This represents just about all that can be usefully given away, says a senior U.S. Agriculture Department official. He argues that most poor nations (the polite expression used to be underdeveloped countries, but now planners speak of "emerging peoples") lack the distribution system necessary to get large quantities of free food to the people who need it-partly because their governments have not yet accepted moral responsibility for ensuring that every citizen should get an adequate diet. "And if the U.S. offered to construct such a distribution system," adds the official drily, "I do not think such men as Nehru...
...that this will continue until the Nationalist government provides new incentives for investment in export industries. Private U.S. investors have put only $54 million into Formosa, partly because they object to the terms of Formosa's foreign-investment law, partly because of sad experience with the widespread "squeeze" system, through which some Formosan officials almost seem determined to run foreign businesses out of the country, not bring them...
From Nose Cones. Most of the electricity generated by the system comes from the electrodes, but waste heat can be harnessed to drive a conventional turbogenerator, adding importantly to the system's efficiency. Overall, Avco scientists estimate that a 450,000-kw. coal-fired MHD generator will produce electricity with the sensational thermal efficiency of 55%. The best that conventional plants...
Even more exciting is the possibility of using the MHD system with a nuclear reactor. In this case the gas will probably be argon or helium, laced with cesium to make it more conductive. It will circulate through the reactor, then through the generator and back to the reactor again. This system will have to wait for the development of high-temperature reactor cores, but Project Rover, the Atomic Energy Commission's nuclear-rocket program, has shown that the prospects of this are promising...
...solid-fuel rocket, too, is simple and vastly promising-but difficult. Chief problem is to get the fuel to burn dependably in such a way as to provide a precalculated, controllable thrust. In the liquid rocket this is done by an intricate system of gas generators, pumps, valves, turbines and tubing. But this advantage is also a source of trouble, because failure of one or more of these intricate parts is the usual reason for the frequent liquid-rocket misfires...
