.wer from the Sun by Gordon Kwan fl25Bl Picture yourself thirty years om now, sitting at home watching levision powered from outerspace. lat is, power beamed down to rth from solar satellites that pture vast amounts of the sun's ergy. In the near future scientists NASA plan to put a solar satellite to space that could capture the in's energy and convert it into ectricity, which would be beamed wn to earth in the form of crowaves. The satellites would insist of two giant arrays of lar cells, each about three les long by two miles wide and igh about 50,000 tons altogether. would be placed 22,300 miles love the earth in geosynchronous bit, there the structure's orbital eed would match the planet's itation, thus holding the solar iwerhouse over the same spot on ie ground. Because of the fact that the tellite sends microwaves down - the earth, power would be pplied even on cloudy days or ring the night. The beams iuld focus in six-mile by nine- le oval shaped receiving antennas. ese antennas would turn the crowaves back into electricity d funnel the power into utility fids. One satellite is timated to be able to supply much energy as five nuclear iwered planets. However, like all great ideas, ere are certain problems. One fvious problem is the cost. e cost of one satellite is .timated to be about S100 llion. Another factor to consider . the problem of microwave adiation. The satellite is instantly sending down microwaves d people in passing pl509S Could - exposed to the radiation. other problem with the satellite - its size in that it is too large o be constructed on earth and, erefore, it will have to be onstructed in space. The materials cr construction would have to be :rried by spacecrafts that have vt yet been developed. when in face, most of the construction orkers would have to work in it or months at a time. That eates another problem of homes or the workers in space. Certainly, there are many problems in this project. But with man using his recent resources the way he is, space satellites will have to be used in the very near future. Farm Carts and Wagons by Albert Lomoro CllTwl In many respects the wheelwright's craft is similar to that of the joiner, but whereas the joiner may rely on glue and dowels to strengthen his work, the wheelwright must rely on the tightness of the joint alone to hold his work together. Traditional glues would simply disintegrate under the constant flexing and jarring, wetting and drying that are used for a lot of farm vehicles. The quality of the timber was so important to the wheelwright that he himself would supervise the felling of the trees and the sawing of the wood. Each piece that was delivered to the yard was assigned to a specific task, gently curving pieces of beech and ash would be set aside for felloes. Straight oak butts were used for cleaving into spokes, curving ash was used for the shaft, and straight grained oak and elm for the frame and boarding of the wagon. 0ak and Ash were the principal timber used in framing the wagon, but different styles developed in Britain and Europe. The four wheel farm vehicles of Europe had simple straight sided bodies of oak which were extremely strong but which restricted the turning circle of the wagon. English wheelwrights, designing their wagons for use in narrow lanes and yards, overcome this by making the wagon in two parts - the narrow waist allowing the front wheels to turn more sharply. The flooring of elm planks could be laid either along the length of the wagon or across the width, depending on the loads to be carried. For sand, gravel, or manure loads, all of which must be shovelled, long boarding was preferred, with cross boarding, an elm slat might curl up in the path of the shovel. For side-members, ash was generally preferred, often in combination with popular. Not all country working vehicles, however, are the work of skilled craftsman and, in many parts of the world, particularly in remote regions, the farmer must make his own carts from whatever material is available. In China, oak and elm are used but with rosewood taking the place of oak for many purposes, whilst the ever versatile bamboo is pressed into service for vehicle construction throughout many far-eastern countries. The Loved One by Paul Karas Cl0TGl It was to his concern, yet her aid That in the garden, she be laid. Among the lily and the weeds She would rest, for eternity. And all the people would come, To recall the times, they had with her before the closing of the door. Giving flowers to her home and love from down deep, A tear is shed, for one who is dead.
