet speeds will be seared by the heat of friction as it moves through the atmosphere, the frigid hydrogen will make an ideal coolant to be pumped through the skin of wings and fuselage before it is burned...
...industry, the byproducts of a cleanup often offset part of the costs. Los Angeles County's oil refineries strip smelly hydrogen sulphide from crude oil, convert it to 450 tons a day of marketable sulphur. Boston Edison Co. mines vanadium from its oil-fired smoke, exports it to Belgium. For the nation, air and water cleanups mean a huge saving in dollars as well as in health. An air cleanup alone would save $11 billion a year that is now wasted on extra cleaning, painting, corrosion and damage to crops and property...
...next July, the CEA will also reactivate a small bubble chamber it used in the early part of 1964, Livingstone said. It holds 32 quarts of liquid hydrogen when full -- only 1/20 the capacity of the larger chamber -- and will permit the continuation of a few bubble chamber experiments...
